Habitat: Sierra Leone (Drury). "In India Orientali, Africa" (Fabricius). Head and thorax black; the latter terminating in a horn near an inch and a half long, standing almost erect, but bending forward and diminishing towards the end, which is forked, having a strong spine on each side of the front near the base. The head is furnished with another horn that inclines backwards towards the other, and at the extremity is curled and pointed, having a square knob placed on each side near the curl. Elytra dark brown, almost black, smooth and shining. TibiÆ armed with spines and hairs. Drury states that this insect was brought from Sierra Leone, and that it lives in the mangrove trees; many specimens having been taken from thence. TRICHIUS FASCIATUS.Plate XXXVI. fig. 2. Order: Coleoptera. Section: Lamellicornes. Family: CetoniidÆ. Genus. Trichius, Fabricius. Cetonia p. Oliv. ScarabÆus, p. Linn. Trichius Fasciatus. Niger, flavo-rufo-tomentosus, elytris atris fasciis duabus luteis internÈ confluentibus. (Long. Corp. 7-8 lin.) Syn. ScarabÆus Fasciatus, Linn. Syst. Nat. II. p. 556. Fabricius Ent. Syst. 1. 119. Donovan Brit. Ins. 4. pl. 140. Steph. Illustr. Brit. Ent. Mandibulata, 3. p. 230. Trichius Succinctus, Fabr. Ent. Syst. II. p. 132 (variety). Habitat: Germany, France, England. Head and thorax black, but thickly covered with yellow hairs. The scutellum black and triangular. Elytra tawny yellow, not reaching to the anus; having a black margin, and three large black spots situated on the lateral margin. Abdomen and breast black, and covered with hairs of a very light or pale yellow. Femora and tibiÆ black and hairy. The insect here figured is regarded by most authors as a variety only of the Trichius fasciatus. Fabricius, however, considered it as a distinct species, which he named Trichius succinctus. Dessau also, in the Bulletin des Sciences Naturelles (February 1829), has published some observations, in order to prove the specific distinctness of this and two other species with which it is generally regarded as identical. Its habits are different from those of the other Trichii; being generally found upon flowers, a peculiarity, with which its hirsute body and bee-like appearance apparently offer some indicatorial connexions. It is extremely rare in this country. DYNASTES TITANUS.Plate XXXVI. fig. 3. ?.—4. ?. Order: Coleoptera. Section: Lamellicornes. Family: DynastidÆ, MacLeay. Genus. Dynastes, MacLeay. Geotrupes, Fabr. ScarabÆus, Linn. Drury. Dynastes Titanus. Thorace tricorni, intermedio longiori apice bifido, lateralibus subarcuatis acutis, capite mutico. (Long. Corp. cum corn. thorac. 1 unc. 7½ lin.) Syn.

AntennÆ dark brown. Thorax black, smooth, and shining, and armed with three horns; two of which, being about one-third of an inch in length, are placed on the upper part on each side, lying almost parallel with the body. Beneath these, near the head, rises another from the middle of the thorax, which is a little longer than the two first, bending upwards, and forked at the extremity. Elytra rather rough and furrowed, but shining and black. TibiÆ armed with spines, especially at the extremity, which facilitate the animal in its passage. Abdomen black; anus with a row of light brown hairs. Female. Differs from the male chiefly in the thorax, which is entirely unarmed. Black and shining, but rather less so than the males; and in the front, just above the head, is a small impression. All the under parts of the insect which in the males are black, in this sex are of a dark reddish brown. In other circumstances it resembles the male. DYNASTES GIDEON.Plate XXXVI. fig. 5. Order: Coleoptera. Section: Lamellicornes. Family: DynastidÆ, MacLeay. Genus. Dynastes, MacLeay. Geotrupes, Fabr. ScarabÆus, Linn. Drury. Dynastes Gideon.

(Var. prÆcedentis.) Habitat: East India. General colour dark brown, almost black. Thorax smooth and shining, as if polished, and terminating in a strong thick horn, which inclines forward in a curved position, and is forked at the end. From the head also springs another strong horn, forked at the extremity, which in length corresponds with the first; its outer side being broad and round, but its inner side, or that opposite the other horn, is thin and sharp, having a small swelling in the middle. Elytra smooth and shining, with a narrow margin. Anterior tibiÆ with four teeth; two being at the tip, and two a little above them. The other tibiÆ are furnished with several sharp spines (five or six), chiefly about the tips; which, as noticed in D. Titanus, assist the animal in its passage. Anus not hairy, as in many other species. CYCLOCEPHALA SIGNATA.Plate XXXVI. fig. 6. Order: Coleoptera. Section: Lamellicornes. Family: RutelidÆ, MacLeay. Genus. Cyclocephala, Latreille.
