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. {76}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. [male].--4. [female]. ORDER: Coleoptera. SECTION: Lamellicornes. FAMILY: Dynastidæ, _MacLeay_. GENUS. DYNASTES, _MacLeay_.

The Great Brown Sawyer, _Brown's Jamaica, p._ 428. _t._ 43. _f._ 6. HABITAT: Jamaica. _Male._ Head black. 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.
