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 dififerent 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.

Male. Head black. Antennae 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. Tibias 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, i#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.
