TRICHIAD/E. 139 



DESCRIPTION. 



Body obovate, black; covered, particularly underneath, with longish pale hairs. Head very 

 thickly punctured ; nose reflexed, emarginate ; stalk of the antenna?, excluding the scape, testaceous : 

 prothorax suborbicular, with the segment of a circle taken out next the head ; very thickly punctured, 

 channelled, sprinkled with short yellowish hairs ; at the side of each of the four angles is a mealy- 

 white spot : the elytra next the lateral margin have two transverse mealy-white streaks or bands, 

 which are continued towards the suture by a broader, naked, ferruginous, obscure band ; just below 

 the scutellum, on each elytrum, is another mealy stripe, and parallel with the suture is an obscure, 

 naked, ferruginous one : podex hairy with the ordinary mealy pale spots very conspicuous ; it is 

 sculptured with transverse undulated lines : cubits robust with two stout teeth : a mealy spot marks 

 the base of the posterior legs.

 Verdant T. Trichinus, above green, underneath with pale hair : prothorax subtrapezoidal, channelled ; elytra with two 



bands internally testaceous, externally, as well as a line before the scutellum, mealy-white.

Length of the body 4j lines. 



A single specimen taken in Canada by Dr. Bigsby. 



DESCRIPTION. 



In the markings of its elytra this species agrees precisely with that last described, but the upper 

 side of the body, especially the head and prothorax, is green ; the latter is of a different shape and 

 less thickly punctured ; and the cubit and its teeth are less robust : the podex also is more hairy. 

 These can scarcely, all of them, be mere sexual distinctions. 



It seems intermediate between T. rotundicollis and T. viridulus. 



xi. * Subgenus Gymnodus. Kirb. 

 Gymnodi. Kirb. Zool. Journ. iii, 157, *******. 



This is a very natural group of the genus Trichius, the species of which are 

 common to Europe and North America. The type of it, T. Eremita, has long been 

 known as a European insect. It was first noticed and figured by Rosel, and re- 

 ceived its present name from Scopoli. 1 The species that compose it are nearly 

 naked, and without any mealy spots : the nose is truncated, and the cubit is tri- 

 dentate. It appears to make a near approach to the South American Goliathi.
