408 CLASS INSECTA. 



B. pilula, Lin. Oliv. Col. II. 13. i. 1. Three or four lines 

 in length, black underneath, of a blackish brown, or soot- 

 colour, and silky above, with small black spots, interrupted 

 by others more clear, disposed in lines. 



M. Waudouer has discovered the larva of a variety of this 

 species. It is narrow, elongated, with the head thick, the 

 plate of the first segment large, and the last two longer than 

 the others. It remains under moss. 



Another species (Sfriato-punctatus, Dej.) having the 

 antennae conformed in the same manner, forms, by reason of 

 its tarsi, the first articulation of which is very small, and 

 concealed between the lobes of the preceding, a particular 

 division. 



Another byrrhus, very small, and bristling with hair, has 

 antennae, terminated in a knob, with three articulations. 

 This species forms the genus Prinodes, of MM. Megerle 

 and Dejean. {Anthrenus hirtus^ Fab. Panz. Faun. Insect. 

 Germ. XI. 16). 



From this consideration we may also detach from the 

 Byrrhi some other analogous species (5. crinaceus, Zieg. ; 

 and B. setiger, Ulig.) in which the knob of the antennae is 

 composed of but two articulations, the last of which is much 

 thicker, and almost globular. 



All the Byrrhi generally remain on the ground, in sandy 

 places. 



N. B. The genus Murmidius of Dr. Leach belongs, ac- 

 cording to him, to this tribe. The antennae have but ten 

 articulations, the last of which forms an ovoido-globular 

 knob. 



We cannot mark the Clavicornes of our second section, 

 though very natural, but by the union of many characters. 

 Some of these insects are removed from all the other clavicor- 

 nes, by reason of their antenna?, with nine or six articula- 

 tions. These are they which, in this point of view, seem to
