406 CLASS INSECTA. 



saw-form, and composed only of three articulations, of which 

 the first and last especially, are larger. 



The body is ovoid, short, and but little convex. The last 

 articulation of the maxillary palpi is larger and ovoid.* 



Trogoderma, Latr. Dej. Anthrenics^ Fab. 



In which the knob of the antennas has four articulations at 



the least. 



The body is ovoid, oblong, and the palpi are filiform.f 

 Now we find the knob of the antennse solid, or composed 



of very close articulations. The body is ovoid, short, all 



covered with small perishable scales. The corslet is lobate 



posteriorly. 



Anthrenus, Geoff. Fab. Byrrhus^ Lin., 



Whose antennse terminating in a knob, in the form of an 

 inverted cone, lodge in short cavities, made under the ante- 

 rior angles of the corslet. 



These Coleoptera are very small, live on flowers, in their 

 perfect state, and gnaw, in the larva form, dried animal 

 substances, especially insects in collections. These larvae are 

 oval, and furnished with hairs, many of which are denticu- 

 lated. They form aigrettes, and the final ones are prolonged 

 behind, in the manner of a tail. Their last skin serves as a 

 shell for the nymph.
