330 CLASS INSECTA. 



not present that tint of pale yellow, or whitish, which affects 

 this part of the body in Lampyris (proper), and announces 

 their phosphorescence. The elytra, in many, go on widening, 

 and are even sometimes very much dilated and roimded pos- 

 teriorly, particularly in the females. They are very much 

 punctuated, and often reticulated. 



Lycus, Fab. Oliv. Cantharis, Lin. 



We shall confine this sub-genus to the species of Fabricius, 

 in which the muzzle is as long, or longer, than the portion of 

 the head which precedes it, and the antennae are serrated. 

 The elytra are most frequently dilated, either laterally, or at 

 their posterior extremity, and the two sexes differ much in 

 this respect, particularly in some species peculiar to Africa.* 



Other species of the same writer, but with a very short 

 muzzle, and whose compressed antennae, sometimes simple, 

 and sometimes serrated or pectinated, have their third arti- 

 culation longer than the preceding, and in which the inter- 

 mediate articulations of the tarsi are in the form of a reversed 

 heart, will compose another sub-genus, that of 



Dyctioptera, Lat., 



Which we find in some woods in the neighbourhood of Paris, 

 in the flowers of the millefolium, and others, and some- 

 times in abundance.

 XLI. 9. It is almost three lines in length, black, v\^ith the 

 sides of the corslet, and the elytra of a blood-red. These 

 elytra are silken, and slightly striated. Its larva lives under 

 the bark of the oak. It is linear, flatted, black, with the last

 for the other species the appendix of the third part of the first volume of 

 the synonimy of the insects of M. Schoenherr, in which he has described 

 and figured several.
