176 NATURAL HISTORY OF 



spots, of which the central one is longest and some- 

 what triangular. The elytra are very thickly co- 

 vered with minute punctures ; the colour blackish, 

 except the outer margin, the suture, and a broad 

 streak extending from each shoulder rather beyond 

 the middle, which are of a light yellowish brown. 

 The wings are black. It is found in Brazil and 

 other inter tropical countries of South America. 



The genus Lycus is distinguished by having the 

 snout longer than the hinder part of the head, and 

 the antennae serrated. The elytra are often remark- 

 ably dilated at the sides, and usually reticulated on 

 the surface. They are likewise enlarged at the hin- 

 der extremity, and rounded, particularly in the fe- 

 males.

Lampyris festiva, Donovan's Brit. Ins. xvi. pi. 544. 



The length of this insect is about three lines and 

 a half The colour is a tawny orange, with the apex 

 of the elytra, a spot on the middle of the thorax, and 

 the under side of the body and legs, brownish black. 

 Each elytron has four elevated lines, the spaces be- 

 tween which are deeply punctured. It is said by 

 Donovan to have been found in England, but is 

 considered a doubtful native.
