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 intertropical 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.
