 impressed linelet also black. 



PLATE VII, FIG, 9. 

 Length of the body 2J — 3 lines. 



A single specimen taken in Lat. 65°. Taken also by Professor Feck in New 

 England ? 



DESCRIPTION. 



Body subovate, very black, underneath glossy. Head irregularly punctured behind : antennas 

 underneath piceous at the base : prothorax very minutely and lightly punctured, pale-yellow with two 

 black round dots in the disk between which above the scutellum is a less black triangular impression : 

 elytra very minutely and lightly punctured : forebreast pale-yellow. 



Variety B. Elytra with a blue tint.

(292) 1. Galleruca Olivieri. Olivier s Galleruca. 



Altica quadrimaculata. Oliv. Ent. v, 93, 673, 6, t. i, / G. 

 Length of the body 3j lines. 



Taken in Canada by Dr. Bigsby. 



DESCRIPTION. 



Very near related to Galleruca quadrimaculata F. Body long, glossy, reddish-yellow : posterior 

 part of the head black, a cross impressed between the eyes ; antenna? dusky with the four first joints 

 rufescent : prothorax impunctured, transversely subimpressed behind, sides margined : elytra very 

 minutely and lightly punctured with punctures just visible under a good lens ; at the base of each 

 elytrum nearest the suture is a roundish black spot, and another large oblong one extends from above 

 the middle towards the apex : posterior thighs a little incrassated ; tarsi dusky especially at the apex; 

 medipectus and postpectus black. 



This species forms a link between the Halticidce and Gallerucidce : it is clearly the Altica qua- 

 drimaculata of Olivier, and may be regarded as the American representative of Galleruca quadri- 

 maculata F. from which it differs principally in the colour of its antennae and its incrassated 

 posterior thighs.
