Several specimens taken in Lat. 54°. Taken also by Dr. Bigsby in 
Canada. 
Body brown, a little downy, not glossy. Mouth dirty-yellow ; pro- 
thorax transverse, impressed, reddish-yellow, with three black nearly 
confluent spots ; scutellum subquadrangular, truncated at the apex; elytra 
grossly but not thickly punctured ; suture and lateral margin paler than

|“ Found throughout the middle and northern parts of the Atlantic 
district.” Le Conte] 
[220.] 295. GALERUCA BILINEATA Æ%rby.—Length of body 2 lines. 
A single specimen taken in Lat. 54°. 
Nearly related to the preceding species, but smaller, the whole of the 
head is rufous, the joints of the antennae are shorter ; the prothorax is 
longer in proportion to its width ; and the elytra, nearer the suture than 
the lateral margin, have two somewhat elevated approximated blackish 
ridges, the interior one being the shortest and extending from near the 
middle to the base, and the other reaching neither base nor apex. 
[Considered by Le Conte as probably a specimen of G. notulata 
Fab., with indistinct markings. } 
296. GALERUCA MARGINELLA Æ%rby.—Length of body 3 lines. A 
single specimen taken in Lat. 65°. 
Body very black, a little downy. Mouth and base of the first joint of 
the antennae subtestaceous or reddish-yellow ; prothorax wider than long, 
impressed and confluently punctured on each side, with a longitudinal 
dorsal channel ; behind the margin bas a slight sinus ; reddish-yellow with 
three black spots, the intermediate one being the smallest ; elytra grossly 
and thickly punctured; lateral margin and apex reddish-yellow; legs 
dusky-yellow ; last ventral segment of the abdomen yellow and deeply 
emarginate. 
[Le Conte refers a specimen from Fort Simpson, Hudson’s Bay Terri. 
tory, to this species. |
