THE CANADIAN ENTOMOLOGIST. 97 



[Belongs to Le Conte's genus Trichabda. " A common species 

 extending from Lake Superior and the Mississippi Valley to the Pacific." 

 Le Conte.] 



294. Galeruca Sagittarius Gyll. — Length of body 2^ lines. 

 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 j scutellum subquadrangular, truncated at the apex ; elytra 

 grossly but not thickly punctured ; suture and lateral margin paler than 

 the rest of the elytrum ; anus and legs reddish-yellow ; tarsi darker. 



Variety B. With the base of the antennae yellowish underneath, the 

 black spots on the prothorax distinct, and the elytra entirely of a brown- 

 ish yellow. 



[" Found throughout the middle and northern parts of the Atlantic 

 district." Le Conte.] 



[220.] 295. Galeruca bilineata Kirby. — 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 Kirby. — 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 has 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 TerrL 

 tory, to this species.]
