90 MAINE AGRICULTURAL EXPERIMENT STATION. I915. 



The slight commercial value of its food plant makes it of little eco- 

 nomic importance but where the willow is of value the species mtist be 

 counted plentiful enough to be detrimental to the tree. 



Pediopsis basalis Van Duzee. 



Pediopsis basalis Van Duzee. Am. Ent. Review, 1889, p. 171 ; Cat., 

 p. 260; Prov. Pet. Faune Ent. Can. 1890, 3 : 295. 



Known by the conspicuous dark brown basal marking of the clavus 

 which contrasts with the yellowish color of the other part. Length 5 

 mm. • 



Taken at Orono, 1913-1914 and at Highmoor Farm Aug. 15, 1913 on 

 poplar. Only a few specimens have been secured on any occasion and 

 the species is evidently one which occurs ordinarily in small numbers 

 and has little economic importance. 



Pediopsis hicolor n sp. 



A large black species greenish white below, of form of basalis but 

 very differently colored and showing no trace of the dark band on base 

 of elytra. Length 5.5 mm, width 1.5 mm. 



Head obtusely angled, the vertex narrow, pronotum roundingly angled 

 in front, the hind border concave, broadly angular at middle, rugae 

 coarse and rather short ; elytra long and narrow. 



Color smoky black above, the angles of the scutellum showing a more 

 intense coloring and the elytra near the tip with a faintly transparent 

 space noticeable in proper light. Below, face on upper half smoky 

 brown, shading to lighter at middle, but changing rather abruptly to 

 the dingj- greenish white of the lower half. Pectus, venter and legs 

 greenish white or, anteriorly, somewhat yellowish, the propleura with- 

 out black spot. Pygofer with a black spot each side a little behind 

 the middle. 



This species presents a very distinct aspect and while it might be 

 suspected of being a black form of some of the known species the 

 fact that it is so light colored below and the difficulty in connecting 

 it with any of the described species warrants a specific description. 

 Two specimens were taken from a broad leaf willow at Orono July 11, 

 1914.
