280 THE CANADIAN ENTOMOLOGIST. 



Head relatively smaller, the front similar, the basal antennal joint 

 much more slender, not quite as wide as the second and less than 

 half as thick as the eleventh, its upper surface smooth and almost 

 glabrous ; eyes larger 5 



5. Head almost twice as wide as long, the eyes unusually large, convex and 



prominent, at barely their own length from the base; surface smooth 

 and polished medially, finely, sparsely granose laterally ; prothorax 

 nearly as in richer^ but more finely and sparsely granose basally and 

 apically ; elytra larger, not quite so abbreviated, shining, the discal 

 impression strong and broad basally, but with its internal part 

 prolonged posteriorly, becoming obsolete only behind the middle ; 

 abdomen about as long as the elytra and nearly as wide, rounded at 

 the sides, the basal impression almost similar, ^[ale with the last 

 ventral large, nearly as long medially as the three preceding com- 

 bined, gradually strongly and broadly impressed toward apex, the hind 

 margin thin and sublaminate. Length, 1.5 mm.; width, 0.52 mm.

fej'rugineus, n. sp. 



Head evidently not twice as wide as long, the eyes well developed, but 

 less prominent, and at rather more than their own length from the 

 base ; body much smaller in size and more yellowish in colour ; 

 prothorax nearly as m/errugineus, but more convex and with a less 

 evident sinus at each side near the base ; elytra smaller and rather 

 more abbreviated, about as long as the head and prothorax, and 

 fully a third wider than the former, impressed nearly as in the 

 preceding, except that the median groove extends only to the middle; 

 abdomen fully as wide as the elytra but not quite so long, the basal 

 impression not quite so extended transversely as in fen'icg'meus. 

 Male with the last ventral very much shorter and more transverse, 

 with a rather smaller and more definite transversely oval apical 

 impression. Length, 1.3 mm.; width, 0.42 mm. Pennsylvania

6. Form rather stout, convex, shining, testaceous ; head well developed, 



thick, convex, transverse, deeply sinuate at base as usual, granulose 

 except between the three fovete, the apical transversely oval and 

 deep, the frontal margin thick, depressed ; eyes moderately small, 

 prominent, at a little more than their own length from the 

 base ; first antennal joinc as long as the funicle, rather thicker
