which is wider at l>:Lse and with an impression on the middle of each side. 

 Elytra with disli fetbly but evidently concave ; intervals each with two 

 rows of shallow punctures. Under surface and femora rather densely 

 clothed with yellowish scales. Lengtli 5-C mm. 



Southern half of State; frefjuent. February 21-December 10. 

 Both this and the next hibernate in eolonif s beneath mullein leaves 

 and half burieil loirs and chunks and in old trees in dry, upland 

 woods. Tliey occur in spring and summer on flowers, especially 

 those of the red haw {fratngus) and dogwood {f'ornus). One 

 speeiiuon at hand has the pygidium terminating in a sharp taper- 

 ing spine 3 mm. in length, and grooved its full length above and 

 beneath.

 Resembles the preceding but larger and usual- 

 ly dark piceous-brown in color. Thorax more coarse- 

 ly punctate, with fewer and larger teeth along the 

 sides, the median groove less distinct on basal half 

 and often with a short oblique ridge each side. 

 Teeth of front tibise broader, triangular and more 

 rounded or blunt at apex. Surface of elytra and 

 pygidium deiiusely granulate: under surface less 

 densely scaly. Length fl..j-T..o mm. (Fig. 422.)

 13-December 10. Occurs in the same places Rg. 422. x u- (Original.) 

 and often with canaliculatus. 



Series V PHYTOPHAGA. 



The members of this series have the tarsi apparently 4-.iointed, 

 rarely {SpondnUdu ), the fifth joint dLstinct. the three basal joints 

 almost always densely set with cushion-like pubesr^enee beneath; 

 third joint grooved on its upper surface or divided into two lobes, 

 so as to allow the insertion of the fourth joint near its base instead 

 of in front; head not forming a prolonged beak; labrum always 

 visible. About 3.5.000 species of Phytophaga are kno\^-n, almost all 

 of which, in the larval stage, are vegetable feeders, either devouring 

 the foliage or boring into the wood, stems, seeds or roots of plants. 

 Four families are n cognized by most authorities, all of which are 

 represented in the State. 



KEY TO FAMILIES OF PHYTOPHAGA.
