Antennae (9) with exserted hairs, in length scarcely equal to twice the 

 thickness of the segment where they occur: (S) segment II slender 

 on the basal half, distinctly thicker on the apical half than at middle, 

 or if not, then the length of exserted hairs not greater than the thick- 

 ness of the segment. .......... 8 



8. Calli margined or lined with black, rarely entirely black, ivory-white 



just before and extending inward from the anterior angles in one or 

 two curved lines upon disk of each callus; (5) segment II of an-

 serted hairs scarcely as great as the thickness of the segment 



pinicola n. sp. p. 162 

 Calli solid black; segment II very similar in both sexes, slender on the 

 basal half and gradually becoming thicker toward the apex, exserted

Tibiae uniformly dark, or pale on the apical half, sometimes with a

 Scutellum blackish, marked with pale at least on basal angles and at 

 apex ; hind tibiae dark, or an obscure pale band on apical half and 

 usually a pale indication just below knee . . . . . .11

 Legs and usually the body coloration dark reddish brown to blackish ;
