6. Head black, pale color appearing along the median line of front ; femora 



and ventral surface piceous, shining, tibiae biannulate with pale; slen-

ew species 



About the size of hrcvis or nubilus, dorsum glabrous, rather coarsely punc- 

 tate, shining, second antenna! segment longer than the head and pronotum 

 taken together ; femora black, only the apices pale, dorsum pallid grayish- 

 testaceous and marked with black, much darker in the male. 



$. Length 4.7 mm. Head: width .98 mm., vertex .38 mm., length .48 

 mm. ; carina delimited behind by a groove, sloping anteriorly to a pair of curved 

 impressions on vertex, collum broadly exposed, vertex broader than the dorsal 

 width of an eye; black, carina, spot each side of vertex and curving along 

 front margin of eye, usually interrupted and leaving a spot just above base 

 of antenna, and the juga, pale. Rostrum, length 1.84 mm., black, attaining the 

 middle of hind coxae, first segment extending upon basal one-third of xyphus. 



Antennae: segment I, length .34 mm.; II, 1.71 mm., nearly cylindrical, 

 equal to segment I in thickness, pubescence pale and blackish mixed, a few 

 black exserted hairs which in length are not equal to thickness of segment ; 

 III, 27 mm. ; IV, .27 mm. ; black, the last two segments slender and beset 

 with several blackish exserted hairs which in length exceed the thickness 

 of the segments. 



Pronotum: length 1.08 mm., width at base 1.8 mm., anterior angles .74 

 mm., collar .65 mm. ; disk convex, coarsely and rather irregularly punctate, lateral 

 margins distinct, nearly straight, narrowed in front, the anterior angles little 

 wider than the collar ; calli black, shining, convex and confluent, delimited be- 

 hind by coarse punctures, disk of each callus with three or four fine punctures 

 near the latero-posterior angles ; disk olivaceo-testaceous, basal angles broadly 

 black, becoming black along the basal margin and irregularly among the punc- 

 tures either side of the median line, frequently leaving a paler ray behind 

 lateral angle of each callus, collar pale ; propleura black, ventral and posterior 

 margins more or less pale ; xyphus black, moderately convex, collar pale.
