Fceiins nevadse n. sp. 



9. — Head black; face laterally silvery sericeous ; finely and sparingly piine- 

 tulate; mandibles subacute, rufous, tipped with black, punctate; clypeus sbort 

 and broad, sliallowly sinuate, broadly, not deeply emarginate; vertex almost 

 iinperceptly punctulate, running into minutely transverse striolse ; first segment 

 of flagellnm clavate; bead behind tbe eyes narrowed, so as to be subtriangnlar, 

 posterior eniargination narrow, the edge prominently subreflexed ; head under- 

 neath silvery sericeous. Neck short, transversely wrinkled. Thorax black ; sides 

 strongly silvery sericeous; protborax with a tooth on the lateral angles; thorax 

 entirely and closely covered with deep punctures, about half the size of the 

 ocelli, but not confluent ; propodeum coarsely reticulated. Wings hyaline, irri- 

 descent, without violaceous reflection ; veins dark. Four anterior legs and coxae 

 rufous; posterior black, except a small white band on the posterior tarsi near 

 base and on the posterior tibise near their base, dilated in front; posterior coxae 

 finely transverse-striolate. Abdomen red, except the extreme base and apex are 

 black; scarcely compressed, tip subtruncate. Borer red, sheaths black, tipped 

 with white. 



Described from five specimeus in the Cresson collection labelled in 

 Mr. Cresson's writing " nevadensis n. sp." The only variation 

 seems to be that one specimen has considerable fuscous on the abdo- 

 men. There is one specimen in the U. S. National museum collec- 

 tion that has the head behind the eyes a little less constricted. It is 

 doubtfully referred to this species. Tlie punctuation is a little more 

 obscure, the posterior tibiae rufous anterioi'ly. From New Mexico.
