400 AMERICAN HYMENOPTERA. 



ment is castaneous, the apical dorsal segment is a practically triangular plate 

 that is distinctly though not strongly margined, and approximately one and one- 

 half times as long as wide at its base, its surface roughened, appearing closely, 

 indistinctly, longitudinally striate, on each side of the plate the tegument 

 is shining and somewhat more sparsely punctured than the front, this structure 

 is practically duplicated on the corresponding ventral segment, the punctuation 

 on the latter is. however, not nearly so distinct as on the former. 



Type. — University of Kansas. 



Type locality. — Oak Creek Canon, 20 miles southwest of Flag- 

 staff, Coconino Co., 6000 ft. elevation, Arizona. 

 Collected by F. H. Snow. 



Goryte!« papagoruni n. sp. 



Closely related to phaleratus, of which it may be a race. Ground 

 color black. 



J. — 11 mm. — Head. — Front smooth and shining, with a few small punctures, 

 clypeus with more numerous punctures than the front, but less distinct ; scape 

 as long or nearly as the pedicel together with the first joint of the flagel, the 

 latter distinctly longer than the next, but not as long as the second, plus half of 

 the third, pedicel and flagel mostly brown ; greater part of the basal half of the 

 mandibles, clypeus and face below antennse, a prolongation along the inner eye 

 margin and the greater part of the scape yellow. 



Thorax. — Rather dullish, though somewhat shining above ; mesosternum ante- 

 riorly distinctly carinated, the upper third of the mesopleura not separated from 

 the lower two-thirds, suture between the scutel and mesonotum not foveolate ; 

 wings strongly brownish in the marginal cells, elsewhere more of a yellowish- 

 brown, transparent, nervures brownish, stigma yellowish; pronotum, tubercles, 

 a margin along the mesonotum where it joins the tegulfe, a mark on each meso- 

 pleuron, posterior half of scutel, posterior two-thirds of the postscutel and a mark 

 on each side of the metathorax, yellow; anterior and middle tibiae in front and 

 all tarsi yellow ; tibiffi and claws mostly brown : tegulse brownish testaceous. 



Abdomen. — Greater part of first and of the succeeding segments yellow. 



% . — Essentially like the female. 



Types. — University of Kansas. 



Type locality. — Oak Creek Canon, 6000 ft., elevation, 20 miles 

 southwest of Flagstaff, Coconino Co., Arizona. 



Six specimens collected by F. H. Snow. 



Three $ paratopotypes differ from the type, apparently only in 

 color; in two of these specimens the second dorsal abdominal seg- 

 ment is quite brown, the one having nearly all of the basal two- 

 thirds and the other the basal half brown ; in the third 9 specimen 

 the metanotum has a yellow spot on each side ; the % paratopotype 

 has its antennse tipped with black.
