202 AMERICAN HYMENOPTERA. 



are yellow only iu their anterior aspects. The pleura mostly and the metathorax 

 where not maculated, black, as are the base of the second abdominal segment and 

 the inner aspects of anterior middle and posterior coxa?. The yellow maculation 

 on the scutellum forms two spots that leave a rather triangular brown area on 

 the posterior half of this segment. 



TFiwjfs.— Smoky brown, the infumation slight, excepting in the cells along the 

 anterior margin of the anterior wings. 



The apical segments of the abdomen largely brown. 



Type. — University of Kansas. 



Type locality. — Hamilton Co., Kansas. 



One female collected by S. J. Hunter. 



Cryptoebeilus pteneparcus n. sp. 



In structure almost exactly like parens from Cuba, which, how- 

 ever, has the first 3 abdominal segments entirely red. 



5. — 7 mm. long. — ifeat?.— Very closely and minutely punctured. Ocelli form- 

 ing an equilateral triangle. Distance between the posterior ocelli slightly less 

 than between the lateral ocellus and the nearest eye margin. Third joint of 

 the antennae a little longer than the first and second joints combined, and a little 

 longer than the fourth joint. The fourth and succeeding joints are subequal. 



Thorax. — Minutely roughened, apparently impunctate. The dorsum of thorax 

 mostly shining, excepting the metathorax, which is dull throughout. Pleura 

 dull, but not as dull as the metathorax. 



The wings are brownish, the brown intensified in the margins and second and 

 third submarginal cells. 



The basal uervure angulate, nearly as in the halictine bees. The transverse 

 median nervure inserted into the median as far from the junction of the basal 

 with the median as the transverse median is long. 



The third abscissa of the radius a little longer than the first abscissa thereof. 

 The second abscissa as long or nearly as the first and third combined. The sub- 

 costal nervure distinctly separated from the costal nervure so that a distinct 

 linear costal cell is visible. 



Stigma deep brown, as is the nervure bounding the anterior margin of the 

 wings. The other nervui-es are more of a brownish testaceous. 



Color. — Black. 



First and second abdominal segments entirely reddish castaneous. The base 

 of the third abdominal segment concolorous with the preceding. 



Type. — University of Kansas. 



One specimen, Douglas Co., 900 ft., Kansas 



One female collected by F. H. Snow. 



Anoplitis (Foinpiliniis) suowi n. sp. 



%. — 8 mm. — Black, with a slaty and whitish bloom, sericeous, with whitish 

 appressed pubescence that in certain lights hides the integument which is shin, 

 ing and apparently impunctate. 



Ocelli forming a low triangle, distance between the posterior ocelli distinctly
