lum is sliiuiug, very finely punctured in much the same way as the head. The 

 pleura are almost rugulose. The metathorax is rugulose to rugose ou the poste- 

 rior aspect, and ou the dorsal aspect has a triangular area which is acute and ex- 

 tends almost the entire length of this poition of the metathorax. The sculpture 

 within this area is not distinguishable from the sculptures adjoining this area. 



The color is black. The head is reddish castaueous, excepting a black band 

 extending from eye to eye across the vertex in the region of the ocelli, which 

 are surrounded by the black. 



The scape is largely blackish. The remainder of the antenna brownish and 

 testaceous. 



The prothorax, tubercles, the greater portion of the femora and tibise, and the 

 greater portion of the first and second segments of the abdomen are reddish cas- 

 taueous. The anterior tarsi are testaceous and the middle and posterior tarsi 

 daik brown. 



Type. — University of Kansas. 



Type locality. — Morton Co., Kansas, 3200 ft. 



One male collected by F. H. Snow. 



Trypoxyloii regiilaris n. sp. 



Related to apicalis ; the clypeus regular on the anterior margin 

 not at all produced. Metanotum with a rather short deep sulcis on 

 the superior surface. 



5. — ^eacZ and thorax 4 mm., abdomen missing. 



Face along the eye margin with the sculpture obscured by appressed silvery 

 pubescence, otherwise finely granular, with an indistinct median longitudinal 

 line extending from the anterior ocellus to between the insertion of the antenna; 

 where it becomes apparent as a shining raised line. Vertex and cheeks with the 

 sculpture more distinct and shining, with more or less distinguished fine close 

 punctures. 



Distance between the posterior ocelli nearly twice as great as that between 

 them and the nearest eye margin. The ocelli forming an equilateral triangle. 

 Joints of the antennae not well separated, the basal joints especially difficult to 

 distinguish from each other. Third antennal joint distinctly shorter than the 

 fourth, the succeeding joints subequal. 



Dorsulum dull granular. Pleura shining, with minute separated punctures. 

 Scutelluni more shining than the dorsulum, with fine close punctures. Metano- 

 tum shining, finely rugulose, with a longitudinal median rather broad sulcus ex- 

 tending almost the entire length of the sclerite. 



Wings transparent, brownish. Nervures and stigma very dark brown. The 

 clypeus obscured in the same way as the lower portion of the face at the eye 

 margin, otherwise the insect is thinly clothed with short whitish pubescence. 



Color almost entirely black. 



Type. — University of Kansas. 



Type locality, Douglas Co., Kansas, 900 ft.
