Cryptocheilus austrinus, sp. nov. 



Type.— M. C. Z. 10,012. Texas. G. W. Belfrage. Coll. Pea- 

 body Academy Science, Salem. One specimen. 



9 Black; black antennae, yellowish wings darkened at tip, sparsely 

 hairy, clypeus truncate. Antennae slender, second and third fully 

 distance from eye to eye, eyes not reaching the vertex, latter convex, 

 ocelli close together, pronotum almost angulate behind, metanotum 

 coarsely transversely -RTinkled above on basal part, sparsely long 

 haired. All femora slender and smooth, the hind tibiae strongly 

 serrate, the inner spur hardly one third of the basitarsus. In the 

 hind ■wangs the cubitus is interstitial with fork of median; in fore 

 wings the marginal cell is slightly pointed, first recurrent ends at 

 apical fourth of the second submarginal, the second recurrent strongly 

 bent out near middle and ending before middle of the third submargi- 

 nal, the latter extending plainly beyond the marginal. Length, 20 mm. 

 Cryptocheilus austrinus has a great resemblance to C. texanus, but 

 the strongly wrinkled metanotum will distinguish it. 



Cryptocheilus inaequalis, sp. nov. 



Type.— M. C. Z. 10,013. Washington: Camp Umatilla, 27 June, 

 1882. Samuel Henshaw. One specimen. 



cf Similar to C. heiligbrodti. Black with reddish yellow wings, 

 slightly tipped with dark; as in male C. heiligbrodti there is a short 

 pale line on inner orbits opposite antennae. Entire body densely 

 black haired, front femur with short hairs below, and hind femur 

 rather hairy on the basal part above, and very few below; meta- 

 notum densely hairy, not wrinkled, with median groove, most dis- 

 tinct behind. Wings with venation similar to C. heiligbrodti; first 

 recurrent at middle of second submarginal cell; second recurrent 

 little curved, and meets third submarginal cell a little before middle; 

 the marginal cell is broad at tip, and the third submarginal reaches 

 a long way beyond it. Length, 17 mm. 



Mygnimia hesperina, sp. nov.
