INSECTS OF BEULAH, NEW MEXICO. 59 



% Length 9.5 mm. — Quite similar to the female in appearance, sculpture and 

 wing structure, the central elevation of lahrum is not so pronounced. The dorsal 

 hairs paler, the punctuation of abdomenal segments coarser. 



Types. — Coll. Acad. Nat. Sciences, Phila. Type locality, Beulali, 

 X. M. One 9 , 1901 (H. Skinner). One 9 and one % , August 

 18 (T. D. A. Cockerel]). The female shows a relation to C ince- 

 qua.1%8. Also closely related to C. kincaidii Ckll., from which it 

 differs by the smaller size, different sculpture and black hairs of 

 dorsum. The male answers the description of C. wootoni Ckll., but 

 differs in the labrum, color of hair on dorsum, sculpture of post-scu- 

 tellum, and metathorax and size. 



C'olletes spurcus n. sp. Labium convex shining, space between eye and 

 base of mandible a little less than width of the latter at base, coxse apparently 

 without spine, prothoracic spines very short, pointed. 



9 Length 8 mm. — Clypeus shining, moderately coarsely punctured almost con- 

 fluently, sparsely pubescent. The rest of the head more or less punctured, dullish 

 except around ocelli where the surface is shining, face and back to occipital region 

 covered with pale brownish hair, the cheeks with almost white hair. Labrum 

 polished, with a small dent at base medially. Dorsulum with distinct close punc- 

 tures and a dull surface on anterior half, the posterior half more sparsely punc- 

 tured, almost impunctate on a median highly polished area. The dorsulum with 

 an abundant brown pubescence which is continued on the scutellum, the meta- 

 thorax and sides with pale pubescence. Superior disc of metathorax separated 

 from the posterior face by a ridge, the disc divided into narrow shining pits. 

 Funnel shaped enclosure defined, the broad part rugose and much like the sculp- 

 ture of the sides next the enclosure, the narrow part smooth and shining. Wings 

 brownish, uervuresand stigma almost black. Abdomen shining, finely punctured, 

 the segments excepting the apical one, with apical transverse bands of white ap- 

 pressed pubescence. 



% Length 7 mm. — Facial sculpture almost hidden by a heavy whitish pubes- 

 cence, clypeus with rather sparse, deep punctures. Surface above antenme and 

 on occiput closely, indistinctly punctured, dullish. Cheeks more shining in- 

 distinctly punctured. Dorsulum with distinct punctures on a shining surface, 

 sparse in the middle, closer near the margins, a fine longitudinal, median, im- 

 pressed line extending back from the anterior margin. Punctuation of meso- 

 pleurse more moderate than on the dorsum. The pubescence of thorax sparser 

 and darker on dorsum than that of face, on sides and beneath paler. Superior 

 disc of metathorax sharply defined by a transverse ridge, the space between with 

 a series of longitudinal narrow pits, their cavities polished. Posterior face of 

 metathorax with small triangular enclosure, with two short fovea? on its apical 

 middle defining a central elevation. The adjoining surface rather coarsely indis- 

 tinctly roughened. Wings clear, nervures and stigma very dark brown, first 

 recurrent nervure received by the second submarginal cells distinctly before the 

 middle. Basal segment of abdomen shining, with well separated fine punctures, 

 pilose much like thorax. The remainiug segments becoming more and more
