of mandibles apparently less than half the width of the latter at base. Protho- 

 racic spines rudimentary. 



9 Length 10 mm. — Front with coarse, closely arranged punctures, on vertex 

 they are much finer and sparse. Cheeks indistinctly punctured, shining like 

 rest of the head. Clypeus with coarse, large elongated punctures creating a 

 longitudinal appearance. Dorsulum with deep, large punctures, as closely 

 arranged as possible on the anterior half which is dull. On the posterior half the 

 punctures are scattered on a polished area. Scutellum punctured much like 

 anterior half of dorsulum, sculpture of postscutellum hidden by the pubescence. 

 Mesopleurse shining, with close deep punctures. Superior disc of metathorax 

 bounded by distinct ridge. The longitudinal divisions defined by strong ridges 

 the spaces longer than wide, polished. The enclosure funnel shape with a broad 

 neck, smooth and shining. The rest of metathorax roughened suhopaque. Pubes- 

 cence, of face, cheeks, pleurae, legs, to the tarsi and basal segment of abdomen pale, 

 grayish. Head and thorax dorsally rather thickly covered with a dull pubescence, 

 tinged with ochreous. Wings clear, nervines dark brown, costal, subcostal and 

 stigma almost black. First recurrent nervine received by the. second submarginal 

 cell at the middle. First abdominal with fine well separated punctures on a 

 smooth shining surface, on the second segment the surface is the same as on the 

 preceeding, the punctures closer, the rest of the segments duller, having no dis- 

 tinct punctuation. Apex of abdomen with brownish hairs. 



Black. Claws very dark brown. 



Type. — Coll. Acad. Nat. Sciences, Phila. Type locality, Beulah, 

 N. M., August 25, 1899 (W. P. Cockerell). * Paratope!— End of

 second and third abdominal segments. One is 8 mm. long and has 

 the labrum dull instead of shining. 



Colletes paniscus n. sp. Antennas thickened, the third joint almost 

 twice as broad at apex as at base, longer than tlie fourth. Labium convex 

 polished with no impression medially. Sides of posterior face of metathorax 

 finely roughened. In appearance much like spurcus. 



% Length 8 mm. — Anterior margin of clypeus slightly curved in, the surface 

 almost hidden by the long whitish pubescence, punctured rather coarsely, trans- 

 versely impressed near the apical margin. Space between eye and base of man- 

 dibles a little less than the length of the fourth autennal joint. Front and top 

 of head with rather closely arranged small strong punctures. Checks roughened. 

 Punctures of dorsulum strong more separated on the disc than near the margins, 

 but not so widely as usual. The surface rather shining. Mesopleurse shining, 

 the punctures thereon close together, shallow. The superior transverse area of 

 metathorax indistinctly divided, the striye irregular. Enclosure of posterior face 

 funnel shaped, the neck broad, polished, above the area is closely regulose. Thorax 

 covered with whitish pubescence, the enclosure of metathorax bare, pubescence
