 ing July, August, and September, 1909, by Messrs. Crawford and McConnell. 



Colletes recurvata n. sp. 



Female; — Black. Length 11 mm. Head a trifle broader than long. 

 Face clothed with rather short, white, or pale yellowish, pubescence, mixed 

 with black on vertex. Eyes converging at base. Clypeus nearly nude, convex, 

 depressed in a median groove ; covered with long shallow punctures, forming 

 longitudinal stride ; truncate at end. Supra-clypeal area sparsely punctured. 

 Malar space very short, not over one-sixth as long as broad. Vertex quite 

 closely punctured with punctures of two sizes, differing from even puncturation 

 of face. AntemiK short, black ; scape slightly punctured. 



Thorax — Covered in front and on sides with short, dark ochraceous hairs, 

 sometimes thickly, but more often sparsely mixed with black on mesothorax, 

 and sides of scutellum. Mesothorax covered with large round punctures, quite 

 close together in front, becoming more sparse as they approach the rather 

 large, almost impunctate disk. Scutellum with large, sparse punctures over 

 entire surface. Postscutellum thickly covered with large shallow punctures, 

 giving a rugose appearance. Metathorax covered with long, dense, pale yel- 

 lowish pubescence on sides, noticeably lighter, and finer than that of scutel- 

 lum. Superior face of metathorax normal, with the usual dozen or more 

 shining pits ; posterior face with enclosure funnel shaped, shining, and smooth 

 except for a few transverse ridges, which are not very noticeable. Enclosure 

 broad, only l-l^A times as long as wide at top. Lateral faces with very 

 large, shallow, rectangular, pit-like punctures, forming rugse. Mesopleura 

 densely punctured, with large round punctures ; clothed with rather sparse 

 ochraceous pubescence, becoming white underneath. 



Abdomen — Rather long, convex, suboval, rather pointed at apex. Apical 

 margins of segments with fascise of short, sparse, white hair. A few longer 

 black hairs on last two or three segments, often with ferraginous on venter. 

 All segments thickly and finely punctured ; these punctures on first segment 

 a little larger and slightly more scattered than on others. Apex of first 

 segment depressed. 



Wing.s — Sub-hyaline, nervures almost black, stigma same. Tegulce very 

 dark, not noticeably punctured. 



Legs — Entirely dark ; posterior femora clothed with long, silky, golden 

 pulse.scence ; tiba: with shorter, lighter, denser pubescence. Tibial spurs golden 

 brown, not pectinate, but microscopically ciliate. First tarsal joint about three 

 times as long as wide (Fig. 72 D.), much golden hair on inner side. Apical 

 tufts of all tarsi golden. Claws reddish, medially toothed. 



Maf-K — General appearance similar to female, but a little smaller, more 

 slender, more densely haired, and with an abundance of white hair on under 

 parts of head, and lower sides of thorax. 



Head — Densely clothed with long pubescence on face. No lilack hair on 

 vertex. The change from strong, close punctures of face to the mixed 

 punctures of vertex very abru[)t. Antenn.x longer than in female, but still
