Records of Bees. 21 



Flab. Mackay, December 1899, at flowers of Cassia 

 {Turner), British Museum. 



Prosopis in fans, sp. n. (microjjhtnax, var. ?). 



$ . — Length 4 mm. or slightly over. 



Black, similar to P. microphenax, but face narrower ; 

 mesothorax more minutely punctured (not so rough) ; scutel- 

 lum with a large light central patch, postscutellum with a 

 small mark ; first r. n. joining first t.-c. as in microphenax 

 type (in microphenax var. a it enters base of second s.m.). 



This is perhaps only a variety of P. microphenax. 



Tlab. Mackay, Jan. 1900 {Turner). British Museum. 



Runs in the table to 52, where it is separated by its small 

 size. 



Prosopis constrictiformis, sp. n. 



$ . — Runs to P. constricta in table, and is only a little 

 over 4 mm. long, with the abdomen dark beyond the base of 

 the third segment. It is easily separated from constricta by 

 the much larger punctures of the mesothorax, and by the 

 character of the metathorax, which has the enclosure triangu- 

 lar and strongly ridged, and has no strong lateral keels. 

 The pleura has very large well-separated punctures, whereas 

 in constricta it appears minutely roughened. The antennas 

 are long ; the scape in front and the flagellum beneath bright 

 ferruginous. First r. n. entering extreme base of second s.m. 



Hab. Cooktown, Oct. 1902 {Turner). British Museum. 



Prosopis nigropersonata, sp. n. 



? . — Length about 7 mm. 



Robust, head and thorax black, abdomen dark steel-blue; 

 head without light markings; the thick upper margin of 

 prothorax, and the tubercles, bright orange, but the rest of 

 the thorax dark; legs black, with scanty short silvery hairs; 

 clypeus sericeous, sparsely and feebly punctured; flagellum 

 ferruginous beneath ; mesothorax and scutellum densely and 

 strongly punctured ; pleura strongly punctured ; area of 

 metathorax broad-triangular, shining, strongly irregularly 

 wrinkled ; sides of metathorax with short white pile ; tegular 

 black. Wings clear, nervures and stigma dark brown ; second 

 s.m. long, very much broader than high, receiving first r. n. 

 at its extreme basal corner; abdomen short, very finely 

 punctured. Runs in the table to 12, and runs out on account 

 of the medium size and black face. 



Bab. Mackay, March 1892 and Dec. 1900 (Turner, 854).
