Pseudoponurgus cethiops (Cressoii). 



Berkeley (near Denver), Colorado {Oslar). In Coll.

Halictus clelandi, sp. n. 



cJ . — Length about 6 mm. 



Head and thorax black, abdomen and legs dark reddi-sh 

 brown ; pubescence greyish white, rather abundant ; lower 

 part of cly))eus cream-colour, the actual margin ferruginous ; 

 mandibles ferruginous, dark at base ; flagellum long, crenu- 

 late, dark coffee-brown beneath. 



This cannot be the male of H. globosus, as the thorax has 

 no seneous tinge, and the second r. n. and third t.-c. are very 

 distinct {H. cognatus, Sni., is probably the male of globosus). 

 The much darker flagellum easily distinguishes it from 

 H. oxleyi. Head broad, eyes converging below, face with 

 much light hair; front minutely, very densely punctured, a 

 very small space in front of ocellus smooth and shining ; 

 mesothorax hairy, finely and densely punctured, but shining; 

 area of metathorax semilunar, with fine irregular rugte 

 extending over the whole surface; pleura shiin'ng ; tegulae 

 rather large, smooth, pale reddish testaceous. Wings ample, 

 liyaliiie, nervures and stigma pale testaceous ; second s.m. 

 receiving first r. n. before the end ; third s.m. very n)uch
