Halictus asperitlwrax, sp. n. 



? . — Length about 8 mm. 



Black, hair of head and thorax white below, dull pale 

 ocbraceous above. A species related to H. chapmani, but 

 easily separated by the dull coarsely rugoso-punctate meso- 

 thorax. Mandibles dark, reddish subapically, and with 

 shining golden hairs ; clypeus broad, not produced, shining, 

 with grooves and a few scattered punctures ; front broad, 

 appearing minutely granular, but microscopically longitu- 

 dinally striate, with rows of punctures separated by raised 

 lines ; flagellum dull brown beneath ; mesothorax coarsely 

 granular, with very dense punctures ; scutellum more shining 

 and much more finely punctured ; area of metathorax broad, 

 very finely lineolate all over ; posterior truncation large and 

 very well defined ; the scutellum has a few very large punc- 

 tures scattered among the small ones ; tegulse shining rufous, 

 not punctured. Wings faintly dusky, stigma and nervures 

 dilute sepia; third t.-c. and second r. n. greatly weakened; 

 second s.m. very large and broad, receiving first r. n. nearly 

 at its end. Legs very dark reddish, with pale hair, yellowish 

 on inner side of tarsi ; hind spur with a broad but not long 

 subbasal truncate tooth, and obscure crenulatiform teeth 

 beyond (II. lanarius type of spur) ; abdomen broad, with an 

 evident dark reddish tint, granular from minute punctures, 

 with broad dull white basal hair-bands, that on second 

 segment failing in middle. In my table in ' Entomologist/ 

 Nov. 1905, this runs straight to H, gilesi, which it much 

 resembles, differing in the microscopic characters. The 

 second abdominal segment is minutely and nearly uniformly 

 punctured all over, the punctures running more or less into 

 grooves near the posterior margin ; in gilesi the puncturation 

 is more diversified, but in both the transverse lineolation can 

 be seen. The front is also different.

Parasphecodes plorator, sp. n. 



$ . — Length about 10 mm. 



Easily known from all the other species by the entirely 

 black head, thorax, and abdomen, with scanty pale pubes- 

 cence, the dark reddish legs, and the very dark smoky wings. 

 Mandibles dark ; lower edge of clypeus with long golden 

 hairs; clypeus shining, with irregular punctures; front 

 appearing granular, microscopically lineolate and pleated,
