350 T. D. A. COCKERELL. 



Halictus farinosu* Sm. 9 (T.). 



A large banded species; belongs to Robertson's Halictus s. str., 

 and runs out of his table because legs are not ferruginous, except 

 middle and hind tarsi, and small joints of anterior tarsi, and the 

 hind spur is finely serrate. Stigma and nervures ferruginous; 

 wings with a decided though not strong reddish tint; third s m. 

 very broad ; the four dull (yellowish or greyish) white abdominal 

 hair bands are very broad and distinct, the region between the 

 bands is dull, because pubescent; mesothorax closely and strongly 

 punctured; clypeus shining, with quite widely separated punctures; 

 base of metathorax minutely rugose ; tegulse large, with a testaceous 

 spot broadly surrounded by dark brown. 



Halictus pectoralis Sm. 9 (T.;. 



Florida. Runs to pector a lis in Robertson's table. Area shining, 

 with large irregular wrinkles ; hind spur with six teeth, the basal 

 ones very large ; stigma rather dark reddish-brown ; second and 

 third abd. segments with lateral subtriangular patches of whitish 

 pubescence. Compared with H. pectoraloides, it is a broader, more 

 robust insect, with the area much more coarsely wrinkled, and 

 lunate rather than hemispherical in outline, much shorter than 

 semicircular in an anteroposterior direction ; the mesothorax also is 

 much duller and more punctured. 



Halictus confusus Sm. 9 (T). 



Wings very yellow; stigma very pale honey color; third s. m. 

 very large, fully twice as large as second, but its outer margin with- 

 out a distinct double curve ; outer veins not perceptibly weaker 

 than inner; b. n. with the bend very strong; hind spur of the 

 serrate type, but the teeth rather long; head and thorax dark blue- 

 green ; clypeus black, supraclypeal area brassy ; abdomen without 

 hair bands, hind margins of segments testaceous; cheeks normal; 

 tegulse testaceous, with a piceous cloud. The first abd. s. seems to 

 have a barely perceptible greenish lustre. Goes to Halictus s. str. 

 in Robertson's tables. The above notes are from the type ; the series 

 consists of two species mixed. 



Halictus iinitatus Sm. i (T.). 



Very small ; head and metathorax very dark green ; mesothorax 

 and scutellum with some purple reflections, but they seem to be a 

 stain, produced artificially in some way ; the abdomen might fairly
