wards, and very shiny ; the basal area narrow, finely roughened, and 

 with very few (less than twenty), short ridges. Tegul?e brown. 

 Wings dusky hyaline, with a faint cloud toward the apex ; stigma and 

 nervures almost black. Femora shiny black; tibiae and tarsi brown, 

 and with ochraceous pubescence. Abdomen rather broad and blunt, 

 shiny throughout; discs of all the segments very finely punctured, their 

 apical margins impunctate but distinctly Hneolate; those of segments 2 

 and 3 appear a very little contracted, so that the rest of the segment 

 bulges slightly above the margin. Pubescence very scant, whitish be- 

 low and buffy above. 



Hah. Ouirig^iia, Guatemala, one ('=type) nearly 7 mm. Feb- 

 ruary 1912. (Mrs. W. P. Cockerell). 



This species is most closely related to H. zephyrns Sm. ; 

 from which its larg^er size, olive color, absence of testaceous 

 margins on the abdominal segments, and the almost black ner- 

 vures of the wings, easily distinguish it. 



Halictus cattellae sp. nov.

 mesonotum brassy, olive green ; abdomen very dark olive green, the 

 apical margins of the segments dark brown. Facial quadrangle about 

 square ; lateral margins of the clypeus free, the lower corners of the 

 eyes long; face opaque, finely and very closely punctured above the

 pleura coarsely punctured ; the upper half of the metapleura with 

 short irregular plicae crossing it at right angles; mesonotum opaque, 

 rather coarsely, and closely punctured, and finely and sharply rough- 

 ened, median and parapsidal grooves long but not deep. Basal area 

 of the metathorax narrow, its edge broadly rounded, slightly elevated 

 and indented at the middle, finely Hneolate, and with a few short, 

 simple plicae. Tegulae dark testaceous. Wings dusky, amber hyaline; 

 costal nervure reddish brown, stigma and other nervures dusky honey

 esl at the second segment; very shiny throughout, punctures very fine 

 and widely scattered on the discs of all the segments, even less dis- 

 tinct on the first; the dark brown apical margin of each segment al-
