Halictus thoracicus merescens Cockerell. 
Halictus megregori Cockerell. 
Nomia thoracica stantoni (Ashmead). 
Fourteen specimens. 
Nomia longitarsis Cockerell. 
One female. The specimen has opaque pale yellowish bands 
on abdominal segments 1 to 4, and the stigma ferruginous. It 
thus differs both from the type and variety eboris, and possibly 
represents a distinct race. 
Nomia levicauda Cockerell. 
Two females. 
Nomia quadrifasciata Ashmead. 
Five males and twenty-seven females. Three of the five males 
are typical N. quadrifasciata; the other two have more dusky 
hind legs and approach var. notha (Cockerell). It is certain 
that notha is only a variation of N. quadrifasciata. 
Nomia iridescens Smith. 
One female. On Melastoma polyanthum Blume, May 27. 
Nomia strigata (Fabricius) var. ridleyi Cockerell. 
One female. 
Nomia megregori sp. nov.

robust (anterior wing, 8 millimeters; width of thorax, about 4 
millimeters) ; the blue-green bands on hind margins of abdom- 
inal segments 2 to 4 very narrow (hardly or not half as wide as 
In quadrifasciata) ; lobes of postscutellar process large, broad and 
obtuse ; tegulz entirely black; prothorax and tubercles with black 
hair, but conspicuously fringed with white tomentum ; mesothorax

punctures dull; hind tibisee with much black hair posteriorly: 
middle tibie beneath, and thei pase, with 
shining ved eae eir femora beneath at ba 
Soy female. By the form of the postscutellar process related 
- incerta Gribodo, from Java, but the mesothorax is differen".
