A SPECIES OF MEGACHILE FROM BERMUDA 1 . 
By Theodore B. Mitchell 
A single female Megachile, captured during May, 1913, 
by Mr. Austin Brues in Bermuda, and sent to me by Dr. 
Bequaert for identification, proves to be either a variety of 
M. pruina Sm. or a very closely related species. Hence I 
will describe it here as a new variety of that species. If the 
male becomes available at some future time, it is possible 
that this will be shown to be specifically distinct from 
pruina. 
Megachile pruina bermudensis n.var. 
Size : Length 13 mm. ; breadth of abdomen 5 mm. ; an- 
terior wing 9 mm. 
Structure : Head broad ; eyes slightly converging below ; 
clypeus entire apically, the margin slightly thickened and 
shining medially; mandibles 4-dentate; cheeks as broad as 
eyes ; vertex flat, hind margin slightly concave ; lateral 
ocelli slightly nearer edge of vertex than to nearest eye; 
basal joint of flagellum longer than the second joint; hind 
metatarsi almost as long and as broad as the tibiae ; abdo- 
men cordate, the apical margins of the segments rather 
strongly depressed laterally, but not medially; segment six 
straight in profile, slightly concave at sides in dorsal aspect, 
with only suberect black hairs visible in profile, the ventral 
plate bare except for a marginal fringe of black hairs, the 
apical margin extending as a bare lip beyond the apical 
fringe. 
Puncturation : Close on cheeks and pleura, and on 
clypeus except in center; on the vertex close on either side 
of the median line, more sparse laterally; distinctly separ- 
iContribution from the Department of Zoology and Entomology, 
North Carolina State College, and published with the approval of the 
Director of the North Carolina Experiment Station as Paper No. 31 of 
the Journal Series.
