Flagellum slender, red beneath, very slightly widened at end ; face densely 

 covered with creamy-white hair; the very thick mandibles with a bright red 

 patch near apex ; anterior coxae with moderately long, strong spines, outer 

 half of coxa ferruginous; anterior trochanters strongly angulate below; ante- 

 rior femora mainly light reddish, more yellowish on inner face, with three 

 black lines, the apical half on outer side largely black; these femora are also 

 peculiarly formed, angulate beneath basally, then with the upper and lower 

 sides parallel, until toward the apex the lower side is provided with a low 

 keel ; anterior tibiae trigonal, red, with black on margins, the posterior outer 

 margin very broadly black, the anterior outer one only black on basal half; 

 anterior tarsi pale yellowish, greatly modified ; first joint boat-shaped, red 

 apically ; second with a large black spot at base, and the apex prolonged into 

 a finger-like process ; inner margin of boat-shaped process with thick black 

 hairs ; hair of posterior fringe white on outer side, black and white within ; 

 claws deeply bidentate ; middle and hind femora and tibiae black, marked with 

 red; middle tarsi cream-colored basally, light reddish apically; hind tarsi 

 mainly dark, but outer half of basitarsus cream-color; middle coxae with slen- 

 der black spines ; abdomen red with the fifth and sixth segments black, keel 

 of sixth segment very broadly emarginate ; no conspicuous apical (subventral) 

 armature. 



This is such a compHcated insect that a complete description of all 

 its peculiarities would fill pa.s^es. It differs from the male of M. 

 pulclira Sm. (to which it runs in Friese's table) by the mandibles 

 having only an apical red patch, the scape all black, flagellum black 

 above, and the keel of sixth segment of abdomen deeply emarginate. 



Megachile philinca Cockercll, variety a. 



Guayaquil, May-June, 1913 (Brucs). 



The two males collected differ from the types in having the pale 

 hair of thorax above white instead of fulvous, and the legs bright 

 red. In the original males of philinca the dingy color of the legs is 

 apparently due to immaturity, since the female has them bright 

 ferruginous.

This certainly appears to be Friese's species, but it is the sixth 

 segment of the abdomen that is bispinose; Friese says the seventh 

 segment, but probably by a slip of the pen, as he does not mention the 

 sixth at all.
