In Sclirottlcy's kej^ it runs exactly to M. chamacoco^ 

 Sclirott., which it resembles in the hook-like \ spine on 

 middle tibia, but otherwise it is very distinct. In YachaFs 

 table it falls in the vicinity oi M. rectipalma^ Vach., but is 

 not very similar. In Friese^s table it falls nearest M. lobi- 

 iarsis, Bm., a quite different species. There is a general 

 resemblance to 31. aricensis^ Friese, which has a very large 

 hook-like process at end of middle tibia ; but the head and 

 thorax of aricensis are covered with fulvous hair dorsally, 

 and there are many other differences. 



Megachile melanopoda^ sp. n. 



^ . — Length about 8*5 mm., anterior wing 6 mm. 



Black, the abdomen rather narrow but parallel-sided ; 

 mandibles black with a red subapical mark ; antennse black; 

 tegulse rather dark red. Wings dusky, the marginal cell 

 and apical field dark fuliginous, shining purple ; nervures 

 black ; femora and tibiae bright red^ tarsi black. Head 

 broadj orbits converging below ; face and front densely 

 covered with pale golden hair ; cheeks with white hair ; 

 vertex with sparse long black hair; antennee simple at end, 

 not enlarged or flattened; mesothorax and scutellum shining, 

 with strong rather close punctures, and beset with long 

 black hair ; a slender band of light hair in scutello-meso- 

 thoracic suture ; a small patch of light hair above each 

 wing-base ; prothorax, pleura, and metathorax with white 

 hair; first recurrent nervure joining second submarginal cell 

 very near its base ; anterior coxse broad and lens-like^ 

 shining, not spined; anterior tarsi simple. Abdomen 

 shining, with conspicuous white hair-bands or patches at 

 sides of segments, but lacking in middle ; there is, however, 

 light hair in the basal sulci ; disc of fifth segment with erect 

 black hair, and a very small amount (hardly visible) of pale; 

 sixth segment not conspicuously hairy, the weak keel entire, 

 a little depressed in middle ; venter black, with three very 

 conspicuous pure white hair-bauds.

In Schrottky's table it runs exactly to M.giraffa^ Schrott., 

 differing by the black apex and venter of abdomen, and the 

 simple apex of antennse. Also related to M. orba^ Schrott. 

 The nearest relatives, however, are M. exaltata, Smith 

 {incongruay Smith), and M. lamnula^ Vachal, both Brazilian. 

 The fringe of the anterior basitarsus is white, not black as 

 in lamnula^ nor are the fifth and sixth abdominal segments
