middle flattened, smooth, and polished; antennae entirely black; 

 mesothorax dullish anteriorly, the posterior disk shining and punc- 

 tured; anterior part of scutellum impunctate, but only moderately 

 shining; tegulae clear ferruginous; wings hyaline, orange-tinted, the 

 apical margin pale grayish ; stigma and nervures ferruginous ; spurs 

 ferruginous; hind basitarsi broad. 



Piches and Perene Valleys, Peru, 2,000-3,000 feet altitude (Soc. 

 Geog. de Lima). This looks sufficiently like M. -fiabellata Vachal to 

 raise the question whether it could be its female, but it is quite dis- 

 tinct by the shape of the marginal cell and other characters. In 

 Schrottky's table of Brazilian Megachile this runs to M. gracilis^ 

 an entirely different insect with ferruginous legs.

MEGACHILE LAQUEATA, new species. 



Female. — Length about 11 mm., anterior wing 7.5 ; rather narrow 

 and parallel-sided, black, the general effect of the scanty pubescence 

 gray. Face, cheeks, and front with long clear white hair, clypeus 

 with long black hair; vertex with scanty black hair; thorax with 

 white hair, but disks of mesothorax and scutellum with scanty black 

 hair, not easily observed; j)osition of tubercles marked by a dense 

 tuft of white hair; legs with white hair, clear ferruginous on inner 

 side of tarsi; abdomen basally with thin dull white hair, apically 

 with rather coarse black hair, first segment with a small patch of 

 white hair on each side; segments 2 to 4 with narrow entire white 

 hair-bands, the last tinged with ochreous; sixth segment with ap- 

 pressed pale and erect black hair ; ventral scopa white, suffused with 

 ochreous on fifth segment and base of sixth, but on sixth, except base, 

 black. Mandibles broad, the two apical teeth prominent, marked at 

 sides with ochreous hair, and also a line of ochreous hair parallel 

 with broad cutting edge; clypeus short, densely rugosopimctate, the 

 lower margin crenulate; flagellum very faintly reddish beneath; 

 front and vertex minutely and closely punctured; mesothorax and 

 scutellum dull, with small indistinct punctures; tegulae very dark 

 brown; wings dusky, darker in region of marginal cell and apex; 

 abdomen shining; spurs pale ferruginous; hind basitarsi not very 

 broad. 



Ecuador, from the C. F. Baker collection. Very like M. peruviana 

 Smith, to which it runs best in Friese's table of species of Brazilian 

 subregion ; but if we may trust Smith's description it differs by the 

 darker wings and scopa black at end. Among the species Imown 

 from Ecuador, it is suggestive of M. philinca Cockerell; but that 

 differs from M. laqueata by the conical abdomen, red legs, bright 

 buffy hair surrounding mesothorax, red tegulae, etc.
