Psyche 
Megachile viridinitens n. sp. 
[June 
9. Length about or nearly 15 mm.; a parallel-sided 
black species, metathorax and base of abdomen densely 
covered with white hair, ventral scape entirely black, hair 
of legs black, wings dark fuscous except basally. The ap- 
pearance is exactly that of M. fumipennis Smith, and I had 
hastily assumed it to be identical until I noticed the follow- 
ing differences : middle of lower margin of clypeus with 
two little shining tubercles; hair of face entirely black; 
no white hair on prothorax (except fringing tubercles) 
and no converging lines of white hair on anterior part of 
mesothorax ; mesothorax finely punctured, the posterior 
middle minutely rugosopunctate ; abdominal segments 1 to 
4 strongly green, the callosities sublaterally shining, with 
sparse, strong punctures. Cairns, Queensland (W. M. 
Wheeler ) . 
Megachile chrysopyga Smith 
1 3,3 9, Sydney, N. S. W. ( Williams ) ; Melbourne ( H . 
Edivards ) . 
Megachile quinquelineata Cockerell 
Mr. F. X. Williams took females at Halifax, July 11-20; 
Cairns, April 1-12; Babinda, April 18; Mossman, April 24. 
Megachile ciliatipes Cockerell 
Mr. Williams took males at Halifax, July 11, and Ba- 
binda, April 16 and 18. It seems very likely that this is 
the male of M. quinquelineata, but I find that it is practi- 
cally identical with the male of Androgynella detersa 
(Ckll.). The female A. detersa has no ventral scape; it 
cannot be a mutant from M. quinquelineata directly, be- 
cause the last tergite is covered with pale hair, whereas in 
M. quinquelineata this is not the case. 
Megachile gilbertiella Cockerell 
1 9, Halifax, July 11-20 (Williams) . This specimen has 
the red of fifth tergite confined to the apical margin.
