lowed to fit the metathorax; the segments slightly con- 

 stricted, the terminal segment transversely concave, and 

 its apex terminating in three slight angles ; the venter, 

 which is flat, is densely clothed from the second segment 

 with parallel layers of equal, moderately long, shining hair, 

 the segment being distinctly indicated by these layers. 



The MALE differs in being considerably larger; the 

 mandibles merely tridentate ; the legs longer and more 

 robust ; the tibice and tarsi more densely fimbriated 

 externally, and the tarsi relatively much longer ; the 

 abdomen densely edged laterally with short curled hair, 

 the terminal segment with three processes, the lateral

 shorter and straight, and the penultimate segment trans- 

 versely concave, with a strong tooth on each side curved 

 externally, and the venter glabrous beneath.

 How easy might it have been to regulate that flowers
