much dilated at their apex and narrowed at the base. The 
THORAX longitudinal, nearly cubital in the ¢, and truncated at 
both extremities ;—in the ¢ the collay embraces the dorsolum 
and extends laterally to the origin of the wings, the tegule 
very large, the scutellum semicircular; in the ? an impression 
separates the collar from the mesothorax, which it embraces 
laterally; the superior mings of the g¢ with a nearly semicircular 
marginal cell and three submarginal cells, subequal, the second 
and third receiving each in their centre a recurrent nervure, the 
second being almost obsolete and the third transverso-cubital, 
having a pseudo-nervure springing from its centre extending half 
way to the apex of the wing; the legs moderately long in the 
$, somewhat robust and spinose in the 9. The aBDomEN 
ovate, the first segment subpyriform, the second subcampanu- 
late, and the apical segments much curved in the ¢. 
Type, M. Europea. 
+1+ This genus was first established by Linné; its ety- 
mology is uncertain, but it is conjectured to be derived from 
its supposed want of wings. Linné placed the male in the 
genus Apis.
