49. MicPOdon Meig. 



Species of medium size and of a somewhat broad and clumsy 

 shape ; the colour is dark æneous with more or less distinct abdominal 

 bands of pale hairs. (This description refers only to the European 

 species; foreign species may be large, and sometimes of quite another 

 shape, wasp-like with a petiolate abdomen, and they may be of 

 various, sometimes brillant colours). Head semiglobular, a little broader 

 than high, about of the breadth of thorax; it is a little excavated 

 behind. Eyes separated in both sexes, the most broadly in the female; 

 in the male the frons is narrowing downwards to somewhat above 

 the antennæ and then widening down to the epistoma, the inner eye- 

 margin thus angular; in the female the horders are almost parallel 

 or slightly diverging downwards, not or almost not angular. The eyes 

 are bare ; the facets not, or practically not, enlarged above. Frons not 

 prominent, hairy, but with a bare space above the antennæ. The antennæ 

 are inserted above the middle of the head, very near to each other, 

 and there is no lunula visible above them; they are elongated and 

 porrected, with linear joints; the basal joint is about as long as the 

 two other joints together, the second joint the shortest, the third 

 linear with the arista near the base; the arista is short; the basal 

 antennal joints have small hairs, the third joint and arista micro-
