The antennae very much resemble those of Xylota: the 

 hypostoma is much more porrected, and is notched at the 

 extremity : the abdomen is short, broad, depressed, and nearly 

 naked, totally different from that of Xylota or Syritta : the 

 wings have the two transverse nervures near the centre per- 

 fectly straight, and the fourth subcostal nervure meets the 

 oblique submarginal nervure in an acute point at the apex 

 of the wing. 



Myol. luteola. AntenuEe bright yellow : head, thorax, and 

 abdomen nigro-seneous, the latter with a large yellow patch on 

 each side of the base : the wings are stained with saffron 

 colour along the costa, and have a dusky cloud half-way be- 

 tween the base and tip : the legs are black : the middle and 

 hind tarsi testaceous ; it is ^ of an inch in length, and ,^ of an 

 inch in the expansion of its wings.
