characters arc made use of as ser\e to distinguish genera in allied families, 

 most of die si)ecies would become generic types. The closed sub- 

 marginal and se(.:ond posterior cells in this species ha\e induced Bigot to 

 make it the ty[je of a new genus, but the same reasons would recjuire new 

 generic names ft)r //. brcvirostris and the species of RhyuchocepJialiis 

 described below. For the present, therefore, 1 believe it will be better to 

 hold Parasyinniictiis in abeyance.

Belongs in the division with closed second posterior cell, to which R. 

 Tausc/icri Fischer, the t)i)e, ])ertains. A male specimen from Washington 

 Territory, since received, has the i^roboscis considerably shorter, the eyes 

 nearly contiguous near the ocelli, ocelli with a conspicuous ttift of black 

 pile and the style of the antenna very indistinctly jointed, even under a 

 compound lens.
