Female. Exp. al. 1 poll., long. corp. 6 lin. 



Head, thorax, and first two pairs of legs rufo-testaceous ; first 

 two joints of antennae of the same colour, the second brownish 

 above; third joint of antennae, abdomen, hind tibiae above, and four 

 last joints of hind tarsi blue-black ; hind femora, base of tibiae, and 

 first joint of tarsi ochraceous. Fore wings hyaline, with the base, a 

 band across the centre, and the extremity of the third submarginal 

 cell smoky brown, with a violaceous shade : hind wings smoky 

 hyaline, with a violaceous shade, and more or less clear before the 

 apex. 



Judging from the analogy of the sexes in Ptenus serratus, I have 

 no doubt that the insect with transparent wings which Curtis 

 figures as the male really is so. None of our four female specimens 

 have more than three submarginal cells.
