Black ; the head red, the base of antennae broadly and legs reddish 

 yellow; the antennas a little longer than the body, fuscous, fuscous- 

 testaceous in the $, which has the fourth and fifth joints curved. 

 Radial cellule elongated, large ; the second abscissa of radius is curved, 

 and more than twice the length of the first. The fringe on the wings 

 is close and longish ; the pubescence on the median segment and base 

 of abdomen moderate.

Sometimes the thorax becomes piceous. 

 In this species the radial cellule is longer than in

Black; the thorax in one or two specimens inclining slightly to 

 fuscous; the head red, the vertex castaneous; the antennae and legs 

 clear yellow, the former slightly infuscated towards the apex ; the base 

 of the abdomen red ; wings clear hyaline, the nervures pale testaceous. 

 Scutellum, median segment, and base of abdomen rather densely covered 

 with long pale hair. Antennas longer than the body, stout, the basal 

 two joints subequal, the third a little longer ; the fourth and fifth 

 longer than the others, distinctly sinuated ; the last joint not longer 

 than the penultimate. Radial cellule of medium size, twice longer than 

 broad ; the second abscissa of the radius fully one-half longer than the 

 second, which is twice the length of the first ; $ cubitus a mere stump ; 

 the spurious vein traced to the middle of the wing. $. 



Length 1 mm. 



This is a larger species than basimacula, the antennse 

 are of a paler and clearer yellow and not dark fuscous ;
