There are in the collection a male and a female specimen of 

 this species. They agree well enough with Walker's description. 

 They have the two black spots on the mesonotum as described for 

 P. bipunctata, Brauer, but not mentioned in the original description 

 of nigricornis. I add complete figures of the venation and of the 

 genitalia. 



[One of these specimens is from Cachar, Assam. — N. A.]
