Blue-black ; thorax, scutellum, pleura, and sides of pectus luteous. 

 Wings smoky hyaline, the second recurrent nervure received at 

 the division between the second and third submarginal cells, in the 

 former of which stands a black dot. 



But for the neuration, which resembles that of the genus Scobina, 

 I should have considered this insect to be identical with H. calcanea. 

 The black pectus and legs render it impossible to confound it with 

 H. americana.
