Bluish or bronzy metallic black ; antennae black ; tibiae and tarsi 

 fuscous or fuscous- black behind, dirty white in front. Clypeus incised ; 

 sixth joint of maxillary palpi double the length of fourth. Wings 

 hyaline. Costa and stigma fuscous-black ; below the stigma and extend- 

 ing to the cubital nervure is a fuscous cloud. Third cubital cellule a 

 little longer than second, of equal length throughout. Third transverse 

 cubital nervure curved. In the hind wings the recurrent nervure is 

 received in the middle of the cellule. The fourth joint of the maxillary 

 palpus is somewhat longer compared to the third and fifth than in 

 cceruleipennis, but the last is longer and thinner compared to the pre- 

 ceding. 



Length 5 6 lines. 



The coloration of the legs is variable, some speci- 

 mens having much more white on the tibiae, both before 

 and behind, than others, while on the other hand other 

 specimens have them quite black. Compared with 

 ciliaris, fuscipes is a larger and broader insect ; its head 

 is, if anything, more swollen, the incision in the clypeus 

 is deeper, and otherwise it is readily known from it by 

 the fascia under the stigma, as well as by the longer 

 third cubital cellule and sixth joint of maxillary palpi. 



H. violacea has usually been regarded as identical 

 with fuscipes, but Konow separates it as a distinct 

 species, it differing from fuscipes, according to Konow, 

 in the darker brownish wings, the clypeus not incised, 

 the legs blackish, with only the fore knees in front and 

 the hinder tibiae before the apex, on the upper side, 

 whitish ; fuscipes having the wings almost hyaline, the 

 clypeus distinctly incised, all the tibiae reddish brown,
