Szepligetti (l. c.) states: — " §. Length 25-30 mm.; terebra 

 35-50 mm.; sheaths white-banded before apex; posterior margin

Hemistephanus maculipennis. 



"Var. 1. 5- Hind tibiae entirely black. La Merced, Brazil. 



" Yar. 2. 5 d . Median segment transrugose. centrally punc- 

 tate. Wings pale brown to hyaline, centrally dark marked. Only 

 basal half of front legs more or less red. Petiole of 5 rather 

 lightly transrugose. Length 33 mm. ; terebra 50 mm, Yilca- 

 nota, Peru." 



In the type-form the smooth petiole, centrally dark wings, and 

 sculpture of prothorax will distinguish this species from sub- 

 maculatus Westw. and macrurus Schlett., both of which it 

 resembles. The transrugose petiole of Szepligetti's specimens 

 appears to be mei-ely a variety.
