on mesonotum, spot on scutellum, trochanters and anterior coxse yellowish white ; 

 four posterior coxte more or less black at base : remainder of legs fulvous. Al)- 

 domen depressed, tirst segment rugose, same of 2 and 3, except tips ; segments 2 

 and 3 with a reddish band on the border. 



This species is quite uncertain, and is only provisionally placed 

 here. A female before me that differs in having no yellow markings 

 on mesonotum and scutellum and with segment 4 of abdomen also 

 margined with rufous belongs here, and led me to think that Pro- 

 vancher's species belongs in this genus, although the color markings 

 differ and nothing was said of the carinated metathorax and basal 

 segment of the alxlomen. Several male specimens which answer the 

 description have the face smooth and belong to Promethus, where 

 the species probably belongs.
