Hymenoptern from Central America. 375 



nervure is received at a sliglitly greater distance from the base 

 than the second is from tlie apex of the cellule. 



A very distinct species. It belongs to my first section of 

 the genus, near F. impudicus^ Cam. 



Pompilus ri'nconensis, sp. n. 

 Long. 18 millim. $ . 



Hah. Rincon in Guerrero (Z7. H. Smith). 



Agrees closely with P. impudicus^ Cam., from Panama, 

 but it is much larger ; the pile on the thorax is not orange, 

 the head only hairy at the top, and the hinder ocelli are 

 separated by a greater distance from the eyes. 



Black : the prothorax, the base of the mesonotum, and 

 the third and fourth abdominal segments covered densely 

 with orange pubescence ; the top and sides of the median 

 segment, the sides and apex of the basal abdominal, and the 

 first to the fourth ventral segments, the sternum, and the 

 legs, densely covered with a greyish pruinose pubescence. 

 The wings smoky, with a cloud before the transverse basal 

 nervure, one in front of it, and the apex milky hyaline. 



Antennae short, black ; the apex of the scape, the second 

 joint, and the base of the third rufous ; the flagellum covered 

 with a microscopic down. Head shining, impunctate ; the 

 vertex behind the ocelli densely covered with golden pubes- 

 cence ; the hinder ocelli separated by a much greater distance 

 from the eyes than they are from each other. The black 

 central part of the thorax has a slight violaceous tifige. The 

 sternum, the sides of the pleurae above it, and the metapleuric 

 densely covered with a greyisii pile. The apex of the median 

 segment black, slightly excavated, the sides with some stout 

 transverse striolations. The first and third transverse cubital 

 nervures are roundly curved, the second straight and hardly 

 oblique ; the first recurrent nervure is received in the apical 

 third, the second almost in the centre of tlie cellule. 



A second specimen, from Iguala in Guerrero {Hoge), no 

 doubt belong^s to the same species ; it has the pile on the 

 thorax and head deep orange, this being also the case with 

 tiiat on the fourth and fifth abdominal segments, the sides of 

 the pleurae entirely covered with a grey pubescence, and, 

 apparently, the abdomen is a little longer compared to the 

 length of the thorax ; it is also smaller.
