no. 3603 HERMETIA JAMES AND WIRTH 3 



this respect although the projection of its face can hardly be con- 

 sidered conelike. Hermetia hunteri Coquillett has a rounded face but 

 bare eyes, and its form, not to mention its genitalia, is so unlike 

 members of the H. aurata group that it could not by any means be 

 confused with them. 



Other characteristics of the group are as follows: The frontal 

 callus is represented by a bare, more or less triangular, area adjacent 

 to each eye; above this, adjacent to the eye, the area is moderately to 

 deeply depressed, at least lightly rugulose, usually deeply sculptured 

 with irregular prominences or longitudinal carinulae (this term being 

 applied to distinct and more or less sharply keeled ridges running 

 lengthwise of the frons) ; between these areas and in front of the ocellar 

 triangle there is a bulbous prominence, which we are designating the 

 "ante-ocellar tubercle"; there is a small, flat callus, sometimes obscure 

 or virtually wanting, just above the antennal bases (the supra-antennal 

 callus). The wings are largely or wholly clouded, frequently with a 

 yellow area, contrasting with the generally brownish clouding, extend- 

 ing at least across the stigma; vein R 2+3 arises beyond cross-vein r-m: 

 the wing is largely set with microtrichia, the basal part and at least a 

 narrow anterior margin of cell 1st A being bare. The abdomen is 

 ovate or elongated ovate, the sides of the second to fourth segments 

 parallel, except in H. anthidium in which the abdomen is more rounded. 

 The vestiture of the abdomen tends to form dense areas of long, 

 appressed yellow to golden pile, particularly on the terminal terga; 

 this pile is especially dense in such species as H. aurata. The genitalia 

 (fig. 8) present a moderately uniform pattern with some variations. 

 What we interpret to be the dististyle has migrated ventrad and 

 laterad of the basistyle so as to appear like a lower lobe of the latter; 

 from side view, in this group, we see chiefly the basistyle, with the 

 dististyle ending far before the apex of the basistyle and appearing 

 as a small angulated or rounded ventral projection (figs. 3-6). 



Key to Species of the Hermetia aurata Group 



1. Vanelike style of female flagellum (male unknown) acuminate, white at apex; 



abdomen short and robust, not much longer than wide, and black with 

 narrow interrupted tegumentary yellow apical bands on terga 2 to 4 



anthidium James, new species 



Vanelike style of female flagellum rounded at apex, sometimes acute but 



never acuminate and never white tipped; abdomen 1.5 to more than 2 times 



as long as wide and without tegumentary pale markings beyond th( j second 



tergum though the general coloration of the abdomen may be reddish . 2 



2. Tibiae entirely yellowish, at most somewhat orange or orange yellow on apical 



third to half i 



Hind tibia, at least, distinctly blackened or brownish black on apical third 

 or more 5
