pepsinae: tribe macromerini 215 



at Raleigh, N. C, indicate that the period of greatest abundance 

 there is July, August, and September. Both sexes have been taken 

 commonly at nectaries of Cassia ■nictitans, and the species has been 

 collected also on Euphorbia marginata, Baccharis glutinosa, and Bifora 

 americana. The females seem to hunt primarily on ground with 

 sparse, short vegetation such as on run-down lawns or abandoned 

 eroded fields. They run over the ground with the abdomen tucked 

 forward in a way that gives an appearance like that of Pogonomyrmex. 

 There is also a resemblance to some female mutOlids. When at 

 nectaries among vegetation they crawl about with the abdomen in a 

 normal position and look much like a large Formica pallide-Julva. 

 Females are slow to take flight, which increases their antlike appear- 

 ance. 



This species is transcontinental in the Lower Austral Zone. Adults 

 are on the wing in the warmer months.

 its basal 0.35 (in the other subgenera receiving the second recurrent 

 vein near or beyond its middle) ; sixth sternite of male with a median 

 apical, weakly raised, rounded ridge, on each side of which the sternite 

 is impressed; subgenital plate narrowly tectate, variable. 



Coloration of tibial spurs of male variable.
