EUPACHYGASTER PUNCTIFER Malloch 



Eupachyfiastcr punctifer Malloch, Aim. Ent. Soe. Amcr., Vol. 8, 1915, p. 316. 



The eyes are marked and colored as in henshazvi except that the 

 anterior margin does not have a distinct stripe and that the other 

 stripes are broader, the violaceous blue one continuing almost to the 

 lower margin. The thorax has a central narrow stripe of silvery pile, 

 the lateral portions of the disc being adorned with punctiform groups 

 of similar pile. The basal half of the abdomen is devoid of puncti- 

 form groups of silvery pile. 



This species was described from a single female specimen taken 

 by Dr. Nason at Algonquin, 111., which bears no date of capture. 



The other specimen referred to in the notes on this species given 

 under the original description belongs to the next species. I took a 

 female example of punctifer in a wood near an old orchard at White 

 Heath, 111., June 24, 1916.
