brown, hind tibiae at times dusky brown as in dubia,' submarginal 

 band in color, size, and form as in dubia; abdomen dark brown to 

 black, except that antero-ventral part is in small part light brown 

 to brownish yellow. 



The dimensions of the head, the measurements of the antennal 

 joints, the sculpturing and the vestiture of the parts, including the 

 number of setae on the submarginal vein, agree with the typical 

 dubia. 



Male. — Differs from the female only in being slightly smaller on 

 the average, and in the dimensions of the antennal joints, the latter 

 agreeing with those of dubia. 



Type locality. — Charleston, S. C. 



r2/;?e.— Female, U.S.N.M. No. 42235. 



Described from the type, the allotype, and five female paratypes; 

 type, allotype, and three paratypes in collection of the United States 

 National Museum, and two paratypes in the writer's collection. 



Remarks. — All the type material was reared from the galls of 

 Belonocneina fossoria Weld [Disholcaspis virens (Ashmead)] at 

 Charleston, S. C, by J. T. Rogers and Charles Pon. One specimen 

 of the series bears a label " Rohwer 2015 " and " Pon 287." 



In addition I find the following of this variety : 6 females (No.

 Patton at Selma, Ala., in October, 1880, and the chalcids issued 

 December 16 of that year; another series (165^°^) of 4 females,
