of this species, two of them labelled "90", a male and a 

 mount of the female head ; they emerged at Washington, 

 D. C, June 23, 1905 from material collected several weeks 

 previously at Fort Valley, Georgia. The third specimen is 

 a female in balsam labelled "91" and '^ Paracentrobia) 

 Chaetostrtcha flavipes {Gixa.\x\i) . U.S. — Georgia. 9 cotype." 

 Reference to the number 91 in my notebook shows that this 

 specimen issued on June 25, 1905 from the same lot of ma- 

 terial. It has been deposited in the collections of the Illi- 

 nois State Laboratory of Natural History at Urbana and 

 given the accession No. 44,194.

Normal position. 



Female. — The same as Ittys ceresarunt (Ashmead) in general aspect 

 and all characters but dififering from it in the following: About a third 

 smaller, moderately large in size ; the general color is pallid greenish 

 yellow (blue green) with the occiput, pronotum (excepting the caudal 

 third) and much of the thoracic pleura velvety black, the velvety black 

 bands of the abdomen indicated along the sides only, not completely 

 crossing the abdominal dorsum ; the fumated spot of the fore wing, 

 the substigmal spot, is a crescentric black spot placed like a continua- 

 tion of the stigmal vein and not reaching farther caudad than half-way 

 to the caudal wing margin or slightly more than half-way ; the rest of 

 the fore wing is practically hyaline ; the fumated substigmal spot nearly 

 clear cut not diffused across the wing as in the species mentioned ; it 

 is also darker in color. 



In structural characters, the antennae differ in being relatively shorter, 

 the scape and club shorter but the pedicel about the same size, very 

 much larger than the funicle joints taken together ; the funicle joints 

 are smaller, both being wider than long, the second funice joint only 

 about half the length of the first and flat somewhat like a ring-joint ; 

 the latter is distinct ; the club is the same but shorter, more ovate- 

 conic. Antennae bearing scape, pedicel, ring-joint, two funicle joints 

 and three club joints. The fore wings differ in the minute details of 

 the venation, mostly in regard to the size of the stigmal vein and the 

 discal cilation. The stigmal vein is distinctly shorter and nearly with-
