316 HYMENOPTERA. 



in balsam and captured together with a female of longipes on 

 a window of a greenhouse at Urbana, Illinois, July 27, 1910, 

 or at the same time the original specimen was captured.

Ooctonus lotigipes Ashmead, 1887, p. 192.

 Girault, 1911 a, pp. 19-22). 



An examination of the type or rather original specimen of 

 Ooctonus longipes Ashmead shows that it is a typical Poly- 

 nema. It is the same species designated in the literature as 

 Polynema citripes Ashmead, and which was about to be de- 

 scribed under that name. The name of course will have to 

 be changed to Polynema longipes (Ashmead). The original 

 specimen was found on a tag in the collections of the United 

 States National Museum labelled Ooctonus lo7tgipes Ashmead 

 in Ashmead's handwriting and " Jacksonville, Fla." It also 

 bore a yellow label upon which was written " Type " but no 

 number was in connection with it. It has been remounted 

 in xylol-balsam and designated as the type. It is a female. 

 The species is widely distributed in the United States. No 

 species of Ooctonus have been described from the United 

 States, though there is an Ooctonus honiolodisccB^ a nomen 

 nudum extant in the literature, indicating that the genus is 

 found here.* The species in general appearance resembles 

 a narrow-winged ^' Stephanodes'" {=^ Polynema) and varies 

 considerably in color, the yellow parts varying from pale 

 lemon-yellow to intense chrome orange. The width of the 

 fore wings also varies somewhat. 



I have since captured, or have obtained, the following 

 specimens in Illinois and elsewhere : Mattoon, 111., stable win- 

 dows (July 16, 1910, one female); one female in the National 

 Museum collections bearing the labels: " Cosmocoma 9. 

 Litustemiipennis. From Fitch's collection. 11,901". Another 

 female in the same collection, without labels. A slide in the 

 collection of the National Bureau of Entomology bearing 

 two females and labelled " From C. W. Mally, Wooster, Ohio. 

 Dec. 17, '97. In breeding-cage containing wheat." 



* The Ooctonus mentioned by Girault (1905, p. 92) is a proctotrypid.
