A. A. GIRAULT. 311 



male* (Accession No. 3816) by sweeping in woods, Pekin, 

 111., August 14, 1883 (S. A. Forbes); another single male 

 (Accession No. JJPi) collected at Normal, 111., June 15, 1883 

 (Forbes). 



As the fore wings of this species vary somewhat in width, 

 so that occasionally the largest marginal cilia exceed slightly 

 the greatest wing width, lojigipes may become confused with 

 it. 

 8, Polyueina Sibylla species nova. 



Normal position. 



Feuiale. — Length, 1.50 mm. A large robust species with broad fore 

 wings. 



This species is undoubtedly allied with needhami Ashmead, agreeing 

 with the general original description of that species, but very distinctly 

 disagreeing from the statement made in the original description of 

 needhami that the ovipositor is exserted for two-thirds the length of the 

 abdomen. In this species it is exserted only for about a fourth of the 

 length of the body of the abdomen and thus is not exserted to any 

 great extent, not considerably as is the case with needhami. This spe- 

 cies resembles very closely {Stephanodes) Polyueina enockii (Girault) 

 but may be distinguished at once by its shorter proximal funicle joint 

 of the antenna, which is typical for the genus, distinctly much shorter 

 than the typical long second funicle joint. 



General color deep black, the legs, abdominal petiole, scape, pedicel 

 and proximal funicle joint intense chrome orange, the named antennal 

 joints pale yellow ; also of the legs, the cephalic and intermediate 

 tibias are fuscous, or nearly, the distal tarsal joints black. Venation 

 brown-black like the six distal antennal joints. Wings perfectly hya- 

 line. Exerted valves of ovipositor black. 



Fore wings broad, broader than in howardii, broad and long yet 

 graceful as in Polynema enockii (Girault), the discal cilia moderately 

 fine, arranged in about from twenty-seven to thirty longitudinal lines 

 at the broadest blade portion, the marginal cilia but moderate in 

 length, the longest not quite half as long as the grearest width of the 

 wing, somewhat longer than the longest marginal cilia of the posterior 

 wing. The latter is long and slender, with the usual discal ciliation. 



Proximal tarsal joints long and slender, especially those of the poste- 

 rior legs which are subequal in length to the distal three joints, the 

 second joint in the posterior legs long also, but not quite a half the 



* The males differ only in the secondary character. Their funicle 

 joints are long and slender, longitudinally striate, about six times 

 longer than wide, the distal and proximal flagellar joints subequal, a 

 fourth shorter.
