the second slightly longer than the first, each also distinctly shorter 

 than the third funicle joint by at least a third ; moreover the third 

 funicle joint is shorter than the pedicel and distinctly longer by a 

 fourth than funicle 4 ; thus funicle joint 4 instead of being subequal 

 to 3 and distinctly longer ihan the pedicel, is shorter than both. The 

 proximal tarsal joint of the caudal legs is shorter than in dolichocerus . 

 From nigritarsis this species differs in antennal structures by having 

 the fourth funicle joint shorter than the third ; its posterior wings are 

 much broader and the coloration of the legs and venation much darker. 



From 1 specimen, f-inch objective, 1-inch optic, Bausch 

 and Lomb. 



Male. — Unknown. 



Described from a single female specimen captured at Pul- 

 aski, Illinois, May 14, 1910, by sweeping along the edges of 

 a cypress swamp (C. A, Hart and A. A. Girault). 



Habitat. — United States: Pulaski, Illinois. 



What is perhaps the male of this species was found in the 

 collections of the U. S. National Museum mounted on a tag 

 labelled " 27 July, 1894. Ithaca, N. Y." 



Type. — Accession No. 44,217, Illinois State Laboratory of 

 Natural History, Urbana, Illinois, one female in xylol-balsam 

 (the female specimen in foregoing). 



6. Gonatocevus fasciatiis species nova. 



Normal position. 



Female. — Length, 1.05 mm., mean. Large, the fore wings broad, 

 the color brown-black or fuscous. Ovipositor not exserted. 



The same as maximus and dolichocerus but differing from both in 

 having a distinct transverse fascia crossing the wing proximad from 

 the end of the marginal vein. In agrees with the former in having 

 the posterior wings not so broadened across the apex of the venation, 

 but differs from it again in having the proximal funicle joints longer 

 as in dolichocerus yet more slender and shorter than in that species. 

 At first the species was mistaken for the last-named species. It is 

 similar to that species in all structures excepting as pointed out. 

 Moreover, it agrees in having the long marginal vein and in general 

 coloration, excepting the fascia on the fore wings. From the species 

 nigritarsis, the fourth species of the large, robust Gonatoceri, it dif- 

 fers in its darker legs, the longer marginal vein of the fore wings and 

 proximal antennal joints and the broader blade of the posterior wings. 

 The following details are all that it is considered necessary to add : 



Fore wings with about thirty (or more) longitudinal lines of discal 

 ciliation across their widest blade portion, crossed at the end of the
