funicle joint; pedicel subglobose, (lateral aspect) dilated ventrad, slightly convex 

 dorsad, compressed, with a short, slightly curved proximal neck, slightly more 

 than a half the length of the proximal funicle joint Init much wider, its greatest 

 width about equal to that of the scape (dorso-ventrad). 



(From 7 specimens, two thirds inch objective, one inch optic, Bausch and 

 Lomb.) 



Described from 7 males and 10 females reared from the egg- 

 masses of the membracid Enchcnopa hinotaia (Say) at Chicago, Illi- 

 nois, September 15, 1908 (J. J. Davis). The eggs of the host were 

 on Ptclca. 



]\rore closely related than the preceding to maculipcs Ashmead 

 and Iiowordii Ashmead, differing from the former (male type) in 

 having relatively finer discal ciliation of the fore wings (abotit 12 

 lines, macnlipes but 10), in the broader fore wings, in maculipcs the 

 longest marginal cilia of those wings being seven eighths the greatest 

 wing width, but in this species only about three fourths and in the 

 general coloration of the legs. From the species hozvardii Ashmead 

 in having distinctly coarser discal ciliation of the fore wings and in 

 different wing shape ; also in different coloration of the antenna. 

 A moderate sized species.

As stated, the foregoing two species are related to maculipcs 

 Ashmead and hoxvardii Ashmead, whose identities are considerably 

 mixed in the Ashmead determinations (in the U. S. N. M. collection 

 for instance) ; from all others of this country and of those described 

 since de Dalla Torre's catalogue, easily distinguished. From piccipcs 

 (lirault by the longer distal funicle joints of the female antennae 

 and the wider fore wings ; rcduvioli Perkins by the short proximal 

 funicle joints; hawaiicnse Ashmead by the shorter antennal joints; 

 nccdhami Ashmead, hrasilicnsc Ashmead, grcnadcnsc Ashmead, and 

 albicoxa Ashmead by the lack of an exserted ovipositor; magniccps 

 Ashmead by thoracic characters and from hcrgi Ashmead and 

 rnfcsccns Ashmead by having hyaline wings and in being black in 

 color, respectively.
