Synonymic and Descriptive Notes ou the Hymenopteia Chalcidoidea. 125 



convexly, both moeting in a point; the venation long and slender, 

 ending in a sniallknob; the discal ciliation consisting of three principal 

 lines, two along the cephalic margin, one aloug the caudal margin, 

 the lattcr line shorter, the former two separated and attaining the 

 venation; in the apex of the blade is a fourth short line of about six 

 cilia, more or less, between the other lines and somewhat confused 

 with the inner ones. Cephalic marginal cilia short, sim.ilar to those 

 along the apical margin of the fore wing but nearly twice longer, 

 lenthening gradually distad, noticeably at the apex, along the caudal 

 margin becoming moderately long, there equal in length to the greatest 

 width of the posterior wings or slightly longer, about equal to a fourth 

 of the greatest width of the fore wings. 



Male: — Unknown. 



Type: Tumidifemur pulchrum species nova, described beyond. 



This genus is an unique one because of its antennal structure, 

 because of the venation, the oblique hairless line of the fore wing 

 and the form of its posterior wings. Like Aphelinoidea Girault, it 

 again shows marked siniilarity to certain Aphelinines and Encyrtines. 



1. Tumidifemur pulchrum species nova. 



Normal position. 



F e m a 1 e : — Length, 0,50 mm. Moderate in size for the f amily. 



General color deep black, most of the thorax, the lower part of 

 face, venation, antennae, knees, tips of tibiae and the tarsi dusky 

 yellow, the legs dusky; posterior wings hyaline. Eyes and ocelli ruby 

 red. Mandibles fuscous. Tegulae black. Fumation of fore wing slightly 

 variable in density, its distal margin convex. 



Knob of stigmal vein with a rather long, slender uncus which 

 points distad; distal club Joint longest of the three. Marginal fringes 

 of fore wing around apex slightly variable, sometimes as long as the 

 cephalic marginal fringes of the posterior wing. 



From six specim.ens, 2/3-inch objective, 1-inch optic, Bausch 

 and Lomb. 



Male: — Unknown. 



Described from six female specimens received for Identification 

 from Mr. F. W. Urich through Dr. L. 0. Howard, all mounted in baisam 

 with specimens of Trichogrammatella tristis Girault (see beyond); 

 three slides, each labelled ,,From eggs of Horiola arquata. Tunapuna. 

 F. W. Urich. Feb. 1911" and bearing respectively three females, 

 two females and one female. 



Habitat: Trinidad (Tunapunta). 



Typ es: Type No. 13,826, United States National Museum., 

 Washington, D. C, two females in baisam (1 slide; mounted with 

 four homotype females of Trichogrammatella tristis Girault). C o - 

 t y p e s — • Accesrsion No. 44,250, Illinois State Laboratory of Natural 

 History, l^rbana, Illinois, three females in baisam (1 slide, mounted 

 with cotypes, three males, four females of Trichogrammatella tristis 

 Girault).
