Synonymic and Descriptive Notes on the Hymenoptera Chalcidoidea. 127 



applied to the first tarsal Joint, not forked and not forming a strigil; 

 but the intermediate tibial spurs are comparatively very long and 

 slender, thrice or niore the length of the others. Posterior tibiae 

 obclavate. 



Fore wings as in Trichogramma Westwood; discal ciliation arranged 

 in regulär rows (about from ten to fourteen), the rows arranged in 

 more or less distinct pairs with the exception of a straight line leading 

 directly distad from the apex of the stigmal vein, consequently from 

 the cephalic niargin, three pairs, then a single line, then four pairs; 

 ciliation moderately sparse, two central lines projecting irregularly 

 beneath the venation as far as the tip of the submarginal vein and 

 from thence proximad, absent; absent near the venation; an oblique 

 line of five or six cilia leads proximo-caudad from the end of the 

 stigmal vein; it nearly joins the end of the three or four smaller cilia. 

 Discal ciliation distinct but not long or coarse. Several isolated cilia 

 proximad bordering either side of the venation^). Marginal cilia short, 

 slightly longer than normal for Trichogramma, but not more than 

 an eighth of the greatest wing width, longest around the apex; in the 

 male, the cilia are somewhat longer. Venation of fore wing forming 

 a bow but the marginal vein is only slightly curved, slightly shorter 

 than the rather long, slender, curved stigmal vein, only a third of the 

 length of the submarginal; stigmal vein with a long neck, ending in 

 an ovate knob which bears a nipple-like uncus pointing disto-cephalad. 

 Posterior wings short, reaching only aibout to the end of the stigmal 

 vein of the fore wing, the blade knife-shaped from the apex of the 

 venation only about twice wider than long, its apex obtusely pointed; 

 three complete lines of discal ciliation, the posterior line faint, the 

 longest marginal cilia about equal to the wings greatest width, or 

 slightly shorter; venation long and slender, slightly enlarged at the 

 end. There may be a single discal cilium caudad of the second line 

 of cilia of the caudal wing near its proximal end ; it is usually missing. 



Type: Trichogrammatella tristis species nova, described herewith. 



1. Trichogrammatella tristis species nova. 



Normal position. 



Female: Length 0,40 to 0,55mm, Moderate in size for the 

 family. 



General color sooty black, the scutellum pale cadmium yellow; 

 scape and pedicel yellowish ; club dusky yellowish ; knees, trochanters, 

 tips of tibiae and all tarsal joints pallid; venation dusky; fore wings 

 slightly f umated proximad under the submarginal vein ; posterior wings 

 hyaline. Mandibles fuscous. Eyes dark. 



Pedicel of antenna dorsad with a ridged sculpture, in outline 

 along the edge appearing like serration; the caudal femora with 

 longitudinal striation. 



From 12 specimens, 2/3-inch objective, 1-inch optic, Bausch 

 and Lomb. 



*) For instance two in the rather broad costal cell.
