126 ^' Arsöne Girault: 



Genus Westwoodella Ashmead. 



1. Westwoodella sanguinea Girault. 



There is very little doubt but that Westwoodella clarimaculosa 

 Girault (1911) is a color variety of this species and should therefore be 

 designated as Westivoodella sanguinea clarimaculosa Girault. It agrees 

 in all structural details with sanguinea but resembles somewhat the 

 male described for that species. With sanguinea, thus, there are two 

 colorational forms for the female while the males so far seen resemble 

 clarimaculosa. Very recently (April 30, 1911) I captured a male by 

 sweeping clover in grass at Oakwood, Illinois. From this specimen, 

 the Vertex was seen to be minutely, densely punctulate, the m.etanotum 

 ending in an acute point. It was pale green in color, the substigmal 

 spot very conspicuous, as usual. 



Subfamily Trichogrammatinae. 

 Trichogrammatella genus novum. 



A genus resembling Trichogramma Westwood in the form of the 

 fore wing and its venation, but differing in antennal structure (the 

 funicle absent, the many-jointed club), in the structure and shape of 

 the posterior wings, in the shape of the abdomen and in the long slender 

 tibial spur of the intermediate legs. Also, the fore wings resem.ble those 

 of Trichogrammatoidea but the oblique line of discal cilia is present. 

 The genus may be recognized at once by means of its 5-jointed antennal 

 club, its curved venation and the short and broad posterior wings. 



Male, female: — Head normal, the eyes large, the ocelli 

 normal, in a triangulär curve in the center of the Vertex, the 

 antennae inserted slightly below the middle of the face, 8-jointed 

 — scape, pedicel, 1 minute ring-joint and a 5-jointed club; scape 

 moderate in length, cylindrical, about twice the length of the 

 pedicel; the latter obconic, narrow proxim.ad, longer than any of 

 the club joints, rather long; ring-joint shallow and narrow; club 

 long, nearly as long as the scape and pedicel combined, long- 

 acuminate, its five joints unequal but none very long, the second and 

 fourth joints longest, the first Joint shortest, transverse, not always 

 distinctly separated from the second, the first incision straight, the 

 others oblique or obliquely curved. Pubescence of antennae sparse, 

 in the male slightly less so. Mandibles tridentate. Parapsidal furrows 

 complete, distinct, oblique, straight. Abdomen slightly longer than 

 the thorax, with parallel sides and subtmncate or blunt apex somewhat 

 as in the males of Lathromeris Foerster but not so long, shorter and 

 conical in the male with the genitalia exserted; ovipositor and its 

 valves as in Tumidifemur. Legs normal but the posterior femora 

 swoUen somewhat as in Tumidifemur but not as much; trochanters 

 2-jointed; tarsi 3-jointed, the joints rather long in the intermediate 

 legs, the proximal Joint there twice the length of the same joints in the 

 other legs where all the joints are short but longer than wide; tibial 

 spurs Single, short, straight, acute, those of the cephalic tibiae closely
