THE CANADIAN ENTOMOLOGIST 247 



as in Ophelosia. Antennae 8-jointed (excluding a very minute 

 ring-joint). Segment 2 of the abdomen occupying the entire sur- 

 face. Scutellum without a delicate cross-suture near apex. Male 

 antennae 7-jointed, the funicle joints as in male Eurytoma, the 

 club as long as the scape and solid; a very minute ring-joint, but 

 not counted. Abdomen with a scanty tuft of hairs at base on 

 each side. A short postmarginal vein, as in Tomocera. Mandibles 

 tridentate, not especially large. 



Tomocerodes americana, new species. 



Female. — Of the habitus and stature of Tomocera genotype. 

 Dark reddish brown, the fore wing infuscated as in the named 

 species, except that the infuscation is rectangular rather than ovate, 

 its ends subtruncate, its proximal end not past the base of the 

 marginal vein (but conical at caudal wing margin and somewhat 

 proximad of the marginal vein) and distad it extends somewhat 

 closer to the apex. Dorsal abdomen (except the sides at base), 

 propodeum (except laterad of the lateral carina except at caudal 

 margin) and all the dorsal thorax laterad of' the axillae and scutel- 

 lum, metallic purplish; also venter of abdomen more or less 

 (especially distad). Club black, the funicle and tibiae washed 

 distincdy with purple. Stigmal vein longer than the shortened 

 marginal. Marginal fringe of fore wing somewhat longer than 

 usual (that is, not extremely short). Pedicel much longer than 

 any of the funicle joints, the latter moniliform, 1-2 subequal, 

 smallest, 5 largest, over twice the size of 1. Club not quite as 

 long as the funicle. Abdomen glabrous. Head and thorax very 

 delicately scaly. Propodeum a little longer at the meson, with 

 median and lateral carinae, the latter closer to the meson than to 

 the minute spiracle; between these carinae, a cross-carina near the 

 cephalic margin (longer) and one near apex, both curved a little; 

 also a looped carina from base of the lateral carina over to near 

 the spiracle. Dorsal thorax with isolated black bristles. Axillae 

 not advanced. Scutum nearly as long as the scutellum. 



Male. — A third smaller and entirely metallic purple, the wings 

 hyaline, the tarsi brown. The scape is still long, but much shorter 

 than in the female, the pedicel globular; funicles 1 and 2 close
