rounded, the prothorax conical, long, its lateral dorsal margins carinated, the 

 region nearly as long as the mesoscutum, but remote from the tegulse, its 

 caudal margin much concaved. Scutellum subquadrate, slightly longer than 

 wide, flat, its sides margined, with no longitudinal grooved lines, but trans- 

 versely near its apex is the usual transverse line of minute punctures, in this 

 species weak and somewhat irregular. Mesopostscutellum transverse, not a 

 sixth the length of the scutellum, its cephalic margin apparently a line of very 

 minute punctures or striations ; metathoracic disk, or that portion between the 

 lateral carinae small, triangular, elevated, with no median carina, the lateral 

 carincE of the metathorax distinct, converging, meeting in a point at the apex 

 of the metathorax ; laterad of the true lateral carin^e, caudad, not quite in a 

 line longitudinally with the spiracle, is a complete carina or fold, less con- 

 spicuous cephalad but proceeding nearly to the spiracle and curving slightly ; 

 and still farther laterad, in the center of the dorso-lateral aspect of the meta- 

 thorax is an oblique (caudo-mesad or cephalo-laterad) carina or fold ; meta- 

 thoracic spiracle minute, circular, not touching the postscutellar folds. 



Petiole of abdomen dorsad at base, convex or slightly obtusely barbed, 

 smooth. Abdomen not compressed, (dorsal, lateral aspects) conic-ovate, the 

 petiole not quite half the length of the body of the abdomen, subequal in 

 length to the antennal club and the caudal coxae, but somewhat longer than 

 either. (Dorsal aspect) segments 2 and 3 of the abdomen subequal, occupying 

 somewhat over half of the surface, each slightly shorter than the petiole ; 

 segments 4 to 8 all subequal in length, each not quite half of the length of 

 either segments 2 or 3 ; caudal margins of the abdominal segments straight ; 

 exserted sheaths of the ovipositor not quite half the length of the abdomen 

 (excluding petiole). Body smooth, somewhat shining but the head and the 

 notum of thorax (excepting the metathorax) exhibit a fine polygonal reticula- 

 tion, somewhat scaly in appearance ; abdomen with no perceptible sculpture. 

 In addition to the carinse on the metathorax there are also two inconspicuous 

 oblique grooves along the dorso-lateral aspect of that segment laterad of the 

 second carina (the one at the spiracle). 



Trochanters 2-jointed; tibial spurs single, the cephalic ones forked and 

 curved, the cephalic proximal tarsal joint ventrad with the corresponding 

 strigils. Petiole of abdomen smooth, not sculptured. Along the ventro- 

 lateral aspect of the prothorax is a margined groove extending from the 

 insertion of the cephalic coxa, cephalad to the head ; it is broadly convexed 

 and is just ventrad of the deep, conspicuous femoral furrow of the pro- 

 pleurum. 



Submarginal vein narrow, straight, the marginal much broader, twice 

 longer than broad but not distinctly long as in Stichothrix ; in all of the speci- 

 mens in the National Museum collection the third fuscous band of the fore 

 wing, crossing slightly distad of the widest part of the wing, is rectangular, 

 not narrowing at all caudad, the distal and proximal margins nearly parallel 

 but the distal margin is often broken and irregular ; both the second and 

 third fuscous bands or areas may be faiinter or absent at the immediate
