Genus LISSEURYTOMA Cameron. 



' ' Marginal veiu thrice longer than the stigmal, postmarginal shorter than the latter, 

 the stigmal branch as long as stigraal, its apex sFightly thickened, oblique. Head and thorax 

 not umbilicately punctate, smooth, parapsidal furrows distinct; seutellum large, narrowed 

 toward base, the apex broadly rounded, margined by a keel. Abdomen with the basal segment 

 sessile, longer than any of the others, the second to fifth of almost equal length. Metanotum 

 flat, triangular, its sides stoutly keeled, the middle with two fine keels. Eyes ovate, the lower 

 side more sharply pointed than the upper ; malar space two thirds of their length. Antenna 

 12-jointed, stout, third joint conical, longer than wide, fourth and fifth as wide as long, the 

 others wider than long. Legs stout, hinder tibiije with one spur. 



The thorax is longer than usual, but not the prouotum; it is fully oue-half longer than 

 the abdomen; the flattened, only slightly sloped metanotum adds to its length. The head is 

 transverse behind; the temples are very slightly developed. The ocelli are in a wide triangle, 

 in almost a curve. 



A distinct genus. The single spur on the hind tibiai separates it from all the other 

 described genera, except FJiyHoxeroxenus, but that has the thorax umbilicately punctate. The 

 pronotum is not quite so largely developed as it is in Evriitonia, and is more distinctly narrowed 

 at the base. " 



1. LISSEURYTOMA VIOLACEITINCTA Cameron. Male. Genotype. 



Length, 4 mm. 



"Black, abdomen distinctly violaceous, base and n]iex of tibia> obscurely, and tarsi, 

 testaceous; wings hyaline, nervures black, an obscure cloud, of transversely oval shape before 

 the stigmal branch. Pro- and mesothorax opaque, pro- and mesonotimi very closely, finely, 

 transversely striated in front. Metanotum smooth shining. 



The hair on the legs and metai)leura> is longer than elsewhere ; that on the legs is long, 

 white and sparse. Hind tibia> flattened, broader than the others; metatarsus as long as 

 second and third joints united, and a little shorter than tlie apical. The apex of the antennal 

 scape does not reach much beyond the middle of front, nor do tlie antennal depressions.

 antenna?, except narrowly at apex, anterior nuirgin of mesonotum and sutures dividing sclerites 

 of thorax, black. Wings hyaline, ])ubescent, the veins bi'own, the subcostal vein interrupted 

 by a w'hite bulla at its junction with the marginal vein; marginal and postmarginal veins
