the apex of the scutelluin more distinct; and the base of the 

 metanotiim has a crenulatnd lateral border at the base. 



EURVTOiMINyE. 

 LissEURYTOMA, gen. nov. 



cf . Marginal vein thrice longer than stigmal, postmarginal 

 shorter than the latter, the stigmal branch as long as the 

 latter, its apex slightly thickened, oblique. Head and thorax 

 not umbilically punctate, smooth, parapsidal furrows distinct; 

 scutellum large. Metanotum flat, triangular, its sides stoutly 

 keeled, flat, the middle with two fine keels. Scutellum large, 

 narrowed towards the base, the apex broadly rounded, mar- 

 gined by a keel. Abdomen with the basal segment sessile, 

 longer than any of the others, the second to fifth of almost 

 equal length. 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 tibiae with one spur. 



The thorax is longer than usual, but not the pronotum ; 

 it is fully one-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. 

 Tlie ocelli are in a wide triangle, in almost a curve. 



A distinct genus. The single spur on the hind tibiae sepa- 

 rates it from all the other described genera, except Phylln.r 

 crorenuii, but that has the thorax umbilicately punctate. The 

 pronotum is not quite so largely developed as it is in 'Enry- 

 toma, and is more distinctly narrowed at the base. 



LiSSEURYTOMA VIOLACEITTNCTA, sp.n. 



Black, abdomen distinctly violaceous, base and apex of 

 tibiae obscurely, and tarsi, testaceous ; wings hyaline, ner- 

 vures black, an obscure cloud, of transversely oval shape,
