duced at the hinder lateral angles, and had its lateral margin slightly den- 

 ticulate anteriorly. The scutellum is large, a little narrower than the breadth 

 of the base of the abdomen, of nearly equal length and breadth, pretty regu- 

 larly triangular, but with a slight emargination of the sides on their basal 

 half; the tip bluntly pointed and rounded off, extending a little way upon 

 the middle of the strongly advanced fourth abdominal segment. The sur- 

 face of the head, prothorax, and scutellum is covered pretty uniformly and 

 abundantly with distinct round punctures, which are, however, deepest, 

 most sharply defined, and so abundant as nearly to occupy the entire sur- 

 face, on the front half of the head and next the margins of the prothorax. 

 The corium of the tegmina includes more than half the wing, and is covered 

 with punctures, deeply impressed, and much minuter and more frequent 

 than on the scutellum ; there is also a distinct vein passing down the middle, 

 a little to one side, and another separating the clavus from the corium, but 

 distinct on the specimen only apically, where it is continuous with the inner 

 margin of the membrane. The membrane is well rounded, but slightly pro- 

 duced at the outer angle, and the space is occupied by nine nearly longi- 

 tudinal veins, distributed in three sets of three each : the first set is composed 

 of three obscure veins, pretty close together next the inner edge, originating 

 from the same point, equidistant from one another, the innermost hugging 

 the inner margin ; from apparently the same point originates the next 

 cluster, starting in a single vein, which almost immediately forks, and sends 

 its innermost branch parallel to those mentioned; the other branch diverges 

 strongly from it and again forks, the two branches running parallel to the 

 first ; while from opposite the point of origin of the last fork the third cluster 

 takes its rise, starting as a shouldered vein, which forks at its shoulder into 

 two slightly divergent veins which run subparallel to the previous veins; but 

 the innermost of these again forks beyond its middle, crowding the veins 

 together at this point. There is also a short, tenth, independent vein close to 

 the outer extremity of the produced coriaceous field. The outer margin of 

 the wing is delicately wrinkled with a simulation of veinlets. The abdomen 

 is ovate, somewhat regularly tapering at its outer half; the apex obscure 

 but apparently regularly rounded ; the pleurae, are punctured like the scu- 

 tellum, while the dorsal surface is minutely and profusely but obscurely 

 punctulate. Such portions of the chitine as remain are of an intense black. 

 The specimen is apparently a male, but whether two small triangular pieces,
