long and slender, the basal joint shortest, stouter than the second ; 

 second more slender, a little shorter than the third ; third gradually 

 enlarging to the tip, pubescent; fourth and fifth longer, subfusiform, 

 pubescent, slenderly attached, the fifth a little the longest. Buccuke 

 not as long as the head, becoming a little higher behincK, and subrect- 

 angularly terminated. Rostrum extending to the intermediate coxfe ; 

 the basal joint as long as the bucculre ; the second and third longer, 

 subequal ; the fourth subequal to the basal joint, sleuder. Pronotum 

 rather flat, subtrapezoidal (in our species, triangularly narrowing to- 

 ward the fore end); the transverse impressed, line apparent; the lateral 

 margins thick, recurved. Prosternal lateral carin?e obsolete; the meso- 

 sternum with a slightly elevated middle carina. Anterior tibite a little 

 broadened at the tip, on the inner side of which is a short, broad groove ; 

 the inner edge with a very few, almost prostrate, short spines, the outer 

 edge and tip with more numerous, longer spines. Odoriferous plate 

 lanceolate, slightly curved, running two-thirds way toward the outer 

 edge of the pleura, depressed ; the osteole large, situated at the inner 

 end of the plate. Scutellum convex at base, longer than wide, acutely 

 narrowed toward the tip ; the tip narrowed, bluntly rounded, depressed ; 

 the frenum lying close against the margin, almost percurrent. Posterior 

 margin of corium very bluntly obliquely directed, subtruncate, feebly 

 siuuated adjoining the inner angle. Membrane at base thickened ; with 

 about five nervures, two of which are forked at tip. Edge of connex- 

 ivum thickened, compressed, a little decurved.

Blue-black or pitchy black, shining, rather broad-ovate. Head long, 

 rounded and bilobate in front, the lateral lobes curved upward, the sur- 

 face sunken on the middle of each ; coarsely, confluently punctured, the 

 base convexly raised, .smooth, impunctured ; lateral edges recurved, 

 trenchant ; ocelli brown, remote from the eyes, but still more remote 

 from each other ; eyes large, brown, half surrounded by the raised 

 margin of the pronotum. Antennce black, sleuder; the basal joint 

 stout, shortest; the second joint rufescent; apical joint longest Ros- 

 trum blackish piceous, reaching to the intermediate coxip. Pronotum 

 flattened on the disk ; the callosites coalescing, convex, forming the 

 anterior lobe, smooth, impunctured; the remaining surface, excepting 

 the posterior margin and raised lateral white edge, deeply, somewhat 

 remotely punctured ; lateral submargin shallowly grooved, the posterior 

 part of it impunctured ; humeri acutely prominent, the posterior mar- 

 gin interiorly to them a little impressed; transverse impression broad, 

 not reaching the lateral margins; the lateral margins obliquely ap-
