of the antennae ; front not tuberculate, but the vertex in the 

 middle above almost raised into a tubercle. OceUi somewhat 

 small, placed in little pits, forming a triangle; clypeus flat, 

 smooth, the margin widely truncate, subrugulose. Antennae 

 convolute, the pints long, the first slender and longest. Thorax 

 compressed. Pronotum transversely wide, square, anteriorly very 

 nearly sharply truncate, posteriorly somewhat arched, above 

 slightly convex. The scutellum triangularly raised in the middle, 

 the apex compressed. Postscutellum arched. Metathorax some- 

 what short, roundly truncate, or better roundly sloped, not 

 tuberculate, posteriorly carinate and striated on both sides, 

 anteriorlv and in the middle posteriorly smooth, not sulcate ; the 

 apical margin well reflexed, the margin obsoletely trilobate, the 

 middle not emarginate ; the anterior lobe of the metanotum 

 nearly hidden in the middle, strongly striate. Abdomen sub- 

 compressed, sessile. Tibiae, the intermediate and posterior sparsely 

 spinose (the posterior pair armed with a double series of 4-5 

 spines), tarsi spinulose. — Black, covered w-ith cinereous and silvery 

 pile all over, head strongly ashy-grey ; the 1-4 abdominal segments 

 with broad silvery bands, the remainder with glittering grey pile. 

 Wings flavo-hyaline, the apex with a broad intra-marginal cloud, 

 the apical margin narrowly hyaline. The radial cell short, the 

 base broad, the apex strongly acuminate ; 2nd and 3rd cubitals 

 minute, nearly equal, anteriorly a little narrowed (the interior and 

 outer margin arched anteriorly), the transverse cubital nervure 

 very oblique; the 1st recurrent nervure is received in the middle 

 of the margin, the 2nd a little beyond the middle of the margin ; 

 4th cubital cellule incomplete, very large ; the cubital nervure 

 ending a little before the margin of the wing, the discoidal nervure 

 reaching up to the margin.

 slightly pubescent, the pubescence somewhat 

 more dense on the median segment and base of 

 the abdomen ; clypeus transversely oval, con-

 in the middle ; median segment somewhat 

 steeply sloped posteriorly, flattened above 

 towards the apex, with the margin transverse; 

 abdomen short, not so long as the head and 

 thorax together, pseudosessile. Black ; the 

 base of the mandibles, the clypeus except a
