THE ENTOMOLOGIST. 



clypeus sparsely punctured ; sparsely covered with short fuscous hair ; 

 the inner orbits from near the base to opposite the lower ocellus, a 

 2nark on the side of the clypeus, the base of the mandibles broadly, 

 and the palpi yellow. The clypeus not separated from the face by a 

 suture, nor foveate. Mesonotum coarsely reticulated; the sides de- 

 pressed, crenulated ; there is a smooth furrow on either side from 

 nearly opposite the base of the tegulte to the apex. Scutellum smooth, 

 impunctate, its sides keeled ; at its base is a large, deep, smooth, 

 slightly curved depression ; from shortly behind the middle to near the 

 apex it is pallid yellow. The areola is longer than broad ; becomes 

 slightly and gradually wider to beyond the middle, then becomes 

 gradually narrower ; its base is rough ; in the middle at the apex is a 

 stout longitudinal keel ; the posterior median area is stoutly trans- 

 versely striolated ; the spiracular area behind the spiracles is finely 

 rugose, in front of them stoutly transversely striolated. The base of 

 the pronotum has a few curved strife ; above, at the apex, it is 

 irregularly stoutly striolated ; the lower side is stoutly obliquely 

 striolated ; the upper part of the mesopleurae and the apex with a few 

 stout irregular keels ; the rest closely and coarsely punctured, almost 

 reticulated ; the upper part of the metapleurse at the base coarsely 

 aciculated ; the middle at the base with fine stout curved keels ; the 

 rest closely and stoutly reticulated. Mesosternum closely punctured ; 

 the furrow large, wide and triangular at the apex. Legs ferruginous, 

 the fore coxre paler at the base ; the apex of the hinder tibiae and the 

 tarsi black ; the latter spinose beneath. The areolet is narrowed at 

 the top, but the nervures do not touch ; the recurrent nervure is 

 received almost in the middle of the areolet. The petiole is ferru- 

 ginous, yellow at the apex, cariuate down the middle, and striated on 

 the base of the dilated part ; the second, third, and fourth segments 

 are blue ; the second and third closely punctured, the others smooth ; 

 the second acutely striated in the middle between the gastrocceh, which 

 are striated at the base, their apex smooth and brownish ; the apical 

 segments are for the greater part yellowish,

Abdominal segments strongly constricted at the base, and clearly 

 separated ; the constrictions deep and closely longitudinally striated ; 

 the segments longitudinally striated, and broadly depressed laterally ; 

 the petiole raised in the middle, and bearing there two longitudinal 

 keels ; there are seven segments ; the last is small and has stout 

 cerci. Scutellum conical, large, distinctly raised above the level of the 

 mesonotum ; its basal slope is steep, its apical long and gradually 

 sloped from the top to the apex. Post-scutellum smooth, bifoveate at 

 the base, and with a deep depression on either side. The median seg- 

 ment is widely and deeply obliquely depressed at the base ; the areola 

 is represented by a smooth tubercle ; there are three large are* on the 

 apical slope ; the spiracular area being also defined ; there are no 

 spines. Wings larger than usual ; the apex of the abdomen does not 

 reach to the areolet when folded against it ; the areolet is large, five- 

 angled, narrowed above ; the two transverse cubital nervures are 

 roundly curved ; the transverse median nervure is received beyond the
