9 Length 12 mm. Head, thorax and legs yellow, marked with black; 

 abdomen fulvous. Head lemon-yellow; mandibles piceous at tips, and 

 vertex above antennae, except orbits, black; the black enclosing the ocelli 

 and widening out to cover the entire occiput. Face protuberant beneath 

 the antennae and again on the clypeus, smooth, with sparse coarse punctures. 

 Mandibles with two equal teeth; palpi four jointed, the basal joint stouter; 

 vertex and occiput medially shagreened, the latter with a few punctures 

 laterally and sharply declivous behind the ocelli; head margined behind on 

 occiput, temples and cheeks, the latter shagreened, a little broader than the 

 malar space. Ocelli in a curved line, separated from each other and from the 

 eye margin by narrow depressions; front below them irregularly aciculatcd. 

 Antennae filiform, setaceous toward the tips, about 45-jointed; black, except 

 the two basal joints, first flagellar joint five times as long as thick; following 

 growing shorter, those toward the tip becoming nearly as broad as long. 

 Prothorax entirely yellow. Mesonotum with coarse, separated punctures; 

 yellow, with three broad longitudinal black lines, the median one abbreviated 

 tust behind the middle, the lateral ones uniting v-shaped near the base of 

 jhe scutellum. Scutellum shining yellow, very convex, with a deep trans- 

 verse furrow at the base that is furnished with a sharp elevated margin 

 laterally. Metathorax incompletely areolated; with two transverse carinse 

 and one lateral one on each side; spiracles elongate oval; median depression 

 broad, but not deep, lateral ones narrower. Surface of metathorax finely 

 rugulose, entirely yellow except for a median black stripe abbreviated both 

 before and behind, and a thin black line on its anterior suture which meets 

 just above the middle coxa an oblique mesopleural line that extends nearly 

 to the upper anterior angle of the mesopleura. Remainder of pleurae and 

 underside of thorax yellow and sparsely punctate, the oblique black line 

 depressed and irregularly transversely aciculate. 



Abdomen very long and slender, the first segment slightly swollen at the 

 tip, one-half longer than the metathorax; second segment one third longer 

 than the first; third two thirds as long as the second; fourth and fifth sube- 

 qual, each slightly longer than the third; sixth as long as the second with 

 the ovipositor arising from its tip, the apical segments being very short
