 — Blsfck. Head very finely punctate, less densely on the vertex, very 

 densely on the face, which is covered with sparse, cinereous pubescence. 

 Orbits narrowly white from the top of the vertex nearly to the mouth. 

 Clypeus, mandibles except their teeth, and palpi, white; the clypeus 

 sometimes pale dull rufous. Antennae \ as long as the body, brown- 

 black, dull rufous beneath towards the tip. Thorax subopaque with fine 

 dense punctures, the metathorax more coarsely rugoso-punctate, the two 

 normal longitudinal carinze represented only by a single obtusely im- 

 pressed stria. Tegulae and a spot before them, a short line under the 

 front wing, an elongate robust line generally widened above near the tip 

 :and overlying the humeral suture nearly to its tip, a large Y-shaped spot 

 on each side of the meso- sternum (the prongs of the Y very rarely subobso- 

 lete), a geminate spot on the hind end of the mesosternum very rarely absent, 

 and the sides and tip of the scutel, all white. Disk of the scutel except in 

 a single specimen, meso- and meta-sternum below and halfway up their 

 pleura, and occasionally an indistinct vitta above the front wing, all ru- 

 fous. Abdomen subclavate when viewed from above, owing to the length 

 •of the ist joint and joints 6-8 being chiefly retracted. Joint i with only a 

 ibasal trace of the normal carinae, 2J times as long as wide and i wider 

 ibehind than in front, with the sides straight. Joints 2-4 with their sides 

 parallel, 2 and 3 equally long and each J shorter than i, 4 shorter by \ 

 than 3, and 5 about i as long as 4. All the visible joints very finely, 

 closely and evenly rugoso-punctate so as to be subopaque. Ovipositor 

 nearly as long as the abdomen, piceous ; sheaths broad, tapered to a 

 point, and with very fine, short, dense ciliations. Venter with the sutures 

 broadly whitish. Legs pale rufous, the 4 front coxae except the lower sur- 

 face of the middle ones, both trochanters of the 4 front legs, the terminal 

 one of the hind legs, and also the hind knees, all whitish. Tips of the 4 

 front tarsi, extreme tips of the hind femora up to the whitish knees, an 

 «xterior vitta on the hind tibia extending from the knee to the tip and 

 towards the tip extending all around, and the whole of the hind tarsi, all 

 pale fuscous. Tarsal claws with very long pectinations. Wings sub- 

 hyaline; veins black, radius rufous; stigma rufous edged with black, and 

 3 times as long as wide. Areolet rhomboidal, the peduncle as long as 

 the rhomb. Length $ .41-.4S inch. Front wing $ .3S-.37 inch. Ovipos. 

 .27 inch.
