lines, honey-tubes short, reaching but half way to the tip, black; second segment 
with a downy or pruinose white spot on each side of the middle of the back; three 
next segments each with a short pruinose white band on each side of the back, the 
upper ends of these bands in a line with the spots on the second segment, the first 
and second bands contracted or almost interrupted in the middle; sixth segment 
often with two small faint white dots between the honey-tube3; sevent h and eighth 
segments each with two conspicuous pruinose white spots placed at the corners of an 
imaginary square and in line with the upper ends of the white bands. The kgs are 
pale, usually dull and obscure, with the feet black, and also the ends of the shanks, the 
knees and the hind and sometimes the middle thighs. 
The wingless females are sooty black and from 0.08 to 0.10 long and two-tliirds 
as wide, their bodies egg-shaped, or including the head pear-shaped, the head and 
first segment of the thorax being narrow, their opposite sides parallel, their length 
and width, when taken together about equal, the head being cut off transversely in 
front. The antennae are little more than half the length of the body, yellowish-white, 
dusky or black toward their tips, and their two short basal joints black. They are 
slender and tapering, seven-jointed, the two first joints short and thick, third joint 
longest; sixth shorter than fourth or fifth ; seventh slender and double the length of 
the sixth. Beak black, held under the breast when not in use, its end reaching the 
middle pair of legs. Abdomen frequently showing pruinose whitish dots, more or 
less distinct, along each side of the back ; honey-tubes short, scarcely half as long as 
the distance from their bases to the tip ; tail-like ovipositor protruded frequently to 
half the length of the honey-tubes. Fore legs pale, yellowish-white ; knees, tips of 
shanks and feet black. Middle legs the same, with the thighs black or smoky. Hind 
legs black, their shanks pale, except at the tips. 
The WINGED females are black and glossy, and measure 0.08 to the end of the 
body and 0.16 to the tips of the closed wings. Their antennae are half the length of 
the body, more slender toward their tips, black, with the basal part usually more or 
less pale. They are seven-jointed, the basal joint thickest and short, more broad than 
long, broadest at base and narrowing thence to its apex ; second joint similar in 
length, but less thick, somewhat globular, and twice the thickness of the following 
joints; third joint longest of all, and rather thicker than the following; fourth but 
little shorter than the third; fifth little shorter than the fourth ; sixth shortest of all, 
except the two first, of similar thickness to the two preceding joints ; seventh joint 
long and slender, double the length and half the thickness of the sixth; these joints 
varying, sometimes in the same specimen. Abdomen plump oval, without spots, 
along each side an elevated ridge and a row of punctures; honey-tubes short, equaling 
but half the distance to the tip; ovipositor protruding sometimes half the the length of 
the honey-tubes. Legs black ; shanks pale whitish, their tips black; fore thighs 
pale, rarely smoky; middle thighs smoky or black. Wings clear, hyaline and glassy; 
veins slender, black or brown, third vein abortive at its base a slight distance; rib 
vein pale or white; stigma opake, white, somewhat dusky; second vein rather more 
than twice as far from the first vein at its tip as it is at its base; third vein much 
farther from the second at its tip than at its base, farther from the second at base 
than the second is from the first, its tip a little nearer the first fork than the second 
vein ; first fork at its tip nearer to the second fork than to the third vein; second fork 
at tip equidistant between the first fork and the fourth vein ; fourth vein curved, its 
tip much nearer to the second fork than to the tip of the rib vein. Lower wings little 
more than half the length of the upper pair ; second vein very little farther from the 
first at tip than it is at base, its lip equidistant between the first and the tip of the 
lib vein.
