412 ANNUAL REPORT OF NEW- YORK 



GRAPE. LEAVES. 



ing veins have already been described. In the female the iving covers are quite 

 unlike those of the male, being much narrower, and wrapped more closely 

 around the body, giving this sex a more slender form. The flattened upper 

 portion is cut up into many small cells which are mostly square and are formed 

 by six or seven parallel veins which arise from the base of the wing covers and 

 from the inner rib-vein and run obliquely backwards and slightly inwards to 

 the inner margin, and are connected to each other by numerous transvei-se 

 veinlets. The deflected outer or costal area is similar to that of the males. 

 The longitudinal rib-veins do not form any elliptic area like that in the 

 male. The wings are folded together lengthwise under the wing covers, 

 and are of the same length with them in the male, whilst in the female the}'- 

 are longer and project beyond their tips the eighth of an inch or more, resem- 

 bling little conical tails. 



The four forward legs are rather slender and of moderate length and clothed 

 with fine short soft hairs. The thighs are cylindrical and have a shallow groove 

 along their under side. The shanks are but half as thick as the thighs and 

 taper slightly towards their tips. The forward ones near their bases are flat- 

 tened and widened and show on both sides a deeply impressed oval and almost 

 transparent spot appearing like a scar. The feet have three joints, of which 

 the first one is long and cylindrical, the middle one is very small and only 

 about as long as it is wide, and the last one with the claws at its tip does not 

 difier from the same joints in the hind feet. The hind thighs are very long and 

 slender, nearly equaling the tip of the wings and of the ovipositor. The}' are 

 much thickened towards their bases, flattened on their inner side and stronglj- 

 convex or rounded on their outer side. They have a narrow straight groove 

 running their whole length, both on the inner and the outer side, and an ele- 

 vated line along their lower edge. The hind shajiks are also long and \itry 

 slender and thread-like, equaling the thighs in their length and like them 

 clothed with very fine short soft hairs, in addition to which they have along 

 their hind side two rows of small sharp spines or prickles which reach almost 

 to the knee, with three or four pairs of coarser ones towards their lower end, 

 and a crown of coarse ones at the tip whereof two are much longer and have 

 small thorn-like points branching from them. All these spines are white with 

 their points black. The hind feet are covered with minute spines or thorn-like 

 points, which are very densely crowded on their under sides. These feet 

 have four joints, one more than is found in other insects of the cricket kind, 

 but the articulation to the middle of these joints is so slight in the present 

 species that it is often wholly imperceptible in the dried specimens. The basal 

 joint is long and cylindrical and forms three-fourths of the total length of the 

 foot. The second joint is of the same diameter with the first, but is quite 

 short, only as long as wide, with the suture at its base slight and often dis- 

 cerned with difiiculty. It is cylindrical and divided into two parts by a suture 

 running lengthwise upon each side. The upper half forms two large sto: t 

 spines, the bases of which are articulated to the apex of the first joiiit, tin ir 

 lower edge is joined by a suture to the lower half of this second joiut irs 

 whole length, their tips only being free, jutting onward and overlaying tlie 

 third joint more than half its length, each spine tapering to a point which is
