ORTALID^E PYRQOTA. 75 



which occupy everything but the humeri and the narrow intervals 

 between the stripes, so that the prevailing color is the brow-n - 

 one; the middle stripe, which is of equal breadth, is longitudi- 

 nally divided in two by a lighter longitudinal line ; the stripe 

 stops at the last quarter of the thorax, however, beyond it, at 

 the posterior margin of the thorax, there is a brown spot ; the 

 very broad lateral stripes are strongly abbreviated anteriorly, 

 attenuated and interrupted at the transverse suture ; moreover, 

 the lateral margin has a broad brown border. Scutellum 

 blackish-brown, paler on the sides ; the numerous bristles are 

 more conspicuous in this species on account of their stoutness 

 and their black coloring. Pleurae pitch-brown, clay-yellowish 

 on the sutures. Abdomen usually blackish-brown or dark pitch- 

 brown, sometimes ferruginous-brown or yellowish-brown ; the 

 first segment is about once and a half the length of the four fol- 

 lowing segments taken together. The capsule-shaped ovipositor 

 is of the same color as the abdomen, or somewhat paler; its 

 shape is nearly the same as in P. undata, but it is a little less 

 pointed ; on each side, not far from the basis, it has a large, im- 

 pressed spot. The color of the feet is as variable as that of the 

 remainder of the body ; blackish-brown in more intensely colored 

 specimens, otherwise ferruginous-brownish ; the knees are always 

 clay-yellow ; paler colored specimens have the extreme tip of 

 the tibia? and the tarsi of a dirty ferruginous-yellow or ochre- 

 yellow color. The shape of the wings is not unlike that in P. 

 undata, but towards the apex they are broader. The chief dif- 

 ferences in the venation are the following : the little stump of a 

 vein on the second longitudinal vein existing in P. undata, is 

 wanting here ; the discal cell is much broader, especially towards 

 its tip ; the posterior transverse vein is nearer the margin of the 

 wing, much longer and more straight ; the last section of the 

 fourth longitudinal vein is less strongly arcuated and the second 

 posterior cell much smaller; the posterior angle of the anal cell 

 is more drawn out in a point. The whole surface of tlu wings 

 has a rather uniform dark -brownish coloring ; this color is varie- 

 gated by numerous transparent dots of a gray-yellowish tinge ; 

 the shape of these dots is rather irregular; they are often con- 

 fluent, as often distinctly separated ; round the root-of the second 

 longitudinal vein and round the small crossvein, the dark color- 

 ing is more continuous and less interrupted by dots ; the brown
