meister's P. spiniceps. The character of the spines of the 

 head, even supposing the locaUty of "India orientalis" to 

 be incorrect, seems to militate against such an opinion.

The general appearance of the unique female hitherto 

 known of this species, formerly in my Collection, is so 

 similar to that of Phasnia Horstokkii of De Haan, that, 

 were it not for the difference of locality, I should be tempted 

 to consider them as varieties of the same species. The 

 suggestion of De Haan, that it is possibly identical with Pr. 

 spinicollis, is destitute of foundation. I can find no generic 

 characters to separate this species from the typical Prisopi.

This species is depressed, of a brown or greyish-brown 

 colour. The head, pro- and mesothorax, and extremity of 

 the abdomen thickly covered with small granules of a 

 whitish colour ; the hind part of the head also with larger 

 tubercles, of which the hinder form an irregular transverse 

 series rather larger than the rest. The antennse are setose, 

 rather thick, with the fourth and following joints short, but 

 gradually lengthening ; in the male they are 25-jointed. 

 The pro- and mesothorax are nearly of equal size and ap- 

 pearance, being rugose ; the former is spiraculiferous at its 

 fore angles, the sides being rather dilated in the middle. 

 The metathorax is as long as the pro- and mesothorax 

 united, its hinder division being nearly twice as long as the 

 fore part. The abdomen is narrow and parallel in the 

 male, but broader and gradually widening to the sixth seg- 

 ment in the female, the sides being strongly deflexed ; the 

 fifth and follovring segments produced at their posterior 

 lateral angles into a rounded, setose, deflexed lobe ; the ter- 

 minal ventral segments in both sexes are flat, and the anal 

 styles are long and flattened. The metasternum is marked 

 on each side with a black spot, and the ventral segments of 

 the abdomen are fasciated with black. The tegmina are 

 about two-thirds of the length of the wings, brown or 

 greyish, varied with darker shades, the colour of the veins 

 being more or less interrupted ; the main vein is elevated 

 near the base into a small tubercle. The wings are large, 

 opake whitish, with the transverse veins very broadly 

 stained with brown ; the costal area is strongly shaded with 

 pink throughout its greater portion, varied with brown 

 patches with paler round spots ; the apex is more uniformly
