One male, one female. 



A lar^e inseet, with no parallel amongst strictly European 

 forms. In contour of wings it resembles the Jiiuropean Sfcno- 

 phyhix concentricus, M'Lacli. et auct. (nee Zett.), but is 

 larger and darker. 



Stenopsi/che griseipennt's, M'Lach. 



Three males and one female. 



This identification is based on the supposition that one 

 species, varying much in size and in intensity of colour, 

 extends from the Himalayas, through North China, to Japan 

 and the Loo-Choo Islands, a point that requires an exhaustive 

 study to decide. The examples here under consideration 

 have the anterior wings very darkly marbled and the posterior 

 very opaque white, with broad fuliginous apex ; some ex- 

 amples from kSikkim &c. in the Himalayas are similar in this 

 respect ; the smoky apex of the posterior wings appears to 

 be only a matter of degree. At the most I think these can 

 only be local forms, not perhaps sufficiently differentiated for 

 specific distinction.

 Panorpa diceraSj sp. n. 



Body pale orange-yellow, with black markings as follows: — 

 on the liead is a large spot in wliich the ocelli are [jlaccd, 

 continued as a fine line between the basal joints of the 

 antennae and expanded into a triangle on the front below 

 them ; rostrum with two lines gradually convergent towards 

 the apex ; a line on either side of the body commencing 

 on the prothorax and continued to the end of the fitth 

 abdominal segment, broadest on the basal segments. 



Antenna? and palpi black. Legs greyish yellow, with 

 short blackish pubescence ; tips of tarsal joints blackish, the 

 last two joints of the intermediate and posterior tarsi nearly 

 wholly blackish ; spurs piceous ; claws testaceous, with three 

 or four long comb-like teeth within. 



"Wings moderate, subobtuse, dusky hyaline, the extreme apex 

 pale fuliginous; otherwise without markings, save that the ptero- 

 stigma is yellowish and rather long. Subcosta not extending 

 to the pterostigma in either pair. Neuration black, but the
