F. C. Fraser : Oriental Ascalaphidae.

three spines on their inner side are equal in size and separated by 

 approximately equal intervals. The head is not coated densely 

 with short bristles ; it is spotted above with dark brown and 

 bears a fine, lateral streak of the same colour. The frontal notch 

 is very shallow and wide. Eyes without the small, horn-like 

 process. 



The prothorax is longer and more evident and has on each 

 side a short, stout, blunt tubercle. 



The lateral spines on the remainder of the body-segment are 

 longer and more slim. The mid-dorsum is marked with a dark 

 pigmented line and each segment bears a couple of fine transverse 

 lines of which the anterior is very sinuous and the posterior more or 

 less straight. The whole body is paler and of a pale brown colour. 



3. A single specimen from Rotung, Abor country, alt. 1300 ft., 

 7 - iii 1912 (coll. S. W. Kemp). Found under stones. (Fig 3.) 



Somewhat similar to the last but the 

 head differing markedly in shape, much 

 more rounded, the sides concave imme- 

 diately posterior to the eyes. The fron- 

 tal border somewhat crenate and the 

 median notch narrow and shallow. Eyes 

 without the horn-like process. Upper 

 surface of head moderately deeply pig- 

 mented save for a pale band which 

 passes between the eyes and is convex 

 posteriorly. Maxillae long, not so sharp- 

 ly curved at the ends, one with its tip 

 bifid, the three inner spines of equal 

 length, the posterior one wider-spaced 

 than the two anterior. Between them 

 and posterior to the hinder, a short and 

 a long series of smaller spines. 



Prothorax narrow and well defined, 

 with similar lateral tubercles to the last. 



Lateral spines of the remainder of the 

 body similar to those of the first des- 

 cribed. Similar, but thicker and darker 

 pigmented transverse lines traversing the dorsum. 



No imagines were collected on the Abor Expedition so that 

 one cannot give any opinion as to which species the two latter 

 larvae belong to. All the larvae are juveniles, so no measurements 

 have been given.
