1902.] DKAGOXFLIES OF THE " SKEAT EXPEDITION." 383 



A very beautiful and striking species. I believe that the 

 female has not as yet been described ; it diffei^ markedly from 

 the male and is fully as brightly coloured. I append a short 

 description of it : — 



2 . Head, prothorax, and thorax nearly as in the male, the 

 yellow rather less vivid, and the black stripes on the upper lip 

 and epistome continuous with the black markings near the base 

 of the antennae. 



The abdomen is chestnut-brown above, but the first segment is 

 yellowish green. Segments 2-6 each with a black apical ring 

 feebly developed on the second segment. Immediately before the 

 apical ring there is on each of these segments a dorsal yellowish- 

 green mark, extending forward in 2-3 for about one-half, and in 

 4-6 for about one-third, of the total length of the segment. This 

 mark is divided longitudinally in each segment by a thin brown 

 line on the mid-dorsal carina. 



In segments 3-6 the black apical ring sends forward on either 

 side of "the segment a black line, extending nearly the whole 

 length of the segment. 



In the seventh segment the anterior half is black, and the 

 yellowish-green marking here is divided into two parts, well 

 separated from each other and diverging posteriorly, the space 

 between them being occupied by a triangular extension forward 

 from the apical ring, which also sends forward, as in the preceding 

 segments, a lateral mark on either side. Segment 8 is black 

 dorsally, with a yellowish-green band either side, and beyond 

 these again black lateral lines. Segments 9-10 are black, 9 with 

 a small and 10 with a minute pair of yellowish spots. Under 

 surfaces yellowish brown. Appendages short, yellow, with black 

 tips. 



Length of abdomen 30 mm., of hind wing 24 mm. 



Several pairs from a stream near Kwala Aring. 



Legion Protoneura. 



Protosticta foersteri, sp. n. 



One female from Gunong Inas, Perak. 



Lower lip rounded, with short lobes. A small supplementary 

 basal postcostal nerve present, lying at a level between the base 

 of the wings and the first antenodal costal nerve. Pterostigma 

 trapezoid, dark brown in colour, surmounting a single cell, its 

 anterior margin shorter than its posterior ; followed by a single 

 row of cells. Sectors of the arculus united from their commence- 

 ment for a short distance. Upper sector of the quadrilateral 

 ending against the hind margin of the fore wing at the level of 

 the first postnodal costal nerve ; that of the hind wing one cell 

 lower. JVo trace of the loioer sector of the quadrilateral. The median 

 sector starts from the nodal vein, the subnodal a little beyond it. 



Head black ; upper lip and rhinarium blui.sh white, the former 

 with a black margin ; antennse yellowish.
