90 MR. F. F. LAIDLAW ON THK [Feb. 4, 



under surface yellow, the yellow extends for a short way on to 

 the sides. Abdomen black, mid-dorsal carina orange, a yellow 

 spot on either side of first segment. Segments 2-4 have on 

 either side a yellow line followed by a yellow dot. Wings 

 hyaline. 



Antenodals 11-14. 



This species is closely allied to R. jjerforata, but differs from 

 that species and its other allies in the greater extent of the 

 purple mark on the fore wings of the male. The marks of 

 the hind wing resemble most closely those of H. whiteheadi Kirby. 



Seven males, four females, Gunong Inas. 



Rhinooypha karschi Krliger, Stett. ent. Zeit. 1898, p. 33. 



Three males from the Aring River near Kwala Aring. 



Abdomen, length without appendages 14" 15 mm. 



Hind wings 20 ,, 



A single row of postcostal cells. Fore wings yellowish hyaline, 

 hind wings with a blackish-brown mark covering their outer 

 extremities starting about halfway between the nodus and ptero- 

 stigma, its inner margin convex. No vitreous spots on the wings. 

 The abdomen has on its dorsal side a brick-red spot on segments 

 2-6 ; that on segment 2 is small and oval, from 3-6 the spots 

 are large and rectangular, the sides of the rectangle are longer 

 than the ends. On segment 7 are two long red lines divided by 

 a fine mid-dorsal black line, and on segment 8 two very small red 

 spots similai'ly divided. In one case the spot on segment 6 is 

 also divided by a black line. The sides of segments 1-8 have 

 each a yellow comma-shaped mark. 



Krliger points out that this species belongs to a group inter- 

 mediate in character between B. heterostigma and R. tincta of 

 de Selys. Described by Kriiger from specimens from Sumatra.

 along the dorsal posterior margin, ending laterally in a spot of the 

 same colour just above the base of the first pair of legs. 



Thorax black, a small antehumeral stripe on either side not 

 reaching to the top of the mesothorax, and a fine line on the 

 upper half of the humeral suture also yellow. At the sides are 

 two large oblique yellow bars ; the anteiior of these is divided 

 into two halves by a black mark projecting into it fi'om its hinder
