reach to fork of median vein, and first and third forks are subequal. In male 

 genitalia the superior appendages have the tip very broad; the superior 

 median piece is extremely short.

HYDROPSYCHIDAE. 



AETHALOPTERA DYAKANA, sp. nov. 



TYPE. M. C. Z. 10,885. Borneo: Duson Timoc (Grabowsky). 



Pale greenish white; basal joints of antennae more red-brown, other joints 

 broadly annulate with brown. Wings greenish hyaline; fore wing with six 

 small dark spots; one on cross- vein connecting the anals, the next on cross- 

 vein from first anal to cubitus, one on base of connecting veinlet to median cell, 

 a small one at base of median cell and one on the radius obliquely above it, 

 one on the anastomosis, and scarcely visible one on veinlet above anastomosis 

 to the radius. The venation is similar to that of Indian specimens of A. 

 sexpunctata, but the relation of anal veins to arculus is very different (Plate 

 6, fig. 72), the median cell is larger, and the veinlet connecting the median 

 cell to the cubitus extends towards base of wing, instead of outwardly. 



Expanse 15 mm. 



AMPHIPSYCHE PARVA, sp. nov. 



TYPE. M. C. Z. 10,886. Borneo: Mindai (Grabowsky). 



Whitish; wings hyaline, with whitish veins; some of the antennal joints 

 very narrowly dark at tips; postantennal warts hemispherical (cf), not their 

 diameter apart. Venation of the male similar to that of A. proluta; the radius 

 is more strongly sinuate at stigma, the pedicel of the first fork is concave above, 

 and the vein behind it also a little curved; the median vein at base of median 

 cell runs obliquely upward before going straight back to wing-base. Differs 

 from the Javan A. meridiana (c? unknown) in the longer first fork, in the sessile 

 fourth fork, and in that the veinlet from median cell to the cubitus runs back- 

 ward, instead of outward, and in the course of median vein at base of median 

 cell.

Pale yellowish throughout; tips of antennal joints narrowly dark; wings 

 yellowish, each fore wing with five black spots, subequal in size. The most
