72 COPEOGNATHA FROM NORTHERN SARAWAK. 



Length of hind tarsal joints : I 0.24 mm., II 0.21 mm. 



Fore wings more than three times as long as wide, on the 

 veins and on whole surface set with strong bristles (fig. 6) ; 

 those on margins m two or three rows. General colour brown, 

 with greyish hyaline stripes in the costal and radial cell (this 

 latter except the apical part) and along anal vein, at its end 

 widened to a larger spot ; further a greyish hyaline spot at basal 

 part of pterostigma and in the neighbouring part of cell Rl, 

 from here produced as an irregular stripe till the base of areola 

 postica. Finally, the space from fork of radial sector till the 

 base of the branch of medial vein also greyish hyaline. 

 Distal part of pterostigma very dark brown. Hind margin 

 of pterostigma backwards produced almost rectangularly. 

 Communication of radial sector and medial vein shorter than 

 the base of radial sector before it, and this shorter than the 

 basal part of media. Fork of radial sector somewhat narrow, 

 much shorter than the common shaft, which is very slightly 

 S-curved. Areola postica broadly rounded, but not angulately 

 produced as in Dasypsocus, about twice as wide as the 

 distance from media ; its distal margin almost perpendicular 

 to the hind margin of wing. 



Hind wings greyish, darker along fore margin in basal half, 

 then nearly hyaline along fore margin till the end of radial 

 vein, then dark again in surrounding of the fore branch of 

 radial sector. Basal part of radial sector before the com- 

 munication with media about half as long as the base of 

 medial vein, this as long as the communication. Hind branch 

 of radial sector about as long as the shaft, twice as long as 

 the fore branch ; this slightly curved (concave basad) arising 

 in an angle of about 60°, ending at the fore margin almost 

 perpendicularly. Medial and cubital vein slightly S-curved, 

 the latter less than the former. 



Length of body 2.2 mm. ; of antennae 1.7 mm. ; fore wing 

 2.5 mm. long, 0.7 mm. wide. 



One specimen from Mt. Miirud. 7200 feet, coll. Dr. E. 

 Mjoberg. 



Differing from the hitherto known Kolbia species by the 

 spotted fore wings ; from Dasypsocus by the shape of areola 

 postica, from Ophiodopelma by the much less S-curved 

 fork-shaft of radial sector, from Caecilius by the strong bristles 

 on veins and on the whole surface of fore wings.
