in C. gonostigma, its common shaft slightly S-curved, about 

 IJ times or more as long as the fork. Fore branch of medial 

 vein moderately long. Areola postica moderately large, with 

 rounded fore margin, about one and a half times as wide as the 

 distance from medial vein. Anal vein not pubescent. 



Hind wings pale greyish, much paler than the fore pail*, 

 with a darker, brownish spot along fore margin in basal half, 

 and another one between base of radial sector and medial vein. 

 Basal part of radial sector about one and a half times as long as 

 the communication between this vein and media, and a little 

 shorter than the base of medial vein. Fore branch of radial 

 sector nearly perpendicular to the fore margin (the angle 

 distinctly more than 60°), hind branch almost parallel to the 

 fore margin, about as long as the fork shaft. Media slightly 

 S-curved. 



Length of body 2.0 nnn. ; of antennae 1.7 mm. ; fore wings 

 2.8 mm. long, 0.85 mm. wide.

This new species comes by the colour of wings and the shape 

 of pterostigma near to the Japanese C. trigonostigma Enderlein 

 and the Japanese C. gonostigma Enderlein. It differs from 

 both these species by the thick, short, dark antennae, 

 the much less numerous ctenidia of first iiind tarsal joint, and 

 by some details of wing venation. 



Caecilius jmjobergi n. sp. (Plate 3, fig. 5, beneath). 

 In general appearance very siuiiiar to the preceding species, 

 but somewhat larger and the coloration of fore wings more 

 distinct. (General colour dark, abdomen more yellowish-brown 

 (balsam slide ex alcohol). Maxillary palpi (fig. 5, beneath) 

 pale grey-brown, much paler than the body; apical joint 

 blackish at tip, about one and a half times as long as the 

 preceding joint, distinctly widened distad. Antennae (fig. 5, 

 beneath) longer and more slender than in C. borneensis ; the 

 two basal joints yellowish-brown, third and fourth somewhat 

 darker, the following ones dark grey-brown. Eyes similar as 

 in the preceding species, but larger and much more approxi- 

 mated to each other. Legs brownish-yellow, paler than body, 

 second tarsal joint and the tip of the first one dark grey- 

 brown. First joint of hind tarsi with 26 ctenidia, three and 

 a half times as long as the second one ; this latter without 

 ctenidia. Length of hind tarsal joints : I 0.45 mm., 

 II 0.13 mm.
