Hemicaecilius nigroguttatus n. sp. (Plate 3, fig. 7). 



General colour dark grey-brown (balsam slide ex alcohol). 

 Apical joint of maxillary palpi black. Head and humeral 

 angles of thorax set with about 0.2 mm. long bristles, especially 

 the fore margin of head with very rough bristles. Antennae 

 slender, two-thirds as long as the fore wings ; the two basal 

 joints thick, nearly as dark as the body ; the following ones 

 very pale yellowish, set with long scrubby bristles (length of 

 bristles 0.15 mm.). Legs as dark as the body, middle part of 

 tibiae very slightly paler. First joint of hind tarsi with V2 

 ctenidia, second one without such. Length of hind tarsal 

 joints : I 0.25 mm., II 0.10 mm. Apical segments of abdomen 

 set with long bristle-hairs. 



Fore wings (fig. 7) almost three times as long as wide, 

 hyaline, with large blackish spots in the centres of cells and 

 along the margins, except the cell distad from pterostigma and 

 that distad from areola postica which are hyaline. All veins, 

 except the anal one, set with long, strong bristles; margins 

 of wing with two or three bristle rows. Communication 

 between radial sector and medial vein only a very little shorter 

 than the basal parts of these veins before it. Fork of radial 

 sector wide and short, its marginal distance between the 

 branches longer than the fore branch ; the common stem quite 

 straight, about twice as long as the fore branch. Medial vein 

 two-branched; its stem strongly curved (convex backwards), 

 more than twice as long as the fork ; this very small and 

 relatively wide. Areola postica small, with broadly rounded 

 fore margin, hardly ^^ider tban the distance from medial vein. 



Hind wings pale grey, with a hyaline stripe along the anal 

 vein. Margins set with long bristle-hairs, veins without such. 

 Basal part of medial vein more than twice as long as that of 

 radial sector ; communication between both these veins longer 

 than both their bases together. Media distad from com- 

 munication S-curved. Hind branch of radial sector about 

 as long as the fork-shaft, fore branch scarcely half as long, 

 not quite perpendicular to the fore margin. 



Length of bod}' 3.0 mm. ; of antennae 1.9 mm. ; fore wing 

 3.0 mm. long, 1.1 mm. wide. 



One specimen from Mt. Dulit, 3000 feet, January, at 

 night (light), coll. Dr. E. Mjoberg. 



This new species comes by the two-branched medial vein of 

 fore wings to the genus Hemicaecilius, and differs from all the 

 hitherto known species of this genus by the strongly blackish
