ATRIADOPS. CEYLONIA. 155 



by a cross-vein, 3rd closed ; discal cell sometimes narrowly 

 open ; * anal cell open. 



Range. The very few species known come from China, Brazil, 

 Ceylon, Sumatra, Java, and South and West Africa.

3 . Head with eyes contiguous for a short space ; frons pale 

 brownish grey, with greyish-white hairs ; antennae pale brownish 

 yellow. Thorax (?) blackish (discoloured, probably brownish in life), 

 sides with longer whitish-grey hairs. Abdomen brighter brown, 

 each segment towards hind border drawn up slightly, forming a 

 slight ridge ; anterior half of each segment with fine golden-grey 

 pubescence, which towards sides becomes longer, thicker, and 

 whiter, and laterally on the hind margin of each segment is some 

 long black pubescence. Wings dark brown, the darker parts 

 blackish, hind margin rather broadly greyish, except at extreme 

 wing-tip, at tips of lower prong of upper branch of 4th vein, tips 

 of both branches of 5th vein, two or three intermediate spots 

 situated rather close together, and at tips of anal and axillary 

 veins, at each of which is a small blackish-brown spot ; similar 

 dark spots occur on the distal side of the diagonal veins, at the 

 juncture of the veins, and larger ones at the forking of both 

 4th and 5th veins ; at the distal end of the 2nd basal cell is an 

 ill-defined clearer space, and a similar subtriangular one extending 

 from the 3rd vein just before it meets the 4th, which, inclining 

 distally and diagonally, nearly reaches the costa. Thoracic 

 squamse considerably developed, with long greyish fringe. 



Length, 8 mm. 



Re- described from a single cf in the Indian Museum from 

 Trincomali, Ceylon, 10. ix. 1909 (Col. Yerbury), presented by 

 Herr Lichtwardt, the species having been originally described 

 from Java. 



Genus CEYLONIA, Licht. 

 Ceylonia, Lichtwardt, Deut. Ent. Zeits. p. 646 (1909). 

 Genotype, Ceylonia magnifica, Licht. ; by original designation. 



Body robust, linear. Proboscis hidden by the long hair of the 

 face; palpi small, thin; f epistome pointed, as in Trichopsidea, 



* In Wandolleck's figure of A. macula, Wd. (1. c. p. 247, fig. 2), a Brazilian 

 species, the discal cell is prolonged narrowly to the wing-margin, remaining 

 open through the failure of the lower branch of the 4th vein to meet the lower 

 prong of the upper branch. The species seems abnormal, as the 2nd longi- 

 tudinal vein is either absent or the 3rd vein must be unforked. Also in the 

 basal angle of the last posterior cell is a very small quadrate additional cell. 



t I follow Lichtwardt in stating that the face has long hair, but I have not 

 noted this fact in describing my nivea. In any case in my type of that species 

 the palpi are perfectly obvious.
