0.049 mm and 0.049 mm by 0.042 mm. Genital sclerotization as in 

 figure 4 If. 



Male. — Length of wing 1.19 mm. 



Similar to the female with the usual sexual differences; antennal 

 plume yellowish; leg and abdominal markings as in female; thoracic 

 pattern more distinct, as in punctifemorata; claws as in the female, 

 tarsomere V with 2 batonnets on each leg. Genitalia (fig. 41^r — i) 

 yellowish, parameres and apices of basistyles dark brown; sternum 

 IX with very faint, low caudomedian excavation, spiculation very 

 faint; tergum IX rounded with strongly pubescent, elongate caudo- 

 median lobes; basistyle short, mediangular process poorly developed, 

 the faintly sclerotized platelike mesal lobe elongate; dististyle very 

 long, as long as basistyle, only slightly narrowed toward the bluntly 

 pointed tip; aedeagal sclerites forming a high arch, height greater 

 than basal breadth; basal portion of each nearly straight, narrow at 

 base, gradually broadening distally past midsection, with tip abruptly 

 constricted and bent ventrolaterad in a slender, curved point; para- 

 meres each with broad basal arm extending laterad; main portion 

 long and slender, nearly straight, extreme tip abruptly bent ventrad 

 and narrowed. 



Distribution. — Malaya; North Borneo. 



Types. — Holotype male, Kuala Singgora, Pahang, Malaya, 18 July 

 1958, R. H. Wharton, light trap (USNM 69443). Allotype female, 

 Labuan Island, North Borneo, Sept.-Oct. 1948, D. H. Colless, at 

 light. 



Discussion. — This species is the only known Oriental Eukraiohelea 

 with the hind femur entirely pale; it differs from the other Oriental 

 species and resembles the African foyi (Ingram and Macfie) in the 

 L-shaped dark bands on abdomen. The elongate, blunt- tipped dis- 

 tistyles and the shapes of the aedeagal sclerites and parameres are 

 also distinctive. 



2. Stilobezzia (Eukraiohelea) fuscipes Das Gupta and Wirth, new species 



Figures 39, 42 



Female. — Length of wing 1.18 (1.15-1.24, n=10) mm; breadth 

 0.48 (0.46-0.49, n=10) mm. 



Closely resembling fusciterga, new species, and punctifemorata, 

 new species, with the following distinctions: A smaller species, with 

 dark markings of thorax, legs, and abdomen more intense and ex- 

 tensive; hind femur (fig. 42a) brownish from near base, the color 

 intensely dark brown on distal fifth; wings more deeply infuscated. 

 Antennomeres III-XV (fig. 39) with lengths as 12-8-8-8-8-8-8-8- 

 19-20-20-20-39; antennal ratio 1.74; palpal segment III with sensory 

 pit almost apical; mandible with 6-7 teeth; wing (fig. 426) with cross-
