tusely angularly produced, the apex pointed ; genital styles 

 straight along lower edge, pointed at apex which is outwardly 

 curved, a spine-like process situated on inner side near base. 



Length of body 3.6 mm. ; tegmen 4.8 mm. 



Habitat : Teloc Ayer. 



( 6 ) T. fitscorosfratits sp. nov. ( i 9 ) . 



Vertex slightly shorter than in croccns, making angle between 

 face and vertex slightly greater ; keels on face not so large. Head 

 and thorax dark yellow, facial keels, front of clypeus, margin of 

 tegulae, last labial joint fuscous ; abdomen dorsally dark, ven- 

 trally light ; tegmina hyaline, yellowish, a long triangular fuscous 

 mark in second radial and radio-apical cells, the distal portion of 

 last medial and two cubital veins fuscous, slightly fucous on base 

 of costa and along claval veins ; wings slightly fuscous, dark 

 veined. This species is near croccus, but the genitalia is distinct, 

 the genital claspers being slightly narrower and the apex of anal 

 segment rounded, with a large downward pointing spine on each 

 side near apex. 



Length of abdomen 3 mm. ; tegmen 4.6 mm. 



Habitat : Telok Ayer.

Facial keels fairly deep, perceptibly converging about middle. 

 Light yellow, facial keels, dorsum of abdomen and last lab'.al joint 

 fuscous ; a round black spot on metapleura ; tegmina vitreous, 

 claval and distal ends of cubital veins smoky ; wings smoky vi- 

 treous, dark-veined. Anal segment rounded at apex ; genital 

 styles slightly spatulate at end, rounded at apex. 



Length of body 2.5 mm. ; tegmen 3.8 mm.

 PI. I fig. 5. 



Head, pronotum, legs and abdomen testaceous, face (especially 

 keels ) fuscous ; abdomen dorsally blackish ; tegmina hyaline, 

 opaquely white through waxv secretion, a fuscous mark in apical 

 subcostal and first apical median cells. This species is very close 

 to the type of the genus (Icucoptcrus) , but the genitalia is very 

 distinct. A genital style of each is figured as that is the more 

 easily observed part of this structure, but the ])enis jircsents more 

 marked dififerences. 



Length of body 3 lum. ; tegmina 4 mm. 



Habitat : Teloc Ayer.
