TEUCHOLABIS. 429 



310. Teucholabis fenestrata, Os. Sac. (PI. VIII, fig. 14; PI. XI, 

 fig. 10.) 



Teucholabis fenestrata, Osten Sacken, Berl. Ent. Zeits. xxxi, p. 188, 

 6 $ (1887). 



"Dark brown, thorax ferruginous red, shining, striped with black ; 

 wings brownish, subhyaline on the proximal half. Length 5-6 mm. 



" Head, antennae and palpi black, front shining. Thorax 

 ferruginous red, shining, with black stripes ; the intermediate 

 stops before the collar, the lateral ones sometimes are indistinct ; 

 hind part of inetanotum, and sides of pectus blackish. Abdomen, 

 including the male genitals, dark brown ; ovipositor reddish 

 yellow ; halterea brown ; legs, including coxae, dark brown or 

 black, hairy, rather stout. Wings tinged with brown, except a 

 large subhyaline space on the proximal half, between the 1st vein 

 and the hind margin ; this hyaline space does not quite reach the 

 central cross-veins ; and it touches the hind margin only between 

 the root and the anal angle; a second, much smaller, hyaline spot, 

 ill-defined in outline, on the distal half of the wing, between the 

 2nd and 4th veins, usually covering the cross-veins at the end of 

 the discal cell 



"Hab. Ceylon; a male and a female in Mr. Bigot's collection ; 

 also specimens in the Museum at Leiden. 



" Undoubtedly a Teucliolabis, although of a somewhat different 

 type than T. bicolor. The distal cell is comparatively smaller 

 here, and much shorter than the 2nd posterior cell, while in 

 T. bicolor it is a little longer ; the collare is a little less developed ; 

 the 1st longitudinal vein extends a little beyond the marginal 

 cross-vein ; and the slight enlargement of the costal cell, near that 

 cross-vein, which exists in the typical species, is not visible here." 

 (Osten Sacken.) 



From an examination of a good series of males and one or two 

 females in the Indian Museum, the following notes may be 

 appended to Osten Sacken's description. 



The dorsum of the thorax is more often wholly ferruginous 

 than otherwise, a distinct stripe, much less three, being apparently 

 the exception, although there are not infrequently indistinct 

 brown suffusions in parts. The legs are sometimes dark yellowish 

 brown, the coxa? occasionally reddish yellow, and the subhyaline 

 spaces in the wings are mostly indistinct or absent. 



The Indian Museum has it from Kurseong, 3. vii. 08 (Annan- 

 dale) ; Naini Tal, 14-17. iv. 07 ; Khasi Hills, Assam ; Mazbat, 

 Mangaldai district, Assam, 11-15. x. 10 (Kemp)-, Peracleniya, 

 Ceylon, 26. vii. 10 (Gravely), one of the very few females seen by 

 me. It is in the Pusa collection from .Darjiling, 3-9. vi. 09 

 (Howleti), and the Khasi Hills ; whilst it figures in Mr. Green's 

 collection from Ceylon, where it is common, the males hovering in 

 small clusters under trees overhanging roads.
