Teucholabis.

Tab. 1, f. 12, wing; Tab. 3, f. 9, forceps. 
Since my article on this genus in the Monographs, where only 
american species are mentioned, its area has been extended to sou- 
thern Asia (T. bicolor O. S., Ann. Mus. Civ. Genoa XVI, p. 404; 
Sumatra) and New Guinea (Limnobia exclusa Walk. J. Proc. Linn. 
Soc. VII, p. 105). With the three species described below, the total 
number is now thirteen. 
A rather characteristic feature of Teucholabis, not mentioned 
by me before, is a slight expansion of the subcostal cell near the 
stigma, visible in most species; it also occurs in the closely allied 
genus Paratropesa. 
Teucholabis fenestrata n. sp. Dark brown, thorax fer- 
ruginous-red, shining, striped with black; wings brownish. subhyaline 
on the proximal half. Length 5—6 mm. 
Head, antennae and palpi black, front shining. Thorax ferrugi- 
nous-red shining, with black stripes; the intermediate stops before 
the collar, the lateral ones sometimes are indistinet; hind part of 
metanotum, and sides of pectus blackish. Abdomen, including the 
ö genitals, dark brown; ovipositor reddish-yellow; halteres 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 first vein and the hind margin; this hyaline space 
does not quite reach the central crossveins; 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 second and fourth veins, usually covering the cross- 
veins at the end of the discal cell. 
Hab. Ceylon; a & and a Q inMr. Bigot’s collection; also spe- 
cimens in the Museum in Leiden. 
Undoubtedly a Teucholabis, although of a somewhat different 
type than T. bicolor. The discal cell is comparatively smaller here, 
and much shorter than the 24 post. c., while in T. bicolor it is a 
little longer; the collar is a little less developed; the first longitu- 
dinal vein extends a little beyond the marginal crossvein; and the 
slight enlargement of the costal cell, near that crossvein, which exists 
in the typical species, is not visible here. 
Teucholabis determinata n. sp. ©. Thorax yellow, 
variegated with black; wings with a faint brown crossband and brown
