 base, the hind pair with the npical h?lf black; tibia ochreous, 

 the hind witli the tips broadly black ; front and middle tarsi 

 brownish , hind tarsi black ; first segment of front tarsi nearly 

 twice as long as the tibia. Wings yellowish-tinged, with a 

 brown pattern as shown in the figure. Halteres yellow.

Mt. Miirud, 7000 feet, October— 1 (f • 



No very near ally of this species has been described, bnt a 

 rather similar West African form is represented in the British 

 Mnsenm collection. L. aftintica White (Ceylon) is a much 

 smaller species with unmarked wings. 



ExECHTA PALLiDULA sp. n. (Plate 10, fig. 24. 25.) 



Hrnd lirorsnisb ocbreons. fai^e pale ochreons. Antennae 

 uniformly brownish ochreous, palpi lighter. Thorax uniformly 

 brownish ochreous. Scutellum with two strong black bristles 

 and two smaller ones between them. Ahdomen with the 

 first tergite dark brown, its posterior border pale ochreous; 

 tergites 2-4 in the cf entirely ochreons ; in the 9 tergite 2 

 ochreons with a dark brown median stripe wliich is widened 

 in the middle and at the tip. tere"ite 3 ochreous. tergite 4 black- 

 ish, tergite 5 ochreons, with the hind margin dark; tergites 6 

 ~7 in the cf dark brown, in the O blackish. Hypopygium as 

 figured ; ovipositor constructed almost exactly as in E. pallida 

 Stan. Ijeqfi o-^hreous. tarsi darkened ; tibial spines black, 

 rather long. Winqs with a slight yellowish tinge ; Es very 

 slightly curved down at the tip ; r — m about three times as long 

 as the medinn fork; tips of Jlf, and M^ not reaching the wing- 

 margin; fork of Cn well beyond the base of Rs : Ax long and 

 straio-ht, almost reaching the margin. Halteres whitish, base 

 of knob darkened. 



Length of body 4.5 mm. ; wing 4 mm. 



Mt. Mnrnd foot, Octol-ter — 1 (;j* 1 9 in copula. 



This is very closely alHed to the European E. pallida Stan!, 

 even the hypopygial structure being very similar. There 

 appear, however, to be several nearly allied Oriental species of 

 this group; such are E. hasilinea Brnn. and E. flava White. 

 The best distinction between these species is perhaps to be 

 fpund in the shape of the large eighth sternite of the male.
