whole order of the Di])tera, of beiug different in the two sexes ; 

 tlie 6th vein in the S running straight to the wing-margin, 

 whereas in the 5 it turns np towards its tip, meeting the 5th vein

The species are mainly brown or yellowish in colour and small 

 in size, frequenting hedges, low-growing plants, shady nooks, 

 grassy iields, and similar situations.

 extends to North America and to the East, One species is known 

 from Rhodesia. 



Life-histonj unknown ; the larvae live in decomposing vegetable

Described from a S from Coonoor in the Pusa collectiou, 

 4. ix. 1911, " sweeping roadside " (Iloivhtt). 



In two specimens from Darjiling, 0900 ft., 29. v. 1910 {Bruneiti), 

 the back of the head is all yellow, though this character probably 

 has no importance. In one of the specimens the abdomen is 

 yellowish, in the other nearly as dark as in the Coonoor example. 



Thi? appears to be the L. lutea, Panz., of Europe and other 

 regions, though there are no specimens in good condition tor 

 comparison. Dr. de Meijere very kindly at my request sent 



* In a comprelieusive revision of the European species of this genus 

 Dr. de Meijere gives a full list of the varieties and references to this conmion 

 species. The accepted varieties are c'merca, Me]i.,Jlav/caiida, Mg., nitidifronx, 

 Strobl., pnlustris, Mg., and iriUnmta, Zelt., and 'the synonyms are numerous, 

 but are not repeated here in case the identification of the species should be 

 incorrect.
