extremities of the marginal and submarginal cells, extends 

 across tlic anterior branch of the third longitudinal vein into 

 the upper part of the second subinaiginal cell, and has its 

 proximal margin nearly straight and at right angles to the 

 costa ; the length of the space separating the stigmatic 

 from the apical blotch, measured on the costa, varies in 

 different individuals from about 1 mm. to about 1*4 mm.; 

 the fork of the third longitudinal vein is suffused ^Tith sepia, 

 and the small se[)ia-colourcd spot so formed is sometimes 

 connected either with the apical blotch, or, in the first 

 posterior cell, with a forwardly directed prolongation from 

 the stigmatic blotch, or Mith both ; in addition to the fore- 

 going the proximal half of the first basal cell is occupied by 

 a faint, light sepia-eolourccl streak, sometimes indistinct; 

 in specimens in which the stigmatic blotch does not extend 

 beyond the third longitudinal vein, the veins at the distal 

 extremity of the discal cell are still often suffused with sepia; 

 veins mummy-brown, auxiliary vein paler, anterior transverse 

 vein and extreme base of third longitudinal vein usually 

 darker than remainder of veins. Squamce sepia-coloured. 

 Halteres : knobs seal-brown above, ochraceous-buff below ; 

 stalks buff, brownish at distal extremity. Leys buff or 

 ochraceous-bulf, distal extremities of both front femora and 

 front tibiic brown or brownish; front tarsi dark brown^ 

 proximal two-thirds of first joint paler, tips of middle and 

 hind tarsi dark brown. 



Madagascar: type and thirteen other specimens from 

 Andranolava, iMajunga Province, North-West Madagascar, 

 24. xi. 1907 (J. J. Lloyd) ; a fifteenth specimen, from same 

 locality and collector, 8.xi. 1907. 



AVith reference to this species the collector writes : — "^ A 

 very active fly ; bites like a mosquito. All the specimens 

 sent were taken at dusk.^^ 



Rhinomyza simplicicornis , sp. u. 



? . — Lengtli^(8 specimens) 6"75 to 82 mm. ; width of 

 head 2*4 to 3 mm. ; width of front at vertex 0*5 to just over 

 05 mm. ; length of proboscis 1*2 to l'2o mm. ; length of 

 wing G*25 to 7'4 mm. 



Small, thick-set species, with third joint of antenncB totally 

 devoid of an vpper branch, and icings ivithout coloured hands, 

 spots, or blotches, though with very conspicuous dark brown
