the early part of September. According to Marett it has the same breed- 

 ing habits as mimitiis. 



Phlebotomus papatasi, Scopoli (Plate XXXIII, figs. 2 and 4). A pale 

 yellowish grey species, sometimes with a dark coloured fringe to the costa 

 and the hind margin of the wing. The external genitalia of the male 

 are much larger than those of any of the other Maltese species, as can be 

 readily seen with the aid of a hand lens. The wing is narrower, but 

 the posterior margin is more distinctly arched than the anterior. It is 

 larger than its near ally perniciosus, paler in colour, and has longer legs. 

 This species is known to transmit the parasite (?) of Phlebotomus Fever. 

 It is widely distributed in Southern Europe, North Africa, and the whole 

 of North India. According to Marett in Malta, it breeds in caves and 

 embankments. 



Annandale and Brunetti's Key to the Indian and Cingalese species 



1. The second longitudinal vein forks nearer the middle of the 



wing than at one-fourth. Petiole of first submarginal cell 

 always much longer than one-third of the cell's length, except 

 in himalayensis, in which it forks exactly at one-third . . . 2 

 The second longitudinal vein forks exactly at one-third of the 

 wing. Petiole of first submarginal cell only one-third as long 

 as the cell ............. 8 



2. Tip of first longitudinal vein, either about half-way between 



fork of second vein and tip of wing, or nearer tip of wing. ... 8 



Tip of first longitudinal vein distinctly nearer fork of second 



vein than tip of wing ........... 3 



3. Fork of upper branch of second longitudinal vein nearer fork 



of second vein than tip of first vein. Wing comparatively 

 lanceolate ; fork of second vein beyond that of fourth vein. 

 Colour of insect yellowish grey. Genitalia of male with 



three chaetae at tip himalayensis. 



Fork of upper branch of second longitudinal vein nearer tip of 



first longitudinal vein than fork of second vein ...... 4 



4. Wing broader ; fork of second vein before that of fourth vein. 



Colour of insect dark greyish brown. Genitalia of male with 

 both the middle chaetae median. Hind femur between one- 

 half and three-quarters as long as its tibiae, and distinctly 

 longer than the metatarsus, which is shorter than the rest of 



the tarsus. Length 2\ mm. perturbans. 



Wing lanceolate ; fork of second vein and that of fourth vein 

 practically opposite one another. Colour of insect silver 

 grey. Genitalia of male with the middle chaetae subapical. 

 Hind femur nearly as long as its tibia, more than twice the 

 length of the metatarsus, which is shorter than the rest of 

 the tarsus. Length 1| mm. ....... minutus. 



5. Fork of upper branch of second longitudinal vein barely before 



tip of first longitudinal vein (not a reliable character). Sides 

 of thorax conspicuously paler than the dark dorsum. Genita- 

 lia of male with two chaetae at tip and three median ones.
