Phlebototnus himalayensis, Annandale. A yellowish grey species re- 

 sembling tninutus in general appearance, but distinctly larger and yel- 

 lower ; the w r ing is easily distinguished by the length of the anterior 

 branch of the second longitudinal vein. It is found in the Himalayas 

 between the altitudes of 4,000 and 7,000 feet, and is common during May, 

 June and July. 



Phlebototnus perturbans, Meijere. A dark brown species abundant in 

 the jungle hills at the base of the Eastern Himalayas ; it is also found 

 in Java. 



Phlebotomus minutus, Rondani. (P. babu, Annandale.) Probably the 

 same as the European form, but according to Annandale it is of a silvery 

 grey colour. It is the smallest of the Indian species, and can be distin- 

 guished from argentipes by its narrow wings and uniformly greyish 

 colour. It is widely distributed all over India, and is common in Ceylon ; 

 but is not found at high attitudes. In Madras it is common in June and 

 July, and sometimes in September, especially after small showers of rain, 

 but it entirely disappears during the south-west monsoon and is never 

 seen during the cold weather. 



Phlebotomus argentipes, Annandale and Brunetti. Thorax dark 

 brown or even blackish, sides yellowish, a character by which it can be
