James and Listen regard elegans James, {loc. cit.) as a variety 

 of this species. However, Theobald considers elegans a vahd species.

" Described by me in Pr, Roy, vSo, Lond., Ixix, 378 9 as 

 christophersi from 2 9 9 sent to that Society by Drs. Christophers 

 and Stephens, but just previously described as Giles's ' Listoni ' by 

 Capt. Liston." (Theob. Mon. Culic, iii, 28.) 



The species is very near culicifacies Giles, and jeyporensis James. 



Aitken has studied the larva {vide Theob, Monog. iii, 29) 

 which occurs in rice fields and small rocky streams, but abounds 

 most in boggy ground near rice fields. 



James and Liston report the larva from clear streamlets with 

 grassy edges, and state definitely that the species is a malaria carrier 

 as proved both by experiment and under natural conditions. 



Messrs. Alcock and Adie, in the Proc. Roy. So. Lond., Ixxvi, 

 319, give a short, interesting account of breeding this species 

 from larvae (collected 7-11-1905) from the Indian Museum tank. 

 They bred 7 adults from 26 larvae, the remaining 12 larvae (placed 

 in a separate vessel) being voraciously devoured by the larva of a 

 very common oriental dragon fly {Ceriagrion coroniandelianum). The 

 existence of Listoni in Calcutta is important, owing to the malaria- 

 carrying powers of this insect. The Malaria Commission found the 

 species absent during their investigations in June, July and August, 

 and attributed the absence of malaria from Calcutta, to the absence 

 during those months of known malaria carriers. Messrs. Alcock 

 and Adie, taking it in December and January (no adults were found 

 in February), will make it desirable for the species to be searched 

 for diligently by other observers.
