Genus Cellia. 109 



abdominal segments. These may be only faintly represented or 

 absent altogether. Occasionally a median dorsal band of brilliant 

 white pigment extends from the respiratory stigmata to the 

 thorax. Colour of adult larvae is usually bright green ; some- 

 times dull olive green or orange grey. 



The pupa. — A pair of large branching hairs spring from the 

 posterior of the first abdominal segment ; a pair of smaller 

 branched hairs on the third and fourth segments. The second 

 segment without these hairs. 



According to Dr. Low, the larval stage lasts from fifteen to 

 eighteen days and the pupal stage two days. 



Synonomy. — This species was described in a Mexican medical 

 publication a year before the issue of the first volume of this 

 work under the specific name cubensis, by Agramonte ; the name 

 albipes also by which it is generally known must sink, as 

 Coquillett has shown it to be the albimanus of Wiedemann. 



Economic importance. — The adults bite by night and day. 

 Dr. Low describes how great numbers came and bit him about 

 midday when sitting under a mango tree in British Guiana. 

 Dr. St. George Gray also wrote me that " when disturbed it will 

 bite at any time of the day or night." 



Not only does this species bite somewhat severely, but it acts 

 as the intermediate host for the parasite of malignant malaria, 

 and also for the development of Filaria noctuma. On the other 

 hand, it is inefficient for Filaria demarquaii.

Note. — -A series of this species was sent me for examination 

 from the National Museum, Budapest. It proves to be a Cellia, 

 and not a Myzomyia, as appeared from Donitz's description. 

 Blanchard erroneously places it in Nyssorhynchus.
