ON A NEW MOSQUITO. 



in addition, with a short compound hair (that on tlie eighth 

 segment formed of 10-12 simple liairs) arising from each of the 

 dorso-antero-lateral angles. Paddles (text-fig. 3 b) large, ovoid, 

 each with a short terminal hair. 



Mr. Laurie supplied the following data regarding this mos- 

 quito : — " Mosquito larvae and pupse from a hollow in a fallen 

 tree-trunk. Sea-level. The hollow was about 12 ins. x 4 ins. 

 and 4 ins. deep, and contained w^ater. The larva3 and pupae were 

 removed and kept in captivity (7. 14), and two adults emerged 

 (a male on 18. 7. 14 and a female on 21. 7. 14) before we left the 

 Island." 



This species, wdiich I have much pleasure in dedicating to its 

 collector, is a member of the genus Ochlerotatus in the most 

 restricted sense ; it resem.bles 0. eatoni Edw. from the Madeira 

 Is., in regard to the length of the male palpi. In general facies 

 it somewhat resembles 0. japonicus Theo., and apparently is 

 i-elated to the Asiatic group of species formed by the last-named 

 mosquito, 0. macfarlanei Edw., 0. 2mlcriventer GileS; 0. oreopkilus 

 Edw., etc. 



Five examples of a second and probably undescribed species of 

 Ochlerotatus were also captured by Mr. Laurie in a dwelling-house 

 on the island. This species is dull brown in colour, and, with 

 the exception of yellowish lateral abdominal spots, is devoid of 

 ornamentation. Unfortunately, the specimens obtained were all 

 females, and therefore until more material is available it is 

 advisable to refrain from attempting an exact diagnosis.
