628 ON A NEW MOSQUITO. 



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

 segment formed of 10—12 simple hairs) arising from each of the 

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

 each with a short terminal haii'. 



Mr. Laurie supplied the following data regarding this mos- 

 quito : — " Mosquito larvse and piipse 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 water. The larvse 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, which I have much pleasure in dedicating to its 

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

 restricted sense ; it resembles 0. eaioni Edw. frofn the Madeira 

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

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

 related to the Asiatic group of species formed by the last-named 

 mosquito, 0. macfarlanei Edw., 0. pulcriventer Giles,, 0. oreophilus 

 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.
