NOTES ON SOME NEW MOSQUITOES FROAE JAMAICA, WEST 



INDIES. 



BY M. GRAPiHAM, KINGSTON, JAMAICA. 



The following are brief notices of three new species of mosquitoes, 

 full accounts of which will be published in tlie second edition of " The 

 Mosquitoes or Culicidje of Jamaica," now in course of preparation. 



yEdes nncattis, n. sp. — Close to Stegomyia mediovittata. Coq., from 

 Santo Domingo (Can. Ent., Feb., 1906, p. 60). but the subdorsal thoracic 

 lines are made up of light yellow scales throughout their wlTt)le length. 

 Full-grown larva with six or seven separate comb scales, each scale with 

 a simple stout curved spine arising from a pear-shaped base. (Fig. i.) 

 The larvfe of this form, collected from hollow trees, 

 have been sent to me from several localities near 

 Kingston (Waverley Estate, Constant Spring: woods above 

 Rockfort). In all the specimens examined the comb scales 

 had simple spines unlike the Santo Domingan form, which 

 from'^co'mbo^.^d'es ^as trifid spines (Dyar and Knab, Jour. N. Y. Ent. Soc, 

 uncatus. ^IV, PI. V, flg. ii). I am indebted to Dr. H. G. Dyar 



for comparing the larvae and adults of these two species. Bred specimens 

 vary greatly in size, the largest attaining about 6 mm. in length. The 

 females bite blood without hesitation. 



Mansonia Waverleyi, n. sp. — Close to M. signifer, Coq., but with an 

 additional curved line of white scales on each side of the mesothorax. 

 (Fig. 2.) T\\\% line is usually somewhat broken. I am likewise indebted 

 to Dr. Dyar for examining the larvte and adults of this 

 species ; he writes that the larvae also differ in the 

 arrangement of the abdominal plates. The larv?e were 

 collected from thick coffee-like water found in hollovv mango 

 trees at Waverley Estate, Constant Spring, Jamaica. They 

 are grayish-white in colour, and appear to be peculiarly 

 inactive, lying at the bottom of the jar for long intervals. 

 The pupa stage lasted five days. Length of adult 5.5 mm. ack^"lirn^'^ntal 

 Howardina inceqiialis, n. sp. — Near H. atireostriata, waverkyr""'"^ 

 Gbm. (Can. Ent., May, 1906), but with somewhat broader 

 thoracic lines. The face hairs of the larva are as follows: Anteantennal 

 hair 5- to 8-rayed, upper epistomal hair double, lower about lo-rayed. 

 The compound hair of the dorsal group in the terminal segment is about
