APPENDIX. 



The following species also occurs in Jamaica. 



WYEOMYIA GRAYII. Theobald. 



Aedes perturbans. Williston (?). 



(Mono. Culicid. II., p. 269, 1901, and III., p. 310, 1903.) 



General description. Thorax testaceous brown, with dusky 

 scales ; pleurae ochraceous, densely clothed in parts with broad 

 white scales. Abdomen dusky black above ; venter ochraceous. 

 Legs black ; coxae and venter of the femora ochraceous ; ungues 

 of the female equal and simple ; metanotum with four chaetae 

 placed quadrangularly ; proboscis not quite as long as thorax 

 and abdomen. 



Observations. A delicate spider-like mosquito resembling 

 Dendromyia Mitchellii, Theobald, to which it is closely allied. 

 When settled it throws its hind legs right forward over its head. 

 It is a vicious biter. Found by Dr. Grabham in the Red Hills 

 and Bath Botanic Gardens. Nothing is known of the male or 

 larvae, all attempts to breed it in captivity having failed. 



Length. Body, 3 to 3'5 mm. ; hind legs 8*5 mm. 



NOTE ON GRABHAMIA JAMAICENSIS. Theobald. 



Dr. Grabham has lately bred this species, and notes the 

 following points. The ovum closely resembles that of G. pyymaea, 

 Theobald, differing only in the shape of the papillae, which are 

 pointed. The larvae of these two species are also much alike ; 

 in a number of full-grown specimens which were examined the 

 spines of the comb on the eighth segment were digitately three- 

 spined, with a number of intervening weaker bristles. The 

 spines of the pecten on the siphon were in two rows of three each. 

 In G. pygmaea each row contained four or live spines. No points 

 of specific importance were noted in the pupa.
