12 The Mosquitoes or Culicidae of Jamaica. 



GENEKAL ACCOUNT OF THE SPECIES 

 FOUND IN THE ISLAND. 



1. ANOPHELES PUNCTIPENNIS. Say. 

 (The Winter Mosquito.) 



(Journ. Acad. Nat. So., Philadelphia, III., 1823; Mono. Culicid. I., 

 p. 189, 1901.) 



General appearance. Head covered with black upright forked 

 scales, with a small patch of white ones in front. Palpi with 

 brown scales, a narrow grey band basally and a greyish tip with a 

 broader band between, banding seen only in some lights, in others 

 the palpi are all dark brown. Thorax deep chestnut-brown, with 

 a median broad patch of silvery-grey, covered with scanty pale 

 golden narrow curved scales. Abdomen dark, blackish-brown, 

 with scattered golden hairs, dull grey at the base of the segments 

 in some specimens. Legs brown, knees and tips of tibiae yellow, 

 wings with the costa almost black, with two yellow spots, one at 

 the apex, another on the apical third, which is large and prominent 

 and spreads as a band on to the wing field, most of the rest of the 

 wing dark-scaled, except for a yellow spot on the middle of each 

 branch of the second fork-cell and another in the middle of the 

 sixth long vein. 



Length. 5 mm. 



Geographical distribution. Abundant in the eastern United 

 States. It has occurred in Jamaica at Port Antonio (Professor 

 Johnson and Dr. Moseley), but is seemingly rare there. The 

 specimen sent me by Dr. Grabham was quite normal. It has 

 probably been introduced and does not appear to occur elsewhere 

 in the island. This is the only true Anopheles found in the West 

 Indies. 



Life-history and habits. The larva has a rounded brown 

 head; the mid frontal hairs are simple, the lateral branched. 

 Between the antennae are six plumose hairs, and between the 

 latter, nine more or less distinct pigmented spots, the largest in 

 the centre, the others arranged around it. Antenna of two 

 .segments, the first short and immovable, the second elongate and 

 bears two rather long spines and two short ones and a 6-branched
