REPORT OX MOSQUITOES. 361 



Lahaway was not put on the bog^s until October or November 

 and it is unlikely that the larvae hatched after that time. It is 

 equally unlikely that there was any oviposition by hibernating 

 adults early in March and the alternative seems to be a winter 

 egg hatching ^\'ith that of canadensis. 



CORETHRElvLA BRAKKLEYI, COQ. 



Brakclcy's Corcilira: 



This is the smallest mosquito occurring in the State. The 

 thorax is marked by four stripes, the median two edged with very 

 dark brown, which give the anterior part of the thorax a three- 

 striped appearance. The abdomen is unhanded, but has many 

 yello'W hairs scattered over the surface. The legs are hairy, the 

 tarsi yellow, the femora and tibiai brown, with dark shadings 

 near both ends of tibi^ and the apical end of the femora. The 

 wings are crossed by two blackish bands. 



Description of the Adult. 



This very small mosquito, which is shown on plate figure 114 

 with some structural details, measures 1.5-2 mm.,=.o6-.o8 

 of an inch in length. The head between the widely separated 

 eyes and the occiput is dark brown without markings, save for 

 a faint yellowish border to the eyes. The proboscis and palpi are 

 brown, the latter five- jointed and similar in form to the other 

 species of Corethra. The antenna in the female is very long and 

 pale yellow in color, with the basal joint brown, the base of each 

 joint succeeding the first which is very large and globular in 

 fomi, is elongate, swollen and set with very long bristles at the 

 base; other shorter hairs are scattered over the surface without 

 regularity. In the male the antenna is the same as the female in 

 size and color, but the hairs are long and very dense. 



The dorsum of the thorax is brown, marked with several large, 

 grayish confused spots, and two grayish median stripes, which 

 extend backward from the anterior margin to the middle, and 

 are margined with very dark brown, giving the thorax the ap- 

 pearance of having three stripes, two other grayish, longitudinal 

 stripes are on the basal half, one on each side. The pleura are 

 uniformly brown. The legs are covered with long hair. The 

 femora are brown, becoming very dark toward their apices, l)ut 

 are yellowish at the knee; the tibicT are dark brown, paler in the
