spots in the anterior portion. The pleura are black with small 

 patches of grayish scales. The femora are black with scattered 

 yellow scales ; the apex is white and there is a broad white band 

 near the apex on the posterior femora, a narrower band on the 

 anterior, and almost none on the median pair. Beneath they 

 are wholly yellowish. The tibise are black with a white dot at 

 the base and many white scales collected into spots on one side. 

 The tarsi are black with broad white rings at the base of all 

 joints except the fifth on the fore and mid feet. The first tarsal 

 joint has. in addition, a broad white band in the center, less dis- 

 tinct on the mid and anterior pairs. The claws of the fore and 

 mid tarsal joints of the male are unequal in length, the large;- 

 with a median and basal tooth, the smaller with a basal tooth 

 only. The posterior claws are equal and simple as are all those 

 of the female. The wings are hyaline with the veins clothed with 

 mixed black and white scales ; at the base of radio 4+53. small 

 portion has no white scales, making a distinct black spot. 



The abdomen is jet black, the first segment with a patch of 

 yellowish white scales in the center of the apical margin ; the sec- 

 ond banded with the scales prolonged forward in the middle ; the 

 following segments with two C-shaped marks, back to back, but 

 divided by the black. These marks are sometimes diffused or 

 become less curved posteriorly, until the apical segments have 

 two longitudinal marks. Beneath it is brownish or slate colored.

Habits of the Adult. 



Though this is scarcely to be considered a rare mosquito, it 

 seems to be very local, and as an adult does not seem to get away 

 from the immediate vicinity of its breeding pools. It has never 

 been sent in by any of my correspondents and none of the col- 

 lectors have taken it in the collections made to determine what 

 species were flying. Although a lively breeding place is only a 

 few hundred feet from my house, the species has never made its 

 appearance on my porch. Adults could be collected easily 

 enough in the immediate vicinity of the pools, but none were 

 seen only a few feet away. 



The female has fully developed mouth structures and may bite, 

 though she is not aggressive. Mr. Grossbeck reports being bit- 

 ten by one specimen, and says that the bite does not hurt at all at 

 the time, but that the swelling and the pain develop soon after- 

 ward. 



So far, material has been received onlv from Delair through 

 Mr Seal, and from New Brunswick through office collections. It
