which is also brown, with long concolorous hair; the palpi five- 

 jointed, alike, of the same length in both sexes, over twice the 

 length of the proboscis, brown, hairy, the longest hairs basally, 

 the terminal joint long and slender, the basal very short, while 

 the intermediate ones are of moderate length. The antennas in 

 the female are pale yellow, faintly infuscated distally, rather 

 short, the basal joint globular, the succeeding ones swollen at the 

 base, the two apical longest; a whorl of long hairs at the base of 

 each joint and some very short ones scattered between. The male 

 antennas are banded, yellow and brown, the plumes very long and 

 dense, and of a pale grayish yellow color. 



The dorsum of the thorax is creamy white anteriorly, pale 

 yellowish brown posteriorly, with three longitudinal buff colored 

 stripes, narrowly margined with brown ; the median divided lon- 

 gitudinally by a yellow line and terminated about one-third the 

 length of the thorax from the posterior margin; the lateral lines 

 begin at the posterior margin and extend forward to a little over 

 one-half the length of the thorax ; the pleura are creamy white or 

 pale yellow, with small black speckles sparsely scattered over the 

 surface. The legs are rather short, clothed with fine hair and pale 

 yellow, except the two last joints of the tarsi, which are grayish 

 brown. The claws are equal and simple on all feet of both male 

 and female and are rather short and stout. The wing veins are 

 covered with long, hair-like scales. 



The abdomen is pale buff colored above, sometimes brownish, 

 thickly covered with long concolorous hair, and with small black 

 speckles sparsely scattered at the sides and also on the dorsum 

 of the posterior segments ; beneath it is pale yellowish. 



Hahits of the Adult. 



Very little is known of the habits of this little fly, which, 

 though it is a true mosquito in essential structures, does not have 

 the mouth parts developed for biting. It has not been taken in 

 the ordinary collecting and is not, of course, to be classed as a 

 pestiferous form. It has been bred from early May to October, 

 mostly from the northern part of the State, but it also occurs at 

 Delair in Camden County and perhaps yet further south.
