a lateral, semicircular one on the posterior half; hut this is seen onl}^ 

 in very fresh specimens. The pleura are almost wholly covered with 

 white scales. The femora are cream colored, becoming brown toward 

 the apex on the upper surface, then with a sharply defined creamy spot 

 at the knee; the tibia and tarsi are uniformly dark brown, save that 

 the former has yellowish bristles. The claws are equal in size on all 

 feet, each claw with a single median tooth. The abdomen is very dark 

 brown, with broad, clean-cut white bands at the base of the segments, 

 which become wide laterally; beneath it is whitish with intermixed 

 brown scales and a narrow, median brown stripe. 



Male. — The male is like the female in general appearance. The 

 antennge are brown with paler plumes, and the palpi are brown with- 

 out rings or marks. The claws of the anterior and mid tarsal joints 

 are unequal in size, the larger with a single median tooth, the smaller 

 with a single tooth near the base. The posterior claws are equal, each 

 with a single tooth near the middle as in the female. 



Desoription of the Larva. 



Dr. Dyar differentiates the larva from G. soUicitans (Proc. Ent. 

 Soc. Wash., vol. VI., p. 39), and figures it with some of the details 

 (Jour. N. Y. Ent. Soc, vol. XII.), but here gives no description. 

 His figures agree with those given subsequently by Dr. Felt (Bull. 

 79, N. Y. Sta. Mus.) under the name Culex abserratus, which is a 

 synonym of what Dr. Dyar calls C. punctor. 



As Dr. Felt says, the larva bears a general resemblance to C. 

 serratus. The antennse are rather stout, with the tuft at the basal 

 third. The mentum is rather broadly triangular, bearing twenty- 

 seven fine triangular teeth. The comb or scale patch on the sides of 

 the eighth abdominal segment consists of six or seven scales arranged 

 in a curve. The anal siphon is about three times as long as wide, with 

 a double posterior pecten or row of spines, each row consisting of 

 twelve to fifteen closely set spines. The anal gills are long, slender 

 and uniformly tapered. 



HahiU. 



From a lot of larvse and pupae collected in the woodland near 

 New Brunswick, April 28th, a male and four females emerged May 

 1st. No others hatched from this lot, but from another collection 

 made May 2d, two more females were secured from the pupae on the
