own length distant from the mid cross-vein ; fringe dark brown ; 

 hal teres testaceous, knob darkened. 



Length. — 5 to 5*5 mm. 



$ . Palpi brown, the last two segments nearly as long as 

 the antepenultimate, the penultimate slightly shorter than the 

 apical ; long brown hairs on each side of the last two segments 

 and on the apex of the antepenultimate on one side ; a narrow 

 pale band at the base of the last two segments and also near base 

 of the antepenultimate ; proboscis black with a narrow white 

 band at base of the apical half. More grey scales on the head 

 than in the J . Thorax, abdomen and legs as in the $ . Ungues 

 of fore and mid legs unequal, both uniserrated ; hind equal and 

 simple. 



Length. — 4 to 5*5 mm. 



Habitat. — Stanford University, California (Professor Kellogg) ; 

 Jamaica (Dr. Grabham) ; Benecia Barracks, California • Port 

 Duchesne, Utah ; Fort Logan, Colorado ; Fort Nisbrara, Nebraska ; 

 Fort Reno, Okla ; Texas ; Idaho : Huntingdon, Tennessee ; Fort 

 Missoula, Montana ; Hock Island, Illinois ; Fort Snelling, Minne- 

 sota ; Washington (Miss Ludlow). 



Time of capture. — September and October (Kellogg) ; June 

 (Grabham). 



Observations. — Described from a series sent me by ProL 

 Kellogg. A marked species bearing some resemblance to C. 

 taeniorhynchus, but has apical and basal leg banding, and with 

 lines and spots of white. It also has simple ungues in the $ y 

 and the $ palpi also differ. It is not nearly so compactly built. 

 The specimens show variation in regard to thoracic ornamentation 

 and leg markings. One 9 nas no signs of the two thoracic spots r 

 and the last hind tarsus of one is almost all white. In others it 

 is almost all dark coloured. Coquillett considers it his Culex 

 tar sali 's, but he does not refer to the marked leg ornamentation. 



The larva of C. helloggii. — Head bright testaceous ; eyes 

 black, a black band behind ; antennae black at the apex, 

 acuminate, ending in three long black spines and one very small 

 one : just above the junction of the dark and pale areas is a fan- 

 shaped set of hairs. Thoracic hairs as follows : the frontal band 

 composed of two large median triple hairs, a couple of small ones 

 next, then two single ones, followed by two triple ones outside ; 

 the next lateral area composed of two outer densely compound 

 groups, then on the inside a double and single hair ; third area 

 composed of two compound bunches. The siphon as long as the
