 bearing several long stout spines. " Harpes small, somewhat 

 inflated near the middle, and tapering to three stout spines. 

 Harpogones divided, composed of two stout, recurved, chitinous 

 processes, the posterior limb larger than the anterior (E. P. Felt). 5 ' 



Length. — 5 to 5 • 5 mm. 



$ . Similar to the male in thoracic and abdominal adornment. 



Ungues equal and simple on all the legs. Palpi a little more 

 than one- third the length of the proboscis, composed of three 

 segments, two basal ones, long and slender apical one very small, 

 clothed with black scales and a few white ones, apex white. 

 Antennae black, with a few white scales. 



Length. — 5 to 5*5 mm. 



Habitat. — Delair. Camden County; Chester, Morris County ; 

 Lahaway, Ocean County, New Jersey (Prof. J. B. Smith) ; 

 Benecia, California (Miss Ludlow) ; Mississippi State (Professor 

 Glenn-Herrick). 



Observations. — Originally described by Coquillett as a Culex. 

 It is redescribed here from specimens sent me by Miss Ludlow. It 

 has been placed in the genus founded by Dr. Dyar, but it is merely 

 a bare name as no generic characters are given of any value, the 

 name has been adopted to save confusion in synonomy. 



Nothing is known of the habits of the adult. 



Description of the larva. — The larva has been described by 

 Professor J. B. Smith. 



It reaches 7-8 mm. in length ; greyish-black in colour, thorax 

 lighter ; head purplish-black, as long as broad. Six equally 

 placed hair-tufts of five or six hairs each are in a transverse row on 

 the anterior part of the vertex. Antennae short, dilated at the 

 basal third, tapering towards the tip, apex with two long spines, 

 two smaller ones and a small peg. Surface nude, hair-tufts on 

 the shaft a little over one-fourth from the base, composed of six 

 feathered hairs. 



Labial plate equilateral, with a large apical tooth, then five 

 or six small lateral ones, blunt at the tips, and four very large 

 pointed ones below, usually nine teeth on each side of the apex, 

 but now and then ten. 



Lateral combs consist of two rows of scales ; the first with 

 from fifteen to twenty-one greatly elongated ones, fringed laterally 

 at the basal half with fine hair, the longest scales towards the 

 base ; the second with six or seven scales, their apices extending 

 between those of the anterior row. The individual scales of the
