Description. This larva has rather stout, dark tipped antennae 

 with the tuft at the middle. Labial plate triangular with 21 or 23 

 teeth. The comb consists according to Dr Smith of 16 to 24 some- 

 what spatulate scales bearing a row of coarse setae, the longer 

 ones at the apex. The air tube is very short, about one and one 

 fourth times as long as broad with about 15 closely set pecten 

 teeth with three to six or seven minute sierrations on each side. 



Dr Dyar states that the larva differs from C. sollicitans, 

 by its shorter tube and the differently shaped teeth of the lateral 

 comb. 



Distribution. This appears to be a widely distributed form, 

 since it has been recorded by Theobald from New Amster'dam, 

 British Guiana, St Lucia, Florida, Honduras and Brazil, and it 

 also occurs rather commonly in New York and New Jersey. 



Life history and habits. This species probably passes the winter 

 in the egg stage, in mud or at the base of grasses, in the same 

 manner as C. sollicitans, since Dr Smith has bred it from 

 eggs in the same piece of sod, and he states that the two species, 

 have the same habits, having reared adults of both, without pre- 

 viously suspecting that he was dealing with two inisects. 



Culex confinis Arrib. 

 This species has been listed from New Jersey by Dr Smith, who- 

 took it at Delair, July 10, and at New Brunswick, Aug. 3. It 

 very probably occurs in New York State, and the following de- 

 scription by Theobald should prove of service in its recognition. 



Very like Taeniorhynchuis taeniorhynchus Arri- 

 halzaga but of smaller size and darker color, while the band on 

 the proboscis is broader, but differs especially in the form of the 

 wing scales. The broad white proboscis band extends from near 

 the base to the middle; legs fuscous, fore femora sparsely decor- 

 ated with scattered white scales, with a narrow white band a little 

 before the apex; tibiae speckled white externally, uniformly 

 colored inside ; knees white ; fore and mid tarsi with the first three,^ 

 and the hinder with four, or all the joints with basal white bands ; 

 metatarsi distinctly shorter than tibiae. Abdomen dark fuscous, 

 with coffeeHColored scales above and narrow whitish bands ; gray- 

 ish below. 



Length, 4.5 to 5 mm. 



Habitat, Chaco in Formosa, Argenttna.
