Obioinai, Description or Janthinosoma scholasticus Dyar & Knab, not Culex 

 SCHOLASTICUS Theobald: 

 Described from the Antilles. Our specimens are from Trinidad, taken by Mr. 

 Busck in rain water pools at Cedros, with the preceding species. We have accepted 

 this identification, although it is perhaps open to some doubt, as Mr. Coqulllett later 

 applied this same name (scholasticus) to a very different species, collected by the 

 junior author in Central America, which same species he had also named " secutor 

 Theob." Not, however, the true secutor Theob. of Jamaica, of which we have speci- 

 mens from Dr. Grabham. (See Oulex lactator and 0. coronator described below.) 



The following is an abstract of the table : 



1. Antennae long and prominent, longer than the head 2 



2. Anal segment short, shorter than wide 4 



4. Pecten teeth of the air tube with two reduced rounded branches

 Obiginal Descbiption of Janthinosoma indoctum : 



We propose this name for the larvae called "Janthinosoma scholasticus Theob." 

 (Journ. N. Y. Ent. Soc, xiv, 182, 1906.) The adults resemble closely those of J. inflne 

 Dyar & Knab, but differ in the ornamentation of the thorax. In inflne the thorax is 

 dark reddish brown with two white spots on the disk, two at the front margin, faint, 

 and whitish scales on the scutellum; in indoctum the thorax is dull brown with 

 yellowish and white scales forming diffuse patches. Scholasticus Theobald is a true 

 Oulex. All the indoctum are from Trinidad; all the inflne from Santo Domingo. 

 The locality " Trinidad " should be erased in our description of inflne.

Descbiption of Female, Male, and Labva of Psobophora cingulatus : 



Female. — Proboscis slender, subeylindrieal, Tiniform, labellae conically 

 tapered; vestiture of small black scales, a small ring of white ones at distal 

 third, its edges ill defined, tip of labellae grey ; setae small, black, curved, those on 

 labellae more prominently outstanding. Palpi short, stout, about one-fourth as 

 long as proboscis, black scaled, the tips white ; setae rather long, black. Antennae 

 slender, the joints subequal, rugose, pilose, black; second joint a little longer 

 than the others, pale basally; tori subspherical, with a cup-shaped apical ex- 

 cavation, blackish; hairs of whorls short, sparse, black. Clypeus elliptical, con- 

 vex, brown, nude. Eyes black. Occiput narrow, convex, dark brown, clothed 

 with narrow, curved silvery-whitish scales which about half cover the surface, 

 denser on ocular margin, and many long and slender, erect, forked black ones;
