Original Description of 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. Coquillett 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 Culex lactator and C. coronator described below.) 



The following is an abstract of the table : 



1. Antennas 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

 Original Description 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. infine 

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

 Culex. All the indoctum are from Trinidad; all the infine from Santo Domingo. 

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