end of the ovum. The air chambers are quite diiferent to those in Stegomyia 

 fasciata [Aedes calopvs] ova." The larvse hatched in two days, and were fully 

 grown in eight days. They are probably capable of more rapid growth under 

 natural conditions. We believe that under natural conditions the eggs are not 

 deposited upon the water, but as in the other species of the genus, upon the 

 ground. The larvae sent us by Dr. Grabham came from pools on the Spanish 

 Town road, near Kingston. We assume from the long anal gills that the larvae 

 occur in fresh water.

Also reported from Antigua (Theobald, Giles). 



We possess no specimens of Psorophora pygmcea from the island of Antigua, 

 which is the type locality for the names pygmcea and aniigucB. If the receipt 

 of specimens from that locality should prove that these are a distinct species, the 

 present form will be known as Psorophora nanus. With such closely allied and 

 variable species as those under consideration, it is impossible to tell from descrip- 

 tions whether the Antiguan form is the same as the one before us or not. 



The larva which we have described and figured was received from Dr. Grab- 

 ham in a mixed culture, and it is therefore possible that we have not correctly 

 identified it, although we think that it is correct. 



PSOROPHORA HARUSPICUS (Dyar & Knab). 



Aedes haruspicus Dyar & Knab, Proc. U. S. Nat. Mus., xxxv, 56, 1908. 

 Aedes haruspicus Theobald, Mon. Culic, v, 620, 1910. 



Omginal Description of Aedes haruspicus: 



Female. — Proboscis rather short, slender, brown-scaled, with a sprinkling of 

 lighter ones, a light ring near the middle; palpi dark-scaled; occiput clothed mostly 

 with whitish scales and with four quadrate patches of darker scales; mesonotum 

 bright brown-Bcaled, mottled with patches of white scales, these white scales densest 

 in the region before the scutellum; scutellum clothed with shining whitish scales; 

 scales of the pleura white; abdomen black-scaled above, with broad apical soiled 

 white bands on all but the last segment; beneath mottled, with dull whitish and 

 light brown scales, the segments becoming lighter apically, but without defined 

 bands; femora and tibiae black-scaled, with a sprinkling of lighter scales, a whitish 

 ring on each femur toward the apex; tarsi black, with white basal rings, becoming 

 successively narrower on each joint; wings broad, the scales on the veins black and 

 white, giving a mottled effect; claws simple. Length, 3.5 mm. 



Male. — The abdominal bands are clearer white and narrower than in the female; 

 otherwise the coloration is similar. 



Twenty-one specimens. Port Antonio, Jamaica, bred from the larvae in seaside 

 pools, November 15, 1906. (M. Grabham.) 



Type.— Cat. No. 11995, U. S. N. M. 



We expected that Doctor Grabham would himself describe this species, but after 

 the destruction of his collection by the earthquake he has requested us to describe 

 it from the specimens he had previously sent us. 



Description of Femau;, Male, and Larva of Psorophora haruspicus : 



Female. — Proboscis moderate, cylindrical, uniform, labellae conically tapered ; 

 vestiture of small black scales, a broad ring of white ones at middle, its edges 

 ill defined, some of the white scales scattered nearly to apex, tip of labellae gray, 

 setffi small, black, curved, those on labellae more prominently outstanding. 

 Palpi short, stout, about one-fourth as long as proboscis, black scaled, no white 

 scales at tip of last joint; setae rather long, black. Antennae rather short and
