770 MOSQUITOES OF NORTH AMERICA 



" Previous to that, on May 29th, while one of the reservoirs was yet water 

 covered a very careful examination was made and all the places where larvae 

 were earlier taken were tested without result so far as obtaining larvse was 



concerned. 



" Practically all our knowledge of this species comes from Mr. Brakeley's 

 observations, though in 1904 Mr. Grossbeck took larvae in the Great Piece 

 Meadow, May 10th, from which a male adult was obtained May 13th, as against 

 a dozen canadensis which emerged on the same date. Mr. Brehme, in collections 

 of larvffi and pupae made at Arlington, May 9th, also had one male of this species, 

 which emerged May 13th. This indicates a somewhat general distribution in the 

 State [New Jersey], but a rare occurrence at any point. No one save Mr. 

 Brakeley has taken the adults in New Jersey, and all who have taken the larva 

 have found it associated with that of canadensis.

" In 1903 Mr. Brakeley sent in the first larvae, March 23d, as extra large canor 

 densis. Being advised of the difference, he found them afterwards in the larger 

 bodies of water covering the bogs and reservoirs and in pools of considerable 

 size nearby, always associated with canadensis and always comparatively rare. 

 They do not hug the edge of the pool so generally as do some of the other species, 

 but favor tufts of grass, rushes or vines several feet from shore. Larvae only 

 were collected until April 14th, at which time the tirst pupa was taken. There- 

 after larvae and pupae were taken until well along in May, the latest actual date 

 at which either larvae or pupae occurred being May 13th. No aurifer larvae have 

 been collected with the earliest canadensis, and from such data as I have at hand 

 it seems that the eggs begin to hatch during the early days of March and that the 

 larvae grow quite rapidly at first, as though they might produce the earliest 

 adults. But they linger in the last stage, and the first pupae require from five to 

 nine days to mature. 



" Eggs of aurifer have not been obtained by me ; but there seems little doubt 

 that they are laid like those of canadensis, though probably different in form. 

 The water is drawn from the bogs before the aurifer adults disappear, hence the 

 eggs must be laid in the bog mud, where they rest until they become water cov- 

 ered again in late fall and hatch in the spring following. I have no evidence 

 that there is more than one brood of this species. The pupa is recognizable from 

 that of canadensis by its decidedly larger size and white air-tubes."

Original Desckiption of Aedes cuneatus : 



Female. Proboscis rather long, black-scaled; palpi entirely black-scaled; occiput 

 pale yellowish-scaled, with a brown spot at each side; mesonotum deep brown- 

 scaled, with slight luster, and with two narrow pale yellowish subdorsal stripes; 

 these stripes are thickened along the median portion and become much narrowed 

 on the posterior third, reaching the scutellum outwardly of the antescutellar bare
