AEDES CURRIEI Coquillett. 



Adults which appear referable to this species were taken at Thrall, 

 California, and Klamath Falls, Oregon. They are inseparable from 

 quaylei hy the dorsal marking of the thorax, as in one specimen the 

 stripe is as broad as in the usual (juaylei, in another narrow. There 

 are, however, less black scales on the wings in these carriei^ and 1 am 

 reluctant to believe that they can be the same species as the salt marsh 

 form. The larvae, unfortunately, were not found, but we have them 

 from Grand Junction, Colorado, collected hy Mr. E. P. Ta3'lor, and 

 from Ithaca, New York, collected by Mr. O. A. Johannsen. These 

 larvae ditJ'er from quaylei in the structure of the comb, the scales of 

 which end in a single stout spine. It is probable that the Californian 

 ones will be found to have the same structure and thus be distinguish- 

 able from both quaylei and squa7niger. The larvse appear to come 

 early, perhaps in the tirst temporary pools, and have but a single 

 annual brood. The species was apparently absent from southern 

 California and the coast region. 



STEGOMYIA CALOPUS Meigen. 



Mr. Knab tells me that he has seen a reference to the '"yellow fever 

 mosquito " as occurring on the coast of California. It is certainly not 

 a native of the State. I did not meet with it even in the wharf vats at 

 San Diego, which would seem the most likely place. 



MANSONIA SIGNIFER Coquillett. 



This has been recorded from California bj- Miss Ludlow. I have 

 not seen any specimens. The larva? are well known inhabitants of 

 hollow trees, but our other records do not carry the species west of 

 Missouri. 



URANOT^NIA ANHYDOR, new species. 



A single larva was collected in a swamp full of reeds at Sweetwater 

 Junction, near San Diego, Avhich died before reaching home. Mr. 

 Caudell and I made a special trip to the swamp later to get more larvse, 

 but it had gone dry, leaving little puddles of dying fish and a great 

 quantity of Anopheles larvae, all of which no doubt died within twenty- 

 four hours. 



Larva. — Head rounded, scarcely longer than wide, neck circular, 

 the occiput oblique, roundedly angled at the side, then nearly straight, 

 the front margin broadly, square!}^ truncate; labrum deeply excavate 

 each side of the middle, forming a triangular horn-like prominence 

 in the middle and one on each side, midway between the central one 

 and the antenna\ Eyes large, semicircular, transverse: two approx- 

 imate multi})l(' hair tufts above and within the eye, another on
