joints each slightly shorter than the eleventh ; proboscis scarcely longer than height of 

 head, palpi inserted slightly beyond its middle, nearly twice as long as the proboscis, 

 eyes widely separated, deeply emarginate opposite insertion of antennce, no ocelli, 

 first tarsal joint much longer than the second, venation as in Ctilex. Type Coretlira 

 brakeleyi Coquillett. 



The radical structural differences existing between the larva of the 

 present form and that of a typical species of Corethra have already 

 been commented upon by Prof. J. B. Smith, and are clearly shown 

 in the excellent figures published by Dr. Dyar in the present number 

 of the Journal. This and the further fact that the structure and 

 pilosity of the antennae of the adults are markedly different, clearly 

 indicate the desirability of separating these two forms into distinct 

 genera. 



Anopheles eiseni, sp. nov. 



Near maculipeuiiis, l:>ut with a patch of whitish scales on the first vein before its 

 middle and another at its apex, also the apical fourth of the hind tibise is yellowish-

 pleura, yellow, femora yellowish-brown, apical fourth of hind tibiK yellowish-white ; 

 antennEe of male whitish, the first joint, last two and fascia on each of the others,

 claws of female simple ; wings hyaline, the veins and scales brown, a dense patch of 

 black ones at base of second vein, a larger one on the crossveins and a small one at 

 bases of first submarginal and of second posterior cell, a small patch of yellowish- white 

 scales on first vein before its middle and another at its apex, the latter spot encroach- 

 ing upon the costal vein. Length, 3.5 mm. 



Habitat. — Aguna, Guatemala (2,000 feet altitude). 



One female and two males received by Dr. L. O. Howard from 

 Professor Gustav Eisen, of San Francisco, Cal., who has brought to 

 light several interesting forms in this family, and to whom this species 

 is respectfully dedicated. Type No. 6699, U. S. National Museum. 



Culex dyari, sp. nov.

 claws in the female, etc. Dark brown, thorax more reddish-brown, stems of halteres, 

 coxae and greater portion of posterior side of femora, yellow ; antenna; of male largely 

 white on the intermediate short joints, the plumosity brown, with a yellow base ; scales 

 of palpi brown, the female having those at the apices white, the male with four rings 

 of whitish ones, last joint of male palpi dilated, scales of occiput narrow, yellowish, a
