Dec, 1907.] DyAR & KnAB : MOSQUITOES FROM CaNAL ZoNE. 201 



One specimen, Taboga Island, Panama (A. H. Jennings, col- 

 lector), bred from larvge from pool in a small stream. 



Type. — No. 10918, U. S. National Museum. 



In the single specimen the thorax is somewhat denuded and it is 

 possible that there may be a blue spot before the antescutellar space. 



Aedes lithoecetor, new species. 



9 • — • Proboscis moderately long, rather slender, black scaled ; palpi short, 

 black scaled ; occiput clothed with pale-yellowish scales, narrow curved ones on the 

 vertex, flat ones on the sides, a small black patch on the lower part of the side ; 

 mesonotum with the anterior two-thirds clothed with shining light-yellow scales, a 

 dark patch in front of the sides, posterior portion varied with blackish and pale-yel- 

 low scales, a patch at the side separated by a yellow stripe running from the middle 

 to the base of the wing ; scutellum yellow scaled ; pleura dark with patches of white 

 scales ; mesonotum deep brown, nude ; abdomen black-scaled above with median 

 basal elongate creamy spots on all the segments, which however do not unite to form 

 a stripe, segments with lateral triangular basal white patches, beneath the abdomen 

 is mostly creamy white with black apical lateral triangular marks; legs black, knees 

 yellow scaled, tarsi with narrow yellowish-white basal rings, the ring at the base of 

 the second tarsal of the hind legs slightly involves the apex of the first joint ; fork- 

 cells rather short, scales of the veins all dark ; claws of front and mid legs toothed, 

 of hind legs simple. Length, 5 mm. 



$ . — Palpi slightly shorter than the proboscis, hairy on the apical portion, the 

 two apical segments light ringed at their bases ; abdomen with distinct basal white 

 bands on the second to fourth segments, on the succeeding segments broken into 

 three spots, the median spot becoming elongate on the sixth and seventh segments, 

 lateral cilia abundant, pale. Length, 4 mm. 



Five specimens, Chagres River, Panama (August Busck, col- 

 lector), bred from larvae in pot-holes along the river. 



Type. — No. 10868, U. S. National Museum. 



Apparently nearly allied to Danielsia tripunctata Theobald and to 

 Danielsia medioviaculata Theobald, the abdominal marking differing 

 from the former and the thoracic marking differing from the latter. 

 We would place Danielsia Theobald as a synonym of Aedes in our 

 classification. 



Culez jubilator, new species. 



9 . — Proboscis rather long and slender, not swollen towards the apex, clothed 

 with black scales, not ringed ; palpi short, black scaled ; occiput clothed with narrow 

 yellowish scales, margin of the eyes narrowly white, the upright forked scales brown 

 with yellow luster ; mesonotum light brown with golden luster ; pleura pale gray ; 

 abdomen subcylindrical, truncate at apex, black scaled above with faint bronzy luster, 

 segments 2 to 7 with a median basal triangular spot of white scales, the spots on the 

 posterior segments smaller, eighth segment with a white basal band, which is laterally 

 enlarged, a row of white lateral spots, ventral area white scaled ; legs black with
