 somewhat lighter shaded at joints ; on the last leg I can only make out one dis-

 also."

Original Description of Stec40myia busckii: 



Proboscis and palpi wholly black, no white scales on the first antennal joints, 

 scales of occiput brown, a median stripe of yellow ones, changing to white anteriorly, 

 the sides of occiput bordered with white ones, the lower half largely yellow scaled. 

 Thorax brown-scaled, a median pair of widely-separated yellow scaled lines on the 

 anterior three-fourths of the mesonotum, and between each of these and the adjacent 

 wing is a line of similar scales on the posterior half, an interrupted line of white 

 scales toward the sides of the mesonotum, and several spots on the pleura; scu- 

 tellum brown scaled, and with a median stripe of white ones. Abdomen black 

 scaled, with a tinge of bronze; venter yellow scaled, and with a lateral spot of white 

 scales on the last three segments. Legs black scaled, those on under side of femora 

 pale yellow, a dot of white scales at apex of each femur and tibia, bases of first three 

 joints of the hind tarsi white scaled; tarsal claws in both sexes as in mediovittata . 

 Length about 3 mm.

Description of Female, Mai>e, and Larva of Aedes busckii: 



Female. Proboscis rather long, subcylindrical, very slightly thickened 

 apically, labellae conically tapered; vestiture black; setae short, curved, black, 

 those on labellse more prominently outstanding. Palpi short, about one-sixth 

 as long as the proboscis, slender ; vestiture black ; setae fine, a few of the hasal 

 ones stouter. Antennae filiform, the joints subequal, rugose, coarsely pilose, 

 black; second joint slightly enlarged apically, pale at base; tori subspherical, 

 with a cup-shaped apical excavation, luteous, brown within; hairs of whorls 

 sparse, moderate, black. Clypeus rounded-triangular, convex, blackish -brown, 

 nude. Eyes black. Occiput clothed with flat broad scales, narrow lanceolate 

 ones along median line, black, a narrow silvery-white middle line continued 

 forward between eyes and some scales projecting apically, margins of eyes and 

 lower half of sides silvery-white and including a black patch ; some upright 

 forked black scales well back on the nape; setae along margins of eyes coarse, 

 black, no tuft projecting medianly. 



Prothoracic lobes elliptical, remote dorsally, blackish, with a band of broad, 

 flat silvery-white scales in the middle and with coarse black bristles. Meso- 

 notum rich brown, clothed with narrow hair-like blackish-brown scales, with 

 four longitudinal narrow lines of golden-yellow scales on the disk, the median 

 pair beginning at anterior margin and terminating at antescutellar space, 

 followed by a single golden-yellow line across the space, a slender golden-yellow 

 line on each side of antescutellar space, running forward to beyond middle of 

 disk; a lateral marginal line of silvery-white broad flat scales, involving ante- 

 rior angles and running to roots of wings, somewhat waved and attenuated 

 at its anterior and posterior thirds; bristles over roots of wings coarse, black. 

 Scutellum trilobate, brownish, with small black scales, mid lobe with a patch 

 of broad, flat silvery-white scales, each lobe with a small group of black bristles.
