886 MOSQUITOES OF NORTH AMERICA 



Orthopodomyia fascipes was described in the wrong genus, the author having 

 been deceived by the shape of the wing-scales. This error led to much confusion, 

 to which we have already referred under our discussion of the genus. Newstead 

 and Thomas redescribed the species, also as a Mansonia, evidently being un- 

 acquainted with Coquilletfs description published five. years earlier. Later 

 Newstead and Carter needlessly established the genus Thomasina for this 

 species. 



Our specimens show great variation in the tarsal ornamentation. Some speci- 

 mens have the last three tarsal joiats of all the legs wholly yellowish white scaled 

 and the preceding joints more extensively pale scaled. Others show more or 

 less extensive black rings or spottings on the third joint of front and middle 

 tarsi ; where these joints are heavily marked with black, the fourth joint of the 

 hind tarsi usually bears a black median ring ; the extreme is reached in speci- 

 mens which have in addition a narrow black subapical ring on the third joint 

 of the hind tarsi. The irregular spottings of the legs are also subject to con- 

 siderable variation. On the front and middle tarsi the markings on the distal 

 joints are usually somewhat obscured by a submetallic luster. There seems to be 

 little tendency to the formation of local races, as our small series from different 

 localities show much the same range of variation.

OmaiNAi. Descmption of Bancroftia peesephassa: 



Female. — Proboscis black-scaled, a white ring at the middle. Thorax clothed with 

 narrow golden scales, with a subdorsal narrow bare line on either side, the sides 

 of the disk dark except for a patch of golden scales over the root of the wing. Abdo-

 basal segmental spots, venter black, with narrow white basal bands. Wings hyaline, 

 the scales dusky black, the outstanding ones broad, obliquely subtruncate at the tip. 

 Legs black-scaled, the femora with the apices yellowish white and a ring of this 

 color at the apical third; tibise similarly marked; tarsi of the hind legs ringed with 

 white at both ends of the joints, the last joint black at the tip ; front and mid tarsi 

 with the markings similar, but obsolete on the last three joints. Length, 3.5 mm.

Descbiption of Female of Orthopodomyia persephassa (Male and Larva Un- 

 known) : 



Female. — Proboscis moderately long and slender, uniform; vestiture black, 

 a broad white ring beyond middle ; setse minute, curved, black, those on labellae 

 more prominently outstanding and pale yellowish. Palpi short, about one-fifth 

 the length of the proboscis, black-scaled, tips white scaled, with rather numerous 

 black bristles and shorter cilia. Clypeus rounded triangular, prominent, 

 black, nude. Antennae filiform, moderate, the joints subequal, rugose, pilose, 

 black; hairs of whorls sparse, moderate, black; tori small, subspherical, with a 

 cup-shaped apical excavation, brownish luteous, a large patch of yellowish 

 scales on inner side. Eyes black. Occiput dark brown, clothed with narrow, 

 curved golden-yellow scales, margin of eyes and lower part of sides with flat 

 whitish scales ; many erect forked black scales on the nape, a broad median area 

 on vertex with very broad, erect, golden yellow ones ; bristles along margins of 

 eyes coarse and long, brown, a tuft of long yellow ones prejocting forward 

 between the eyes.
