ANOPHELES MALEFACTOR 1001 



Type.— No. 10877, U. S. National Museum. 



There is some variation in the banding of the hind tarsi. In two specimens the 

 penultimate and apical white rings of the second joint are united; in one the apical 

 white ring of the first joint is divided by a black bar, in another the penultimate 

 ring is so divided, while in a third, the apical, penultimate, antepenultimate and 

 another white ring are so divided, this specimen having eleven white rings on this 

 joint instead of seven as in the type. 



Description op Female, Male, and Labva of Anopheles malefactor : 



Female. — Proboscis moderate, straight, rmiform; labellae long, lanceolate, 

 with fine outstanding setae; vestiture black, roughened basally. Palpi nearly 

 as long as the proboscis, stout, roughened by long erect spatulate scales, black, 

 a few yellowish ones intermixed, a pale ring at base of last joint and at middle 

 of long joint. Antennae filiform, the joints subequal, rather short, blackish, 

 densely pilose; hairs of whorls sparse, pale, short; tori small, subspherical, with 

 a cup-shaped apical excavation, dark brown, with a patch of pale scales on outer 

 side. Clypeus broad, rounded triangular, dull brown, nude. Byes well sepa- 

 rated on the vertex, black. Occiput with a median groove, piceous, densely 

 clothed with erect triangular spatulate black scales with paler tips, some yel- 

 lowish-white ones on the vertex; a row of recumbent white scales along eye 

 margins extending forward to their anterior angles ; a group of long pale hairs 

 between the eyes projecting forward; hairs along margins of eyes long, black. 



Prothoracic lobes small, lateral, clothed with erect spatulate black scales. 

 Mesonotum narrow, elongate, brownish-gray, pruinose, irregularly mottled 

 with small deep brown dots; a pair of indistinct, narrow, longitudinal bare 

 lines on anterior half of disk ; a pair of broader bare lines outward on posterior 

 half, a large black spot at their anterior ends near lateral angles, a large black 

 spot basally on antescutellar space ; vestiture of fine pale yellowish hairs, mostly 

 arising from black spots, some long, narrow pale scales intergrading with the 

 hairs near anterior margin, a few erect, spatulate black scales at anterior angles ; 

 bristles over roots of wings short, pale yellow. Scutellum collar-like, gray 

 pruinose, with a black spot in the middle continuous with that on mesonotum, 

 clothed with pale hairs and dark marginal bristles. Postnotum elliptical, 

 prominent, dark brown, nude. Pleurae and coxae pale gray pruinose with 

 blackish patches, fine hairs, and small patches of white scales. 



Abdomen subcylindrical, depressed, truncate at tip, brownish-black, evenly 

 clothed with fine pale hairs and some scattered broad pale scales on last three 

 segments, a series of conspicuous tufts of black spatulate outstanding scales at 

 posterior angles of segments with some white ones near them; venter with 

 scattered broad white scales, hind margins of segments with coarse, erect black 

 scales. 



Wings (plate 41, fig. 3) moderate, hyaline, with three brown pigment spots 

 along costa and two smaller ones on the cross-veins ; petiole of second marginal 

 cell nearly as long as its cell, that of second posterior cell somewhat longer than 

 its cell ; basal cross-vein distant about its own length from anterior cross-vein ; 

 outstandiag scales of veins broadly ovate, small, white and pale yellow with 

 black ones ia spots as follows : three large spots on the costa, limited at both ends 

 by white scales, the membrane beneath them infuscated, the basal one smaller, 

 involving subcostal and first veins, the others very large, involving the second 

 vein, the outer one both branches of its fork ; numerous black scales on the costa, 

 subcostal and first veins between the large spots and beyond, apically and sub- 

 apically, small irregular spots ; third vein with two small spots at and near base 

 and two others at and near apex, a few black scales scattered along its whole 

 length ; fourth vein mostly black-scaled to the fork, a larger spot on the base of 

 the fork, three smaller on upper branch and three on lower ; fifth vein with black 

 scales intermixed, five spots on upper fork, two on lower ; sixth vein with seven 

 small black spots. Halteres pale at base, scaled with white on upper side, the 

 knobs black with broadly white-scaled margins.
