ANOPHELES GKABHAMII 1007 



some lights, with purplish tinges in others. When viewed with a hand lens the 

 thorax appears bright brown and grey, frosted with grey hairs, the median dark line 

 showing plainly, and also the four lateral spots. 



The abdomen is absent, and the legs too damaged to make anything of, but the 

 remaining wing is perfect, and presents the following peculiarities: the costa is 

 dark, with a small pale patch about one-third of the length of the wing from the tip. 

 The apex is fringed with yellow scales, broken by three small blackish patches, the 

 upper part of the yellow fringe appearing as a yellow, apical, costal spot. The veins 

 are sparsely bordered with pale spindle-shaped scales, and scattered over the veins, 

 at wide intervals, are large, deep black scales totally unlike those of any other 

 Anopheles. These scales are collected into a dense jet-black spot where the first 

 long vein joins the auxiliary, the black spot of scales involving the second long vein 

 as well. They are also collected rather thickly at the root of the fork-cells, especially 

 of the first sub-marginal cell and elsewhere. The first sub-marginal cell is about 

 the same length as its stem; its base nearer the base of the wing than that of the 

 second posterior cell. The latter is very short and broad, only a little more than half 

 the length of its stem. Posterior cross-vein about its own length distant from the 

 mid cross-vein. The third long vein is carried only a minute distance past the pos-

Time of capture. November. 



Observations. Described from a single broken specimen. Sufficient remains, 

 however, to show a very marked and peculiar species, which can at once be told 

 from any other Anopheles by the large dark scales on the wings. This species 

 probably will form a new genus when sufficient material comes to hand. The remains 

 have been mounted on slide No. 27.

Description of Female, Male, and Larva of Anopheles grabhamii: 



Female. Proboscis moderate, rather slender and smoothly scaled, slightly 

 thickened at base; labellas long, rather large, lanceolate, with fine outstanding 

 setae; vestiture brownish-black, slightly roughened at base. Palpi nearly as 

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

 throughout, a few short setae at tip. Antennae filiform; second joint elongate 

 and thickened, the others short, blackish, densely pilose ; hairs of whorls sparse, 

 very short, black ; tori rather small, subspherical, with a cup-shaped apical ex- 

 cavation, deep brown, pruinose. Clypeus large and broad, rounded triangular, 

 blackish, pruinose, nude. Eyes well separated on the vertex, black. Occiput 

 with a median groove, piceous, densely clothed with erect triangular scales, 

 black on the sides, white on the vertex, a group of long hair-like white scales 

 between eyes projecting forward ; a roAv of black setae along margins of the eyes. 



Prothoracic lobes small, lateral. Mesonotum narrow, elongate, dull brown- 

 ish, gray pruinose, a black spot on each side medianly near lateral angles and a 

 small one basally on the antescutellar space ; vestiture of scattered, short, pale 

 yellowish hairs, some erect, narrow, elongate white scales near anterior margin. 

 Scutellum collar like, brownish, gray pruinose, with a large black central spot, 

 clothed with sparse pale hairs and black marginal bristles. Postnotum ellip- 

 tical, prominent, light brown with a blackish central stripe, nude. Pleurae and 

 coxae brownish, gray pruinose, mottled with black, with rows of fine hairs and 

 a few white scales on the coxae. 



Abdomen subcylindrical, depressed, truncate at tip, blackish, somewhat 

 rugose, rather evenly clothed with scattered, short, fine shining hairs, some 

 small yellowish white narrow outstanding scales at apical angles of last 

 segment. 



Wings (plate 41, fig. 6) rather narrow, hyaline; petiole of second marginal 

 cell shorter than its cell, that of second posterior cell longer than its cell ; basal 

 cross-vein distant less than its own length from anterior cross-vein; scales of 

 veins of two kinds, large, broadly elliptical ones, tending to form spots on the 

 veins, the others much smaller and lanceolate ; large scales mostly black ; costa 

 black-scaled, a small yellowish-white patch on the outer third and involving first 

 vein, a longer ochreous-yellow spot at tip of wing on fringe and tip of first vem, 

 extending to second marginal cell and interrupted by a black spot at u]iper
