Anopheles apicimacula is one of a group of closely similar species, which agree 

 in the wing-pattern, the presence of abdominal lateral scale-tufts, and in having 

 mottled legs. It is distinguishable from mediopunctatus and malefactor by the 

 more narrowly ovate wing-scales, agreeing in this respect with strigimacula and 

 maculipes. The last named differs by having the rings on the hind tarsi at the 

 apices of the joints, while the others have them at both ends of the joints. The 

 most obvious difference between apicimacula and strigimacula is that in the 

 former the rings of the hind tarsi are white and rather scattered, while in the 

 latter they are yellow and very numerous. There is considerable variation in the 

 extent of the light scaling, both on the wings and tarsi. The third vein usually 

 bears only two black spots, one near base, the other near apex ; but some of our 

 specimens show additional spots. The spots on the sixth vein are very variable 

 in number and extent. The last hind tarsal may be either wholly white, or with 

 a black ring. 



We have simk Anopheles punctimacula as a synonym of apicimacula, further 

 study having convinced us that the differences on which the species was based, 

 the less concrete black apical wing-spot and the wholly white last joint of the 

 hind tarsi, are not specific.

Description or Female, Male, and Labva or Anopheles STEiaiMACtTLA: 



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

 with fine outstanding setae; vestiture black, roughened toward base. Palpi as 

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

 a few whitish scales at apex, at bases of last two joints and at middle of long 

 joint. Antennae filiform, the joints subequal, pale, with black basal rings, 

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

 an apical cup-shaped excavation, brown, with a luteous rim and a patch of ovate 

 white scales on outer side. Clypeus broad, rounded triangular, brown, pruinose, 

 nude. Eyes well separated on the vertex, black. Occiput with a median groove, 

 blackish, clothed with erect, truncate black scales, a group of white ones in the 

 center of the vertex, a row of recumbent white scales along eye-margins to their 

 anterior angles, a group of long pale hairs projecting forward from interocular 

 area ; hairs along eye margins long, black. 



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

 Mesonotum narrow, elongate, pale grayish-pruinose, irregularly mottled with 

 deep brown dots ; a pair of indistinct, narrow, longitudinal bare lines on anterior 

 half of disk ; a pair of broader bare stripes well outward on posterior half, a large 

 black spot at their anterior ends near lateral angles, a larger black spot basally 

 on antescutellar space; vestiture of fine pale yellow hairs arising from small 

 black punctures, 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, grayish 

 pruinose, with a large black spot in the middle continuous with that on meso- 

 notum, clothed with pale hairs and brown marginal bristles. Postnotum ellip-
