ANOPHELES PUNCTIPENNIS 1011 



Oeiginai, Descbiption of Anopheles perplexens: 



(Female.) — Head dark, with dark brown and white fork scales, the latter nearer 

 the vertex, and a heavy tuft of slender, long curved white scales projecting cephalad 

 between the eyes; antennae dark brown, verticels and pubescence dark, basal joint 

 brown; palpi dark, covered with dark brown scales, a small tuft of white hairs at 

 the very tip; proboscis dark with dark brown scales, tip testaceous; clypeus dark, 

 eyes brown. 



Thorax: prothoracic lobes testaceous, with dark hairs; mesonotum with broad, 

 light median stripe, covered with white " frost," and white hairs arranged so as to 

 suggest a " part," a dark median line extending half way to the scutellum, and two 

 dark lateral bordering lines; more or less of a tuft of these hairs at the nape; 

 laterad the dorsum is dark brown, with dark brown hairs; pleura brown; scutellum 

 testaceous, " frosty," with brown bristles ; metanotum dark brown. 



Abdomen dark brown, with light hairs (no scales). 



Legs: Coxae and trochanters light, mostly light scaled; femora ventrally light 

 scaled, and extreme tips of femora and tibiae ochraceous, remainder of legs dark 

 brown; ungues simple. 



Wings clear, and rather heavily clothed with dark brown scales, except a few 

 small ochraceous spots — one on the costa, just interior to a line drawn through the 

 junction of the branches of the fork cells, a second tiny spot at the junction of the 

 first long vein with the costa, extending a tiny bit on the long vein, and two very 

 small faint light spots on the forks of the fourth long vein, also a tiny fringe spot 

 at the distal end of the third long vein; hal teres with light stems and fuscous knobs. 



Length, 2.5-3 mm. Habitat, Camp Roosevelt, Mt. Gretna, Pa. Taken August 25, 

 1906. 



This interesting species was sent by Capt. E. B. Whittemore, Asst. Surg. XJ. S. 

 Army, and, as will be seen from the description, bears a closer resemblance to 

 tropical Anophellna than to those so far reported from the U. S., but as the group 

 it most closely resembles has abdominal scales and rather broader wing-scales it 

 cannot be referred to it. 



Description of Female, Male, Larva, Ptjpa, and Egg of Anopheles punctipennis : 



Female. — Proboscis moderate, rather slender, slightly thickened basally, 

 smoothly scaled; labellas long, lanceolate, luteous, with fme outstanding black 

 setas ; vestiture black with a slight bluish reflection. Palpi about as long as the 

 proboscis, slender, uniform, somewhat roughened by raised elliptical scales 

 towards base, brownish-black, some short setse at tip. Antennse filiform ; second 

 joint long and thickened, the others shorter, subequal, rugose, blackish, densely 

 pilose ; hairs of whorls sparse, short, black ; tori small, subspherical, with a cup- 

 shaped apical excavation, blackish without, rim luteous. Clypeus broad, 

 rounded triangular, blackish, nude. Eyes well separated on the vertex, black. 

 Occiput with a median groove, dark brown, densely clothed with erect, elongate 

 triangular scales, black behind and at the sides, creamy-white on the vertex, a 

 group of long white hair-like scales between the eyes and projecting forward ; a 

 row of black setae along margins of eyes. 



Prothoracic lobes lateral, prominent. Mesonotum narrow, elongate, blackish- 

 brown on the sides, a broad, median, longitudinal, light gray, strongly pruinose 

 stripe, marked with three impressed lines on anterior two-thirds, a short median 

 black line basally on antescutellar space; vestiture of scattered pale yellowish 

 hair-like scales, denser at anterior margin. Scutellum collar-like, grayish- 

 brown, pruinose, an ill-defined median black stripe continuous with that on 

 mesonotum; sparsely clothed with pale hairs and with blackish marginal 

 bristles. Postnotum elliptical, prominent, dark brown, pruinose, nude. Pleurae 

 variegated in blackish, gray pruinose, and whitish, with a few fine hairs ; coxes 

 luteous. 



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

 bases of segments ; dorsal vestiture of rather long, fine pale hairs arising from 

 very small black punctures. 



Wings (plate 41, fig. 7) moderate, hyaline; petiole of second marginal cell 

 much shorter than its cell, that of second posterior cell about equal to its cell ; 

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

 ing scales of veins rather narrowly lanceolate, dense, black and yellowish-white, 

 the black predominating, the white disposed as follows : a large patch of white
