994 MOSQUITOES OF NORTH AMERICA 



fork-cell has its branches thickly clothed with pale small brown and grey scales In 

 patches and with a few black Cycloleppteron scales at its base, so also has the 

 greater part of the third vein and the branches of the second fork-cell, the stems of 

 the fork-cells and basal portions of the other veins with scattered black inflated 

 scales; the sixth has grey scales, especially along its basal half, and three small spots 

 of inflated black ones; fringe pale, apparently unspotted; halteres large, fuscous. 



Length. 5 mm. 



Habitat. Brazil (Dr. Lutz). 



Observations. Described from a perfect c^. It is the most beautiful Anopheles 

 I have seen. Together with this (^, Dr. Lutz sent me a preparation of the $ wing. 

 This shows typical Cycloleppteron scales. Later he sent me several 5's, which he 

 came to the conclusion were the $'s of the male here described, and mentions that 

 the $ wing sent was that of a male C. mediopunctatus. These 5's presented no 

 Cycloleppteron characters, and moreover are black and silvery grey, not the brilliant 

 golden hue seen in the male Cycloleppteron. The 2 ot C. Orabhamii has true Cyclo- 

 leppteron scales, but the $'s sent by Lutz have none whatever; in fact, I feel certain 

 that they are not the $'s of this species, but quite distinct, although they have 

 assumed the general appearance of the Cycloleppteron. Moreover, the wing sent me 

 as that of a 2 certainly differs from the (^'s I have examined, and I venture to think 

 Dr. Lutz was correct in his flrst surmise, the difference being noticeable in the 

 relative positions of the fork-cells, and, to some extent, the cross-veins, which, 

 however, may be variable. 



Description of Female of Anopheles mediopunctatus (Labva Unknown) : 



Female. Proboscis moderate, straight, enlarged toward base; labellae long, 

 lanceolate, with fine outstanding setce; vestitnre black, roughened basally. 

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

 black intermixed with a few white ones. Antennae filiform, the joints subequal, 

 rather short, pale, blackish at bases, densely pilose; hairs of whorls sparse, 

 black, rather short; tori small, subspherical, with an apical cup-shaped exca- 

 vation, brown, with a luteous spot and a patch of yellowish scales. Clypeus 

 large and broad, rounded triangular, brown, nude. Eyes narrowly separated on 

 the vertex, black. Occiput with a median groove, brown, densely clothed with 

 erect truncate black scales, a few white ones in the center of the vertex, a tuft 

 of long white hairs projecting forward between eyes; a row of long black setae 

 along margins of eyes. 



Prothoracic lobes small, lateral. Mesonotum narrow, elongate, light pinkish- 

 gray, pruinose, irregularly mottled with deep brown dots, heaviest along median 

 line, two narrow impressed concolorous longitudinal stripes on anterior half of 

 disk, a round black spot medianly on each side well towards lateral margins, a 

 large black spot on antescutellar space ; vestiture of scattered pale yellow hair- 

 like scales and fine pale hairs, some semi-erect whitish ovate scales on anterior 

 margin and along sides of disk. Scutellum collar-like, grayish, with a large 

 black spot in the middle, contiguous with that on antescutelllar space, clothed 

 with pale fine hairs and coarse brown marginal bristles. Postnotum elliptical, 

 prominent, pale brown, pruinose, nude. Pleurae and coxse pale grayish-prui- 

 nose, with large dark brown spots; hairs pale; coxae with patches of erect ovate 

 white scales. 



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

 pruinose, evenly clothed with numerous fine pale hairs, intermixed with a few 

 broadly triangular white scales posteriorly; venter with many similar white 

 scales and the apices of the segments with bands of broad, erect black scales 

 forming outstanding tufts on the posterior angles of the segments. Cerci 

 clothed with similar scales. 



Wings (plate 41, fig. 17) moderate, hyaline, pigmented with brown on three 

 costal spots and a small one at cross-veins ; petiole of second marginal cell nearly 

 as long as its cell, that of second posterior cell about as long as its cell ; basal 

 cross-vein distant about its own length from anterior cross-vein; outstanding 

 scales of veins broadly elliptical, partly almost circular, black and white inter- 

 mixed, with black ones in spots as follows ; three large spots on the costa involv- 

 ing subcostal, first and second veins, a small apical one at end of second marginal 

 eell, small spots at base of third vein, base of fork of fourth and at basal cross-
