ANOPHELES EISENI 1005 



Abdomen subcylindrical, depressed, truncate at tip, brownish-black, without 

 scales, clothed dorsally with scattered fine brown hairs; venter pale greenish, 

 the apices of the segments blackish, more coarsely hairy. 



Wings (plate 41, fig. 16) moderate, hyaline; petiole of second marginal cell 

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

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

 scales of veins rather broadly lanceolate, blackish brown, intermixed with deeper 

 black ones in indistiact patches as follows : at base of second vein and base of 

 its fork, on third and fourth veins at the cross-veins and base of fork of fourth 

 vein, fifth vein from base to apex of lower branch, a spot on upper branch ; a dull 

 brownish-white spot at costal margin just before wiag-tip and involving first 

 vein, a second one on the fringe at wing-apex; a small yellowish spot on first 

 vein before middle of wing. Halteres whitish, with black knobs. 



Legs long and slender; vestiture black, apical fourth of posterior tibiae 

 densely clothed with large, slightly raised, lanceolate white scales ; femora pale 

 beneath at base. Claw formula, 0.0-0.0-0.0. 



Length : Body about 4.5 mm. ; wing 4 mm. 



Male. — Proboscis rather long and slender, straight. Palpi nearly as long as 

 the proboscis, the tip of long joint and last two joints swollen and furnished 

 with long hairs; vestiture black, last joint entirely white-scaled, penultimate 

 dorsally white at base. Antennae plumose; last two joints long and slender, 

 rugose, pilose, black, the others rather short, subequal, slender, whitish on 

 apical half, dark basally; hairs of whorls long, dense, blackish. Coloration as 

 in the female. Abdomen elongate, subcylindrical, slightly narrowed towards 

 middle, depressed and somewhat broadened towards apex; lateral ciliation 

 coarse but sparse. Wings much narrower than in the female, the stems of the 

 fork-cells longer, the vestiture more sparse. Claw formula, 3-0.0-0.0. 



Length : Body about 4 mm. ; wing 3 mm. 



Genitalia (plate 40, fig. 367) : Side-pieces rather slender, conically tapering, 

 rounded at tip, over twice as long as wide; clasp-filament long, rather slender, 

 slightly attenuated medianly, apically with a minute stout inserted claw ; at base 

 of side-piece are two pairs of stout setse arising from elevated bases. Basal 

 appendages broad, tapering to a point, smooth. Unci forming a slender column, 

 from the tip of which arise two filaments with serrate outer edges. 



Larva, Stage IV. — Head rounded, elongate, longer than wide, bulging at 

 sides, front conically produced ; four dorsal head-hairs, single but numerously 

 branched, in a line between the antennae, a smaller hair at base of antenna; 

 two long approximate spines on front margin. Antennae subcylindrical, slightly 

 tapered, sparsely spined; a hair tuft very near base; two long terminal processes, 

 a slender hair-tuft exceeding them and a digit at tip. Eyes large, pointed. 

 Mental plate small, with a median tooth and four on each side, the second rather 

 prominent, the third and fourth small and distant. Mandible quadrangular, 

 with a row of long feathered hairs near base and a pair of short feathered fila- 

 ments on the other side ; two long smooth filaments and two serrate ones before 

 tip ; an outer row of cilia ; a row of short feathered filaments along outer margin; 

 dentition large, of seven teeth, the third large and prominent, the fourth a 

 serration on its lower declivitjr; a long serrate filament within, a rounded 

 process below composed of confluent spines ; basal angle small, with a hair-tuft ; 

 a row of long hairs at base. Maxilla rectangular, slightly excavated at inner 

 third, fringed with hairs, with two stout spines at inner angle; two small fila- 

 ments at base of excavation; palpus conical, not exceeding the maxilla, a den- 

 dritic tuft without; a group of digits and fiattened appendages at tip. Thorax 

 subquadrate, about as long as wide; hairs short, consisting of branched hairs, 

 single hairs and tufts; mesothorax sparsely haired. Abdomen stout, anterior 

 segments shorter; long feathered lateral hairs on first three segments, double 

 on first and second, single on third ; posterior hairs small, smooth ; a dorsal series 

 of six pairs of fan-shaped tufts on second to seventh segments (plate 130, fig.
