GENUS ANOPHELES 801 



third white ; antennae with white verticils. Thorax black grounded, 

 ornamented with a median and a pair of lateral lines bordered with 

 white scales ; halteres brownish. Legs deep brown with ferruginous 

 knees and dots on the side of fore and mid femora. Abdomen nearly 

 black, with triangular patches of ferruginous scales on the hind part 

 of the segments. <?. — The palpi slightly shorter than the proboscis 

 clothed with mixed brown and yellow scales, with a yellowish band on 

 apex of second, and often on the two next joints, with large golden 

 tufts to the club. 



This species varies, especially as to palp-banding and fringe spots. 

 It differs from An. argyrotarsis in the basal back band on the last 

 hind tarsal joint, in the white spot near the tip of the wing being separ- 

 ated from the apex by a distinct black area, instead of being purely 

 apical, in having but one instead of two rings on the continuity of the 

 (^ palpi, in the arrangement of the cross-veins in the $ , and in being 

 altogether a darker species. 



The larvae are found in streams and pools feeding on fibrous green 

 algae, and vary from grey-brown to greenish, with white patches (T. M.). 

 The adults are rarely found in European houses (Freeland). LevgtJi. — 

 Of 3- 3-5 to 4-5 mm. ; of ? 4 to 4-5 mm. 



Habitat. — Jamaica (Dec. to February), Brit. Guiana, Kio Janeiro, 

 Antigua (March).

Wing with the costa black, but creamy-yellow just at the 

 apex, with two large outer, two small middle spots, and two 

 large basal dots, six in all, of the same tint ; on II, beneath the 

 large black middle area, are two small white interruptions ; the 

 rest of the wing is generally pale, but there are prominent black 

 lengths on all the long veins, and the fringe is patched with 

 yellow at each of the long junctions. Last hind tarsal joint all 

 white, and its other joints banded on the articulations, as are 

 those also of the upper tarsals of the fore and middle legs. 

 Thorax dark grej', with brown lines, and a dark patch on 

 either side, clothed with scattered falciform white scales, 

 some long ones of which project from the anterior border. 

 Abdomen black, with golden hairs, very dense towards the 

 apex. 



Head black, with black fork- scales except on a triangular patch in 

 front, where they are white, especially large in the ^ ; basal joints of the 

 antennae with some white scales ; palpi black, with the last joint and 

 rings on the articulations white in the ? , less marked in the ^ , in
