creamy, light brown at the curve. Abdomen with golden hairs, narrow curved 

 golden scales on genital lobes. Legs unhanded, light orange. Ungues equal and 

 simple. Wings unspotted ; scales narrow, creamy or light yellow. Base of 1st 

 submarginal cell nearer the wing base than that of 2nd posterior ; the cell is longer 

 than its stem, 2nd posterior cell shorter than its stem. Supernumerary and 

 anterior cross- veins meeting, the posterior one more than twice its length from the 

 latter ; 3rd longitudinal vein not ending at the meeting of the supernumerary and 

 anterior cross- veins. Length, 4-5 mm. 



cJ. Like $. Club-shaped end of palpi yellow, owing to the presence of long 

 yellow hairs mixed with the creamy scales ; a dark narrow band caused by partial 

 desquamation. Narrow-curved creamy scales on the two apical abdominal seg- 

 ments. On the wing, anterior cross-vein situated basally from the supernumerary. 

 Larva unknown. 



Java : Soerabaia. Sumatra : Mandaihng. 



Rare. Described from 3 59 ^^^ ^ (SS taken at Soerabaia, June 1917. Easily 

 distinguished from other unspotted Anophelines by the long palps (M. brevipalpis) 

 and the broadly expanding upright forked scales on the head (S. aitkenii). The 

 species may perhaps be an albinoid variety of M. vaga (indefinita), as this species 

 sometimes shows a marked decrease of the black portions on the wings and palpi. 



2. Nyssorhynchus annulipes var. moluccensis, Swell. (1920). 



A rather large brown mosquito, with spotted legs, 4-5 light bands on palpi, 

 the apex of the 2nd joint being black ; proboscis dark, except labella ; narrow 

 curved scales on the whole dorsal surface of the mesonotum ; wings much spotted, 

 resembling those of N. punctulata var. tesselata. 



§. Head scaled as in other Nyssorhynchi. Antennae light brown, basal segment 

 with small white scales, verticils and tomentum golden. Proboscis dark brown.

labella lighter. Palpi (fig. 1) : 1st joint black with creamy apex and sometimes a 

 dorsal yellow spot in the middle ; 2nd joint black, with a broad white band on 

 apical half and a narrow yellow one at the apex, sometimes a yellow dorsal spot 

 in the middle of the black basal portion, the sub-apical white band sometimes narrow 

 or even absent ; penultimate and terminal joints with a narrow black basal band, 

 then a narrow yellow band, the remaining portion creamy. Thorax : prothoracic 

 lobes blackish brown, with black chaetae and a tuft of black scales in front. Meso- 

 notum with a dark spot to the right and left at one-third from the anterior border 

 and one in front of scutellum, covered all over with narrow curved white scales,
