4 nopheles immaculatus . 



brown, with ochraceous reflections, the tarsi dark in some lights, 

 with pale apical bands ; wings with ochraceous veins, unspotted. 



Head dark brown, with grey upright-forked scales in front, 

 ochraceous and darker ones behind, while narrow-curved scales in 

 front form a more or less projecting mass, beneath which arises 

 a tuft of long white hair-like scales ; antennse brown, the basal 

 joint bright testaceous, the next few joints with pale scales ; palpi 

 short for an Anopheles, rather thick, covered with dense brown, 

 grey and ochraceous scales, the brown scales basal, the others form- 

 ing most of the apical covering ; proboscis about the same length 

 as the palpi, ochraceous brown with a paler tip. 



Thorax ashy-brown with slaty reflections, with darker longi- 

 tudinal lines, one being median, the surface with pale golden, hair- 

 like curved scales, a tuft of pale scales projecting over the head in 

 front ; scutellum with narrow-curved, hair-like, pale golden scales, 

 and brown border bristles ; metanotum deep brown. 



Abdomen deep brown to black, with golden hairs, which are 

 very dense on the apical segments. 



Legs ochraceous with brown scales, scantily set on the femora, 

 so that they appear dull ochraceous ; the tarsi are darker, especially 

 on the hind legs, which have the apices of the joints banded with 

 ochraceous ; to some extent this banding may be seen in the fore and 

 mid legs ; ungues equal, simple, deep brown, large for an Anopheles. 



Wings unspotted, with yellowish veins and pallid scales ; fork- 

 cells rather short, the first sub-marginal longer and narrower than 

 the second posterior cell, their bases nearly level, the stems longer 

 than the cells ; supernumerary and mid-cross veins apparently in 

 one line, the posterior cross-vein about three times its own length 

 behind the mid-cross vein ; halteres ochraceous. 



Habitat and observations. Mr. Theobald says the specimen 

 is " evidently from Goa," and that it was given to him by Captain 

 Liston. This is incorrect. It was captured at Ennur a small 

 village on the East Coast about ten miles from Madras and sent 

 to Mr. Theobald by Dr. Stephens. 



The markings on the palpi must have faded somewhat by the time 

 the specimen reached Mr. Theobald, for in the fresh state three white 

 bands were distinctly present a very broad apical one extending over 

 nearly the outer half of each palp, and two very narrow basal ones.
