Genus Anopheles. 39 



the inner side as well as the normal long black ones. Thorax 

 frosty-grey in the middle, showing a median dark line and a pale 

 yellowish- brown one on each side of it in front, more or less 

 tessellated behind, and with many small black specks, the sides 

 deep brown, the median pale frosty area contracted in front, so 

 that the lateral brown areas widen out anteriorly ; the thin hair- 

 like scales (hairs 1) brown ; scutellum and metanotum deep brown, 

 border-bristles of former black. 



Abdomen black with deep brown hairs. Legs long and thin, 

 deep brown ; ungues equal and simple, thin and rather long. 



Wings clothed with dense brown stumpy lanceolate scales ; 

 the first sub-marginal cell considerably longer and narrower than 

 the second posterior cell, its base nearer the base of the wing 

 than that of the latter, gradually becoming acute at the base, its

stem about two- thirds the length of the cell \ stem of the second 

 posterior cell longer than the cell ; supernumerary and mid 

 cross-veins close together, the mid a little behind the super- 

 numerary, posterior cross-vein about its own length distant 

 behind the mid. 



Length. — 3 '5 to 4 mm. 



Habitat— Sierra Leone (800 feet) (Major F. Smith, R.A.M.C.). 



Observations. — Described from several perfect $ 's. It is a 

 very dark species coming near A. nigripes, Staeger, but can at 

 once be told by the denser wing scales and banded palpi. The 

 structure of the second antennal segment is also very marked, 

 having a tuft-like appearance. A $? sent by Capt. Grattan, 

 R.A.M.C., shows traces of three minute pale costal spots, but 

 not extending on to the outer costal border, one spot apical 

 where the upper branch of the first fork-cell joins the costa, 

 another on the first long vein just about the middle of the first 

 fork-cell and another still smaller about the middle of the stem, 

 on the first long vein.
