296 ERNEST E. AUSTEN — NEW AFRICAN 



see below), and a fourth species, at present undescribed, of which specimens have 

 been received from the East Africa Proctectorate by the British Museum (Natural 

 History) and the Imperial Bureau of Entomology.* From Haematopota sanguin- 

 aria the species just described is distinguishable, at least in the female sex, by 

 reason of its larger size and generally darker coloration, and further by the third 

 joint of its antennae being brown instead of tawny-ochraceous, by the distal portion 

 of its scutellum not being ochraceous-buff and by the stigma being much darker. 

 From the female of Haematopota edax that of H. inglaviosa may be distinguished 

 owing to its paler frontal callus, and to the much less elongate shape of the 

 expanded portion of the third joint of its antennae. The undescribed Haematopota 

 from the East Africa Protectorate mentioned above is closely allied to H. inglaviosa, 

 to which, in the female sex at any rate, it presents a deceptive resemblance, agreeing 

 with it in size and general appearance. The East African species is however 

 distinguishable from that described above owing to the first and third joints of its 

 antennae being somewhat more elongate, to the pale markings of the wings being 

 less distinct, and to the distal portion of the front tibiae being slightly less 

 thickened and not so dark, i.e., brown instead of clove-brown. 



Haematopota edax, sp. n. 



Q. — Length (6 specimens) 9*4 to 10*5 mm. ; width of head 3 to 3*4 mm. ; 

 width of front at vertex 0*8 to 1 mm. ; length of wing 8*2 to 9 mm. 



In general appearance closely resembling smaller and paler specimens of fore- 

 going species, but distinguishable owing to greater length of antennae, due to more 

 elongate and tapering shape of expanded portion of third joint (as viewed from 

 side). — Front narrow and of nearly uniform width (^usually appearing narrower 

 than in foregoing species), frontal callus dark brown ; dorsum of thorax sepia- 

 coloured, with grey or yellowish-grey markings as in foregoing species : abdomen 

 tapering to distal extremity, dorsum mummy-brown with yellowish-grey markings 

 exactly like the grey abdominal markings in foregoing species (see fig. 4) ; wings 

 light sepia-coloured, stigma dark brown, elongate and distinct ; front tibiae clove- 

 brown, with a single pale band as in Joregoing species. 



Head : front sepia-coloured, lateral margins and expansions from them sur- 

 rounding lateral frontal spots yellowish grey, usual dark patch on vertex also 

 often triangular in outline owing to a yellowish-grey border, the two sides of 

 which run inwards and forwards tdl they meet in front of median frontal spot, 

 while patch itself is divided by a narrow grey median stripe ; median frontal 

 spot usually indistinguishable, lateral frontal spots small, in contact with eyes ; 

 front clothed on sepia-coloured area witli minute black or dark brown hairs, and 

 on yellowish-grey area between each lateral frontal spot and callus clothed with 

 pale-yellowish hairs : frontal callus extending from eye to eye, moderately deep 

 and shaped as in foregoing species ; median clove-brown spot below callus, small 

 but distinct, usually almost divided into two by a triangular indentation in its 



* Also belongiDg to this group are Haematopota {Parliaematopota) cognata, Griinb., and a new 

 species found, like the latter, in German East Africa ; both of these, however, are at once dis- 

 tinguishable from the species mentioned above owing to the presence of a second pale band on the 

 front tibiae.
