﻿408 ERNEST E. AUSTEN — NEW AFRICAN TABANIDAE — PART III. 



in bush-path, 10 a.m." : all the foregoing taken and presented to the British 

 Museum (Natural History) by Dr. W. M. Graham, W.A.M.S. Two females 

 from West Ashanti have also been examined — one from Tekerri, 24. v. 1911 

 ( T. E. Fell : in possession of the Entomological Research Committee), the other 

 from Sunyani Station, July, 1911 (Dr. W. M. Wade, W.A.M.S.: presented to 

 the British Museum by the Entomological Research Committee). A field-note 

 by Dr. Graham states that in Ashanti this species is "found only in thick 

 forest." From the Sierra Leone Protectorate the Museum possesses the 

 following examples, taken and presented by Major A. Pearse, R.A.M.C.: — 

 two specimens from Gola Forest, ll.iii. 1909 ; four specimens captured between 

 Mogbaima and Dombolo, 18. iii. 1909 ; one specimen from Dombolo, "on an 

 elephant," 23. iii. 1909. 



As regards differences between Haematopota grahami and H. bullatifrons, 

 Austen, in addition to the distinctive characters upon which stress has already 

 been laid, attention in the case of the present species may be directed to the 

 much greater width of the frontal callus, which is almost in contact with, instead 

 of " widely separated from ", the eyes, the greater length and different coloration 

 of the first joint of the antennae, and the much less extensive development of the 

 grey markings on the main portion of the dorsum of the thorax. From the 

 following species, which may be regarded as in some respects occupying an inter- 

 mediate position between Haematopota grahami and H. bullatifrons, H. grahami 

 may be distinguished by the above-mentioned characters in the frontal callus and 

 first joint of the antennae, by the absence of a third (median) grey stripe on the 

 dorsum of the thorax, the greater extent of the grey area on the scutellum, and, 

 in the wing, by the greater length of the stigma and by the sinuous mark near 

 the apex being interrupted before reaching the middle of the second submarginal 

 cell. 



Haematopota daveyi, sp. n. 



Q.— Length (2 specimens), 11 to 12*4 mm.; width of head, 3'8 to 4 # 2 ram.; 

 width of front at vertex, 1*25 to 1*4 mm. ; length of wing, 9*5 to 10*25 mm. 



Larqe or moderately large, dark-coloured species, closely allied to, and in some 

 respects intermediate between, the foregoing species and H. bullatifrons Austen. — 

 Head and all cephalic structures and markings practically as in H. bullatifrons, 

 though interval between each lateral extremity of frontal callus and corresponding 

 eye is narrower ; dorsum of thorax dark brown with grey markings, scutellum with 

 a large grey spot entirely surrounded with brown, either in centre of disc or extend- 

 ing closer to posterior than to anterior margin ; dorsum of abdomen clove-brown, 

 with conspicuous light grey hind borders to all segments, as well as other light grey 

 markings ; wings sepia-coloured, light markings agreeing generally with those on 

 wings of H. bullatifrons, but apical sinuous mark sometimes interrupted or nearly so 

 in middle of second submarginal cell, and median rosette and markings in discal 

 cell as in foregoing species ; legs as in foregoing species, except that proximal 

 two-thirds of anterior surface of front femora, and proximal three-fourths of hind 

 femora are grey and clothed, for most part at least, with whitish hair, while fringe 

 of hair on outer side of hind tibiae is, if anything, somewhat longer, and pale area 

 on first joint of hind tarsi is ligliter in colour and more extensive.
