6(7). Frons with a transverse brown stripe ; humeral calli dark brown ; white 

 mesopleural patch vertical ; front femora entirely black . . tritea, Walk. 



7(6). Frons with a longitudinal brown stripe ; humeral calli white ; mesopleural 

 patch longitudinal ; front femora whitish at apex pseudotritea, sp. nov. 



8(1). Second longitudinal vein distinctly wavy ; wings with basal streaks ; 

 scutellum rather convex and shining black ; abdomen with two broad 

 transverse bands of whitish pollen. . superba, sp. nov. 



1. Carpophthoromyia vittata, Fabricius, Wiedemann; Loew, Berl. ent. Zcits., 



v, 1861, p. 262, pi. ii, fig. 3. 

 Originally described from Guinea, Loew has it from Senegal, and Austen records 

 it from East Africa, Delagoa Bay, and from Natal, Malvern.

2. Carpophthoromyia scutellata, Walker, Ins. Saund.,iv, 1853, p. 384, pi. viii, fig. 5. 



Described with a query from Senegal, and recorded by Austen from Sierra Leone. 



3. Carpophthoromyia tritea Walker, 1849 ; Austen, Bull. Ent. Res., i, 1910, 



pp. 72 & 76. 

 Described from Sierra Leone, and not found subsequently. 



4. Carpophthoromyia pseudotritea, sp. nov. (Plate v, fig. 1). 



Ceratitis tritea, Bezzi, Bull. Lab. Zool. Portici, vii, 1913, p. 25, fig. 2 ; Silvestri, 

 I.e., viii, 1913, p. 69, fig. 14. 



Closely allied to the preceding species, but easily distinguished by th£ characters 

 given in the table. 



$ 9- Length of body, 5-6 mm. ; of ovipositor, 1 mm. ; of wing, 5-6 mm. 



In my previous papers I have referred the present species to tritea, Walker, with 

 a doubt, owing to the character of the dark brown humeral calli as indicated by 

 Mr. Austen. I have never seen the true tritea. 



Now Dr. G. A. K. Marshall has compared the present specimens with the type in 

 the British Museum, and has found that they belong to a distinct species. It differs 

 in having the frons pale yellowish, with a brown longitudinal stripe, instead of being 

 pale brownish on the upper half and whitish on the lower half, thus forming a 

 transverse band. Besides, the humeral calli are white (not dark brown), and the white 

 mesopleural patch is longitudinal (not vertical) and twice as long as deep. The 

 front femora are whitish at the apex and the four posterior tibiae are entirely 

 whitish (not brownish on the basal half). The hyaline indentation after the stigma 

 on fore border of the wings is much shorter, ending a little beyond the 3rd longi- 

 tudinal vein, instead of being continued backwards into the base of the 3rd posterior 

 cell. 



Type-^ from Gold Coast, Aburi, 1912-13 (W. H. Patterson) ; type $ from Aburi, 

 April-May 1911 (L. Armstrong) ; and some additional specimens from South 

 Nigeria, Agege, 17th April 1914 (Dr. W. A. Lamborn). I have seen the specimens 

 collected in South Nigeria, Olokemeji, by Prof. Silvestri, bred from fruits of 

 Pyrenacaniha vogeliana.
