NOTES ON THE ETHIOPIAN FRUIT-FLIES — I. 233 



It is very doubtful whether Ceratitis penicillatus, Bigot (Ann. Soc. Ent. France 

 (7) i, 1891, p. 381 ; Froggatt, Report 1909, p. 108), from W. Africa, Assinia, 

 belongs to the present genus. 



VII. PARDALASPIS, gen. nov. 



This new genus corresponds to the 4th section of Ceratitis on p. 277 of my above- 

 quoted paper of 1909. It contains rather numerous species, which in the male sex 

 are very easily recognizable by the simple frons and the simple middle legs. The 

 wing pattern is mostly of a pale yellowish colour, but it is sometimes infuscated, 

 and it varies from that of the type of Ceratitis, s. str., to that of Pterandrus (viz. 

 with a separated costal band), and even to that of Trirhithrum (viz. with the middle 

 band united to the marginal one). 

 Type : Trypeta punctata, Wiedemann, 1824. 

 The Ethiopian species may be distinguished as follows : — ■ 

 1(16). Wings with the band over the hind cross- vein quite isolated. 

 2(13). The black spots cf the scutellum are very broad, quadrate or rectangular, 



closely approximated, and covering almost the whole surface. 

 3(12). Last portion of the fourth longitudinal vein destitute of an oblique dark 



streak across its middle. 

 4(5). Wings broad, with strikingly developed basal streaks and dots and with 

 the bands much infuscated ; head of male with a peculiar and striking 

 coloration . . . . . . . . . . . . . . punctata, Wied. 



5(4). Wings with less developed basal pattern and with pale yellowish bands, 

 which at most are infuscated only towards the hind border ; head of 

 male not peculiarly coloured. 



6(7). Thorax destitute of black spots ; species of greater size (8 mm.) 



brSmei, Guer. 



7(6). Thorax with distinct black spots, at least on the sides beyond the suture ; 



size smaller (not over 7 mm.). 

 8(9). Humeri with a distinct black spot ; sides of thorax with black spots before 



the suture ; scutellum with basal black spots . . . . giffardi, Bezzi. *» cosy/ 

 9(8). Humeri and sides of thorax before the suture destitute of black spots ; 



scutellum with no distinct basal spots. 

 10(11). Arista pubescent ; back of thorax whitish, with some small, deep black dots ; 

 wings with the marginal band united at stigma with the basal one 



silvestrii, Bezzi. 



11(10). Arista shortly plumose ; thorax yellowish grey on the back, with broad, 



less distinct dark spots ; marginal band isolated . . morstatti, Bezzi. 



12(3). Last portion of 4th vein crossed over the middle by a well developed, 



oblique, dark streak ; wings short and broad . . . . antistictica, Bezzi. 



13(2). The black spots of the scutellum much smaller and broadly separated, 



the outer ones being more rounded ; the scutellum therefore mo: try 



yellow. 



14(15). Scutellum with three black spots ; wings with the marginal and the basal 



bands wholly separated from the stigma . . . . flexuosa, Walk.
