100 PROF. M. BEZZI. 



The present species has a wing pattern very like that of immaculatus, but there is 

 a distinct rounded brown cloud from the end of the anal cell to the hind border ; the 

 facial black spots are well developed ; humeral calli entirely yellow ; a single bub 

 large and rounded hypopleural spot. 



A single male specimen from Umbilo, Durban, 24.viii.1913 (L. Bevis) ; the species 

 was originally described from Bat hurst, Cape Colony.

p. 94, fig. xxvii, and Div. Ent. Hawaii, Bull. 3, 1914, p. 94, pi. viii, fig. xxvii. 



There is some doubt as to whether this species may not be the same as D. sigmoides, 

 Coquillett (1901), from Mauritius. Humeral calH entirely yellow ; a single rounded 

 hypopleural spot. 



The species is common in the Ethiopian region, and has been imported also into 

 South India, living in melons and other cultivated Cucurbit aceae. It was originally 

 described from Erythraea, and has since been recorded from Dahomey, Transvaal 

 and Cape Colony ; I have also specimens from German South West Africa, Windhoek, 

 and from the Sudan. 



In the collection before me it is represented from the following localities : — British 

 East Africa, Nakuru, i.l913 {Dr. B. L. van Someren) ; Uganda {C. C. Gowdey) ; 

 Nyasaland, Mt. Mlanje, 19. v. 1913 (S. A. Neave) ; N. W. Rhodesia, Demere River near 

 Chilanga, 2,000 ft., very plentiful on Citrus fruit tree, 27. v. 1913 (R. C. Wood)\ 

 Zanzibar, 1913 {Br. W. M. Aders) ; Pretoria, 30. i. 1914 {David Gunn) ; Durban, 

 Umbilo, 24. V. 1914 {L. Bevis). 



18. Dacus vertebratus, Bezzi, 1908 ; Silvestri, Bull. Lab. Zool., Portici, viii, 1913, 



p. 93, fig. xxvi, and Div. Ent. Hawaii, Bull. 3, 1914, p. 93, pi. viii, fig. xxvi. 

 Described by me originally from Erythraea and subsequently recorded from 

 KiHmanjaro, French Guinea and Southern Nigeria ; I have also specimens from 

 Senegal. The species is injurious to cultivated Cucurbitaceae. In the collection 

 there are specimens from Nyasaland, Mt. Mlanje, 23. v. 1913 {S. A. Neave) ; S. Nigeria, 

 Ikotekpene, 17. v. 1910 (J. J. Simpson) ; Pretoria, ii-iii.l914 {David Gunn). 



19. Dacus vertebratus var. marginalis, nov. 



Distinguishable from the type only by the brown apical spot being isolated from 

 the fore border, on account of this border being yellowish, not brown. The character 

 of the scapular bristles given in the table seems to be variable. 



Several male specimens from Natal, Estcourt, 17.iii.l913 {R. C. Wroughton) ; 

 N.W. Rhodesia, Mayabuku, 3,400 ft., in house, 7.xii.l913 {R.C.Wood). 



20. Dacus ficicola, sp. nov. (fig. 14.) 



This species has a wing pattern very like that of brevis, but may readily be 

 distinguished by its two contiguous hypopleural spots. 



(J. Length of body, 5-5*6 mm. ; length of wing, 4'9-5'2 mm. 



Frontal band of a dark red colour, with yellow orbits which bear three pairs of black 

 spots ; the lunula and an ocellar dot are also black ; occiput dark brown, with a narrow 

 yellow border, which is dilated below ; face yellow, its two black spots shining and of
