2. Subfamily Trypaneinae. 

 I. Section Ceratitininae. 

 3. Anoplomus, n. gen. 



Easily distinguished from any other genus of the subfamily by the absence of 

 the humeral bristle and by the swollen occiput. 



Head higher than broad; face in the middle swollen but flattened, with narrow 

 antennal furrows reaching the epistome ; occiput with very strongly developed lateral 

 swellings ; cheeks rather broad ; eyes very narrow ; antennae not reaching the epis- 

 tome, inserted over the middle of the eyes, the third joint a little pointed at the tip ; 

 arista plumose, the rays being longer at the upper than at the under side; or. 2. 2 ' ; 

 pvt. weak; vt. 2, inner pair very long, the outer weak; no oc. ; no occipital row 

 of bristles ; vibrissal edges not bristly ; genal bristle weak. 



Thoracic chaetotaxy complete, only the hm. wanting; dc. in the middle between 

 the transverse suture and the basis of the scutellum ; a single mpl. ; pt. proportion- 

 ally strong. Scutellum rounded, a little swollen, black-spotted, with four bristles, 

 the apical pair strong and divergent. 



Sixth abdominal segment of the female distinct ; ovipositor about as long as the 

 abdomen, flat-cylindrical; fifth segment of the male with a row of strong bristles on 

 the hind border. Fore femora with a row of bristles beneath ; posterior femora not 

 spinulose beneath ; middle tibiae with two apical spurs. 



The pattern of the wings is of the rivulet type, with some blackish streaks 

 at the base; costal bristle distinct; third vein bristly throughout its length, but the 

 bristles small and scarce ; second and fourth veins straight ; small cross-vein a little 

 behind the middle of the discal cell; posterior cross- vein almost perpendicular; 

 second basal cell not enlarged ; anal cell with the posterior angle drawn out into a 

 short point, not longer than the second basal cell. 



Type: Anoplomus flexuosus. 



The genus Oedemachilus, Bigot, from Madagascar, as figured in Ann. Soc. Entom. 

 France, (3) vii, pi. 13, f. 4 (1859), shows a singular resemblance to the present 

 genus in the shape of the head, and it seems also that the hm. is wanting; but it has 

 no lower fronto-orbital bristles and the neuration is that of an Ortalid.* 



10. Anoplomus flexuosus, nom. nov. 

 (PI. viii, fig. 12). 

 Tephritis fasciventris, Macquart, Dipt. Exot. Suppl. 3, 225 (65), pi. 7, f 7 (1847), not of 

 Macquart, 1843. 



A very handsome, large fly of a black colour, with white patches on the pleurae 

 and two whitish broad transverse bands on the abdomen. I.ength of the male 6-8 

 mm., of the female lo-ii mm. (with the ovipositor). 



' The first number indicates the upper fronto-orbital pairs, the second the lower fronto-orbital pairs. 

 ^ Through the kindness of the late Mr. Verrall, who has compared the type in Bigot's collection, I 

 am now able to state that Oedemachilus is a true Ortalid, without humeral bristle.
