A damaged specimen is in the collection which seems to belong to this species or 

 to a ver}^ closely allied form. It shows six scutellar bristles, the intermediate being 

 a little smaller ; the wings are not as broad as in the Trj^paneinae of the Eutreta 

 group with which it has no affinity, the occipital row of black bristles being very dis- 

 tinct. The arista seems to be, as in the preceding, scarcely pectinate only on the 

 upper side ; only a lower or., black ; the two superior or., the pvt. and the inner vt. 

 are yellow. 



Thoracic and scutellar bristles dark yellowish. Abdomen yellow, with four 

 longitudinal rows of black spots; ovipositor reddish yellow, as long as the three last 

 segments together. 



Wings very like Macquart's figure; a hyahne dot on the stigma ; the hyaline spot 

 at the tip of the wings, between the ends of 3rd and 4th veins, is the largest of all. 

 The discal dots are as follows: three in the same line in the submarginal cell, one on 

 the tip of the first basal ceh, two at the base of the first posterior cell, five in two 

 lines in the discal cell and one in the third posterior cell. First vein not elongated, 

 ending before the small cross-vein; anal cell as in the preceding. Costal bristle 

 distinct. 



I think that stellipennis , Walker, is a true Trypaneine with bare arista, broad 

 wings and an occipital row of stout j^ellow bristles.

9. Acanthoncura, Macquart. 



Macquart, Dipt, exot., iii. 377 (220) 7 (1843). 



Very distinct from the other Oriental genera by reason of the wavy second vein, 

 the bristly ist, 3rd and 5th veins, and the broad head of the male. 



Head very broad, in the male much more so than in the female; face concave, 

 the epistome a little prominent ; eyes round ; antennae inserted on the middle of the 

 eyes, short but almost reaching the epistome, the third joint rounded at the tip, with 

 plumose arista; or. 2, (?); oc. very small; pvt. parallel; genal bristle strong ; bristles 

 of the occipital row black and weak. 



Thoracic chaetotaxy complete; mpl. 2; pt. weak; scutellum with four bristles. 

 Abdomen bristly at the tip; ovipositor short, flattened; male genitalia not promi- 

 nent. Front femora with a row of bristles beneath ; middle tibiae with a single spur ; 

 hind tibiae with a row of short bristles on the outside. 



Wings proportionally short and broad, brownish black with hyaline and luteous 

 spots and indentations. First vein ending opposite the small cross-vein ; second vein 

 wavy; third and fourth a little sinuous, diverging near the extremity; small cross- 

 vein much after the middle of the discal cell ; posterior cross- vein long and perpendi- 

 cular; anal cell drawn out into a triangular point, which is as long as the second 

 basal cell. The costal vein is not so bristly as in Macquart's figure ; first vein with 

 long bristles ; 3rd and 5th veins bristly throughout their length, but the bristles 

 rather short; on the inferior side of the wings the 2nd, 3rd and 4th veins are bristly
