I have received, in reply to an inquiry, a letter from E. E. 

 Austen who has charge of the collections in the British Museum, 

 and who is qualified to give authentic information, stating that 

 the above facts as to type are correct. 



NEOCELATORIA FEROX WALTON A SYNONYM OF CHAETO- 



PHLEPS SETOSA COQ. 



BY W. R. WALTON, Bureau of Entomology. 



I am indebted to Dr. J. M. Aldrich for calling my attention to 

 the probability of the above mentioned synonymy. A comparison

 original description of the genus or species. 



A NEW ORTALID FLY. 



BY NATHAN BANKS, Bureau of Entomology. 



Pseudotephritis appoximata new species. 



Similar to P. van Say, but larger and marks on the wings different. Head 

 and thorax marked as in P. vau, the same large brown spots, but on thorax 

 the minute brown marks are rather more numerous. On abdomen the third 

 segment is mostly pale, with only minute dark spots, the following seg- 

 ments wholly dark; legs marked as in P. vau. In wings the marks on costa 

 and at tip are black, the others fainter, more yellowish brown; the clouds 

 over cross-veins not connected, that over posterior cross-vein extending 

 toward the cloud below preapical costal spot; and that over the discal 

 cross-vein extending to the middle costal spot, the outer margin of the 

 broad sub-basal cloud is much interrupted at the fourth vein. The pos- 

 terior cross-vein is as near the outer margin as to the anterior cross-vein. 

 The macrochsetse of head and thorax are as in P. vau. Length, 7.5 mm.
