in the sixth segment; faint, transverse bands, leaving the sutures indefinitely 

 lighter. There are no median hairs, but several long ones on each side near the sub- 

 marginal bands; last segment entire, truncate or very slightly concave, with sides 

 rounded; a row of short hairs across the posterior margin of the last segment, and 

 a group of strong, close-set hairs on each side on the ventral surface. 



Named in honor of the collector, Dr. Emelia Snethlage of the 

 Museu Goeldi at Para. 



A NEW GENUS AND THREE NEW SPECIES OF PHORIDCE 

 FROM NORTH AMERICA, WITH NOTES ON TWO 

 RECENTLY ERECTED GENERA (CREPIDOPACHYS 

 AND PRONOMTOPHORA ENDERLEIN).

Dr. G. Enderlein in describing (Stettiner entom. Zeit., 1912, 

 p. 1G) some Phoridse from southern Brazil erected the genus 

 Crepidopachys with the new species longirostrata as type. The 

 legend to the figure on same page, which is presumably that of the 

 wing of this species, indicates that it is C. costalis, Enderlein. 

 Thus costalis is evidently a synonym of longirostrata Enderlein. 

 In his remarks on the affinities of the genus he indicates that it 

 differs from Pronomiophora, Enderlein, 1912, in having the costa 

 thickened. This latter genus is not described prior to the former 

 but at page 46 of the same publication, and therefore ought to be 

 considered as erected on page 16, and on page 46 appear as Pro- 

 nomiophora Enderlein and not "no v. gen." Independent of these 

 trifling errors however I fear that there are some others which are 

 of much more consequence. From the description I am forced to 

 the conclusion that in erecting Crepidopachys and Pronomiophora 

 Enderlein added two quite unnecessary genera inasmuch as both
