(48 Be. and 52 Be.) killed after 15 minutes; a 56 Be. mixture 

 did not kill within 17 hours. Gasoline did not kill all eggs after 

 54 hours' immersion. 



8. When immersion in any of the heavier oils was followed by a 

 rinse in gasoline, hatching occurred. 



9. Gasoline-soap emulsion was found to have little killing 

 effect on eggs even after 30 minutes' immersion. 



NOTE ON LESKIINE SYNONYMY (DIPT.). 

 BY CHARLES H. T. TOWNSEND. 



Mr. H. E. Smith's paper in Proc. Ent. Soc. Washington, XIX, 

 122-6, calls for correction. My paper in Proc. U. S. N. M., vol. 

 49, 617-33 (wrongly referred to as Smiths. Misc. Colls.), was not 

 intended as a revision of Coquillett's species in their entirety 

 in any given group but simply as a means of erecting genera 

 wherever needed. Hence only genotypes were mentioned. The 

 following is the synonymy of the species mentioned under Leskia 

 in the Aldrich catalogue, exclusive of Wulp's species which must 

 await further material: 



Dexia analis Say belongs without doubt to Dejeaniopalpus T. 



Myobia depile Coq. equals Dexia diadema Wied., which is a 

 Leskiopalpus T. The species ranges from Florida through Mexico 

 to Brazil. L. calidus T. is a northern form. There is a type 

 specimen of depile in the U. S. N. M. from Jacksonville, Fla. 



Dexia flavipennis Wied. is also a Leskiopalpus. It occurs 

 in South America and the West Indies. 



Myobia flavipennis Wulp (nee Wied.) equals Stomoxys cothur- 

 nata Wd. vel sp. aff. and is a Stomatodexia BB. 



Drepanoglossa occidentalis Coq. equals Masicera eucerata 

 Bigot, which is the genotype of Sipholeskia T. 



Myobia gilensis T. is a Sipholeskia and very close to eucerata. 

 It differs, however, in the pale brassy mesoscutum, golden 

 scutellum and distinctly yellowish tegulae, and evidently re- 

 presents a distinct form inhabiting the mountain regions from 

 New Mexico to Chihuahua, while eucerata is the Pacific slope 

 form. 



Myobia thecata Coq. does not belong in this tribe. It is allied 

 to Telothyria Wp. 



Finally, Siphoclytia T. (type, robcrtsonii T.) belongs in the 

 Leskiini; Drepanoglossa T. (type, litcens T.) belongs in the Cro- 

 cutini; Epigrimyia T. (type, polita T.) belongs in the Cylindro- 

 myiini.
