Note.- I dissent from the conclusions of Osten Sacken and Verrall in 



adopting Rondani's name here. In the first reference above, Rondani says, 



" Spec : typ : Musca pyrastri LIN.," and mentions no other species. Hence 



the proper procedure, in case the genus is illy conceived, is to revise its 



definition, rather than to make its type the type of another genus. I here 



use Lasiophthicus as if this had been done, exactly in the sense of Cata- 

 bomba.

VERRALL, Brit. Flies, vm, 334 (Catabomba) ; on p. 619 is a reference (Ent. 

 Mo. Mag., xxxiv, 244) to an alleged rearing of this fly from pupae of 

 a species of Plusia, which is probably an error, as I have reared it from 

 larvse feeding on the grain Aphis, Siphonopliora arc inc.
