ON THE DIPTEROUS GENUS EUSIPHONA
Published online by Cambridge University Press: 31 May 2012
Extract
At the time of establishing this genus, in my recent revision of the Tachinidae, I had only two specimens before me; in both of these the wings are bent backward in such a manner as to prevent a critical examination of the longer calypteres, but as the specimens otherwise agree quite closely with the Tachinid genus Gymnophania, I concluded to place the present genus next to it. The recent examination, however, of a perfect specimen from Mr. Charles Robertson, of Carlinville, Illinois, reveals the fact that the lower calypteres are extremely small, being, in fact, rudimentary, and this genus must therefore be transferred from the Tachinidae to the super family Aclyptrata. In all the essential characters it agrees rvith the family Agromyzidae, and its proper place is evidently in the vicinity of the genus Desmometopa, from which it will be readily recognized by the strongly convex front and the excessively long, bristle-like proboscis.
