to mention the difficulty of effecting a compromise between 

 the German and American synopses. 



A genus not included here was described by Marquart 

 (38M411) under the name Blepharit arsis with a type species 

 orttatus, which was figured in Dipteres (Planches Vol.), taf. 

 34, fig. 5. There was a decided discrepancy, however, between 

 the description and the figure, and the genus was left open to 

 ({uestion in the later worJvS of Low, von Roder, and Becker, 

 and will probably never be settled without reference to the 

 original type which was found in Africa and was in the 

 cabinet of M. Viard when seen by Macquart. If there is a 

 distinctive mark of this genus at present available it is prob- 

 ably the long bristles of the hind tarsi. 



Another genwfi, P<'gophila,WAH described by Rondani (r)6R129) 

 with a type species meridionalis, but it differs from Notipliila 

 only in the possession of a somewhat shorter second longitudi- 

 nal vein, and Professor Becker does not regard this as of 

 generic value. 



A subfamily, Lipocliaetinae, was established by Coquillett 

 (96C220) with a single genus and species, Lipochaeta slossovae, 

 to accommodate some specimens taken in Florida. The follow- 

 ing year this insect was relegated to the family Agromyzidae, 

 i^ub family Oclithiphilinae, by Profe>ssor Williston (97W7). 

 Mr. Townsend, in describing his species texensis, states that it 

 belongs to the genus Lipochaeta. ])ut differs from sIossoikw 

 in that "the head is even broader than the thorax, clypens 

 projects fully the length of the face, front almost as wide but 

 usually narrower than the oral opening, scutellum one third to 

 one half as long as thorax, claw\s slender, a little elongate but 

 not large or stout. The third and fourth veins converge toward 

 their tip, but not strongly so." Every one of these characters, 

 except the last, are given by Coquillett as generic and not 

 specific, and every one differs from Mr. Townsend 's species. 

 Suppose this insect belongs to the genus Lipochaeta, even 

 though the description makes this impossible, then the only 

 specific difference we have is the following : 



"The third and fourth veins strongly, converging toward 

 their tips slossonne Coq. 



"The third and fourth veins converge toward their tips, but 

 not strongly so texensis Towns. ' '
