verso-posterior vein,” which he describes in Ornithomyia, is homo- 
logous with the “transverso-discoidal” which he found in Lynchia, 
the second basal cell being merely much lengthened in Orni- 
thomyia. Evidently this has been the source of Speiser’s er- 
roneous assumption that the second basal cell was not closed by 
a cross-vein in Lynchia. 
From the above account it appears that Lynchia Weyenbergh 
is a synonym of either Olfersia Wiedemann ( Feronia Leach; 
Pseudolfersia Coquillett) or Ornithoponus Aldrich ( Olfersia of 
authors, not of Wiedemann.) Although the description is not 
very explicit with regard to the structure of the head, the state- 
ment that there is a small, triangular, somewhat raised plate in 
the ocellar region, can, in my opinion, only apply to a species of 
Ornithoponus. I believe that the name Lynchia will eventually 
be used instead of Ornithoponus. Since the problem will be 
fully solved only with the rediscovery of the type-species, I 
deem it worth while to give a translation of the specific descrip- 
tion also.

“The eyes are of a dark reddish brown color and an orbital, 
nearly black half-circle incloses them on the frontal portion. 
These eyes are large and spherical, and show punctiform facets. 
The antennae and the front are yellowish and at the top of the 
occiput one sees a triangular, dark, somewhat raised plate. On 
the labrum one sees a dark spot. The tip of the first segment of 
the antennae also is nearly black. The thorax is of a dark sepia 
color; the median, raised line is brownish black, and the whole 
shows a yellowish sheen, somewhat metallic, especially on the 
metathorax and along the margins of the scutellum, which latter 
bears hairs along its posterior border. The abdominal segments 
are of the same color, very dark; and their margins have a yel- 
lowish sheen on the articulations. The , veins have the same 
general color, a little grayish, and the wings are very transparent 
and large. The hal teres are dirty white. The claws of the legs
