1924] Notes Upon Surcoufs Treatment of the Tabanidoe 39 
Nemorius Rondani. Monotypic for Chrysops vitripennis 
Meigen, as originally proposed by Rondani. Enderlein gives 
N. singularis Meigen as type. 
Nuceria Walker. Pangonia longirostris Hardwicke was 
designated as type by Coquillett in 1910. Enderlein gives as 
such Tabanus rostratus Linnaeus. 
Ornmatiosteres Enderlein. Enderlein gives as type of this 
new genus Pangonia bifasciata Wiedemann, and places it in the 
Melpiinae, which, according to his key, have the first posterior 
cell open. P. bifasciata, however, has been thus far placed among 
the Pangonius with the first posterior cell closed. 
Pangonius Latreille. Latreille (1810) and Coquillett (1910) 
designated Tabanus proboscideus Fabricius, 1794 {=Pangonia 
maculata PuhvioiViS, 1805) as the type. Enderlein gives as such 
Tabanus marginatus Fabricius, which was not among the species 
mentioned by Latreille when he originally proposed the genus. 
Philoliche Wiedemann. Coquillett designated Tabanus 
rostratus Linnaeus as type in 1910, so that Nuceria Enderlein 
(not of Walker) is an exact synonym of Philoliche. Enderlein’s 
Philoliche j however, with Tabanus angulatus Fabricius as type, 
is entirely different. 
Siridorhina Enderlein. This is an exact synonym of Nuceria 
Walker (not of Enderlein), since both have the same genotype: 
Pangonia longirostris Hardwicke. To judge from the charac- 
ters given in Enderlein’s key, both Siridorhina Enderlein and 
Nuceria Walker appear to equal Corizoneura Rondani and indeed 
Austen includes Pangonia longirostris Hardwicke in Corizoneura 
as defined by him in Bull. Ent. Research, XI, 1920, p. 139. The 
genus should be known as Nuceria Walker, since that name has 
several years priority. 
In his introduction Enderlein mentions several genera whose 
descriptions were not accessible to him. There are, unfortunately, 
a number of others which have also been overlooked, for instance 
such a well-known type as Goniops Aldrich. 
Enderlein’ s paper was issued as a preliminary account, 
pending the publication of a more comprehensive revision of the 
tabanid genera. Meanwhile it is difficult to judge of the validity
