104 Psyche [March-June 
Penelope canicollis Wagler, in northern Argentina. It is most 
probably a species distinct from any recognized in the present 
paper. 
6. Ornithomyia rufiventris Bigot, 1885, Ann. Soc. Ent. 
France, (6), V, p. 243 (no sex; no host. Brazil: Porto Alegre). 
Speiser saw the type and recognized it as a Lynchia, a genus 
which he called Olfersia (1902, Zeitschr. Syst. Hym. Dipt., II, 
p. 169) . It was evidently either L. fusca (Macquart) or L. nigra 
(Perty), most probably the latter. 
7. Lynchia pallidilabris (Rondani). Olfersia pallidilabris 
Rondani, 1878, Ann. Mus. Civ. Genova, XII, p. 161 (no sex; 
no host; Mexico). The size (6 to 7 mm. long) places it among 
the larger species. One can only surmise that it was either 
L. fusca or L. nigra.
