In Vol. II, No. 4 of the “Annals of the Entomological Society 
of America,”’ a number of species and genera of North American 
Tachinids are described as new by Mr. C. H. T. Townsend. 
While working in the National Museum some time ago, I had 
occasion to make a careful study of the types of some of these 
forms, with the results given herewith. 
Paragermaria autumnalis Towns. 
This species has been described by Mr. D. W. Coquillett in Proce. 
Ent. Soc. Wash., VI., p. 186, 1904, as Distichona auriceps. The 
species is a well-marked one and there can be no question as 
regards the specific synonymy. ‘The question of the synonymy 
of the three genera Distichona v. d. Wulp, Pseudogermaria B. & 
B., and Mr. Townsend’s new genus Paragermaria, is a more 
difficult one and I do not care to express an opinion upon it at 
the present time. It must be noted, however, that in the speci- 
mens of this species which IJ have examined, there are a couple of 
hairs below the lowest frontal bristles and a row of similar fine 
hairs extends up the parafacials to a short distance below the 
upper ones just mentioned so that the parafacials cannot be 
termed bare. On this account Distichona auriceps Coqt., will 
not run to the genus Distichona in either the key to the genera 
in Mr. Coquillett’s “Revision,” nor in Mr. Adams’ in Williston’s 
“Manual,” but will run out to Winthemia, from which it is easily 
distinguished by the reclinate ocellar bristles, the ciliate facial 
ridges, the broad cheeks, etc. 
Sisyropa hemerocampae Towns. 
Mr. Townsend gives as a synonym of this species, Exorista 
griseomicans Coq. (non v. d. Wulp), but has apparently over-
