16 PEOCEEDINGS OF THE NATIONAL. MUSEUM vol. 80 : art. 10 



synonym is Tachina punctifera Walker, List, p. 728, as I saw from 

 the type. Peleteria iterans takes the place of PeleteHa tessellata 

 Fabricius in North American literature. 



Tachina decisa Walker, List, p. 715. Coquillett (p. 143) placed 

 this in the genus Echinomyia. The species is almost unmistakable, 

 and he undoubtedly had the right one, and I think it belongs to the 

 genus Jurinella. The generic reference requires a rather long dis- 

 cussion, which I postpone for another occasion. I saw the type. 



Tachina degenera Walker, List p., 732. Coquillett (p. 144) 

 placed this in his Echinomyia {= F dbi'^iciella Bezzi of Tothill's re- 

 vision) as a synonym of E. algens Wiedemann. Major Austen,*^" 

 however, examined the type and placed it in Ernestia, finding the 

 eyes to be hairy. I did not see the type and am unable to add further 

 details, 



Tachina signifera Walker, List, p. 708. Coquillett (p. 145) 

 referred the species to the genus EpaJpns Rondani. I did not see the 

 type, but it is hardly necessary, for of all Walker's species this is 

 the easiest to identify. It would be almost impossible to mistake it 

 within the area where the type was taken (Nova Scotia). As to 

 the proper genus for signifera^ Townsend in his Peruvian collecting 

 and later has brought to light a world of related forms without 

 palpi. He has reported on his examination of the type of signifera 

 in Revista Ent., vol. 1, p. 167, 1931, where he refers the species to 

 his genus Argentoepalpus^ of which the type species is Epalpus 

 niveus Townsend, from the Peruvian Andes. The genus was de- 

 scribed in Insecutor Inscitiae Menstruus, vol. 6, p. 178, 1918, and 

 the type species in the same journal, vol. 2, p. 136, 1914. I have 

 compared niveus and signifera and agree with this reference. 



Tachina finitinia Walker, List, p. 707. Placed by Coquillett 

 (p. 146) as a synonym of Bomhyliomyia ahrupta Wiedemann. I did 

 not see the type, and it has not been reported upon; it is, however, 

 a very recognizable species, which could hardly be mistaken, so I 

 accept Coquillett's specific determination. Townsend ®^ has made 

 ahrupta (of which I have seen the type) the type of Bonibyliopsis^ 

 new genus. I find, however, that the species is so much like the 

 genotype of Hystricia that it may very well be left there, so I call 

 the species Hystncia abrupta Wiedemann.
