ART. 10 walker's north AMERICAN TACHIISriDAE ALDEICH 11 



the bristles on facial ridges. Third antennal joint long and wide, five times the 

 second, upper angle prominent ; arista straight, thickened to beyond the middle. 

 Antennal groove deep with sharp edges. Palpi blackish. Pollen of the narrow 

 parafacial rather dark, very thin pollen on parafrontals, which look black. 

 Mesonotum with indistinct stripes. Dorsocentral 3 ; sternopleural 2, 1 ; scutel- 

 lum with 3 lateral, one rather long apical in poor condition. Abdomen shining 

 black, bases of second, third, and fourth segments with band of whitish pollen ; 

 venter almost wholly shining in side view, as deep close to the apex as at base. 

 Mid tibia with two very distinct bristles on outer front side ; hind tibia with 

 sparse bristles on outer side, not ciliate. Wing subhyaline, fourth vein with 

 rounded, rectangular bend, then very concave, just closing the apical cell barely 

 before the extreme apex ; hind cross vein erect, almost in middle between an- 

 terior and bend ; first vein bare, third with two hairs. 



Tachina addita Walker is the female of this, and is so placed by 

 Major Austen. 



The species may be left in Lypha until further material is found or 

 the related forms revised. 



Tachina addita Walker, Insecta Saundersiana, p. 290. Placed by 

 Coquillett (p. 105) as a synonym of the preceding, and I found that 

 Major Austen had made out the same synonjany from the types, with 

 which I fully agreed. The locality was " United States." 



Tachina antennata Walker, Insecta Saundersiana, p. 298. Co- 

 quillett (p. 105) lists this as unrecognized, perhaps a Phorocera. I 

 did not see the type, and nothing has been published upon it as far as 

 I know. The description indicates a very recognizable and remark- 

 able form, if the statements can be relied upon ; briefly, it has the eyes 

 hairy, facial ridges bristly, and third antennal joint greatly widened, 

 twice as wide as long; palpi and antennae black. Several species of 

 North American Tachinidae are known with very wide third anten- 

 nal joint in the male, but all of them that I can find in the collection 

 have bare eyes and bare facial ridges. 



Tachina ancilla Walker, Insecta Saundersiana, p. 299. Co- 

 quillett (p. 106) placed this in the genus Frontina^ but he had the 

 wrong species. I found the type to be the same species that Town- 

 send described as Pseudornyofhyria indecisa.^^ Townsend suggested 

 this synonymy in 1918.^'^ Major Austen ^® referred Walker's type to 

 the genus Frontina. I referred indecisa to the genus 7'achinophyto 

 (regarding Pseiulomyothyria as a synonym of the latter) .^^ 



Coquillett's species, which he mistook for ancilla, has been pro- 

 vided for by Townsend,^'' who named it Frontiniella parancilla, new 

 genus and species (by misprint pararcilla) . Townsend compared the 

 new genus with the European genotype of Fi'ontlna; if he had com- 

 pared with AchaetoTieura his differences would have disappeared
