is Sarcophaga Iherminieri Robineau-Desvoidy ;^^ he described it 

 from Carolina as a Mj^ophora. The identity of communis with 

 pallinervis was well established from Thomson's description, 

 together with specimens of both sexes from Honolulu; it was men- 

 tioned by Hall.^- 



jSarcophaga ohtusifrons, p. 536. 



Two females, Galapagos Islands. These belong to the Oxijsar- 

 codexia group, in which females are verj^ difficult or impossible to 

 place. The United States National Museum has a series of two 

 males and six females collected on the Galapagos Islands in 1899, 

 of which the females agree with Thomson's description and types; 

 we may therefore assume with some confidence that the males belong 

 to ohtusifrons. They are the same as a series from Samoa identified 

 by Malloch as taitensis Schiner ^^ where he shows by a figure slight 

 differences between peltata and taitensis., which I had previously 

 decided to be identical. I believe taitensis is correctly identified 

 here by him. Schiner described the species. ^"^ It has been customary 

 to give the Novara Reise priority over Eugenics Resa ; but Kahl has 

 discussed the point in Annals of the Carnegie Museum (vol. 11,. 

 1917, p. 393), making out that the latter may have appeared in 1868. 

 Taitensis (including ohtusifrons) and peltata are the only species 

 of the Oxysarcodexia group so far known in which the males have 

 any recognizable villosity on the inner side of the hind tibiae. The 

 forceps in peltata are wide in the middle when viewed from behind, 

 while those of taitensis are narrow. 



Sarcophaga 7iohilis, p. 536. 



Two females, Montevideo and Buenos Aires; the male mentioned 

 by Thomson not now in the collection. A synonym of varia Walker 



/Sarcophaga cansscens, p. 539. 



One female, which is the female of his Tricharaea scatophagina 

 described on p. 541. This is a synonym of Wiedemann's Tachina 

 hrevicornis ^^ the type of which I described under the new generic 

 name Mallonotum.^" Walker's fDexia albicans ^^ is also the same ; 

 and Townsend writes me that he also described the genus and species 

 as Leucoravinia quadraticephala.^^ It results from all this that 

 that species should be known as Tricharaea hrevicornis Wiedemann. 

 It belongs to the Sarcophagidae.
