COMMENTS ON MR. VAN DER WULP'S RECENT DIAGNOSES 



OF NEW SPECIES OF MEXICAN PHASIID,E, GYM- 



NOSOMATIILE, OCYPTERID/E, AND 



PHANIID^. 



BY C. H. TYLER TOWNSEND. 



Mr. F. M. van der Wulp, the well-known Dutch dipterologist, has re 

 cently published, in the Tijdschriftvoor Entomologie, vol. 35, pp. 1S3-195, 

 short diagnoses of a large number of new species and several new genera 

 of Mexican Tachinidte sens. lat. Of these, there are n new species and 

 4 new genera which belong to the above four groups. Of such well- 

 known and well-worked genera as Trichopoda, there are 4 new species ; 

 of ffya/owyia, 10 new species ; of Cistogastcr, 8 new species! 



This material was received by Mr. van der Wulp from the editors of 

 the Biologij. Centrali-Americana, but too late to be included in his parts 

 on the above groups, which had already been published. These -forms 

 are to be fully described at some future time in a supplement to the 

 Biologia. No localities whatever accompany the short diagnoses. 



I desire to offer the following notes on these species : — 



Phasiim:. 



Trichopoda nitidiventris, S > is described as having the cilia of hind 

 tibia; black with yellow tips. This must be a quite divergent form, since 

 it is the first one known with the tibial cilia varicoloured. It is also very 

 distinct from the previously known forms in having the abdomen shining 

 black with a rufous anus. 



T. a/ipes, <$ , seems to be different from the described species, inas- 

 much as the tip of the wing, as well as the hind border, is broadly 

 hyaline. 



T. squamipes, $ , seems quite distinct in its yellowish rufous scutellum 

 and abdomen. T. histrio^N\k. (trifasciata, Liv. ), is the only species 

 known to me with a yellowish, or other than a nearly black, scutellum.
