OCYPTERlDyE. 



Ocyptera signal ipennis, S . is probably Ccyptera euchenor, Wlk. 

 Xanthomelana, nov. genus, v. d. W. 



This genus must be very similar to Ocyptera, differing only by the 

 curved, not angulated, fourth vein, and the shortly petiolate apical cell, 

 with the petiole ending at the wing's tip. This name is also preoccupied 

 (Xanthomelcn, Mart., Moll., i860), and may be changed to Xanthome- 

 lanodes. Six species are described, from 4^ to 7^2 mm. long. I hey 

 are: — Xanthomelanodes articulata, & ; X. rubicunda, $(?); X. dor salts, 

 $ ? ; X. trigonalis, <$ ; X. gracilenta, $ $ ; and X. anceps, <$ . 



Phaniid/e. 

 Clinogaster, nov genus, v. d. W. 



This genus must bear a striking resemblance to Hemyda, differing 

 almost wholly in the short petiolate, instead of open, apical ceil, and in 

 the fourth vein being bent at an angle. It belongs apparently in the 

 Ocypteridce, however, and not in the Phaniidce, as indicated by the 

 elongate and incurvate abdomen. 



Clinogaster notabilis, $ , type of the genus, must be very similar in 

 size and appearance to Hemyda aurata. 

 Penthosia, nov. genus, v. d. \V. 



This genus is erected by Mr. van der Wulp for Scopolia satanica, 

 Eigot (Ann. Soc. Ent. Fr., 1S88, p. 254). Mr. van der Wulp has been 

 kind enough to send me a specimen of this species, labelled : " Omilteme, 

 Guerrero, 8,000 ft. July. H. H. Smith." It is a well-marked genus, 

 bearing much structural resemblance to Ocyptera. but differing at once in 

 its well-formed palpi, and its intensely and evenly black colour. It 

 should, I think, also be included in the Ocypteridce. Both this genus and 

 Clinogaster exhibit a closer relationship with Ocyptera than do any of the 

 other American genera of Ocypteridce, by virtue of their petiolate 

 apical cell. 



To sum up : 



The above 4 new genera appear to be quite distinct and valid. The 

 species of Trichopoda appear to be distinct from those previously 

 described. The Hyalomyias, at least the most of them, are doubtless 

 valid species. This is not to be wondered at, since the genus Hyalomyia 

 is rich in forms, It is more remarkable, however, that 4 new species of 

 Jric/iopoda should turn up at this late day, and in a single collection.
