424 EHOPALOCEEA. 



Eab. Mexico, Atoyac (E. E. Smith), San Lorenzo and Omealca near Cordova 

 (M. Trujillo), Teapa (E. E. Smith) ; Guatemala, Choctum (F. D. G. & 0. S.), Chiacam, 

 Panima, Zapote (Champion); Nicaeagua, Chontales (Belt); Costa Rica (Van Patten), 

 Santa Clara Valley (Zurcher).— South Ameeica, from Colombia to Guiana, the Amazons 

 Valley, Brazil, and Paraguay. 



We have many specimens from Mexico and Guatemala of this common species, 

 agreeing with Hiibner's figure in having the secondaries beneath dark to the outer 

 margin. The species spreads far beyond our region, having been found by Bates in 

 the Amazons Valley, by Whitely in British Guiana, and by Herbert Smith at Chapada 

 in Matto Grosso. We have also a specimen from Paraguay sent us by Mr. Perrens. 



In altitude D. phalamoides reaches from near the sea-level to a height of upwards of 

 4000 feet in the mountains. 



The male genitalia have a tegumen with a central depressed hook, at the base of 

 which, one on either side, are two divergent points : the harpes are not symmetrical ; 

 the right side ends in a short lobe rounded at its upper corner ; the left side is much 

 more elongated and straighter, and the terminal portion finely serrate along the ventral 

 surface. (See Tab. LXXXVIII. fig. 17.) 



2. Diphoridas palpalis. (Tab. LXXXVIII. figg. 18, 19 <y .) 



Hesperia palpalis, Latr. Enc. Meth. ix. p. 791 \ 



D. pluilcenoidi similis, sed postieis subtus dimidio anali albicantibus distinguendus. 



Eab. Panama, Bugaba, David (Champion), Chiriqui (Arce). — South Ameeica, Amazons 

 Valley and Brazil to Entre Pios. 



Latreille's description of this species is very meagre and hardly recognizable, but we 

 use the name in deference to a named specimen kindly lent us by M. Mabille. 



1). palpalis only differs from D. phalamoides in having the secondaries nearly white 

 towards the anal angle beneath. Its range is included in that of its close ally, and 

 though extending quite as far south does not seem to penetrate into our country beyond 

 the State of Panama. 



GORGYTHION, gen. nov. 



Eelias pyralina, Moschl., does not fit satisfactorily into any of the foregoing genera. 

 The palpi are prominent, much as in Camptopleura, but not nearly so long and drooping 

 as in Diphoridas, to which otherwise it has some general resemblance. The outer 

 margin of the primaries is not so rounded, these wings being more pointed. There is 

 no costal fold. 



Capt. Watson placed G. pyralina in his second section of Pythonides, in which the 

 hind tibia? are said to have only the terminal pair of spurs. This observation is not 

 borne out by our prepared specimens, as both pairs of spurs are distinctly visible.
