THYMELICUS. — OATIA. 481 



Leconte*, of which we possess a long series from various localities in the United 

 States, can be separated from the present species; they have the genitalia of the 

 males similarly formed. The spots on the underside of the secondaries of the male of 

 T. vibex vary in size : in some specimens they are as large and dark as in T. brettus, 

 and in others quite small and reddish, as in T. stigma (Skinner). The females are 

 very like those of T. athenion, from which they may be distinguished by the absence 

 of the dark fascia on the secondaries beneath. T. vibex is also very like Hylephila 

 pkylceus, from which it may be separated by the longer crook to the antennal club and 

 the non-dentate fuscous margin to the secondaries in the male ; the females of the 

 two species are very differently marked. A pair of T. vibex from Rincon, Guerrero, 

 are figured. For the genitalia of the male, see Tab. XCIII. fig. 14.

Alls fuseis, stigmate magno nigro ; anticis maculis duabus utra stigma, duabus marginem exteriorem pro- 

 pionbus, punctis tribus minutis in linea transversa subapicalibus, omnibus evanescentibus, sordide albis : 

 subtus griseis ant flavo-griseis fuseo irregulariter marmoratis ; posticis distinete transfasciatis, maculis 

 paginae superioris magis obviis ; ciliis flavo-griseis. 



$ . Alis fuseis, anticis punctis subapicalibus tribus in linea transversa, maculis quatuor aut quinque in serie 

 sinuosa obliqua a medio marginis interioris apicem versus extendente sordide albis : subtus mari similis, 

 sed alis pallidioribus.

We have a very large series of this insect, ranging from Northern Mexico to Brazil. 

 Our specimens agree well with Hiibner's figures, except that the males have the light 

 spots on the primaries less distinct. T. athenion is not unlike Catia druryi, but the 

 males have more pointed primaries and differently-formed genitalia : for these latter, 

 me Tab. XCIII. rig. 17. 



CATIA, gen. no v. 



We take Hesperia druryi, Latr. ( = Thymelicus cetna, Scudd.), as the type of this 

 genus, and include in it H. misera, Luc. ( = Pamphila mago, H.-S.), Pamphila 

 ravola, G. & S., and an unnamed species from Jamaica in our collection. Scudder, 



* The insect figured as a male of this species is a female, as has been noticed by Scudder and others.
