124 EHOPALOCEEA. 



We have two male specimens only of this species, both taken by Mr. Champion at 

 Bugaba. The differences between these examples and the type of A. dismorphites are 

 pointed out above, but it is possible that they are due to the differences of sex, though 

 we hardly think so. 



4. Archonias nigrescens. (Euterpe nigrescens, Tab. LIX. figg. 3, 4.) 

 Euterpe nigrescens, Salv. & Godm. Ann. & Mag. Nat. Hist. ser. 4, ii. p. 149 \ 



A. dismorphiti quoque similis, sed anticis litura in cellula, altera submediana, angulum analem versus fureata, 

 ferrugineis, posticis area interna (prseter venis) coloris ejusdem ; subtus ut supra, sed dilutioribus, area distali 

 nigro reticulata et punctis submarginalibus albis notatis. 



Bab. Guatemala, Polochic valley (F. I). G. & 0. S. x ), Mirandilla (Champion). 



This species likewise is only known to us from two examples : the first, which we 

 now figure, was sent us by one of our collectors from the Polochic valley ; the second 

 was taken by Mr. Champion at Mirandilla, on the Pacific slope of the Volcan de Fuego, 

 at an elevation of about 1600 feet above the sea. 



In the distribution of the black markings on the secondaries this species resembles 

 A. eurytele more than either of the two preceding, but the border is wider, and beneath 

 the large costal spot is completely united to the black outer border, and the primaries 

 on the upper surface have the rusty colour more restricted. 



EUCHEIRA. 



Eucheira, Westwood, Trans. Ent. Soc. i. p. 38, t. 6 (1836). 



The single species of this genus has much the appearance of a Catasticta, but, besides 

 the peculiarity of its habits described below, it has many important points of structural 

 difference. The subcostal of the primaries emits two branches before the end of the 

 cell and one beyond it : there is a distinct upper discocellular in the male, so that the 

 upper radial does not directly join the subcostal ; in the female it does so, and the 

 upper discocellular is absent. The second and third joints of the palpi together are 

 shorter than the basal joint; the terminal joint is rather slender, subcylindrical, and 

 shorter than the second joint. The antennas have a very distinct club. The secondary 

 male organs do not materially differ from those of Catasticta, the harpagones being 

 simple lobes and the tegumen bearing a short blunt central spine. 



The bursa copulatrix of the female has no spiny chitinous patch. 



1. Eucheira socialis. 



Eucheira socialis, Westw. Trans. Ent. Soc. i. p. 38, t. 6 1 ; Staud. Ex. Schmett. p. 26, t. 16 s . 



Alis fuscis, anticis margine costali et macula in cellula albidis, fascia communi maculosa ultra cellulam, a 

 costa anticarum ad marginem internum posticarum, serieque punctorum marginibus propioribus, coloris 

 ejusdem: subtus multo dilutioribus. anticis maculis omnibus majoribus, striga ad cellula basin albida; 

 posticis maculis fere obsoletis.
