446 EHOPALOCEKA. 



Bab. Nicaragua, Chontales (Janson). — South America, from Colombia to Guiana, 

 Lower Amazons. 



We have only a single specimen of this Beliopetes, agreeing with Hiibner's figure of 

 the male of his JJ. j. niwus 3 , which he subsequently called Brontiades petrus \ the 

 female being, perhaps, distinct. The male was also named Leucochitonea laginia by 

 Hewitson 4 . From South America we have several examples, all from the more 

 northern parts. 



The next species is very closely allied to this ; but H. petrus has no dark spots on the 

 middle of the under surface of the secondaries, though B. alana varies somewhat in 

 this respect.

H. petro similis, sed alis posticis subtus macula magna infra cellulam, supra ramos medianos, altera ad 

 medium costae, et duabus marginalibus, una ad angulum apicalem, altera ad medium marginis externi, 

 fuscis.

 Vera Cruz (B. II. Smith), Oaxaca (Fenochio) ; Guatemala, Polochic Valley (F. I). G. & 

 0. S.), Panima, Panzos, San Geronimo, Zapote (Champion) ; Honduras, San Pedro

 Volcan de Chiriqui 4000 to 6000 feet (Champion), Calobre (Arce), Panama (Ribbe, in 

 mus. Staudinger). — South America generally, from Colombia * and Venezuela to Brazil 

 and Paraguay. 



A much commoner insect than II. petrus, and with a wider range both northwards 

 into Mexico and southwards as far as Paraguay. 



There can be little doubt that Reakirt's description, based upon specimens from 

 Insagasuga in Colombia *, refers to this species, and that Plotz's L. adasta 2 also belongs 

 to it. Of the latter we have a specimen given us by Herr Semper with Plotz's name 

 attached to it. It is rather small, and has the subapical band of the primaries very 

 distinct, but it otherwise agrees in the main with our large series. 



The male genitalia do not differ materially from those of H. nivella and H. macaira, 

 but the lower lobe of the harpes is wider, and the upper smaller and less prominent.
