528 MR. H. DRUCE ON NEW HETEROCERA. [May 19, 



JOSIA ORIBIA, Sp. n. 



Form of /. auriflua, Walk. Primaries deep orange-yellow, with 

 the margins narrowly bordered with black. ; secondaries orange- 

 yellow, with the costal, outer, and inner margins narrowly bordered 

 with black. Head, thorax, and abdomen black ; tegulse yellow ;

Expanse 1| inch. 



/TaS. East Peru (TTAjYe/?/). 



A pretty little species allied to J. auriflua, from which it is 

 readily distinguished by the great difference in the secondaries. 



JosiOMORPHA, Felder. 



JOSIOMORPHA STRIATA, Sp. n. 



Primaries deep black, with a central narrow band of buff-yellow 

 extending from the base to near the outer margin, where it is 

 reduced to a point ; secondaries pale buff-yellow, with the costal, 

 apex, and hind margins narrowly bordered with black. ad, 



antennae, thorax, abdomen, and legs all black. 



Expanse Ig inch. 



Hab. Ecuador, Sarayacu {Buckley). 



This species is quite distinct from any with which I am ac- 

 quainted. 



FoRMiANA, gen. nov. 



Primaries long and broad, with the costal margin much arched 

 near the apex, forming a wide hook, giving the appearance of a piece 

 being cut out of the outer margin between the apex and the anal 

 angle, discoidal cell rather long and broad ; secondaries broad and 

 elongated, much rounded-off at the apex. Abdomen extending 

 about one third of its length beyond the wings ; anus tufted with 

 short greyish hairs. Thorax broad, clothed with short black hairs. 

 Head small ; palpi very small, not clothed with hairs. Antennae 

 rather long and deeply pectinated ; legs slender and rather long. 



FoRMiANA MiENADES, sp. u. (Plate XXXII. fig. 18.) 



Primaries deep black, with a large, almost triangular, spot beyond 

 the middle, dentated on the outer margin, and a long streak on the 

 inner margin close to the base, citron-yellow : secondaries bright 

 citron-yellow, with the margins narrowly bordered with black. The 

 underside the same as above. The head, thorax, and upper side of 

 the abdomen black ; the sides yellow, with a narrow black band, 

 on the underside white ; a small yellow spot on each side of the 

 thorax, close to the base of the wings ; tegulae black ; antennae 

 black ; legs brownish black. 



Expanse 1| inch. 



Hab. Bolivia {Buckley). 



This very fine insect is quite unlike any known to me ; it is 

 perhaps best placed before the genus Flavinia, which in some 

 respects it resembles.
