GcoTnctridae of the Argentine Reimllic. 241 
Hindwing slightly paler, without markings, proximally paler than 
distally. Underside nearly without markings, the forewing with 
faint indications of the pattern of the upperside. 
Puente del Inca (W. M. Bayne). Type $ (bred from 
larva, January 5, 1906), and one $ (March 16, 1905), in 
coll. L. B. Prout, one $ in coll. A. F. Bayne. 
The antenna is pointed at apex, but not appreciably 
dilated before it; this character, however, at which Guenee 
so greatly marvelled, is not essential to the genus—it 
does not occur, for instance, in the group of rosida, Dogn., 
Le Nat., 1892, 274 On the other hand, B. otojjhora is 
slightly aberrant in having the lobes of the hindwing 
rather smaller than in most of the species. In this respect 
it comes nearer to some of the Chilian genera. The 
venation, as in many of the allies, is slightly variable, but 
the three which I have studied agree in having the double 
areole ample, very short-stalked with SC^'^, slightly 
nearer to R^ than to Rb disco ?ellulars hardly oblique. In 
the hindwing the $ has C closely approximated to SC 
to near end of cell, connected by the usual bar before 
diverging, SC'^ separate from R^; both ^s have G ana¬ 
stomosing strongly with SC, SC“ and are either connate 
with the radials or shortly (M^ very shortly) stalked.

(^) Aysen River, W. Patagonia. 
Originally described (^) from Orange Bay, in the S. of 
Patagonia, which belongs politically to Chili. Physically, 
too, the genus is entirely Chilian. The species would 
seem to be quite nearly related to some forms of varians, 
Butl., Tr. Ent. Soc. Lond., 1882, 400. It has also, no 
doubt, much in common with amoena, Philippi = ternata, 
Ye\di. = jacintaria. Stand, (nov. syn.), the type of the genus 
Tomopteryx. Whether Tomopteryx can really, as Butler 
says (Tr. Ent. Soc. Lond., 1882, 402), be kept generically 
separate from Pachrophylla, I have not yet been able to
