only two terminal spots and without any dorsal spot on the foremng. 

 The submarginal spots of the forewing are dissimilar in shape, and 

 on the hindwing the submarginal row of spots is represented by only 

 one indistinct spot. The female genitaha resemble those of simula- 

 trix, but the signum is of a quite different shape. The specific name 

 is derived from the Greek word nvSpos^ meaning "a red-hot mass."

Idolatteria pyropis Walsingham, 1914, in Godman and Salvin, Biologia Centrali- 

 Americana, Lepidoptera Heterocera, vol. 4, p. 270, pi. 8, fig. 9. 



Female genitalia. — Sinus vaginalis tm-een shaped; lamella 

 antevaginalis narrow, straight cephaHcally. Antrum membranous, 

 broader than adjacent, cyHndrical portion of ductus biu-sae bearing 

 two lateral colliculi. Signum dagger shaped, slightly curved apically; 

 caudal extension of its basis longer than cephalic extension; capitulum 

 semirotundate. 



Type.— Holotype, female (abdomen missing), Volcan de Irazu, 

 Costa Rica, 6000-7000 ft. (H. Rogers; Godman and Salvin CoUection- 

 66225) ; BM. 



Other specimen examined.— One female (genitaha on shde 

 757-Obr.), Monteverde, Puntarenas, Costa Rica, 4600 ft., Feb 28 

 1962 (C. W. Palmer); AMNH. 



Remarks. — No male of this species is known. There are some 

 color differences between the holotype, which appears somewhat 

 faded, and the other specimen examined, due probably to different 

 collection tunes. The antennae, labial palpi, head, thorax, and the 

 wing markings, described by Walsingham as being ''purplish fuscous" 

 or "dark purple," are found by the present author as having these 

 colors in the holotype. In the newly collected specimen they are 

 almost black mth a sHght bluish hue. The head would best be 

 described as being black with a large, cream-white spot on the face 

 and with concolorous cristae externad of the eyes. The patagia are 

 black. The thorax is also black with two anterior, mediolateral 

 yellow streaks becoming pale orange distally; the posterior margin of 

 the thorax is orange; the external cristae of the tegulae are cream 

 white. The abdomen is bluish black with narrow postsegmental 

 bands orange dorsally, whitish laterally and ventrally, and also 

 whitish on the dorsal surface of the tip. The arrangement of the wing 

 spots is approximately the same in both of the examined specimens, 

 although the size and shape of separate spots are slightly distinct. 

 In spite of all the mentioned differences, there are no grounds to treat 

 the above specimens as belonging to two separate species.
