13. VI. (J. Boll; Stn. Coll., & Mus. Wism.). Central America—MEXxIco: TABASCO = 
Teapa, III. (1. H. Smith). 
A single specimen, in poor condition, from Teapa (65694), is easily recognised as 
iridipennella. 
Chambers ©™ rightly sunk aphroditeella Chmb. as a synonym of iridipennella Clms. 
(his type of aphroditeella, in the Museum of the Peabody Academy of Science, Salem, 
Mass., was examined in 1881 and this identification confirmed), but proserpinella Frey 
and Boll was wrongly regarded as synonymous by Busck ai—?) We have compared 
the type of proserpinella with specimens of iridipennella determined by Clemens, and 
now recognise proserpinella as a good species, separable from iridipennella without 
difficulty by the distinct large iridescent dorsal streak, intermediate between the second 
and third costal streaks; in ¢ridipennella this streak is replaced by four small iridescent 
spots arranged rectangularly, that on the dorsum, sometimes less conspicuous than 
those above it, being preceded and followed by others in a more or less continuous 
series parallel with the termen.

Chambers “) remarked that the single specimen of iridipennella received from Belfrage, from 
Bosque County, Texas, differed in having “a less number of the blue spots” than any he had seen : 
this specimen was doubtless proserpinella, of which there is a specimen in the Stainton Collection, 
also received from G. W. Belfrage. 
Strobisia proserpinella has not yet been met with in Central America, but Boll took both species 
at Dallas (Texas) and it may be expected to occur further South. ] 
2. Strobisia walkeri, sp. n. 
Antennae leaden grey. Palpi pale leaden grey. Head and Thorax leaden grey. Forewings with a leaden 
grey basal patch, merging outwardly into tawny purplish fuscous, which reaches to one-third and is 
bounded on the costa by a cuneiform white costal streak, while from its lower half it sends obliquely 
upward a sharp steel-grey tooth-like projection into the deep brownish orange band which succeeds it ; 
from each extremity of the white costal streak a dark steel-grey point also projects outward; the broad 
orange band into which these project is bounded a little beyond the middle of the wing by a rather 
oblique bright steel-grey fascia, narrowly margined on either ‘side by black, and rather wider on the 
dorsum than on the costa; this again is succeeded by a deep reddish orange fascia, narrower than 
the preceding orange band, but somewhat produced outward on the dorsum ; above this dorsal extension
