This species is represented in the Maskell collection by two slides — 

 one of a pupa case and the other of a larva. The pupa case is not 

 cleared and is of such a dense black color that it is difficult to make 

 out any detail. The species no doubt, however, falls in this group. 

 Also from a careful consideration of the description and figures of 

 longicomis Zehntner, we believe this species to be identical with 

 barodensis Maskell. 



Larva (fig. 6). — Size 0.5 by 0.3 mm., elongate elliptical; dorsal 

 disk not separated from the submarginal area, though there is a very 

 narrow marginal region of a lighter color than the remainder of the 

 case, which is brown. The margin is almost entire, but there are a 

 large number of irregular indentations varying in depth. These, 

 however, do not constitute a series of teeth. There is a pair of 

 minute setae on the cephalo-lateral margin, and a seta is present on 

 one side of the caudo-lateral margin (fig. 11). (There is none 

 visible on the right side.) Scattered over the dorsum, as indicated, 

 are a number of minute, circular, transparent, pore-like areas. These 

 appear to be the seats of minute spines, but in the specimens at hand 

 it is impossible to verify this excepting in a few cases. 



The vasiform orifice (fig. 7) is subcordate in outline with the 

 cephahc margin straight and the caudal extremity produced into a 

 knob-like structure. The operculum is somewhat similar in shape to 

 the orifice, but much shorter proportionately, and about half fills the 

 orifice. The lingula, which is spatulate and setose, has its tip exposed 

 caudad of the operculum. It is armed with two rather prominent 

 spines. Two purplish eye spots are evident on the cephalic portion 

 of case. 



Pupa case (fig. 1). — Size 2.25 by 1.15 mm., very elongate elhp- 

 tical, and by its shape and size easily distinguished from the other 

 species of the group; color dense black, by transmitted light dark 

 brown, with a lighter suture separating the dorsal disk from the sub- 

 marginal area; vasiform orifice showing lighter than the remainder 

 of the case and the eye spots almost transparent. Margin armed 

 mth a series of teeth (fig. 4) with shallow rounded incisions, from 

 which suture-hke markings extend mesad across the submarginal area. 

 Vasiform orifice (fig. 3) subcordate, almost entirely filled by the oper- 

 culum which obscures the lingula. The orifice is surrounded by a lobed 

 area, and from its caudal extremity a furrow extends to the caudal
