this opening the pupa works its way partly out, then stops and the 

 moth escapes, generally leaving a portion of the empty pupa case 

 protruding from the opening of the cocoon. 



Adult. The only descriptions of the moth published have been 

 the original one by Walker and a still briefer one by Butler. More 

 complete descriptions of the genus Cnidocatupa (new name for 

 Monema, preoccupied) and of the species, are accordingly given here. 



Genus Cnidocampa Dyar. Body short, stout. Head rather small, 

 bent somewhat downward below the axis of the body, frons rounded, 

 densely clothed with scales which project forward above and between 

 the eyes and also in a vertical median line between tiie eyes, forming 

 a T-shaped ridge. A narrow strip just in front of the tongue bare, 

 pale straw yellow, glistening. Labial palpi upturned, nearly as long 

 as the head and thorax together, the first segment short, the second 

 nearly twice the length of the third, thickly clothed with rather long 

 appressed scales. Maxillary palpi absent. Tongue short, naked at 

 base where it separates into two distinct unconnected halves ; appar- 

 ently not functional. Eyes large, nearly hemispherical, their inner 

 margins converging somewhat downward. Ocelli absent. Antennae 

 extending about two-thirds the length of the costa of the fore wing, 

 filiform, the central two-thirds having a very slightly greater vertical 

 diameter than the base and tip ; perceptibly thicker in the male 

 than in the female; without pectinations but quite thickly covered 

 with minute scales. 



Thorax thickly clothed with long hairs and scales which form a 

 pair of long flattened tufts behind on the upper side and extend back- 

 ward over the base of the abdomen. A similar flattened tuft arising 

 in front of the base of the fore wing extends backward beneath it, 

 and another, more erect, passes from the side of the body inward in 

 front of the hind coxa and femur concealing these from in front. 

 Tegulas well developed, extending over the base of the hind wings. 

 Fore wings with a slightly convex costal margin. Outer margin quite 

 strongly, evenly rounded and directly continuous with the slightly 

 less rounded inner margin. Hind wings shorter, but longer than the 

 abdomen, when folded; the base of the fore wing and the base, and 

 that part of the hind wing supported by the internal veins thickly 

 clothed with long hairs. 



The venation characteristic of the family Cochlidiida^, as given by 

 Hampson is : "fore wing with two internal veins : vein ib forked
