MAMESTRA MUTILATA Smith. 



Two specimens, August 13 (Sandon, Mr. Curric); September 8 

 (Glacier). The two specimens are not closely similar. The male is 

 mutilata Smith, the female ramter'U Smith, but I can not regard them 

 as separate. 



MAMESTRA LOREA Guenee. 



Thirty-eight specimens, June 13, 16, IT, 23, 24, 25, 30, July 2, 8, 

 22. An early species. Eggs were obtained in season, but I could 

 not carry the larvre beyond stage iv, they showed such a persistent 

 tendency to hibernate. They were fed on dead leaves. 



JSgg. — Two-thirds spherical, base round, not flat, easily detached 

 and rolling. Ribs about 40, rather sharply narrow and straight, 

 diminishing at summit where they become low and less distinct. 

 Reticulations scarcel}'^ indicated, cross-striie obsolete; vertex broadly 

 smooth, obsoletely reticulate; micropyle slightl}' raised with crown of 

 small pyriform cells. Pale yellow, later dark red all over the vertex; 

 diameter, 0.7 mm. 



Stage I. — Head rounded, pale brown, eye black. Body robust, 

 normal, joint 12 slightly enlarged. Cervical shield pale luteous; body 

 whitish, linel}^ dusk3',spicular granular. Tubercles small, brownish; 

 setse long, pale, with enlarged tips. 



Stage IT. — Head ])ilobed, erect, pale brown, the vertex darker; 

 width 0.45 mm. Body robust, joint 12 scarcely enlarged; whitish 

 sordid, dark from the alimentary canal, the incisures folded. Dorsal 

 and subdorsal lines barel}^ indicated; tubercles round, black; setae 

 moderate, capitate; feet pale, those of joint 7 a little smaller. 



Stage III. — Head round, dull dark brown, darker shaded centrally; 

 width 0.7 mm. Body robust, flattened, equal; ocherous subdorsall}^, 

 a series of wide dorsal diamond-shaped marks, lighter centrally and 

 cut by a very obscure, pale dorsal line. Sides mottled in brown black 

 like the dorsum. Shields concolorous; tubercles small, l)lack; seta 

 stifl", pale, subcapitate, alternating forward and backward; feet pale, 

 the pair on joint 7 smaller. 



Stage IV. — Head round, pale brown, with obscure darker reticula- 

 tions and bauds; width 1 mm. Body robust, flattened, equal, sluggish. 

 Color as before. 



The concluding stages remain to be described. 



MAMESTRA LARISSA Smith. 



One specimen, June 13, and two from Mr. Cockle's collection June 2 

 and 25, 1902, which he has kindly allowed me to keep. Mr. Cockle 

 says the species was not rare in 1902, but it certainly was so in 1903. 

 It is ver}^ close to jjenslHs Grote in appearance.
