PLATE XXII 



Fig. I. Peridroma serano Sni. White Mts., Ariz. $. 



Agrees well with the description and is a very distinct form. 



2. Tryphaena (Rhynchacrotis)crenulata Sm. Pyramid Lake, Nev. 9- 

 We take it that this specimen belongs to this species ; great variety is 



shown in the costal markings, and we confess to an utter inability, in spite of 

 much material, to provide specimens for all the names in this group, which at 

 present are supposed to represent species. 



3. Trichorthosia parallela Grt. White Mts., Ariz. $ . 



4. Trichorthosia parallela Grt. White Mts., Ariz. 9 . 



5. Aleptina inca Dyar. Christmas, Gila Co., Ariz. $. 



6. Aleptina inca Dyar. Redington, Ariz. 9 . 

 Agrees with type in Collection Barnes. 



7. Tarache ARELOiDEs B. & McD. White Mts., Ariz. Type S- 



8. Tarache areloides B. & McD. White Mts., Ariz. Type 9 . 

 g. Euxoa capota Sm. White Mts., Ariz. $ . 



Agrees well with Smith's description. The antennae in the male sex 

 are ciliate; the description was made from females. 



10. Tryphaena (Rynchagrotis) sp. Esmeralda Co., Nev. 9. 



A very pale ash-colored form which it is impossible to place with our 

 present knowledge. 



11. Amiana (Perigea) continens H. Edw. Redington, Ariz. 9- 



A very heavily marked specimen with the median space almost black. 



12. Catabena vitrina Wlk. (syn. termineltus Grt. Candida Sm.) Red- 



ington, Ariz. S . 

 12a. Catabena vitrina Wlk. Redington, Ariz. 9 • 



The synonymy is according to Hampson ; vitrina is a west Indian spe- 

 cies and if necessary to retain a name for the continental form Grote's name 

 will hold. The S occasionally shows traces of the black dash, which is appar- 

 ently always present in the 9 . By error we neglected to number the 9 speci- 

 men in the plate, but call it 12a. 



13. Prothrinax luteomedia Sm. Gila Co., Ariz. 9 . 

 Agrees with co-types in our possession. 



14. OxYCNEMis advena Grt. Redington, Ariz. 9 . 



Agrees with a specimen compared with type in Neumoegen collection 

 by Dr. Barnes. The white shading is variable and in the specimen figured is 

 more diffuse than usual; the figure appears too pale owing to underprinting, 

 but the type of maculation is readily distinguished. 



15. Peridroma serano Sm. White Mts., Ariz. 9. 



16. Agrotis (Noctua) amia Dyar. White Mts., /\riz. $. 



Agrees with a specimen compared with type in U. S. N. M. The 

 ground color of our specimen, which represents apparently the Arizona form 

 of piscipellis Grt., (we have several others) is deep, rich red-brown and the
