PSYCHE. 



[August 1S93. 



mosa, only the nearly clear spaces of 

 the latter in albofascia form dark, 

 broad, very distinct bands. There are 

 two dark dusky patches on the hind 

 wings. The examples of G. albofascia 

 are more typical of the species (if it be 

 regarded as distinct from ridenda) than 

 those placed under G. formosa. 



The fore wings somewhat luteous-gray at 

 base; on the inner third is a broad black 

 band widening on the costa, and still wider 

 on the internal edge, where it reaches a little 

 beyond the middle of the wing. A clear 

 luteous gray median space, beyond which on 

 the outer third of the wing is a broad black 

 band, between which and the submarginal 

 scalloped line is a gray band. Hind wings 

 with a diffuse broad band on the outer 

 fourth, forming a dark patch on the internal 

 angle, and another in the independent inter- 

 space. On the under side of the wings the 

 dark bands show through, as do the two 

 dusky spots on the hind wings. 



G. Formosa Edwards. — 4 $ , all from 

 Utah. As already stated I regard this 

 as a synonym of G. albofascia, both 

 species being with little doubt climatic 

 varieties of G. ridenda. 



The antennae are well pectinated, rather 

 more so than in G. ridenda. The wings are 

 much paler gray than in ridenda, the hind 

 wings being almost white, but the thorax 

 and abdomen are as in ridenda. Fore wings 

 with black scales at the base, but with no 

 definite lines such as are to be seen in trili- 

 neata and ridenda, but just beyond the base 

 the wing is more or less luteous, as in 

 ridenda. Middle of the wing with a broad 

 pale flesh-colored or luteous band, bordered 

 on the inside by a very distinct black line 

 like that of ridenda, becoming wider on the 

 costa. In the middle of the band is a dark 

 line nearly parallel with the inner one, dilat- 



ing on the veins and all the lines forming 

 distinct dark costal spots. The outer third 

 of the wing gray, with dark scales and with 

 an irregular blackish wavy line, much as in 

 ridenda and rupta. Hind wings whitish, 

 with no lines, and with three dark dots on 

 the fringe of the internal angle. The outer 

 third of the wing faintly dusted more or less 

 with fine dark scales. Wings pale whitish 

 beneath ; two blackish costal spots beyond 

 the middle, and costa of both wings speckled 

 with dark scales. A faint diffuse band passes 

 across the hind wings just beyond the 

 middle ; and the margin of both wings is 

 speckled with dark scales. Body beneath 

 pale, and the legs (tarsi) ringed with dark 

 scales. 



After preparing the preceding de- 

 scriptions I find that Mr. Edwards adds 

 to his description of G. formosa the 

 following remark : "It is possible that 

 G. ridenda and G. rupta are forms of 

 one species, and that G. albofascia and 

 G. formosa are forms of another, but I 

 prefer to consider them as distinct until 

 future investigation shall determine 

 their true position." 



G. lintxeri (Grote). Originally de- 

 scribed as a Dasychira ; this is a true 

 Gluphisia, but, with G. severa and avi- 

 macula, belonging to a distinct section 

 of the genus. The $ antennae are pro- 

 vided with long close pectinations ; the 

 body is stout and hairy ; the costa of 

 the fore wings is much more convex 

 than in G. trilineata, and the apex 

 somewhat produced as in G. severa. 



G. wrightii H. Edwards, Ent. amer. 

 ii, 11. April, 1SS6. This species in- 

 habits San Bernardino, Cal. It is very 

 nearG. severa Edwards (Ent. amer. ii, 

 167. Dec. 1886).
