ish black, the color in marginal band fading into gray towards anal angle. A black 

 basal blotch, fringes in primaries and secondaries whitish gray, ornamented with 

 dark brown at intersection of nerves; less marked on secondaries. Below: legs and 

 abdomen mouse gray. Primaries and secondaries brownish gray, the basal regions 

 shading into light gray and assuming a whitish tint near anal angle of secondaries. 

 The anterior transverse line on primaries and the marginal and medial bands on sec- 

 ondaries well pronounced. Fringes as above. 



Habitat: New Mexico. Length of body 28 mm. Expanse of wings 

 1 10 mm. = 4.40 inches. 



Types in coll. Prof. F. H. Snow and B. Neumcegen. 



This stately insect has been, for many years, confounded with Sph. 

 lugem Wlk. , which comes from Mexico, although a few specimens have 

 been found in our South-Western States. Lugtns Wlk., is a considerably 

 smaller insect of brownish olive tint, with delineations not so prominently 

 marked, and faint basal blotches. The excellent figure of Mr. Strecker's 

 Sph.lugens Wlk. (H. Strecker's No 13, fig. 12), would do well for Sph. 

 separatus, if the color were changed and the other differences prominent- 

 ly marked. 



Arctia v. Mormonica, N. var. 



This is a beautiful variety of the Incorrupta type. Head, thorax and wings 

 whitish yellow with black markings. The two black dots on prothorax missing and 

 the black stripes on thorax and pategise slender. Primaries have the black markings 

 of the various horizontal and transverse lines so diminutive that they appear merely as 

 a number of irregular dots and dashes. Secondaries have a marginal transverse row 

 of black dots and a prominent discal dot. A bright rose colored shade along basal 

 margin. Abdomen bright rose, with black dorsal and lateral lines, and black 

 anal tip. 



Habitat: Northern Utah. 

 Types coll. Hy. Edwards and B. Neumcegen. 



This insect is the connecting link between the Kevadensis and docta 

 groups, and shows how near akin they are Mormonica, but for its color 

 and slender markings, resembles A. Anthoka Bd. in its primaries and A. 

 Mexicana Gr. and R. in its secondaries. 



As I stated, at the time, in Papilio Vol. VIII, p. 151, A. incorrupta 

 Hy. Edw., is undoubtedly the typical form and A. Nevadtnsis Gr. and R. 

 but a variety; but entomological etiquette, much to the detriment of clear 

 scientific understanding, giving the first disvoverer the preference, Neva- 

 densis will have to lead the line, which stands, as far as we know, now: 

 A. Nevadensis, Gr. and R. 

 v. incorrupta, Hy. Edw. 

 0. Sulphurica, Neumgn. 

 v. Mormonica, Neumgn. 



A. elongata' Stretch, from Spokane falls, Wash. T. , lately described, 

 seems to be but another local form of this extremely variable insect. 



Arctia v. sulphurica: This is simply a correction for the v. ochracea
