Genus Neominois 



the body cylindrical, gradually tapering backward, and provided 

 with two very short conical anal horns. 



Chrysal/s.—Tbe chrysalis is formed under the surface of the 

 earth; it is rounded, somewhat carinate, or keel-shaped, where 

 the wing-cases unite on the ventral side. The head is rounded, 

 the thorax strongly arched, the dorsal side of the abdomen very 

 convex. On either side of the head are small clusters of fine 

 processes shaped somewhat like an Indian club, the thickened 

 part studded with little spur-like projections. These can only 

 be seen under the microscope. 



But two species of the genus are known within our faunal 

 limits. 



(i) Neominois ridingsi, Edwards, Plate XXV, Fig. 15, S 

 (Ridings' Satyr). 



Butterfly.— The upper side is well depicted in the plate. 

 The under side is paler than the upper side, and the basal and me- 

 dian areas of both wings are profusely mottled with narrow pale- 

 brown striae, the secondaries crossed by a darker mesial band, the 

 outer margin of which is sharply indented. Expanse, 1.50 inch. 

 Early Stages.— 1\\qsq have been beautifully ascertained, de- 

 scribed, and figured by Edwards in the third volume of " The 

 Butterflies of North America." The egg, larva, and chrysalis 

 agree with the generic description already given, which is based 

 upon the researches of Edwards. 



It is found in the Moiintain States of the Pacific coast. 

 (2) Neominois dionysius, Scudder, Plate XXV, Fig. 16, $ 

 (Scudder's Satyr). 



5// //tryZ;'. — Distinguished from the preceding species by the 

 larger and paler submarginal markings on the upper side of the 

 wings and the pale color of the basal tract in both wings. On 

 the under side the median band of the secondaries is narrower 

 and more irregularly curved than in ridingsi, with the dentations 

 of the outer margin more sharply produced. Expanse, 1.90 inch. 

 Early S/j^^5.— Nothing has been written on the early stages, 

 but no doubt they agree closely with those of the other species. 

 It is found in Utah, Colorado, and Arizona.
