BUTTERFLIES OP MONTANA. 157 



Fig. 116. Ochloedes sassacus, upper and lower surfaces of male. 



Female This is larger, the fulvous ground color paler, the outer mar- 

 ginal shades darker, and the discal stigma is replaced by a dark brown 

 shade. The fore wings have a row of eight yellow spots, and two elongate 

 spots, more or less distinct, in the outer part of the cell. 



On the under side the spots of the fore wings are repeated, pale, the 

 lower of the outer row broadly expanded. 



Body brown above, with grayish hairs, lighter beneath. 



Early Stages The caterpillar feeds on grasses. 



Distribution From New England to Florida, westward to Colorado 

 and Montana. In Montana collected by Elrod at Missoula (9), at Mc- 

 Donald Lake in the Mission Mountains (3), and in numbers of the Uni- 

 versity of Montana iological Station. Douglas and Smith collected it at 

 Wiles Hot Springs (14). 



Genus LIMOCH ROES. Scudder. 



The antennae are about half as long as the costa; the club is robust, 

 elongate, with a very short terminal crook; the palpi have the third joint 

 erect, short, bluntly conical. The male has a linear discal stigma on the 

 upper side of the fore wing. The egg is hemispherical, somewhat flat- 

 tened on the top. The larvae feed on grasses, and construct a tube-like 

 nest of delicate films of silk between the blades. 



THE CROSS-LINE SKIPPER, Limochroes manataaqua, Scudder. 



Butterfly Expanse, 1.00 to 1.20 inches, 25 to 33 mm. 



In the male the wings are dark brown marked and tinged with yellow; 

 the brand is very slender and nearly straight; outside of it there is a 

 patch of brown scales, which makes it appear wider than it is; between 

 the brand and the costal margin the wing is heavily covered with yellow 

 scales, and the transverse row of spots beyond the middle of the wing is 

 more or less distinct; the hind wings are tinged with yellow, sometimess 

 the transverse row of spots is faintly indicated. 



In the female the wings are dark brown above with a transverse row 

 of whitish spots beyond the middle of the fore wing; hind wings without 

 spots. 



Distribution The species is reported to have a general distribution 

 over the United States. It has been collected by Cooley at Bozeman.
