SATYRODES I. 



itself is surrounded hy a dark ring and a pale halo, and each has a white pupil ; 

 the anal spot duplex, with double pupil. 



Body above color of wings, beneath, the thorax and abdomen yellow-white, or 

 in the darkest winged examples, brown-yellow ; legs yellow-brown above, whitish 

 below ; palpi yellow-white with brown hairs in front ; antennae fuscous above, 

 narrowly ringed yellow or whitish, beneath red-brown ; club fuscous, the top 

 red-brown. (Figs. 1, 2, var. 5.) 



Female. — Expands from 1.7 to 2.4 inches. 



In general like the male, but of paler hue ; the spots larger ; on the under 

 side the inner rings are more yellow, and each series of spots is inclosed by a 

 pale elongated ring ; but the uppermost spot on secondaries is separated from the 

 rest and has its own set of rings. (Figs. 3, 4.) Examples from Colorado are 

 larger than any from New England, and somewhat larger than from Michigan 

 or Illinois. There is everywhere great variation in the color and markings of 

 this species, but I have never seen an example, nor is there one recorded, that is 

 without the rounded spots on upper side. 



Egg. — Subglobular, much flattened at base, as broad there as high ; surface 

 slightly rough, but without definite markings even under a pretty high power; 

 but increasing this, there are to be seen small shallow cells, and a resemblance to 

 eggs of the Neonymphte ; color greenish-white. (Fig. «). Duration of this stage 

 about seven days. 



Young Larva. — Length .09 inch ; cylindrical ; segment 2 rounded and some- 

 what prominent ; fi'om .3 to 11 tapering very gradually, 12 and 13 abruptly, and 

 ending in two short pointed tails ; color at first yellow-white, in a few hours 

 changing to pale green ; the upper surface shows six longitudinal rows of low, 

 conical, black tubercles, each of which gives a short, thick, black bristle, thick- 

 ened at the end ; on 3 and 4 these are in cross line, on middle of the segment ; 

 on 2, the tubercles of the upper rows are advanced to front, and behind and be- 

 tween is an additional tubercle ; that of the lateral row is above the line and in 

 middle of the segment, and is without bristle, and below, in front of the spiracle, 

 is a smaller tubercle and hair, and under it a hair without tubercle ; on 4 to 12 the 

 tubercles are in triangle, as in Neonymphfe ; on 13 is a triangle at the front, two 

 at base of tail corresponding to the upper rows, and longer than elsewhere ; at 

 the end of the tail a still longer bristle ; along the base of the body is a row of 

 short hairs, two on 2 and from 4 to 12, one on 3, 4, springing from tubercles and 

 longer and tapering, one on 13 ; still another row of very short, tapering hairs
