NO. 7 THE GOLD-BANDED SKIPPER CLARK 33 



slender, and pointed transparent hairs that become somewhat more 

 numerous on the lower lateral borders of the segments, and much more 

 numerous and darker on the dorsal surface of the last segment. The 

 prolegs bear numerous down-curved hairs about the foot, and many on 

 the basal portion. 



The ventral surface has rather numerous scattered hairs. 



The anal fan (pi. 8, fig. 52) is long wedge-shaped, ventrally gently 

 convex, with 18 long, tapering, blunt teeth about the rounded distal 

 edge. From the base of each of these teeth a rounded ridge runs to 

 the narrow base. 



The head in this stage resembles very closely the head of Epargyreus 

 tityrus, differing chiefly in its smaller size, in the longer and more 

 numerous hairs with which it is clothed, in its darker color, and in 

 its yellow instead of orange spots. 



The head is claret brown with a large deep chrome spot between 

 the frontal triangle and the ocelli on either side. The border of the 

 chrome-yellow spot adjoining the ocelli is gently concave, following the 

 curved line along which the ocelli are placed, the inner border is 

 evenly rounded, and the upper and lower borders are flattened. The 

 mandibles and antennae are shining black. 



The first thoracic segment bears a smooth clay-colored dorsal shield 

 narrowly bordered in the middle third of the anterior margin with 

 olive buff. A fine line of olive buff runs across it in the middorsal line 

 of the caterpillar. A narrow groove near the posterior margin of the 

 shield running not quite to the ends on either side is darker in color 

 than the rest of the shield. The remainder of the first thoracic seg- 

 ment is bright rose red, or rose red below and straw yellow above, the 

 two colors being divided by a line running from the lower portion of 

 the sides of the neck just behind the head backward and upward to a 

 point on the second thoracic segment at the level of the end of the 

 thoracic shield. 



The dorsal portion of the body is apple green with numerous evenly 

 distributed small sulphur-yellow dots which are darkest in the anterior 

 third, gradually becoming paler posteriorly. 



The dorsal surface is delimited by a conspicuous broad lateral line 

 of clear sulphur yellow. In the middle of the body this line is some- 

 what wider than the height of the deep chrome spots on the head, but 

 it tapers to less than half this width at either end. The line is in 

 reality interrupted, being composed on each segment of an irregularly 

 bounded, but more or less squarish, mark followed by a broad vertical 

 dash of the same height or slightly higher, which in turn is followed 

 by three narrower vertical lines of the same length or slightly longer.
