I saw him run after 

 a gilded butterfly ; and when he cauirht it, he let it 

 go again ; and after it again ; and over and over he 

 comes, and up ajjaia; catched it .again: or whether 

 X his fall enraged him, or how 'twas, he did so set his 



teeth, and tear it; O, I warrant, how he mam- 

 mocked it !

Imago (59:1). Head large, heavily clothed with moderately long hairs arranged 

 obscurely iu transverse masses: outside of the antennae a slightly spreading, appressed 

 bunch of arcuate bristles, the lowest the longest, but not extending over more than 

 one-fourth the contour of the eye. Front protuberant and bnllate, ridged transversely 

 below the middle throughout nearly the entire breadth, and so as to surpass greatly 

 the front of the eyes ; above the ridge it is slightly tumid ; below the ridge, the slope 

 is a little ridged again across the middle ; the whole piece is much more than twice as 

 broad as long, its inferior margin broadly and regularly rounded, reaching to the outer 

 front edge of the antennae, separated from the vertex by a transverse, very slightly 

 arcuate, shallow sulcation, its convexity forward, terminating on either side at the 

 middle of the antennae. Vertex slightly tumid longitudinally, scarcely tumid trans- 

 versely, barely surpassing the eyes on the anterior, barely surpassed by the eyes on 

 the posterior half, of the same length as the front, separated from the occiput by a 

 slightly impressed, brace-shaped line; the latter deeply sulcated in the middle longi- 

 tudinally. Eyes large, full, fullest in advance of the middle, nearly circular, naked. 

 Antennae inserted with their hinder edges in the middle of the space included 

 between the transverse ridge of the front and the back of the head, their inte- 

 rior edges separated by fully three times the diameter of the basal joints, the whole 

 antenna plainly shorter than the abdomen, composed of thirty-two joints, of which 

 sixteen form the club, which is less than one-third the length of the stalk, the crook 

 consisting of but a single, minute, conical joint, half as long again as bro.ad and 

 less than one-third the length of the middle joints of the stalk; the club is stout 

 oval, much more arched above than below, fully three times as long as broad, 

 largest from the fifth to the eleventh joints, but increasing gr.adn,ally in size from the 

 base, and abruptly and broadly rounded at the tip. Middle joints of the stalk a little 

 more than twice as long as broad, the third joint fully six times as long as broad. 

 Palpi pretty short and very stout, the length not more than one and one-half times the 

 diameter of the eye, clothed very compactly with a mass of long scales, beyond which 

 the slender apical joint, clothed only with recumbent scales, projects rather con- 

 spicuously; basal joint small, bulbous, subpyriform, about as long as broad; middle 

 joint very tumid, ovate, broadly and equally rounded at either extremity, nearly or 

 quite straight, broader than the basal joint and nearly twice as long as broad; apical
