Staj" thy soft-inurinuring waters, gentle Rill ; 

 Hush, whis|)(M-ing AViiids; ye rustling Leaves he still; 

 Rest, silver Butterllies, your quivering wings; 

 Alight, ye Beetles, from your airy rings; 

 Ye painted Moths, your gold-eyed plumage furl. 

 Bow your wide horns, your spiral trunks uncurl; 

 Glitte'r, ye Glow-worms, on your mossy beds; 

 Descend, ye Spiders, on your lengthened threads; 

 Slide here, ye horned Snails, with varnish'd shells; 

 Yc Bee-nymphs, listen in your waxen cells!

Imago (53: 2). Head prettj^ large, furni-slied with abundant, longer and shorter 

 hairs, longest around the antennae. Front pretty full, in the middle below consider- 

 ably i)rotuberant, above broadly and slightly depressed, in the middle slightly and 

 rather broadly hollowed longitudinally; the middle of the upper border thrust back- 

 ward considerably between the antennae, the sides of the projection curving around 

 the antennal bases ; broader than high, but not so broad as the eyes. Vertex rathei' 

 large, rather tumid but scarcely elevated above the upper level of the eyes, more than 

 twice as broad as long, the hinder border broadly rounded, scarcely appressed, the 

 front border abruptly descending, projecting angulai'ly in the middle, the sides of the 

 angulation scarcely rounded. Eyes pretty large, full, naked. Antennae inserted 

 slightly in advance of the middle of the summit in pits, the walls of which are 

 higher behind than in front, connected by a rather broad, deep, transverse furrow 

 separated by a space equal to more than the diameter of the summit of the second 

 antennal joint; considerably longer than the abdomen, composed of from forty-one to 

 forty-nine joints, of which from eleven to thirteen form the greatly depressed club, 

 of which the first four and the last five bear the increase and diminution of size, the 

 central joints being about equal ; the club is ovate, five or six times as broad as the 

 stalk, a little more than twice as long as broad, the extremity well rounded, sometimes 

 slightly tapering, the last joint with a minutely produced, couical tip ; furnished in the 

 middle beneath with a distinct median and a pair of indistinct, submedian carinae, 

 the former extending down the stalk. Palpi pretty long, nearly or quite twice as long 

 as the eyes, not stout, curving slightly forward, the apical joint about one-seventh the 

 length of the penultimate; clothed beneath, excepting the apical joint, with long, 

 equal, curving hairs, all in a vertical plane; above, in the middle of the apical 

 half of the second joint, with a long, vertical tuft of hairs which embrace the eyes 

 and then diminish in length to the apex, changing their direction at the same time 

 forwards. 



Prothoracic lobes pretty large, appressed considerably, but somewhat tumid, larger 

 interiorly than exteriorly, well rounded at either end, the summit well rounded in 

 either direction, about five times as broad as long and twice as high as long. Patagia 

 long and slender, two anil a ((uarter times as long as broad, the base rather broad, 

 squarish, the posterior lobe at first continuing in the line of the outer margin and 

 narrowing rapidly, afterward of nearly uniform width and bent considerably down- 

 ward in continuation of the inner margin, the tip bluntly rounded. 



Fore wings (39: 6) more that two-thirds as long again as broad, the costal border 

 pretty strongly and quite regularly boAved, the apical angle well rounded ; outer margin, 

 excepting the well rounded angles, straight or scarcely convex; inner margin straight 

 or scarcely sinuous, at about 100^ Avith the outer border. First superior subcostal 

 nervule arising a little beyond the middle of the outer half of the cell; the second 

 half way or somewhat more than half way from that to the apex of the cell, or shortly
