Behold again, with saffron wing superb. 

 The giddy buttcrtly. Keleased at length 

 From his warm winter cell, be mounts on high, 

 No longer reiilile, Init endowed with iilumes. 

 And through tbe blue air wanders; pert, alights, 

 And seems to sleep, but from tbe treacherous hand 

 Snatches his beauties suddenly away 

 And zigzag dances o'er the flowery dell. 



HURDIS. 



Imago (56: 1). Head rather larpre, covered with rather short, very close hairs, 

 having; a tendency to form transverse tufts. Front depressed above, tumid on the 

 sides and beneath, projecting considerably beyond the front of the eyes; on the upper 

 half is a slender, longitudinal, median ridge, rather briefly bifld at tlie upper extremity 

 next the hinder edge of the antennae, expanding considerably at the lower extremity ; 

 the fullness of the sides is limited by a distinct, rather abrupt, semicircular ridge, 

 hollowed broadly in front of each antenna; as broad as high, nearly as broad as the 

 eye on a front view, the sides scarcely diverging upward ; upper border extending rattier 

 narrowly between the antennal pits, and following their curve; edge of pits a little 

 rounded; lower border raised a little in the middle, very broadly rounded, almost 

 straight. Vertex rather depressed, a little and broadly tumid along the middle, the 

 upper outer corners produced a little forward and gibbous ; anterior border, excepting 

 the corners, straight, falling abruptly so as to form a slightly elevated ridge. Eyes 

 angulated next the front border of the antennae, large, full, naked. Antennae in- 

 serted in the middle of the summit in distinct, deep pits, open toward the eyes, sepa- 

 rated from eacli other by a space half as bro-ad as the antennal pits; of the length of 

 the abdomen, composed of forty-three joints, of which the last ten or eleven form the 

 scarcely depressed cylindrical club, which increases so gradually and little in tliickncss 

 that it is dilllcult to determine its limits ; it increases slightly in size to the very last. 

 the terminal joint as large as the preceding. t)eing very broadly rounded, almost 

 abruptly docked ; club less than twice as broad as the stalk and six or seven times 

 longer than broad ; each joint has, next the base, on tlie inner lower surface, a rather 

 large, shallow, oval depression. Palpi short and very stout, compressed, half as long 

 again as the eye, the last joint very minute, the middle about two-flfths the length of 

 the basal joint, which here composes, in place of the middle joint, the bulk of the 

 member, all furnished with a heavy broad mass of closely clustered scales, greatly 

 compressed in a vertical plane, tlie upper surface of the middle joint l)roadest. 



Prothoracic lobes directed upward and a little inward, the upper surface broadly 

 and regularly rounded, the inner upper angle well rounded, a little produced, below 

 tapering greatly ; moderately tumid, but viewed from above strongly appressed, lenti- 

 cular, the edge uppermost. Patagia rather large, long and slender, scarcely arched, 

 a very little tumid, the oater margin slightly thickened, nearly four times longer than
