There through the long, long summer hours, 



The golden light should "lie. 

 And thick youna: herbs and groups of flowers 



Stand in their beauty by. 

 The oriole .should build and tell 

 His love tale close beside mv cell; 



The idle butterfly 

 Should rest him there, and there be heard 

 The housewife bee and humming-bird.

Imago (58 : 1). Head (61 : 14) very large, clothed with short, equal hairs arranged 

 to a considerable extent in transverse, scarcely appressed ridges, and with a slender, 

 tapering, slightly curving pencil of stiff hairs, from the outer base of the antennae 

 projecting over the eyes and about one-fourth their semi-circumference in length. 

 The whole of the front projecting a little and equally beyond the front of the eyes, a 

 little more full across the middle than elsewhere, but not forming a transverse ridge; 

 the margin of the sides is rounded, and scarcely reaches the middle of the front of 

 the antennal bases, the front and hiud border straight, and the former longer than the 

 latter ; it is nearly or quite twice as broad as long. Vertex almost flat, nowhere reach- 

 ing the level of the eyes, about as long as the front, meeting it by an impressed, 

 straight sulcation, connecting the middle of the antennal bases, and separated from the 

 occiput by a slightly impressed, slightly arcuate line, obsolete laterally, its concavity 

 for(vard. Eyes large, full, more broadly rounded behind than in front, naked. Anten- 

 nae inserted with their hinder edge scarcely behind the middle of the summit in slight 

 pits, their interior bases separated from each other by nearly twice the diameter of the 

 base of the .antennae; exclusive of the crook, one-fourth longer than the abdomen, 

 composed of thirty-seven joints, of which the last thirty form the club, which is a 

 little less than half as long as the very slender stalk, and bent a little beyond the 

 mitkile, at aljout the forty-second joint ; the basal half or a little more than that of 

 the straight i)ortion of the club is regularly incrassated, so as to be thickest at about 

 the thirty-fourth joint, and there scarcely equals in thickness the length of three 

 consecutive joints, then tapers again very slightly, the crook continuing the regular 

 diminution Insize, and ending in a bluntly pointed tip, the whole club subcylindrical ; the 

 longest joints of the stalk are four times as long as broad, and the crook Is generally 

 recurved at a little less than a right angle. Palpi very short and exceedingly stout, 

 yet not nearly so stout as in Eudamus, a little longer than the eye, heavily clothed with 

 long and erect scales, beyond which the apical joint, clothed only with recumbent 

 scales, scarcely projects ; the basal joint is globose, the anterior part of its tip greatly 

 produced anteriorly and upwards, so as almost to embrace the base of the middle 

 joint ; the middle joint ovate, regular, two and one-half times longer than broad, and
