Yet once I li\ed not needing love. I : no. 

 Oh, 'twas but I as the worm that crawls and feeds 

 Is the winged rapture drunken with free air 

 That's playmate to the sunlieams. Oh, this love I 

 Stellio, thou hast given me a soul.

Imago (60 : 4). Head large, clothed with transverse masses of rather short hairs ; 

 just outside the antennae a short, spreading, appressed bunch of arcuate bristles, pas- 

 sing about one-tifth way around the eye. Front tumid, very protuberant, the whole 

 extending some distance beyond the front of the eyes, increasingly protuberant from 

 above downward : transversely, pretty strongly arcuate, flattened in the middle, hollowed 

 for some distance next the antennae ; about three times as broad as long, subquadrate, 

 the anterior outer angles rounded ofl' and the middle of the front border delicately 

 marginate and slightly excised ; separated from the vertex by a scarcely impressed, 

 straight line connecting the middle of the antennae. Vertex scarcely tumid, just about 

 level with the surface of the eyes, transversely flat or scarcely arcuate; separated 

 from the occiput which is rather deeply sulcate in the middle longitudinally, by a 

 slightly impressed, brace-shaped line. Eyes large, moderately full, nearly circular, 

 but slightly docked posteriorly, naked. Antennae situated with the hinder edge in 

 the middle of the summit, separated from each other by scarcely more than two and a 

 half times the diameter of the basal joints, the whole antenna a little longer th.an the 

 abdomen, composed of forty-one joints ( § not examined), of which twenty-three form 

 the club which is fully half as long as the stalk; the crook excluded, it is more than 

 four times as long as broad, rather slender, cylindrico-oval, largest in the middle and 

 tapering very gradually toward the base, more rapidly toward the tip where it is 

 rounded ofl" and bears the very long and slender, delicately tapering and pointed crook, 

 which is composed of nine joints and is four or live times as long as broad'and half 

 as long again as the breadth of the club; middle joints of the stalk three times, the 

 third from base of antennae four times as long as broad. Palpi pretty stout, about 

 one and a half times longer than the diameter of the eye, covered profusely with long 

 scales, a little appressed in front on the apical half of the palpi, beyond which nearly 

 the whole of the small apical joint protrudes; basal joint buUate, subpyriform,
