 And drift by the peaks of perpetual snow.

Imago (53:1). Head moderately large, rather densely clothed with long and 

 slunt erect hairs. Front very moderately swollen, scarcely fuller beneath, as broad as 

 iiigh, scarcely as broad as the eyes; upper edge rather broadly rounded and protuber- 

 ant in the middle, wliere it falls rather abruptly, and nearly as much as at the sides; 

 lower edge well rounded. Vertex rather small, partly tumid, but posteriorly pro- 

 jecting beyond the height of the eyes only a very little, broadly rounded behind, in 

 front "advancing with curved sides deeply and sharply into the space between the 

 antennae, Avhere it is greatly sunken and connected with the front by a narrow bridge. 

 Eyes not very large, pretty full, sparsely pilose with long hairs, longest in front in 

 the middle of the upper half. Antennae inserted deeply in the middle of the summit 

 in nearly connected pits, their interior bases separated by the width of the antennal 

 st:ilk. and on their exterior bases closely crowded to the margin of the eyes; nearly 

 half as long again as the abdomen, consisting of from thirty-live to thirty-six joints, 

 the last nine or ten of which expand gradually into an oblong-ovate, depressed club, 

 about four times as broad as the stalk, four times as long as broad, the extremity 

 broadly rounded, three joints entering into the diminution of size, but the last disturb- 

 ing the uniformity by being very bluntly conical, depressed; club furnished along tlie 

 under portion of the inner side with a slight triple carina, which continues indistiiictly 

 along the greater portion of the stalk. Palpi stout, scarcely three times as long as the 

 eye, 'compressed, curved slightly, the terminal joint one-third the length of the penul- 

 timate, the whole furnished with fine longer, and coarse shorter hairs, most conspicuous 

 on the penultimate joint, and restricted generally, and especially above, to a vertical 

 plane, adding to its compressed appearance.
