PLATE I, FIGS. 1-7. 



Head (fig. 1) broader than long, sides convex, posterior margin concave, 

 slightly depressed along the median line. 



Eyes large, lateral, remote from each other, black. 



Antennae covered with minute, cylindrical papillae, which are a little swollen 

 and lobed at the end ; median, cylindrical for inner two-thirds, outer third con- 

 ical, delicate ; basal article large, swollen ; in length falling a little short of the 

 palpi ; lateral, about one-half as long as the median, fusiform ; basal articles 

 cylindrical, a little longer than that of the median antenna. 



Palpi smooth, very changeable in form, at rest a little longer than the median 

 antenna, tapering uniformly to near the end, where the diameter suddenly 

 diminishes. 



Tentacular cirri with cylindrical basal articles ; superior about the length of 

 median antenna ; inferior but little shorter than superior ; these cirri, together 

 with the dorsal and anal cirri, have the same structure, in all respects, as the 

 median antenna, but the dorsal cirri are a trifle longer than the superior tentac- 

 ular cirri, and the anal are a little longer than the dorsal. 



Elytra, first pair (fig. 5) nearly circular; the rest (fig. 6) reniform ; covering 

 the body completely in front, but further back not quite touching along the 

 middle line, leaving a narrow, naked, median space ; when magnified, seen to 

 be covered with minute granules, around each of which is a circular depression ;
