whether bilobed or undivided, smooth and flabby, or showing the great conical papillae, des- 

 cribed by Gravier and Mc Intosh ; the remaining part of the elytron is covered with small 

 papillae, having a globular base and one to four chitinous spikes. The two pairs of eyes are 

 nearly equal in size and there is a distinct nuchal collar, with two lateral papillae. The para- 

 podia of the 2"^ segment have a long ventral cirrus and bear a fascicle of ventral setae, diffe- 

 ring from these of the remaining body, as first noted by Gravier. The real structure of the 

 ordinary ventral bristles (PI. XV, fig. S) is not easily to understand and I presume, that it 

 escaped Grube as well as Mc Intosh ; for these setae have a nearly triangular transverse section 

 and like a sword have a sharp edge (the concave side), whereas the dorsal margin (the convex 

 side) is broadened. Their subterminal dilatation bears on both lateral sides the iisiial transverse 

 fringes, that however do not lay in the same line at the right and left side, but are alternatincr 

 with each other. These fringes are laciniate and their teeth increase in size distally, whereas those 

 situated next to the sharp edge are the largest ; the two distal fringes usually have only a 

 -single tooth. In the specimens of the Red Sea, described by Gravier, these large teeth appear 

 to be entirely wanting (fig. 218). Po/ynoc tiunorifei'a Gr.^) from Borneo presumably will 

 prove to be identical with Lcpid. cristafus Gr.

In the specimens of Stat. 144 and 154 the chitinous patches of the elytra are rust- 

 coloured. Those of Stat. 96 and of Pulu-Weh have a carmine colour and a dark spot, sur- 

 rounded by a paler ring on the midst of the elytra ; the bilobed crest is faintly developed and 

 consists only of a couple of slight elevations, provided with a pair of white tubercles. The 

 papillae upon the remaining surface of the elytron have a particular shape and are beset with 

 4 or 5 blunt tubercles. In variance with Mr. Potts I ob.served a conspicuous spur beneath 

 the apex of nearly all ventral setae.
