COLEOFTEEA.—LEA. 193 



sharply seveii-areolate, apex produced in middle and truncated, sides strongly 

 elevated, angularly narrowed to middle ; front angles rounded off, hind ones 

 produced and acute. Elytra almost parallel-sided; with regular double rows of 

 punctures, the alternate interstices elevated. Hind tihim somewhat thickened 

 in middle, lower edge bisinuate, apex thickened and notched. Length ' {$ 9), 

 10-12 mm. 



$ Differs in having shorter and less strongly serrated antennae, hind 

 tibite not so wide, the apex not thickened, and abdomen not notched.

There are many other species of the allied genera having the prothorax 

 and apex of elytra black, but this is the only known one in which the rostrum is 

 long, it5 length being about two-thirds that of the prothorax ; in my table it 

 would be placed watli M. disconiger, but the black of the elytra is confined to the 

 apex. The hind tibiae of the male are dilated to the apex as viewed from behind, 

 but they seem to be narrowed there from some directions. 



METRIORRHYxNCHUS CRYPTOLEUCUS sp. nov. 

 (J Black, elytra and sides of prothorax brick-red. 



Head Avith rostrum rather long and moderatelj^ wide. Antennae rather 

 long, strongly serrated, third joint stouter and slightly longer than fourth, 

 eleventh conspicuously longer than tenth. Prothorax moderately transverse, 

 distinctly seven-areolate, front somewhat rounded in middle, front angles widely 

 rounded off, sides feebly increasing in width and height to base, but hind angles 

 projecting outwards. Elytra almost parallel-sided ; with regular double rows 

 of transversel}' oblong punctures, the odd interstices regularly elevated. 

 Subapical segment of abdomen with a wide median notch almost to base. Hind 

 tihm somewhat thickened. Length ( (J 9 ) , 14-20 mm. 



9 Differs in having antenna? shorter and less strongly serrated, subapical 

 segment of abdomen not notched, the apical one with a slight median notch at 

 apex, on each side of which is a small elevation, and hind tibias thinner.

A rather large species, in some respects close to M. variipcnnis, and elytra 

 sometimes partly dark (on twelve specimens entirely pale), but rostrum somewhat 

 shorter, and sides of prothorax not angularly dilated near base; from above the 

 margins of the prothorax appear to be gently and evenly (except for a feeble 

 sinuation) dilated to the base, from the sides they appear to be gently and evenly 

 convex ; but on that species the margins, from all points of view, are seen to be 

 suddenly and angularly dilated near the base. On most of the specimens the
