Paranthribus gen. nov. 



?. Similar to Anthrcno.wma and Piezocori/uun. Rostrum and eye similar to 

 those oi A/it/ire/wsoma. Antenna reaching base of elytra, with single long hairs, 

 segments 1 and 2 incrassate, 3 to 7 thin, 3 = 4, longer than 2, 8 nearly three times 

 as long as broad, a little broader than 7, club loose, 9= 10, shorter than H, 

 9 asymmetrical, widest just beyond middle, 10 with rounded sides, 11 elliptical. 

 Prothorax more than twice as broad as long ; carina basal, less angnlate than in 

 Antkrenosoma, the basal margin of the elytrum being less curved, flexed forward 

 at sides beyond middle, this lateral carina as distinct as the dorsal one, side of 

 prothorax emarginate Ijefore base, then rounded, apical edge not in the least 

 projecting ; lateral angle of carina 00', but tip rounded. Prosteruum longer than 

 in Anthrenogoma, forecoxae nearly contiguous.

8.3. Paranthribus rufescens spec. nov. 



? . Rufescent, head and pronotum more brown, pubescence greyish clay, 

 pronotum almost regularly dotted ; elytra irregularly tesselate 1, the rufescent 

 brown spots long in third interspace. Antenna rufous at base, segments in and 1 1 

 luteous. Legs rufous, basal two-thirds of femora, apex of tibiae and second tarsal 

 segment more or less brown. Rostrum four times as broad as long, emargiijate 

 in middle of apical edge. F'rons more than half the width of the rostrum. Pro- 

 notum convex ; slightly depressed before carina, rugnlose, apical margin rufescent 

 Elytra subcylindrical, as wide as prothorax at base, a little rounded-widened before 

 middle, then gradually narrowed ; apex truncate-emargiuate, with the lateral angle 

 rounded oft'; deeply punctate-striate, interspaces iinely grannlose, convex ; the third 

 a little more elevate than the others. Underside somewhat irrorated with brown 

 jiubescence, as are the legs.
