S ? . Pygidinm ami anal sternite rounded, the former with a large mesial 

 coral-red spot. Black-lirown, ]{ostrnm dilated at apex, nearly twice as long as 

 broad in middle, rngato-pliuate, with thin basal carina which flattens in middle 

 and disappears before reaching apical margin ; white. Frons plicate, pubescent 

 coral-red in middle, white at eyes. Antenna black-brown, segments 1 and 2 

 rufescent, 3 longer than 4, 7 half as long again as S, this nearly two (?) or three (c?) 

 times as long as broad. Prothorax densely rugate ; a coral-red apical marginal patch 

 behind eye ; a mesial vitta, constricted before middle, widened at carina, followed 

 by a basal mesial patch, a short discal line, slightly arched, convex externally, 

 midway between ajiex and carina, a lateral basal spot exteuded discad beyond 

 carina, not reaching short discal line, dilated along lateral carina, contiguous with 

 an ill-defined oblique band which extends from red spot downwards to base of 

 prnsternum : lateral angle of carina 90°, but rounded off ; basal longitudinal 

 carina at a right angle with dorsal carina ; lateral carina not reaching middle. 

 Elytra flattened, not impressed, slightly convex at base, lines of punctures very 

 distinct, interspaces 2, 4, 6, 8 and part of 10 white ; an oblique band from outer 

 side of shoulder to fourth interspace, a transverse subapical band across both elytra, 

 slightly curved forward at suture, and lateral interspaces brown, excepting ninth, 

 which is cinnamon from middle to declivous apex, like rest of elytra. Pygidium 

 coral-red, rather broadly edged with white. A vitta on presternum, from coxa 

 obliquely forward, sides of meso-metasternum, except a brown median spot, and 

 four contiguous spots on abdominal segments 2 to .i, creamy-white ; rest of 

 underside and legs black, sparsely pubescent white ; knees rufescent.

0. Gymnognathus bella spec. nov. 



? . Pygidium and anal sternite emargiuate-truncate, angles rounded, the 

 former red, with thin grey edges. Rostrum strongly dilated at apex, twice as 

 long as broad in middle, with strong mesial carina, which does not quite reach apical 

 margin, coutiuued to occiput ; pubescence reddish, a transverse basal belt grey. 

 Frons multii)licate, coral-red like occiput, eye thinly edged with yellow-buff, a 

 patch behind eye and a streak below yellow-buff. Antenna brown-black, club 

 olivescent, segment 3 little longer than 4, 7 and 8 broader than long, club very 

 broad. Prothorax half as broad again as long, cmarginate at apex, black, a 

 dorso-lateral apical patch coral-red, seven grey dorsal vittae, mesial one from 

 apex to carina, followed by a basal patch, first lateral neither reaching apex nor 

 carina, subangnlate in middle, second from carina to middle, ending here in a dot, 

 third somewhat irregular, from near carina to red sjiot, continued along the outer 

 edge of this spot ; moreover, a broad lateral vitta divided by the lateral carina ; 

 carina concave in middle, flexed forward at side in an even arch ; basal longitudinal 

 carina forming an acute angle with dorsal one. Elytra pubescent cinnamon, all 

 the stripes of punctures white, here and there interrupted, alternate interspaces
