14. Gymnognathus clelia spec. nov. 



?. P_vgidiiiiu and anal ventral segment rounded at apex. IJostriiiii and lit-ad 

 with broad reddish mesial vitta, including a large brown mesial spot on occiput ; 

 mesial carina feebly elevate, but visilile from apex of rostrum to prothorax. 

 Rostrum shorter than in ancora. Frons more than half the width of the rostrum. 

 Prothorax transversely rngulose, with three vittae, which are reddish in front ; one 

 in middle, extending from base to middle of disc or continued as a thin red line 

 to apex, and one on each side, broad, merged together at hinder angle of pro- 

 thorax with the grey ventral area, extending obliquely to apex, being continuous 

 with the lateral vitta of the head ; carina somewhat shorter than in ancora at 

 the sides, angle a little more obtnse. Elytra shorter and more de])ressed than 

 in ancora, more strongly declivous behind, reddish grey area similar, broader, 

 extended proximally to lateral margin, enclosing brown shoulder-angle, posteriorly 

 dilated to seventh strii)e, here nearly touching a rather large marginal median 

 spot, deeply sinuate behind on suture ; apical spot large, reddish, rounded on discal 

 side, the two spots ibrming a transverse band, inclnding between themselves a 

 brown elliptical sutural sj)0t. Pygidium reddish, with extremely thin brown border.

lo. Gymnognathus erna spec. nov. 



? . Allied to irma. Eostrum somewhat shorter : triangular brown mesial 

 patch of occiput continued across pronotnm, gradually and regularly widening 

 posticad, with straight obliijue sides : mesial vitta of pronotum narrower at base 

 than in irma, the brown stripe very slightly narrowing frontad, about as broad at 

 carina as mesial vitta ; upper border of grey sides of pronotum slightly yellowish, 

 indistinctly separated from the ventral area by a slightly thinner pubescent vitta, 

 this yellowish border corresponding to the lateral occipital vitta. Elytra shorter 

 than in irma, the dorsal patch practically the same, being more evenly sinuate 

 laterally, apical spot larger, being rounded on discal side, not emarginate. Pygidium 

 much longer, twice as long as broad, white, rounded at apex. Underside white. 

 Legs rufescent, tarsi and apex of tibiae black.
