144 Pliytophaga Malar/ana. 



above the apex of the epistome coarsely punctured ; epistome 

 scarcely longer than broad, sides nearly straight and parallel, 

 rounded and converging towards the apex ; apical border broadly 

 obsolete, anterior margin concave ; surface coarsely punctured ; 

 antennae scarcely more than half the length of the body, very 

 slightly thickened externally, black, the five lower joints, together 

 with the labrum and the anterior border of the epistome, ob- 

 scure fulvous. Thorax twice and a half as broad as long, 

 sides rounded, converging in front; above transversely convex, 

 deeply but not very coarsely punctured. Elytra broadly exca- 

 vated along the outer border, just within the lateral margin ; 

 deeply and more coarsely punctured than the thorax, the punc- 

 tures irregularly arranged in numerous longitudinal rows, which 

 on the hinder disk become less in number, and here and there 

 approximate in pairs, the interspaces being slightly thickened and 

 convex. Thighs simple.

Late ovata, convexa, subtus nigra, pectore pedibusque caeruleis, 

 supra viridi-senea, nitida ; labro antennisque obscure-fulvis, 

 bis extrorsum nigris ; elytris anguste caeruleo-limbatis, sub- 

 striatim punctatis, interspatiis disci exterioris leviter incras-

Head distantly punctured ; epistome triangular, apical border 

 obsolete, anterior margin broadly concave-emarginate ; surface 

 coarsely and somewhat closely punctured ; the lower portion of 

 the front, together with the apex of the epistome, broadly de- 

 pressed, supra-ocular grooves nearly obsolete; encarpae slightly 

 thickened; antennae subfiliform, five lower joints obscure-ful- 

 vous. Thorax twice as broad as long, sides straight and parallel 

 from the base to the middle, tlience obliquely rounded and con- 

 verging to the apex ; above convex, sides distinctly deflexed in 

 front, narrowly edged with metallic-blue ; surface distinctly but 

 not very closely punctured. Elytra not depressed below the 

 basilar space, distinctly punctured, the punctures irregularly placed 

 in double rows, which on the hinder disk become single and more 

 regular; the punctures on the outer disk in front are larger and 

 more deeply impressed ; interspaces smooth, on the anterior portion 

 of the outer disk they are thickened, and form obsoletely transverse
