neio genera and species of CryptocephaUda. 219 



distinctly punctured, the punctures piceous, arranged in 

 double rows at the base and along the suture; the second 

 black spot on the elyti-on (when present) is rotundate and 

 placed below the middle, half-way between the suture and 

 outer margin, the spot on the humeral callus is oblong ; 

 the inflexed limb is stained behind the middle Avitli nigro- 

 piceous. Apical segment of abdomen in the $ impressed 

 with a large shallow fovea, the anterior edge of which is 

 armed with a flattened tooth ; the same segment in the $ 

 is impressed with the usual deep fovea. 



In colour this species closely agrees with C. Japanus. 

 It is much smaller, and in its typical form lias only two 

 instead of four black spots on each elytron.

Elongato-ovatus, convexus, obscure fulvus, nitidus, 

 capite flavo, antennis (basi fu'lva excepta) oculisque nigris ; 

 pectore abdomineque (hujus apice excepto) pallide piceis ; 

 scutello elytrisque violaceo-piceis ; thorace Ifevi, margine 

 antico lateribusque flavis ; elytris sat fortiter punctato- 

 striatis, interspatiis planis, duobus externis convexis; 

 utroque el}i;ro \atta interru]5ta, pone medium abbreviata,

Head smooth ; eyes elongate, not contiguous, broadly 

 sinuate, black; antennae scarcely more than half the 

 length of the body in the $ , slightly shorter in the ? ; 

 slender, five lower joints flavous, the six outer ones very 

 glightly thickened, black. 1'horax about a third broader 

 than long at the base ; sides rounded and converging from 

 base to apex, more quickly converging near the latter ; 

 basal margin deeply sinuate on either side, the lateral 

 angles produced posteriorly, very acute, medial lobe bi- 

 emarginate ; above very convex, smooth and shining, 

 inijiressed with a few minute punctures, only visible under 

 a deep lens ; basal margin faintly strigose, more or less 

 edo-ed with ])iceous; sides irregularly bordered with flavous, 

 the extreme lateral margin sometimes narrowly edged 

 Avith piceous; anterior margin narrowly edged with flavous, 

 impressed with a single row of deep punctures. (The 

 flavous markings on the sides and apex vary greatly in 

 different individuals, and are sometimes entirely obsolete.)
