wider than prothorax, parallel-sided to near apex, with regular 

 rows of fairly large punctures becoming smaller posteriorly, inter- 

 stices with minute but fairly numerous punctures. Intercoxal 

 process of prosternum ridged along middle, a narrow groove on 

 each side, base gently bilobed. Claws strongly and acutely 

 dentate. Length, 6|-7 mm.

The general outlines are much the same as thoss of the species 

 of Platymela, but the intercoxal process of the prosternum, whilst 

 not conspicuously bilobed as on most species of Calomela, has not 

 the gentle, even incurvature between the outer edges of its base 

 as on the former. It is much the shade of colour of C. mono- 

 chromatea, but the head is bimaculate and the knees metallic; 

 the outlines, except that the sides of the prothorax are more 

 rounded, are much as in C. geniculata, C. flaveseens, and C. 

 cephalotes. The metallic colour of the legs is more extended on 

 one specimen than on another. At a glance, the elytral punc- 

 tures, of the two specimens under examination, appear to be 

 much larger than they really are, their apparent width being 

 almost equal to the interstices between them, but this is due to 

 "waterlogging"; their true size may be readily noted from an 

 oblique direction. 



Calomela vacillans, n.sp. 



Qastaneo-flavous, apical third of antennae infuscated. 



Head with dense and moderately large punctures ; clypeal 

 suture distinct. Antenna rather short, sixth to tenth joints 

 transverse. Prothorax more than twice as wide as long, basal 

 two-thirds almost parallel-sided; sides with coarse and rather 

 dense punctures, becoming much smaller and sparser in middle, 

 with minute ones scattered about. Elytra slightly wider than 

 prothorax, sides very gently rounded; with rather coarse punc- 

 tures in places in very irregular series, on apical slope smaller, 

 and behind shoulders larger than elsewhere. Intercoxal process 

 of proster7Uim grooved towards, and deeply notched at, base. 

 Length, 5 J mm.
