CICIJS T DEEIDiE. 



The species may be known from C. aurofasciata by the less 

 coarse punctuation of the head and pronotum, the more parallel- 

 sided and flatter elytra, the different markings, and, as a rule, 

 by the colour of the labial palpi. I have, however, found these 

 last with the base light in one specimen of C. aurofasciata, 

 although they are usually dark ; so this cannot be regarded as a 

 constant character, and occasionally the humeral patch in the last- 

 named species appears to be abbreviated as in C. princeps. 



The species is rather closely allied to C. shivah, but the latter 

 insect is smaller and more parallel-sided, with the head and pro- 

 notum less coarsely sculptured, and the latter more or less plainly 

 angled just before the anterior constriction; the underside, more- 

 over, is much more pubescent, and the yellow markings are much 

 smaller and different. 



Yar. dncalis, W. Horn. 



According to Dr. Horn this variety differs from the type in 

 having the elytra longer and narrower, and the elytral markings 

 less yellow, the humeral spot being smaller, much narrower and 

 oblique, and the central fascia being placed in the middle and not 

 just behind it and not curved at the suture ; the apical linear spot 

 also is much narrower. 



Length 16-22 millim.

The shape of the pronotum appears to be very variable in both 

 C. princeps and C. aurofasciata. Both these species are compara- 

 tively sluggish and are easily captured by hand.

This species is intermediate between C. princeps and C. sliivali. 

 From the former it differs in its much longer and narrower form, 

 and in having the sides of the pronotum less rounded, straighter 

 in the middle, and with the angles near the apical constriction 

 very prominent and almost right angles ; the humeral spot is 

 rather smaller than in the typical C. princeps, and the central 

 transverse fascia is placed more towards the apex and is narrower 

 and cut off at some distance before the suture ; the posterior 

 lateral angle of the central portion of the metasternum with the 

 coxal margin is thickly pilose ; the femora are bright cyaneous. 

 From 0. shivah it differs in having the labrum furnished with a 

 yellow spot, and the pronotum much narrower and not pilose at 

 the margins ; the elytra are a little broader, with the sutural angles 

 forming sharp right angles and not rounded ; the markings are 

 somewhat different, the central fascia being placed much more 

 towards the apex, and the apical spot being smaller and narrower 

 and distant from the sutural angle ; the underside is much less 

 pubescent. 



Length 22 millim.
