the lower limb of the humeral crescent slopes towards the apex of the elytrum ; 

 the broken or S-sbaped band terminates in a streak at the margin ; all the 

 uarkings also of the elytra are buflF coloured rather than white; and the 

 minute mucro or point that terminates the suture, and the serrulations of the 

 apex of the elytra are less conspicuous. 



De Jean regards this species as synonymous with C hiriicollis, but, if I 

 am correct in my reference to him, of which I have little doubt, they are 

 clearly distinct. 



3. CiciNDELA Proteus, Kirby. — Length of body 5f lines. This species 

 of which several specimens were taken in the expedition, appears to abound 

 in North America, Dr. Bigsby met with it in Canada, and there was a 

 specimen in the late Mr. Marsham's collection, probably from the United 

 States. 



Similar to C. repanda, but instead of ths humeral and terminal crescents, 

 in all the varieties, are four white dots, two at the base and two at the apex 

 of the elytra ; the middle broken or tortuous band resembles the figure 7 

 reversed, and does not terminate in a marginal streak. The body underneath, 

 as usual, is golden-green, or green with clouds of blue, above it is dark-brown 

 with a tint of copper. 



Variety B. With the apical dots not larger than the humei^V. 

 6*. With an interrupted crescent at the apex. 



D. With three apical and two humeral dots ; intermediate band 



internally abbreviated. 



E. Like the last, but with only one humeral dot. 



[This is C. duodecim-guttataj Dej. ; it is commonly taken in many parts 

 of Canada.] 



* Labrum trideniate. 



[10] 4. CiciNDKLA. OBLiQDATA, De Jean. — Many taken in the expedition, 

 and apparently abundant in North America. I received it many years since, 

 but without a name, from my lamented friend Prof. Peck. 



Body above greenish-copper, underneath golden-green clouded with blue. 

 Labrum white, tridentate, slightly prominent in the middle; mandibles white 

 at the base, black at the tip; palpi black; labial with the intermediate joint 

 rufous, darker at the tip. Elytra with a large white humeral crescent, ex- 

 tended at the lower end obliquely beyond the middle; mesal band bent down, 

 wards, recurved at the end, and connected by a marginal line with a crescent 

 at the apex. In the male the intermediate joint of the labial palpi is white, 

 and the mesal band is not connected with the terminal crescent. 



[Le Conte (Pro. Acad. Nac. Sci. Phil., Dec. 1866, p. 362) states that this 

 species should hereafter be known as C. Kirhyiy since, as he learns from a
