40 MATERIALS TOWARDS A HISTORY 



74. C. scutellaris, Oliv., iv. pi. v. fig. 52. Encyc, v. 267. 



Black, pronotum obtusely carinate, with a narrow, transverse medial, and an anterior and posterior narrow, 

 yellow band; elytra with the base rufous, and having two obliquely curved, and one transverse yellow band. 

 5i'" long; li wide. Hah. Pennsylvania, Virginia, July— Carolina, June. 



C. eleeans, Mete. Cat., 812. Boston Collection, 573. Head surrounded posteriorly with a narrow, yellow- 

 band; front with two vertical yellow bands; antennas rufous: elytra tapering rapidly; tip obliquely truncate, 

 with a spine exteriorly; first elytral band curving obliquely outwards from the scutel to the margin, when it 

 extends forward alonn- the side, the second curves in an inverse direction from the margin to the suture about 

 the middle, and the third is midway between this and the tip: feet slender, rufous, femora clavate, extremity 

 black, the posterior ones extending beyond the elytra: venter with four broad, yellow bands. 



The curved lines on the elytra present the appearance of four separate quadrants placed 

 together, with the convexity inwards. 



75. C. pubescens, Drj. Cat. 



Uniform dull reddish-brown, sparsely covered throughout with yellowish hairs; elytra conjointly emarginate, 

 with a spine at tip, externally. — 8"' long. Hab. Pennsylvania. % Cab. Melshcimer. $ Cab. Le Conte. 



Head with a wide frontal groove: prothorax large, tapering very gradually forwards, scabrous and trans- 

 versely rugous above, without dorsal line: elytra tapering rapidly, minutely rugose, with confluent punctures, 

 and endiu" in a spine near the outer margin; sutural hairs sufficiently dense to form a light-coloured line which 

 is crossed by two others, at a third of the distance from the base and apex, and there is another line of hair in 

 a short, humeral impression: feet and beneath hairy, femora extending a little beyond the elytra. 



7G. C. GRAMINEUS, Klllg. 



Dull brown, cinereous hairy beneath; elytra with several indistinct yellowish irregular transverse lines, apex 

 truncatc-emarginate, with a small spine towards the external side. G" long; 2 wide. Inhabits Oregon. 



Body short and robust, pronotum transversely rugulose, widest behind the middle, whence it narrows sud- 

 denly and obliquely to the base of the elytra. Cab. Le Conte. 



77. C. vespoides, Dcj. Cat. 



Reddish-brown, base of the antenna?, feet, and base of the elytra rufous; prothorax subglobose, anterior and 

 posterior margins, with the scutel, yellow; four transverse yellow bands. 5'" long; If wide. Georgia. 



Robust, mctathorax with a yellow spot laterally: segments of the venter margined with yellow: elytra with 

 the basal band interrupted, the second directed obliquely outwards and backwards, and placed before the mid- 

 dle, the third one-fourth the distance from the apex, the fourth apical. Cab. Le Conte. 



This species, as well as others noticed in this paper, may be figured in the monograph 

 ol'Castlenau and Gory on this genus, a work which I have not seen. 



?S. C. campestris, Oliv., iv. pi. 70, fig. 95. Id., villicus? fig. 94 — colonus? Fair. Syst. 

 El., ii. 345. Encyc, v. 259. 



The larva docs considerable damage to fallen chestnut timber, which is extensively 

 used in the construction of fences. The younger individuals burrow between the bark 

 and the wood, where the larger ones arc also found, but in general they penetrate beneath 

 the surface. The perfeel insect appears in May and June, and has been found from 

 .Massachusetts to Carolina and Mississippi. — Bost. Coll., 579. 



79. C. rhombifer, Oliv., pi. 7o, (!) fig. 51. a. b. Georgia. 



80. C. caprea, Say. Ann. I'.nl , pi. 5:;. Mass., Penna., Virginia, Missouri, New Orleans.
