from the margin by any raised space, very coarsely punctured. 

 Scutellum small and smooth. Elytra rather depressed, not a 

 great deal broader than thorax, punctate-striate ; sides somewhat 

 parallel and margined, black, with two rather transverse fulvous 

 spots, the one near the base extending transversely across the 4th, 

 5th, 6th, 7th and 8th interstitial spaces, the other near the apex 

 extending obliquely and transversely backwards over the same 

 interstices ; the spots pretty regular, but the colour on the 5th 

 and 7th interstices most extended, particularly in the anterior 

 spot ; the coloured spaces not raised, nor of a different texture 

 from the rest of the elytra; the interstices finely punctate, some- 

 what flattened on the disk, but very convex towards the sides ; the 

 marginal space marked with cross-punctures. Under-side black, 

 pilose, hairs piceous ; prosternum and breast deeply punctured, 

 inferior margin of thorax impunctate; segments of abdomen 

 finely acicularly punctured, with one or two deep fovese or large 

 punctures on the sides of the basal segments; inflexed margin 

 of elytra almost impunctate. Legs black and pilose. 



This species is allied to the Cr. selenoderus of Laferte, but 

 may be at once known by its much greater size, it being fully a 

 third larger.

Black. Head rather broad, closely covered with small punc- 

 tures, which become confluent here and there, particularly in 

 two fovese on each side of the head; space in front (clypeus) 

 impunctate, smooth and shining, with one large puncture on 

 each side. Antennae piceous, darkest at base. Palpi ferruginous. 

 Thorax obcordate, very uniformly covered with punctures smaller 

 than those in any of the preceding species, which become faint 

 and disappear towards the margin near the posterior angles; 

 the margins are expanded and very slightly reflexed, and at the 

 anterior portion they have a narrow edging or border; anterior 

 angles projecting and rounded-in to the neck, truncate at the 

 base; posterior angles slightly projecting backwards, and with a 

 slight exterior excision at the point ; middle portion of base also 

 very slightly projecting backwards ; the dorsal line is distinct, 

 except b(;hind, and there is an elongate straight depression at
