masticatory margin strongly dentate ; clypeus lightly tectiform, the 

 medial lobe shortly produced, the anterior margin nearly trans- 

 verse ; autennal carinae as in C. compressus : antennae short, slender, 

 the scape not extending to the top of the head. Thorax in profile 

 arched above the apex ofc' the metanotum, truncate; the legs long, 

 the posterior tibiae not prism-shaped, slightly compressed, almost 

 cylindrical. Node of pedicel cuneiform, broad and transverse above ; 

 abdomen liigh, convex, anteriorly steep and rounded. 



g min. Kesembles the mo/., the head proportionately not 

 so massive, the scape of the antennae longer, reaching above the 

 top of the head ; the arch of the thorax slighter and continued 

 down almost to the apex of the metanotum, which is very slightly 

 truncate ; pedicel and abdomen proportionately smaller but similar 

 to those of the $ maj. 



" $ . Wings light brownish yellow, with bright brown nervures. 

 Metanotum like the legs, yellowish red. Mandibles with 6 teeth. 

 For the rest similar to the maj." (Forel.)

" . At first sight closely resembles C. marginatus, Latr. (fallax, 

 Nyl. ); like that species it is black, with reddish antennal joints 

 (especially of the tiagellurn) and tarsi : coxa; yellow. The erect 

 pubescence is yellow, moderately long and not dense on the thorax, 

 but on the other hand very dense on the head, the sides of which 

 are set with a thick row of hairs, and beneath the hair is very long 

 and voluminous. Tibiae of the legs and scape of the antennae with 

 erect hairs. Head unusually elongate, quadrangular, with the sides 

 parallel, emarginate posteriorly and polished, lightly transverse 

 behind, in front very feebly and finely punctured like a net. Node 

 of pedicel polished, oval above, rounded or nearly truncate. Abdo- 

 men transverse rugose, yellow and globose. Legs brown, without 

 erect hairs. 



" $ . Entirely resembles the , though the sides of the head 

 are not so richly pubescent as the upper and under sides, perhaps 

 the hair is only abraded. Wings light yellow. 9 mm. long. The 

 node of the pedicel is lightly emarginate above." (Roger.)
