248 MANDIBULATA. — COLEOPTERA. 



Sp. 7. variabile. Lineari-elongatum, rufo-ferrugineum, aut testaceum, ienue 

 pubescens, antennis longitudine corporis, thorace obsolete tuberculato, elytris 

 subtiliter punctulatis, sape violaceis. (Long. corp. 4 — 8 lin.) 



Ce. variabilis. Linne.—Cs\. variabile. Steph. Catal 200. No. 2043.— Ce. fenni- 

 cus. Martyn, C.pl.Q5.f.\6. 



Linear-elongate, xwio-ferrugineous or testaceous, slightly pubescent : thorax obso- 

 letely tuberculated, generally immaculate, sometimes spotted with black: 

 vertex occasionally black : elytra violet, very finely punctured, the lateral 

 margin in rare cases ferruginous : breast and base of the abdomen sometimes 

 black, as is also the club of the femora : antennas as long as the -body, rufo- 

 ferruginous, vpith the tips of some of the lower joints occasionally dusky. 



Extremely variable, both in colour and size : some examples are black, with the 

 mouth, antennae, tip of the abdomen, base of the femora, tibiae, and tarsi, fer- 

 ruginous, with the elytra violet : others have these last luteous, with the apex 

 alone violet, and the legs piceous : and in some instances the entire surface 

 is pale rufo-testaceous : these are probably immature, and form the Cal. testa- 

 ceum of my Catalogue, No. 2044. 



Also rare : I have twice taken specimens near London; once in 

 my own garden, in July last, flying in the evening. " Epping." —

Sp. 9. russicum. Plate xxii. f. 2. — Lineari-elongatum, nigrum, thorace 

 rotundato tuberculato, elytris fiavo-testaceis macula media apiceque nigris. 

 (Long. corp. 42 lin.) 



Ca. russicum. Fabricius. — Steph. Catal. 200. JVo. 2050. 



hinear-elongate, black, slightly pubescent : thorax rounded, with the disc punc- 

 tate and tubercular : elytra rather thickly punctured, ivith the base pale yeUow- 

 testaceous, the apex black, with a faint violet tinge, and on the disc a rounded 

 patch of a similar hue : legs rather slender, black : tarsi pale rufo-testaceous; 

 antennae short, deep black : labrum dull luteous. 



Of this beautiful species, which appears to agree with the short 

 Fabrician description of Ca. russicum, — though by its violaceous 



f Sp. 8. luridum. Brevius, subdepressum, thorace nigro nitido subcanaliculato, 



elytris opacis (scepe testaceis) elevato lineatis. (Long. corp. 5 lin.) 

 Cal. luridum. Fabricius.— Turton (!).— Steph. Catal. 200. No. 2048. note. 



Variable : short, depressed, finely punctured : thorax shining black, a little 

 channelled in the middle, with a more or less obsolete irregular rufescent
