I have given the description of this insect, but there is considerable 

 doubt and difficulty regarding the species and its allies, and it is pro- 

 bable that we have two or three at least of the European species standing 

 under the name of C.fulva in our collections. Continental specimens 

 of 0. fulva, which have been kindly sent me by M. Brisout, have the 

 thorax distinctly more transverse and less narrowed behind than is tlie 

 case with many of our English specimens ; I have specimens from Dr. 

 Power that agree with these, but a series in Dr. Sharp's collection stand- 

 ing doubtfully under 0. fulva have the thorax about as long as broad 

 and more narrowed behind ; in this respect they agree with C. impressa, 

 but the sculpture of the elytra is that of O. fuloa, to the description of 

 which species they answer better than the continental specimens before 

 alluded to. 



I have before me two specimens from Mr. Matthews' collection which 

 have been returned to me by M. Brisout as new species near linearis ; 

 one of these appears to be distinct, but is broken and rather dis- 

 coloured, and the other appears to me only a small and rather 

 abnormal variety of C. fulva ; the thorax of many species of the 

 Lathridiidse is very variable, and any person who felt so inclined 

 might easily describe five or six new species on this and other 

 differences out of any large series of Corticaria. 



C. obscura, Bris. (depressa, Thorns.). "This species is allied to 

 C. serrata, but differs in being rather larger, of flatter and less oval 

 build, larger antennal club, laterally less rounded thorax (of Avhich the 

 denticulations are finer behind, and the punctuation is not quite so close), 

 and less evidently pubescent but more finely punctured elytra, — the 

 interstitial rows and the striae themselves being equally delicate, and 

 so close that the surface seems to be very delicately transversely 

 sub-strigose " (Rye, Ent. Mo. Mag. vii. 274) ; the elytra, moreover, 

 appear to be rather depressed and parallel-sided ; the colour is usually 

 pitchy-black, but appears to be variable. L. l|-2 mm. 



Under dry bark; Eichmond Park (Rye and Champion) ; Esher (Power). 



There is some doubt regarding this species, which Dr. Sharp omits 

 from his last catalogue. 



C< elong'ata, Humm. Sublinear. depressed, testaceous, clothed with 

 thick pale pubescence, which is rather longer and arranged in rows on 

 the elytra ; head much narrower than thorax, forehead rather convex ; 

 eyes black, prominent ; thorax evidently transverse, about as broad as
