LATHRIDIID/E. 11^ 



a*. Thorax much narrower than elytra^ 

 scarcely ti\ansvei'se, broadest before 

 middle ; elytra more rounded at 



sides ; pubescence not conspicuous . C. loxgicollis, Zett. 

 b*. Thorax not much narrower than 

 elytra, strongly transverse, broadest 

 at middle ; elytra less rounded at 



sides ; pubescence conspicuous . . C. chenicollis, Mannh. 

 b. Thorax finely punctured, elytra par- 

 allel-sided ...... C. EL0XC4ATA, Gljll. 



III. Elytra with rows of short erect bristles, 



parallel-sided and cylindrical . . . C, umbilicata, Beck. 



C. linearis, Payk. (Faun. Suec. i. (1798), 302). Rather elongate, 

 slightly convex, moderately shining, with very fine and thin decumbent 

 pubescence ; head and thorax black, elytra pitchy black or brownish- 

 black with the shoulders ferruginous, antennteand legs ferruginous, the 

 club of the former sometimes darker ; head narrower than the thorax with 

 very short but distinct temples ; antennae with joints 4, 5, and G a little 

 longer than broad, 7th and 8th globose, the first two joints of the club 

 as long as broad ; thorax much narrower than elyti-a, about as long as 

 broad, evenly more or less rounded and feebly dentate at the sides, 

 rather strongly and thickly punctured, with a deep round fovea before 

 the middle of the base ; elytra oblong, with the shoulders rounded but 

 almost rectangular, and with rather well-marked callosities, somewhat 

 depressed, broadest in the middle, rather strongly punctured in rows, 

 and with much finer rows of punctures on the interstices ; male with 

 the anterior tibiae very feebly curved on their inner side behind the 

 apex, first joint of the tarsi dilated, fifth ventral segment ^•ery feebly 

 impressed at apex. L. lf-2 mm, 



Bradfield, two specimens (Joy) ; the species occurs in Northern 

 Europe and North Asia, and also in Germany and Austria in mountainous 

 districts on pine and fir trees. 



This insect may be known from C. serrata by its proportionately 

 narrower thorax, with the sides much less strongly serrate, and by 

 the more depressed and more parallel-sided elytra. 



C. epelsheimi, Reitt. (Stett. Ent. Zeit. 1875, 423). Exceedingly 

 closely allied to C. linearis, but distinguished by its entirely ferruginous 

 or reddish-yellow colour and more convex elytra, which are more 

 strongly rounded at the shoulders, and also by the fact that the inter- 

 stices of the elytra are more or less distinctly rugose transversely ; the 

 antenna?, moreover, are slightly longer and more slender and the 

 humeral callosities are less developed. L. l|-2 mm. 



Woking (common in powdery fungi on fir stumps during one 

 season only) and New Foiest (Chan)pion) ; Ganglbauer mentions the 

 species as " very rare," and as occurring in Finland, Austria and 

 Germany.
