 extremity Avhich is furnished with a distinct tooth. 



In hot-beds, vegetable refuse, moss, &c. ; often by sweeping ; generally distributed 

 and common throughout England, but apparently becoming scarcer towards the 

 north ; Scotland, local, Forth district ; Ireland, near Dublin, &c. 



Xi. ang-ulatus, Humm. (angusticollis, Thorns, et Britt. auet., nee 

 Humm. ; undtdatus, Mots.). Ferruginous brown, rather shining, con- 

 siderably smaller than the preceding species, which in some points it 

 resembles ; head and thorax rugosely punctured, the former Avith a 

 distinct longitudinal furrow, the latter very narrow, longer than broad, 

 with the margins irregular and the anterior angles lobed ; elytra oval,

 to be distributed throughout Europe and the Caucasus region, and to be the com- 

 monest species in Germany, Austria, and Hungary. 



(It. ang-usticollis, Humm., nee Thorns. This species is at once 

 distinguished from the preceding by the absence of the rows of short 

 erect setae on the elytra ; it appears to be intermediate between L. lar- 

 darius and L. angulatus ; it is smaller than the first, and has the elytra 

 obtusely rounded at apex, and besides is of a darker colour ; besides the 

 absence of the elytral setae, it may be distinguished from the latter by 

 its more robust form, and by having the thorax shorter, more even, and 

 more visibly narrowed behind. L. 2 mm. 



I know of no British specimen of this insect, and it cannot, I think,
