ENGin^E. — CORTICARIA. 107 



La. crenulatus. Sch'ippel— Co. crenulata. Steph. Catal. 93. No. 988. 



Colour variable, pitchy or ferruginous-brown, or black, or testaceous; dusky- 

 pubescent : thorax rather short, rounded, truncate at the base and apex, the 

 lateral margins equally rounded, and scarcely narrowed posteriorly, very obso- 

 letely crenated ; the disc slightly convex, rather thickly punctulate, with a 

 more or less distinct fovea at the base, behind the middle ; elytra as in the 

 last species, but less transversely rugose. 



Smaller than the foregoing, with the thorax shorter in proportion; its sides 

 more regularly rounded, less crenate, and the elytra less evidently transversely 

 rugose. 



Also found within the metropolitan district ; in Battersea-fields, 

 and at Hertford I have frequently taken it. " In dry fungus, 

 Walham Green." — Mr. Waterhouse. 



Sp. 3. denticulata. Fusco-picea, brevius pubescens, thorace breviore rotundato, 

 lateribus obsoletiiis crenato, elytris simpliciter punctato-striatis, interstitiis 

 vix rugulosis. (Long. corp. 1 lin.) 



La. denticulatus. Schllppel. — Co. denticulata. Steph. Catal. 93. No. 989. 



Fusco-pieeous, or variable in colour, like the two foregoing ; rather shortly pubes- 

 cent, with the thorax as in the last, the sides being obsoletely crenate; the 

 elytra also of similar form, slightly convex, very sparingly pubescent, each 

 with eight distinct striae, with the interstices impunctate and very obscurely 

 rugose : legs rufo-testaceous. 



Closely resembling the preceding, but less pubescent, and the interstices on the 

 elytra destitute of punctures. 



Found near London, less abundantly than the foregoing. 



Sp. 4. longicornis. Nigra, subnitida, tenue pubescens, antennis pedibusque rufes- 

 centibus, thorace longiore, cordato, lateribus mutico, elytris simpliciter punc- 

 tato-striatis. (Long. corp. 1 lin.) 



La. longicornis. Herbst. — Co. longicornis. Steph. Catal. 93. A r o. 990. 



Black, rather shining, slightly pubescent: thorax rather elongate, with the 

 lateral margins considerably dilated and rounded before the middle, smooth, 

 not crenate, towards the base slightly narrowed ; the disc moderately convex, 

 thickly punctured, with an obsolete slightly impressed fovea behind the 

 middle at the base: elytra with the shoulders and apex rounded, each with 

 eight punctate striae, the interstices impunctate, but finely rugulose trans- 

 versely: body beneath glossy black, with the breast punctate: legs rufo- 

 testaceous, with the femora sometimes dusky : antennae with the basal half 

 rufescent, the rest dusky. 



This species is distinguished by being nearly as large as Co. pubescens, and by 

 having the sides of the thorax entire, smooth, the interstices on the elytra 

 impunctate, &c. 



Found within the metropolitan district.
