b. The thorax anteriorly broader than the head. 

 Sp. 2. villosus. Brunneus, subnitidus, longius pallido pilosus, thorace ovato, ere- 



berrime cequaliter punctato, elytris profundi punctato-striatis, interstitiis sub- 



tilius seriato-punctatis. (Long. corp. 1^ — if lin.) 

 Bo. villosus. Paykul. — To. villosus. Steph. Catal. 144. No. 1458. 

 Brunneous, slightly shining, clothed with elongate pale-griseous hairs : thorax 



ovate, thickly and regularly punctate : elytra deeply punctate-striate, the 



interstices flat, and each with a row of minute impressions : antennae and legs 



pale testaceous. 

 Also variable in colour, being more or less ferruginous, or pale testaceous. 



Not very common in the vicinity of London : it also occurs in 

 Somersetshire and Devonshire. " On the bark of oak, not un- 

 common (near Swansea)." — L. W . Dillzoyn, Esq. 



Sp. 3. micrographus. Ferrugineus, nitidus, subpubescens, thorace oblongo, antice 

 scahro, elytris subtilissime punctato-striatis, apice obtusis, muticis. (Long, 

 corp. 1^ lin.) 



Bo. micrographus. Paykul.— To. micrographus. Steph. Catal. 145. No. 1459. 



Ferruginous, shining, slightly pubescent: thorax oblong, rough anteriorly and 

 opaque, finely punctulated posteriorly, but towards the middle of the base 

 nearly smooth and glossy: elytra very delicately punctate-striate anteriorly, 

 the striae nearly evanescent posteriorly. 



The oblong thorax, nearly naked body, and scarcely striated elytra, are the chief 

 characters of this insect. 



Not common : I have found it near Hertford. 



f Sp. 4. flavus. Flavo-testaceus, subpubescens, thorace oblongo, crebre punctata, 



elytris subtilissime punctato-striatis. (Long. corp. 1£ lin.) 

 To. flavus. Wilkin MS S.— Steph. Catal. 145. No. 1465. 



Testaceous-yellow, slightly pubescent and glossy : the thorax oblong, produced 

 anteriorly, the disc sprinkled throughout with rather coarse punctures : elytra 

 faintly punctulate-striate, the interstices flat, each with a series of minute 

 punctures: antennae and legs pale ochraceous, or testaceous. 



I believe the only known examples of this species were taken 

 either in Norfolk or in the New-forest. 



B. "With the elytra retuse behind, and frequently dentate. 



a. The elytra not dentate posteriorly. 



Sp. 5. fuscus. Fusco-piceus, longius pubescens, thorace antice, scabro, opaca, 



elytris cylindricis, confertissime punctato-striatis. (Long. corp. 1 — lg lin.)
