290 CLAVICORNIA. {_Cortlcaria. 



preceding species, colour variable, usually fusco-ferrugiuous, upper 

 surface clothed with fine greyish pubescence ; head not much narrower 

 than thorax, eyes large and prominent ; antennge rather short, testaceous, 

 with the first two joints of the club scarcely longer than broad ; thorax 

 a little broader than long, with the sides rounded and more strongly and 

 acutely denticulate than in the allied species, narrowed towards base, 

 posterior angles with a strong crenulation ; elytra oblong-ovate, only a 

 little broader than thorax at the broadest part, with regular rows of 

 punctures, and moderately distinct interstices which are not carinate, 

 and are somewhat wrinkled, and furnished with rows of smaller punc- 

 tures ; abdomen with fifth ventral segment not deeply foveate ; legs 

 rufo-testacnous. L. 1| mm. 



Male with the anterior tibife very slightly sinuate internally towards 

 apex, and the first joint of the anterior tarsi a little dilated. 



In haystack and other refuse, under bark, &c. ; also in ants' nests ; not common ; 

 Chatham, Esher, Forest Hill, Peckham, Cowley ; Weybridge (in neat of Formica 

 rnfa); Horsell (in nest oi F.fuliginosa) ; Loughton ; Hainault Forest; Horning 

 Fen; Cambridge; Reptou ; Northumberland district; Scotland, rare, Sol way and 

 Tay districts. 



The.small size, and transverse thorax which has the sides strongly crenu- 

 lated, together with the sculpture of the elytra, will separate this species 

 from all its allies ; it most closely, perhaps, resembles C. crenuJafa, but 

 that species has the thorax longer and more regularly rounded, longer 

 antennae, less regularly punctured elytra, and the femora of the male 

 incrassate. 



C. umbilicata, Beck (cylindrica, Mannli. ; horealis, Woll ). 

 Ferruginous or ferrugino-testaceous, clothed Avith rather short and dis- 

 tinct pubescence ; head large, eyes large and very prominent ; thorax 

 suborbicular, about as broad as elytra, with sides evidently crenulate ; 

 elytra long, parallel and cylindrical, with regular and distinct jDunctured 

 strige, interstices almost impunctate ; the suture and sides of the elytra 

 are sometimes more or less infuscate. L. l|-2 mm. 



In moss, &c. ; occasionally by sweeping ; very local, and as a rule scarce ; Strood, 

 Kent, taken in abundance by Mr. Champion and Mr. Walker; Wimbledon; 

 Shooter's Hill; Chattenden Roughs; New Forest; Northumberland and Durham 

 district, not rare, sea-banks ; Scotland, very rare, Aberdeen (Professor Traill). 



C. fulva, Com. (hirfeUa, Thoms. ; flavescens, Thoms.). Kather 

 elongate, about as large as C. crenulata, but rather narrower than that 

 species, with the thorax cordiform, and the elytra with the shoulders 

 more gently rounded and the apex less acuminate ; colour entirely tes- 

 taceous, excepting the eyes, which are black ; these latter are less 

 prominent than in most of the other species ; the elytra are elongate- 

 ovate, evidently broader than the thorax, Avith the sculpture consisting 

 of rows of large and shallow punctures, which are rather confused and
