28 CLAVICORNIA. [Anisotuma. 



shining, antennae moderate, ferruginous; thorax as broad as elytra, 

 closely punctured, much narrowed in front, posterior margin truncate, 

 hind angles rounded ; elytra with sides rounded, with rather strongly 

 punctured striae, each interstice with two more or less irregular rows of 

 very fine punctures, alternate interstices with larger punctures ; legs red. 

 L. 3^ mm. 



Male with the posterior legs elongate, the femora with an obtuse 

 tooth on each side at apex, and the tibiae curved, female with the 

 posterior femora terminating in an obtuse angle somewhat rounded. 



Very rare; Scotland, Forth, Clyde, and Tay districts; the few specimens captured 

 were all, or nearly all, taken by Mr. Foxcroft ; the species is one of the most distinct 

 of the wLole genus. 



A. dubia, Kug. Subovate, ferruginous or reddish testaceous, occa- 

 sionally quite pale, sometimes with the head and thorax pitchy, and the 

 elytra ferruginous, size also variable ; head thickly punctured, with 

 larger impressions on vertex ; antennae moderate, with 3rd joint half as 

 long again as 2nd, club darker or lighter ; thorax not quite as broad as 

 elytra, thickly punctured, rather long proportionally, with sides strongly 

 and evenly rounded, posterior angles very obtuse or rounded ; elytra with 

 strongly punctured striee, interstices very finely but not very closely 

 punctured, alternate ones with the usual larger punctures ; legs moderately 

 stout. L. 2-3f mm. 



Male with the posterior legs elongate, femora furnished at apex with 

 a small tooth on each side, tibiae feebly biarcuate ; female with the 

 posterior femora terminating in an obtuse angle at apex. 



By evening sweeping in woods, on sand-hills, &c. ; local, but not uncommon in many 

 places ; it is perhaps the most common British member of the genus except A. calca- 

 rata ; Chatham, Darenth Wood, Caterham, Mickieham, VVoking, Esher, Shirley, 

 Cooinbe Wood ; Harwich ; Deal ; Hastings ; Glanvilles Wootton ; New Forest ; Exeter ; 

 Repton, and other Midland localities ; Manchester district ; Hartlepool ; Holy Island 

 (in numbers), J. J. Walker; Mr. Bold records the capture of large numbers on the 

 sea-shore near Whitby in October and adds, " They were on a sandy slope, with head 

 to windward ; whence they came bothered me entirely." * Scotland, rather common, 

 Solway, Tweed, Forth, Tay, and Moray districts ; Ireland, Portuiarnock. 



The following varieties of this very variable species may perhaps be 

 mentioned : 



V. bicolor, Schmidt. Size smaller, head and thorax pitchy, elytra 

 ferruginous ; it occurs with the type. 



* It is probable that many of the Anisotomina which are now exceedingly rare, will 

 be found plentifully as their habits become better known : they appear to have a 

 great affinity for the sea-shore or the sand-hills adjoining, and many should perhaps 

 be looked for in late autumn : the capture of Hydnobius punctatissimus in very large 

 numbers by Mr. T. Wood near Kingsgate, quite late in the autumn of 1886, is an 

 example : A. ciliaris and Hydnobius Perrisii, and several of the commoner species 

 have occurred in numbers near or not far from the sea-coast.
