34 CLAVICORNIA. [Anisotoma. 



A. curta, Fairm. Oval, very convex, almost equally narrowed in 

 front and behind, of a shining testaceous reddish colour ; antennae short 

 with club slightly darker, stout and broad ; head usually darker than the 

 rest of the body, very finely and closely punctured ; thorax very convex, 

 not quite as broad at base as elytra, posterior angles obtusely rounded, 

 closely but distinctly punctured ; elytra twice as long as thorax, with 

 rather deep and closely and strongly punctured striae, interstices obsoletely 

 punctured, alternate rows with widely set larger punctures. L. 3-3 mm. 



Male with the posterior femora terminating in a blunt angle, or as 

 Fairmaire in his description says, " terminated above and below by two 

 small and slightly projecting teeth," * posterior femora curved. 



The species is closely allied to A. dulia, but is easily distinguished by 

 its rather longer build, the much stronger punctuation of its thorax, the 

 aides of which are more contracted behind, by the apical joint of the 

 antennae being distinctly narrower than the penultimate, and by the 

 different curvature of the posterior tibiae of the male. 



Sandy places, by evening sweeping under fir-trees, very rare ; one example tuken 

 by Mr. Champion at Esher, October, 1873, and one by the Rev. T. Laundy Browne 

 near Norwich ; it appears to be very common on the sandy coasts of Normandy, 

 and also occurs near Paris ; it will probably be found in numbers on onr south-east 

 coast. 



A. lunicollis, Rye. Oblong ovate, convex, shining, ferruginous ; 

 antennae with the club somewhat elongate, fuscescent, last joint distinctly 

 narrower than the penultimate ; thorax in middle a little broader than 

 elytra, ample and convex, sides strongly rounded, base truncate, upper surface 

 finely and moderately thickly, but distinctly punctured ; posterior angles 

 rounded ; elytra with rather strongly and thickly punctured striae, the 

 punctures being somewhat smaller than in some of the allied species, 

 interstices finely but distinctly punctured; intermediate and posterior 

 tibiae rather stout. L. 2f mm. 



Male with the intermediate tibiae dilated towards apex and slightly 

 curved, posterior femora produced in a lobe terminating in a tooth above 

 and below at apex, tibiae slightly curved. 



By evening sweeping, in flood refuse, &c. ; very rare ; Forest Hill (Marsh) ; 

 Sydenhain ( Wuterhouse) ; Cowley (Power); Scarborough (Lawsou) ; Hartlepool 

 (Gardner). This species is allied to A. calcarata, but differs in the more rounded 

 sides and ungles of thorax, and the truncate base of the same, and also in its more 

 oblong build, and closer set and smaller punctures of the striae of the elytra, as well 

 as by the less strongly dilated posterior tibisc of the male. 



A. tricpkei, Schmidt. Oval, moderately convex, lighter or darker 



* The descriptions of the male characters of Anisotoma often vary very much in 

 different authors; the posterior femora are usually dilated in a lobe, which from above 

 appears single, but in reality is double, being formed of two plates separated by a 

 groove, as will be seen by viewing the tibiae sideways ; the apex of each of these 

 plates is terminated by one or more teeth, or is obtuse or rounded ; sonic authors 

 dtbcribc the characters on one plate, some on both, and hcnco arises the contusion.
