100 8EURICOIINIA. [At/lOVS. 



Female broader, less parallel and more convex, with the thorax 

 broader and rounded and narrowed in front, and the antennae much 

 shorter; the elytra are considerably broader in proportion, and are 

 slightly widened before apox ; this sex much resembles at first sight a 

 light example of A. riffa/tia, but may at once bo known by the sculpture 

 of the thorax, which is much coarser and duller, and the very short 

 second joint of the antenna;. 



By sweeping herbage ; local ; rather common and generally distributed from tins 

 Midland districts southwards, but much 'rarer further north ; the mnle is usually 

 common where it occurs, but the female is always very scarce ; Northumberland dis- 

 trict, one female only taken at Gibside by Mr. J. K. Taylor ; Scotland, very rare, 

 Forth district, " Dalmeny Park, near Edinburgh," Murray's Cat. 



A. difformts, Lac. ( ? cavus, Germ.). Larger, more darkly 

 coloured, and more shining than the preceding species, with which it is 

 rather closely connected as far as structure is concerned ; the second 

 joint of the antennae, also, is longer in proportion, and the thorax is less 

 thickly punctured, with the central furrow less evident ; colour lighter 

 or darker reddish-brown, with the head and thorax often darker, the 

 sides and posterior angles being usually lighter than the disc, pubes- 

 cence fine, greyish ; head rather coarsely punctured ; thorax thickly 

 but not rugosely punctured; elytra with fine striae, interstices finely 

 punctured and more or less rugose transversely, especially in the male. 

 L. 9-10 mm. 



Male with the head deeply impressed, the antennae a little longer than 

 in female, and the thorax narrower, rectangular and parallel-sided ; the 

 elytra are narrower and more parallel, with the striae finer and the inter- 

 stices more rugose transversely. 



Female with the head not depressed, the antennae a little shorter, 

 with the first joint longer, and the thorax more finely punctured, with 

 the sides less parallel, somewhat rounded and narrowed in front, and 

 the anterior angles much less pronounced ; the striae of the elytra are 

 rather stronger, but the interstices are more finely and less rugosely 

 punctured ; this sex much resembles A. vittatus, but may be known by 

 having the thorax more finely punctured, and the sides straight and not 

 sinuate before the posterior angles. 



Grassy places by sweeping 1 , &c., especially at night ; for a long time it was con- 

 sidered one of our rarest British beetles, but has recently been taken in numbers by 

 Mr. Butler and others in the south of England; the female, however, appears to be 

 always very much scarcer; E:istry, Kent (Gorhain); Ramsgate, in alders (Stephens) ; 

 Shepherd's Well and Sandwich (\Vaterhouse) ; St. Peter's, Kent (T. Wood) ; Deal (C. 

 G. Hall) ; Hastings district, in numbers (Butler, Collett, &c.) ; one specimen is said 

 to have occurred at Newton, Devon. 



A. haemorrhoidalis, F. (ruficaudis, Steph.). Elongate, sub- 

 parallel, clothed with rather thick greyish pubescence, pitchy brown or 

 brown, with the head and thorax black, sometimes brown, but usually 

 darker than elytra, which are sometimes lighter brown ; head thickly
