of A. ohesa, and as sucli was expunged from our lists (Ent. Annual 

 1859, p. 122); Mr. Rye, however, in reintroducing the species (Ent. 

 ^Monthly Mag. IX. 135), discusses the whole question, and proves 

 satisfactorily that it is distinct ; in fact it is more closely related to A. 

 calcarata than to A. ohesa, from which latter it is easily distinguished, 

 among other points, by the singly curved posterior tibiae of the male, 

 the less dilated anterior tibiae, and the relative length of the second 

 and third joints of the antennae: from small specimens oi A. calcarata 

 it may be known by the truncate hind margin of thorax, and more acute 

 posterior angles of the same, as well as by the unarmed posterior tibiae ; 

 it somewhat resembles A. litura, but may be easily separated from that 

 species by the narrower and entirely ferruginous club of the antennae, 

 and the comparatively wider apical joints. 



A, clavicornis, Rye. Oval, convex, ferruginous-testaceous, thorax 

 not very closely punctured, with sides evenly rounded, truncate at base, 

 elytra rather coarsely but not deeply pimctured ; distinguished from all 

 other species by the structure of the antennae, which are very short, 

 gradually widened towards apex, with the fourth, fifth, and sixth joints 

 unusually small, and the apical joints, though short, as wide as the two 

 preceding, which are very transverse. L. 2\ mm. 



This species was described by Rye from a single specimen taken in flood refuse on 

 the banks of the Nith, near Tbornhill, Dumfries, October, 1873, by Dr. Sharp ; it 

 has occurred since in France and Southern Europe. 



A. punctulata, Gyll. {litura, Steph., ornata, Fairm.). Oblong, 

 ferruginous, with the head and thorax often more or less pitchy, and 

 the elytra, as a rule, with the suture, and a more or less defined streak on 

 each side, darker ; occasionally almost the whole insect is of a dark 

 pitchy colour ; antennae moderate, with the club rather long, fuscous or 

 blackish ; thorax a little narrower at base thari elytra, with the sides 

 very gently rounded, posterior angles almost right angles, upper surface 

 finely and not very closely punctured ; elytra with strongly punctured 

 striae, interstices scarcely visibly punctured, except for the large punctures 

 in the alternate ones. L. 2|-3 mm. 



Male with the posterior legs elongate, the femora unarmed, and the 

 tibiae rather strongly curved. 



By evening sweeping in autumn among dead leaves, in flood rubbish, &c. ; local 

 but not uncommon in some places ; Mi. kleham, Caterham, Shirley, Forest Hill, High- 

 gate, Darenth ; Folkestone ; Hastings ; Glanvilles Wootton ; New Forest ; Burton- 

 on-Trent; Lincoln; Hartlepool; Northumberland district, rare, Wallington, Gosforth, 

 &c. ; Scotland, Lowlands, rare, Solway, Forth, and Dee districts; Ireland, Port- 

 mannock. 



A. calcarata, Er. Oblong ovate, ferruginous, with the head and 

 thorax sometimes somewhat darker, exceedingly variable in size : head 

 thickly and finely punctured, antennae moderately long, with fuscous 

 club, last joint narrower than penultimate : thorax not quite as broad
