36 cr.AvicoRMA. [Anisofoma. 



A. rus-osa, Step}). Short oval, moderately convex, ferruginous or 

 brownish-red, shining ; head and thorax thickly and distinctly punctured, 

 antennae comparatively long, with rather a long club, the last joint of 

 which is much narrower than the penultimate, and is rather long and 

 pointed ; thorax at base slightly narrower than elytra, narrowed in front, 

 base truncate, posterior angles obtuse and almost rounded ; elytra oval, 

 rounded at sides, with rather feeble and not strongly punctured stria?, 

 interstices very plainly transversely rugose, and besides this more or less 

 distinctly punctured ; the alternate interstices are also furnished with 

 lai-ger punctures ; legs red. L. 3-4 mm. 



Male with the posterior legs elongate, the femora dilated and rounded 

 at apex, and the tibiae strongly curved. 



By evening sweeping; very rare ; London district (Stephens and Janson) ; Cater- 

 liain (Champion); Weybridge; Mickleham (Power); Scarborough (Lawson) ; 

 Hartlepool (Gardner) ; Northumberland district, banks of the Irthing, near Gilshm.l ; 

 Ireland, North Bull, near Dublin. 



A. parvula, Sahib. A very small species, which can only be com- 

 pared with A. badia from which it is easily distinguished by the dis- 

 tinct cross striation of the interstices of the elytra ; the thorax moreover, 

 which is impunctate on disc in A. budia, is finely punctured throughout ; 

 the sculpture of the elytra is much finer and the posterior legs are longer ; 

 the form is short oval and convex : antennae rather long, with the club a 

 little darker; thorax rather short, base truncate, posterior angles sharp 

 right angles, upper surface very finely punctured ; elytra with finety 

 punctured striae, interstices cross-striated ; legs simple in both sexes. 

 L. 1-1| mm. 



By evening sweeping in woods ; rare ; Chatham, Darenth Wood, Mickleham, 

 Caterham, Esher, Whitstable ; Bognor ; Glanvilles Wootton ; Plymouth ; Scotland, 

 rare, Solway, Tweed and Forth districts ; it probably occurs in many other localities ; 

 it is usually uncommon but is somewhat widely distributed in Northern and Central 

 Europe. 



GROUP 2. 



This group contains the two rare species A. ciliaris and A.furr'i, which 

 are distinguished from those of the preceding group by having the side 

 margins of the elytra set with distinct outstanding hairs ; they may be 

 also easily recognized by their short and stout dilated posterior tibiae, 

 which hardly extend to the apex of the elytra, a point in which they 

 differ from all the other species of the same size : A. badia has rather 

 short posterior tibiae, but they are scarely dilated, and the whole insect is 

 of an entirely different appearance and much smaller : it is important that 

 these characters should be carefully noted, as the short hairs on the 

 margins of the elytra of A. furva are apt to get rubbed off. 



I. Side margins of elytra set with long hairs ; thorax 



broadest just behind middle ; size smaller; colour lighter. A. CILIARIS, Schmidt. 



II. Side margins of elytra set with short hairs ; thorax 



broadest just before base ; size larger; colour darker . . A. FDBVA, Er.
