20 CLAVICORNIA. [Ampliicyllis. 



Britain ; it resembles Leiodes in form, but is easily distinguished by the 

 4-joiuted club of the antennae (the club of Leiodc.s being 5-jointed with 

 the second joint very small) and the non-spinose posterior tibiae ; it is 

 jil so related to Agathidium, but the latter genus is less globose and has 

 the club of the antemue 3-jointed, and the mesosternum keeled instead 

 of tuberculate. 



A. g-lobus, F. Very convex, almost hemispherical, head and elytra 

 sinning black, thorax bright red ; antennae red, with the two middle 

 joints of the club blackish ; head thickly and finely punctured, mouth 

 parts red ; thorax at hinder margin more than double as broad as long, 

 plainly narrowed in front, anterior angles rounded, posterior angles 

 obtuse, thickly and finely punctured ; elytra rather distinctly punctured, 

 with a deep sutural stria reaching from apex to about middle ; meso- 

 sternum tuberculate at apex; legs reddish-brown, posterior femora often 

 blackish. L. 2|mm. 



Male with the three first joints of the anterior tarsi and the two first 

 joints of the intermediate tarsi widened and pubescent beneath ; female 

 with all the tarsi 4-jointed. 



In dead leaves, faggot stacks, rotten wood and fungoid growth ; not common, but 

 occasionally occurs in numbers ; Woking, Caterham, Coombe Wood, Darenth Wood, 

 Chatham, *Purley Down, Wimbledon, Duhvich, Highgate, Sheppy ; Essex ; Hastings ; 

 New Forest ; Church Stretton ; Sherwood Forest ; Northumberland district, very 

 rare, Gosforth and Long Benton ; not recorded from Scotland. 



V. feiTugineum, Sturm. This variety is entirely rufo-ferruginous ; 

 it is less common than the type form ; I have taken it near Lincoln and 

 it has occurred at Ripon and in other localities. 



XiXODES, Latreille (Anisotoma, Keitter et auct). 



This genus contains about a dozen species from Europe and North 

 America, four of which are found in Britain ; like Anisotoma they have 

 a 5-jointed club with the sixth joint very small, but they may be dis- 

 tinguished from that genus by their more hemispherical shape, and by 

 having the mesosternum tuberculate at apex and not carinate ; they are 

 also, as a rule, larger and dark-coloured, occasionally being furnished 

 with yellow spots on the elytra. 



The larva of L. glabra (Anisotoma glabra) is described and figured by Schiodte, i. 

 37, Pi. x. fig. 7. It is very like that of Choleva fusca, but is more parallel-sided and 

 more gradually narrowed behind ; the head projects, but is small, and very much 

 narrower than the prothorax ; the three thoracic segments are very transverse, of about 

 equal si/e, with the angles rounded, and with strong muscular impressions; the 

 abdominal segmeuts are much contracted iu front and behind, and gradually decrease 

 in breadth : the ninth segment is about as long as broad and cylindrical, and bears a 

 vi-ry >hort anal appendage and two long cerci; legs and antenna? short; this larva is 

 pule xvith the corneous parts fuscous ; it is found in fungi. I have retained the name 

 of Liodes for this genus, although Roitter and several authors have changed it to 

 , as the interchange of theuanu'S of genera gives rise to so much contusion ;
