84 SERRICORXIA. \GatdioplhanUk 



prosternal process is truncate behind, and the anterior coxal cavities 

 are rather narrowly open. 



The larva of Cardiophorut aellus is described and figured by SchiiV.Ite (Part v. 

 p. 494, tig iv. 1-10) ; it is very lone, slender and filiform, and is chiefly remarkable 

 for the very great proportional length of the abdomen, which is due to the fact that 

 the abdominal segment*, which are transverse ami much broader than the thoracic 

 segments, are separa'ed by retractile membranous joints, the space occupied by these 

 between each segment being longer than the segment ; the ninth abdominal segment 

 is narrow, with a tuft of hairs at apex and a reflexed hook on each side ; the head is 

 oblong with bifurcate mandibles, scarcely narrower than the thoracic segments, which 

 are very small in comparison with the rest of the body ; the legs are moderately long 

 nnd plainly visible from above ; the colour is white, with the thoracic segments 

 flavescent, the head ferruginous, and the mandibles fuscous. 



There are four species, which have been reputed as British, but 

 throe of these are doubtfully indigenous, and require further conforma- 

 tion before they can be received with any certainty. 



C. asellus, Er. (eqm'seti, Steph., nc Herbst.). Of a greyish-black 

 colour, somewhat thickly clothed with rather long recumbent greyish 

 pubescence, thorax moderately shining, elytra dull ; form somewhat 

 resembling that of Agriotes sputator and its allies ; head thickly 

 punctured, with vertex impressed, antennae black, gradually narrowed 

 to apex ; thorax very convex, with sides rounded, thickly and very 

 finely punctured, posterior angles short and blunt ; scutellum large, 

 eordiform, with a deep impression ; elytra somewhat depressed and 

 uneven on disc, subparallel until posterior third and thence narrowrd to 

 apnx, with distinct punctured striae, interstices very thickly punctnn-d, 

 dull ; legs black, knees and tarsi lighter, claws simple. L. 6-8 mm. 



Sandy places; at roots of grass and by sweeping herbage; very local and, as a 

 rule, rare ; occasionally, however, it has been taken in some numbers, Eslier, 

 Faversham, Frensham, Woking, Chobham, Birch Wood, Darenth Wood ; Wey- 

 ini.iith and Portland ; Chesil Beach, common, May 1886 (J. J. Walker) ; Glanvilles 

 Wootton ; Bristol ; Scotland, Edinburgh (Stephens) ; the latter record may have 

 been in error, as it has not since occurred in Scotland or in any district in the 

 Midlands or North of Kugland. 



(C. riifaollis, Er. Shining black, indistinctly clothed with greyish 

 pubescence, upper surface of thorax red, with the anterior portion 

 black, under surface of the same red with the anterior edge and a 

 longitudinal streak, black; head finely punctured; thorax as long as 

 broad, not very convex, thickly and finely punctured ; elytra broader 

 than thorax with strong punctured striae, interstices somewhat convex, 

 punctured and transversely wrinkled, upper surface black or bluish- 

 bhck, under surface black ; legs black, tarsi more or less brownish. 

 L. 5 1 mm. 



Rcc trded by Stephens from the neighbourhood of London, and also as having been 

 found on the oak in Norfolk.
