ELATERIDiE. APLOTARSUS. 271 



broader than the base of the thorax, punctate-striate : legs pitchy-black, with 

 the base of the femora, the joints, and the tarsi more or less testaceous: an- 

 tennae black. 

 Female; — N. G. cordiger. Steph. Catal. 126. No. 1277: rather larger and 

 broader, with the antenna? shorter. 



Not common within the metropolitan district ; the only locality 

 where I ever met with it being- in a lane leading from Birch to 

 Daren th-woods : it is found in Somersetshire, in Suffolk, and near 

 Edinburgh. " Among herbage on Crwmlyn-burrows, not common."

Genus CCXXIX. — Aplotarsus* miki. 



Antennae moderate, slightly serrated, naked; the basal joint slightly incrassated; 

 the second short, subglobose; third rather longer, and more slender, than 

 the fourth, which, with the six following, is obconic ; the terminal one elon- 



[" gate lanceolate-ovate. Palpi filiform, with the terminal joint ovate-sub- 

 truncate : mouth porrect : head transverse ; forehead with the anterior margin 

 reflexed: thorax elongate, narrowed anteriorly, the sides margined, disc 

 slightly convex ; posterior angles carinated, slightly prominent: body slightly 

 pilose: elytra sublinear, a little convex : legs slender ; tarsi gracile ; the four 

 basal joints simple, gradually diminishing in length, the fourth being shortest ; 

 claws simple, very slender. 



From Caloderus the present genus may be distinguished by 

 having the third joint of the antennae elongated, the palpi nearly 

 filiform, the thorax elongate, very slightly convex; and from the 

 two following by having the tarsi slender and the fourth joint not 

 minute. 



Sp. 1. testaceus. Niger, elytris striatis pedihusque testaceis. (Long. corp. 3^—4, 



lin.) 

 El. testaceus. Fabricius.—'N. G. testaceus. Steph. Catal. 127. No. 1289. 

 Elongate : head and thorax immaculate, slightly shining, black ; the posterior 



angles of the latter very acute : elytra finely striated, the interstices thickly 

 • but finely punctulate, testaceous, immaculate: legs entirely pale-testaceous : 



antenna? dusky, with the basal joints slightly testaceous; mouth piceous. 



I possess one example of this rare insect from Mr. Hall's col- 

 lection, and a pair from the vicinity of Bristol : it occurs also 



near Edinburgh.
