reside in damp places, beneatli stones, dead leaves, or the decaying 

 bark of trees. 



Sp. 1. cephalotes. Niger, thorace capitis latitudine, elytris antice rujis, apice 

 nigris, suiurd TnacuMque transversa suhlunatd communi, scutello pedibusque 

 rufis. (Long. corp. 3 — 3^ lin.) 



Ba. cephalotes. De Jean.— Curtis, iii. pi. 139. — Stcph. Catal. No. 97. 



Generally rather larger than the next : head large, almo&t as broad, or broader, 

 than the thorax, black : thorax short, pale rufous, slightly notched anteriorly, 

 attenuated behind, with a slight longitudinal line and an impression at each 

 posterior angle: scutellum and elytra also pale rufous, the latter with the 

 hinder half blue-black, the suture, a transverse lunule, and the outer margin 

 pale rufous: body and head beneath black, thorax rufous, legs and palpi 

 ochraceous, antennae the same, with the basal joints piceous at the tips. 



This insect, until recently, was preserved in the collections of 

 the Rev. W. Kirby and Mr. Haw^orth only : it is, however, now 

 in many cabinets, having been found in several places in the neigh- 

 bourhood of the metropolis, at Darenth, Birch, and Coombe woods, 

 Shooter's-hill, Battersea-iields, &c. ; so that it is apparently less rare 

 than presumed, and illustrates the positions laid down in page 17 *. 



Sp.2. bipustulatus. Niger, thorace capite latiore, elytris antice rvjis, apice 

 nigris, suturd mactddque rotundatd aut triangulatd communi thorace pedi- 

 busque rufis. (Long. corp. 2^ — 3i lin.) 



Ca. bipustulatus. Fahricius. — Don, xv. pi. 516. — Pa. bipustulatus. Steph. 

 Catal. No. 98. 



Varies considerably in size : head rounded, black, narrower than the thorax, 

 which is rufous, slightly attenuated behind, and deeply notched anteriorly ; 

 with a strong longitudinal line, and a rounded impression at the basal angles; 

 it is obsoletely wrinkled transversely : scutellum black : the elytra rufous 

 anteriorly, with the suture and margin paler; on each a broad semilunar 

 cyaneous-black mark, leaving a round or triangular rufous spot within to- 

 wards the suture : body and head beneath black : thorax and legs rufous : 



* I may here observe, with reference to my observations in the above page, as 

 an instance of the facility with which novelties may be obtained by individual 

 exertion, that in the short space of forty days, between the middle of June and 

 beginning of August last, I captured, in the vicinity of Ripley, above 2400 

 species of insects, exclusively of larvae, &c. or nearly one-fourth of our ascertained 

 entomological productions, amongst which, although upon old explored ground, 

 were about 100 new species, not before in any collection, so far as I have in- 

 spected, including several perfectly novel genera, many of considerable size; 

 and amongst the known insects, several reputed scarce were in considerable 

 plenty, as hereafter detailed.
