94 MANDIBULATA. — COLEOPTERA. 



rowly margined : elytra each with two red spots, one at the middle of the 

 base sinuated, trilobed, the other a little behind the middle transverse-ovate : 

 legs black ; tarsi piceous : antennae black. 

 Larger than the foregoing, but smaller than the following, from which it differs 

 in having the spots on the elytra of a brighter red, and the posterior one 

 nearly divided in its centre. 



Found beneath the bark of birch and sallows, in various places 

 within the metropolitan districts, as Bexley, Coombe, Windsor, 

 Hertford, <kc. ; but not common. " Near West Farley, in Kent, 

 by Rev. W. Kirby."— Marsh. MSS. " In rotten wood, Bottisham, 

 rare." — Rev. L. Jenyns. 



Sp. 3. quadripunctata. Nigra nitida, elytris maculis duabus rubris ovatis sim- 



plicibus remotioribus. (Long. corp. 2| — 3 lin.) 

 Ni. quadripunctata. Herbst. — Ips quadripunctata. Steph. Catal. 90. No. 964. 



Curtis, vii. pi. 306. 



Subovate, glossy-black, finely punctured, rather convex : thorax with the disc 

 convex, the lateral edges broadly and the posterior narrowly margined, the 

 base nearly as broad as that of the elytra ; the latter ovate, with the apex 

 rounded, each with two ovate pale reddish spots, the anterior in the middle 

 of the base, the other, rather behind the middle, transverse: legs pitchy-cas- 

 taneous, with the tarsi paler. 



The remote, ovate, entire reddish or orange spots on the elytra of this insect, 

 which is the largest in the genus, at once point out its distinction from its 

 congeners. 



Rare : found near Windsor ; in the New Forest, &c, beneath 

 the bark of the birch. 



B. Body elongate cylindrical. 



Sp. 4. ferruginea. Lineari-elongata, siibcylindrica, convexa, punctatissima fer- 

 ruginea, capite obscuriori. (Long. corp. 2^ lin.) 



Der. ferrugineus. Linne. — Ips ferruginea. Steph. Catal. 90. No. 961. 



Linear-elongate, subcylindric, pale ferruginous, shining, thickly and rather 

 deeply punctate ; head rather fuscescent, eyes black: antenna? ferruginous, 

 with the club dusky: thorax quadrate, convex, slightly margined: elytra 

 linear, the apex truncate, with a single stria at the suture. 



Found beneath the bark of dead pine-trees : it has occurred near 

 Norwich, and in other parts of Norfolk; also in the vicinity of 

 Manchester. 



Genus CLIV. — Nemosoma, Latreille. 



Antenna; rather longer than the head, the basal joint stout, ovate; the second 

 less robust, short; the five following very short, gradually incrassated; the
