biarcuate, the pvosternnm acuminate at the apex, the meso- 

 sternura with a triangular incision, and the pygidium more 

 densely punctured, o — Sh lines. Found in the sap (jf rotten 

 trees in S. Sweden. I have specimens from Weston-super- 

 Mare and Lincolnshire (T. V. Wollaston) which agree with 

 tlie above description, as also with a type sent by M. Thom- 

 son himself. 



5. H. merdarius, E. H. (1803), Mars. 297. — Elytra with 

 four dorsal striae entire; tibiae 4-dentate ; antennae with the 

 club ferruginous ; pygidium strongly punctured. 3 lines. 

 More oblong than the preceding, recalling the shape of neg- 

 lectus. Spread over Europe and the Mediterranean, but 

 everywhere rare. My specimens come from the London 

 district. 



H. Jiuietarius, Hb. — A beauliful and distinct species; 

 the elytra have each a large oblique red spot. It is widely 

 distributed over Europe, but ai)pears to be wanting in Sweden 

 as well as here. 



6. H. negleclus, Germ. (1813), Mars. 531. — Oval, a little 

 elongate ; elytra with three dorsal striae entire, the fourth 

 slightly abbreviated ; pygidium densely punctate ; frontal 

 stria sinuate. S^- — 3 lines. Europe, Asia and Africa; no- 

 where rare. The elongate form separates it from nearly all 

 its congeners. 



7. H. varhonarius, E. H. (1803), Mars. 534. — Elytra with 

 three dorsal striae entire, the fourth abbreviated beyond the 

 middle ; pygidium rather sparingly punctured ; prosternum 

 smooth, acuminate. 2g- lines. Very abundant. M. de Mar- 

 seul, regarding this a& a composite species, has separated H. 

 ignobilis and H. ventralis ivom it. The former should be 

 larger, with several deep punctures at the anterior angle of 

 the thorax, and the pygidium nnich more strongly punc- 

 tured. The latter should be still more suborbicular in 

 form, and have a broad equal margin to the thorax, not 

 raised or thickened. I have seen nothing in this country to 

 answer this description as yet. H. nigellatus, Germ.^ is also 

 a liitle like carbonarius, but has the fourth dorsal entire, and 

 the prosternum with two basal striae. It appears to be a 

 fungus-feeding species. 



8. H. pnrpurasceiis, Hb. (1792), Mars. 537. — Elytra with 

 an ill-defined red apical spot, three dorsal striae entire, and
