Leiopus hituberculatus, White, Cat. Long. Col. Brit. Mus. ii. p. 382. 



"L. punctulatus, cinereo-fuscus : antemiis subferrugineis : oculis 

 supra approximatis : elytris supra subplanis, arcu postmediauo ci- 

 iiereo, singulis ad basin medio tuberculo parvo uncinato, ad me- 

 diam et posticam partes cinereo variegatis ; femoribus basi palli-

 Long. 3i lines. Ega." (White, I. c.) 



This species very closely resembles L. circumflexum in shape 

 and colours ; but the centro-basal ridges are reduced to a tuber- 

 cle. The lateral thoracic spines are placed near the middle of 

 the thorax — the position they occupy in the genus Lophopceum ; 

 but the sides behind them are deeply sinuated, which gives the 

 thorax a similar shape to that possessed by the typical Leiopi. 



5. Lophopceum acutispine, n, sp. 



L. latiusculum, depressum, brunneum, postice cano marmoratum : 

 thoracis disco obtuse tuberculato : elytris apice sinuato truncatis, 

 angulo interne acuto, externo longe mucronato. Long. 5^ lin. 



Head and antennse dingy brown, basal joint of the latter 

 flexuous beneath. Thorax wide; disk obtusely tuberculated, 

 sides with the lateral tubercle very prominent and acute; coloui* 

 dingy olivaceous brown, silky. Elytra rather broad ; shoulders 

 prominent, lateral carina proceeding thence, strongly marked 

 and acute, apex rather broadly and transversely sinuate-truncate, 

 the internal angle acute, the external produced into a long tooth 

 or spine ; the centro-basal ridge not much raised, but surmounted 

 by a very higli crest of hairs ; the surface is coarsely punctured 

 only near the base ; the colour is the same as that of the thorax, 

 but the posterior half is marbled with light grey. Body beneath 

 silky brownish ; legs the same, varied with gi'ey. The basal 

 joint of the tarsi is a little longer than the two following taken 

 together. 



Para ; on dead branches in the forest.
