and less scattered ; the prosternum is rather broad and dilated at 

 the base ; the mesosternum is sinuous anteriorly and distinctly 

 angulate on either side, and the short marginal striae follow the 

 course of the angles ; the anterior tibiae are 4 -dentate. 



The species is in many respects similar to H. indica, Er., but in 

 Erichson's species the pygidium is densely punctured and the 

 mesosternum is not so conspicuously angulate laterally.

11. Platysoma lignarium, Lewis, sp.n. 



Oblongum, subparallelum, parum convexum; fronte concava, 

 labis transversa, stria transversa Integra sed tenuiter impressa ; 

 pronoto stria laterali baud interrupta, valida ; elytris, striis dor- 

 salibus 1-3 integris, 4-5 et suturali apicalibus ; propygidio 

 transversim punctato ; pygidio parum dense ocellato - punctato, 

 margine postice elevato ; prosterno hand striate ; mesosterno, 

 sinuate, marginato ; tibiis anticis 4-dentalis. 



Long. ^ 4'5-5 mm. 



Oblong, somewhat parallel, little convex, black, shining, legs and 

 tarsi reddish brown ; the head, forehead concave, labrum trans- 

 verse, stria complete but fine ; the tliorax transverse, rounded off 

 at the anterior angles only, marginal stria very fine and ceasing 

 near the eye, lateral stria strong, with the interstice uniform in 

 width, not narrowing at the base, and distinctly wider than that 

 of P. bzrmanum, Mars. ; scutellar puncture linear ; the elytra, striae, 

 inner humeral fine, basal, and oblique, outer humeral wanting, 

 1-3 dorsal strong, parallel, and complete, 4 apical, and not 

 reaching the middle, 5 shorter, not half the length of the fourth, 

 and with a wdder space between it and the apex ; sutural com- 

 mences behind the middle of the dorsum, and reaches only to 

 a point on a line with the anterior part of the fifth ; the pro- 

 pygidium has ocellate punctures transversely arranged, which leave 

 a smooth margin along its edges both before and behind; the 

 pygidium is closely punctured, punctures ocellate, hinder margin 

 strongly elevated; the tibiae, anterior 4-dentate, intermediate 4-5, 

 posterior 3-spinose. 



This species belongs to the same group as Platysoma odio.mm, 

 Mars., and in its oblong, rather parallel form, it resembles 

 P. suturale. Lew. 



S^ah. — Eound in rotting wood on the coast and in the central 

 part of the island. 



12. Paromalus, sp. 



There is a single example in this collection of an apparently 

 undescribed species ; it has a large and deep round fovea in the 

 centre of the pygidium, and is therefore probably a male. 



Mab. — In rotting wood.
