10 Mr. G. Lewis on 



very minutely and sparsely punctulate, stria complete, bowed 

 laterally, nearly straight in front, vertex feebly impressed ; 

 the thorax, marginal stria very fine, lateral also very fine, it 

 widens out a little in the median area, and, although very 

 fine, continues round the basal angle, on each side not far 

 from the margin and as near the middle as possible is a small 

 black spot ; the elytra, striee 1-3 complete, 4-5 dimidiate 

 and exactly equal in length, there is no sutural ; the pygidia 

 are punctured like those of P. latimarginatum. 



Beneath, this species is almost exactly the same as the last, 

 except that the surface of the prosternum on either side 

 of the keel is less conspicuously strigose and there are no 

 short striae at the mesosternal angles ; the anterior tibite are 

 5-dentate, basal tooth very small. 



This and the preceding species with P. constnctuni, Lew., 

 constitute a type of Platysoma peculiar to Australia. The 

 prosternal anterior lobe is very prominent in all the three 

 species.

Pheltster m'gropunctatus, sp. n. 



Ovalis, convexiusculus, rufo-brunneus, nitidus ; pronoto utrinque 

 nigro-punctato ; elytris striis 1-4 integris, 5 et suturali basi 

 abbreviatis; propygidio pygidioque punctatis ; tibiis anticis 4-

L. 2f mill. 



Oval, a little convex, rather dark reddish brown, shining ; 

 the forehead is clearly punctulate, feebly concave, stria com- 

 plete, carinate over the eyes, nearly straight in front ; the 

 thorax, marginal stria complete, crenulate behind the head, 

 lateral stria tine, parallel to the marginal stria, and ter- 

 minating just before the anterior angle, surface finely not 

 densely punctured, near the middle but not very close to the 

 lateral margin is a distinct but small circular black spot ; the 

 elytra, the bases are narrowly edged with black, and near 

 the scutellum there are six or eight small black spots, and 

 behind them the suture is dusky, the striee are crenulate, 1-4 

 complete, 5 and sutural reaching beyond the middle, the 

 sutural is the longest; the propygidium and pygidium are 

 somewhat closely punctured, punctures shallow, the pygidium 

 has a narrow posterior rim; the prosternum, anterior lobe 

 somewhat closely punctured, keel smooth, with two oblique 

 stria} between the coxee ; the mesosternum is widely sinuous 

 anteriorly in the middle, with a short sinuosity on either side 

 of it : across the mesosternum is a fine arched stria, which
