Platydema sulcato-punctatum, n.sp. 



Oval, convex, black, sub-nitid; antennae, legs and underside retl. 



Head closely and rather coai-sely punctate, epistoma arcuate in front, its 

 surface depressed below that of foreliead, the latter with a strongly raised longi- 

 tudinal ridge bounding each eye. Prothorax sub-truncate (from above) at apex, 

 bisinuate at base, sidies arcuat-ely narrowed from base to apex, anterior angles 

 depressed and romided, posterior acute; disc densely punctate, without any sign 

 of a medial line, the ordinary basal foveae replaced by longitudinal sulci. Scutel- 

 lum large, semi-circulai', punctate. Elytra ovate, of same width as prothorax at 

 base, each with about 9 sulci containing small, elongate punctures at the base of 

 each sulcus, the intervals steeply convex between thase and themsedves covered 

 with small punctures. Dimensions : 4i x 2 mm.

A single male was amongst some beetles neieeived from the veteran collector 

 from a region that seems to produce endless species. It is of the general shape 

 and size of P. striatum Montr., but differe widdy from that species in its densely 

 punctate, sub-opaque surface, and its costate elytra! intei-vals. Type in Coll. 

 Carter. 



P'i'KROHEL.iEUS ASSUIILI.S, n.Sp. 



Ovate, moderately convex, nitid black, antennae and legs red. 



Head minutely punctate, eyes widely separated, antennae with four apical 

 joints transverse. Prothorax very transverse, widest at base, thence arcuately 

 and strongly narrowed to apex, anterior angles prominent but rounded at tips, 

 posterior acute, disc microseopically punctate with marked transverse depression 

 near base, beside.s small basal foveae, foliate margins wide and slightly concave 

 within. -Scutellum. transverse, semi-elliptic. Elytra of same width as prothorax 

 at base, foliate margins wide at base, gradually narrowing to apex, irregularly 

 seriate punctate with about 15 rows of punctures, uneven in size and unequally 

 spaced, those near sutui'e small, the punctures greatly increasing in size outwards, 

 thie external row containing large, closely-set pimetures; the intervals on sutural 

 half not, or scarcely, raised; on lateral half three or four intervals irregularly 

 convex; all inter\'als smooth and impimctate. Prosternum minutely punctate, a 

 few large punctures round middle coxae, abdomen finely striolate. Dim.ensions : 

 11-12 X 6-6i mm.

I took seven examples under decayed fig-tree bai-k in July, 1921, and at 

 fii-st assumed them to be P. pusillus Mael. which is common at Kuranda and 

 which it resembles in general fades. The following comparison is desirable for 

 distinguishing the two species: — 



P. pusillus Mael. P. assimiUs, n.sp. 



Less nitid, more oval and convex. More nitid and oblong. 



Antennal club of 5 joints. Club of 4 joints. 



Elytra, with geminate series of nearly Punctures xmeven in size and position, 



equal sized punctures between convex intervals of equal width — except near 



intervals, the alternate intervals cos- sides, where some iiTegularly raised 



tate. and wider intervals occur. 



P. asellus Pasc. is also allied, but its surface is more opaque than tJhat of 

 P. pusillus, the elytra have finer but regular seriate punctures, the alternate inter- 

 vals are wide but not raised. Types in Coll. Carter.
