ridge or line near the suture, terminating posteriorly in a 

 number of small granules, a series of about six more or less 

 elevated longitudinal lines, dotted with granules, on the rest of 

 the elytron, one" of these between the suture, which is also 

 marked by a similar line, and the ridge, the remainder, of 

 Avhich the second and fourth are the most prominent, exter- 

 nally, the intervals of the lines minutely punctured in two 

 rows ; body beneath and legs glossy chestnut-brown. Length 

 9 lines. 



Broader than P. i^iceus^ Y^xxhj, and strongly differentiated 

 from every other species by the sculpture of its elytra. 



Pterolielceus aselliis. 



P. ovalis, utrinque paiilo incurvatus, fuscus, vix nitidus ; prothorace 

 obsolete punctato ; el}i:ris liueatim leviter punctatis, marginibus 

 latitudine omuino sequalibus. 



Hob. Queensland (under bark of fallen trees) . 



Oval, the outline equally rounded and rather obtuse at botli 

 extremities, the sides a little incurved, moderately convex, 

 blackish brown, scarcely shining ; head and prothorax covered 

 with exceedingly minute punctures, the margins of the latter 

 gradually passing into the disk ; scutellum transversely and 

 curvilinearly triangular ; elytra linearly punctured, the punc- 

 tures rather small, the fifth and eighth intervals between the 

 lines a little broader than the rest, the margins concolorous, 

 narrow, of equal breadth throughout, and agreeing with those 

 of the prothorax ; body beneath and legs glossy brown ; an- 

 tennaj short, the last joint nearly circular. Length 4^-5 lines. 



Resembles P. lyeltatus^ De Br., but much more convex, 

 nearly opaque, the margins of the prothorax and elytra much 

 narrower and concolorous with the rest of the upper surface. 



Helceus'* Master six. 



H. late obovatus, fuscus, squamositate grisea tenuiter tectus, setu- 

 lisque erectis nigris instructus, in utroque elytro carina acute 

 elevata, apicem baud attingeus. 



Hah. Western Australia (Salt River, under stones). 



Broadly obovate, dark brown, 'covered with a loose greyish 

 dust-like squamosity and furnished above with short erect 

 black bristles ; eyes approximate, nearly covered by the pro- 

 thorax ; the latter impunctate, nearly semicircular, not narrowed 

 at the base, the margin broad, slightly concave, the centre 

 with a narrow very distinct longitudinal ridge not quite ex- 

 tending to the base ; scutellum transverse ; elytra as broad at
