44 Mr. F. P. Pascoe on new Genera and Sjpecies of 



Rather broadly oval, brownish blacky shining ; head thickly 

 and roughly punctured^ clypeal groove well defined, narrowly 

 and sharply limited, the transverse portion above curved 

 downwards ; prothorax minutely but not very closely punc- 

 tured, rounded at the sides, the expanded margins not recurved, 

 the irregular basal groove on each side nearly obsolete ; scu- 

 tellum broadly triangular, its apex rounded ; elytra a little 

 contracted behind the shoulders, finely, but not minutely, 

 seriate-punctate, the punctures less regularly arranged near 

 the suture and base ; body beneath and legs glossy brownish 

 black, the propectus opaque, granulate ; antennae short, the 

 third joint nearly twice as long as the fourth. Length 

 6-7 lines. 



Broader and much less finely punctured than the last spe- 

 cies, and not particularly glossy, &c. In some collections it is 

 labelled P. striato-jpunctatus^ Boisd.; but the same objection 

 applies to this as to P. mtidissimus. Both species have the 

 abdominal segments finely striated longitudinally (a character 

 common to many Tenebrionidge) and the clypeal grooves well 

 marked. 



Pterohelmas litigiosus. 



P. paulo anguste ovalis, ferrugineo-fuscus, nitidus ; clypeo antice 

 late emarginato, sutura indistincta; elytris teniiiter striato- 

 punctatis. 



Hah. Sydney. 



Rather narrowly oval, rusty-brown, shining; head finely 

 punctured, a little concave in front ; clypeus broadly emarginate 

 anteriorly, separated from the front by a narrow indistinct 

 line ; prothorax very minutely punctured, a short longitudinal 

 groove near the apex, none at the base, the expanded margins 

 not recurved; scutellum transversely triangular; elytra cal- 

 lous at the base, rather finely seriate-punctate, the intervals of 

 the rows slightly raised, the fourth and eighth intervals rather 

 more so than the others, the expanded margins narrow ; body 

 beneath, legs, antennas, and margins of the prothorax and 

 elytra reddish ferruginous. Length 7 lines. 



In colour and outline resembling P. silj)]ioides^ but rather 

 broader, and not dull brown as in that species, the intervals 

 of the stride more elevated, the punctures larger, and, above 

 all, a broad callosity at the base of the elytra. 



Pterohelceus alternatus. 

 P, subanguste ovalis, niger, nitidus ; clypeo antice vix emargiiiato,
