82 Mr. Arthur M. Lea's Revision of the 



interspaces with regular double rows of fairly large tro,nsverse punc- 

 tures, separated by distinct ridges, the longitudinal ridges separat- 

 ing the punctures at base fully as distinct as the regular costae, but 

 beconiing smaller (although still regular and distinct) from about 

 the basal fourth. 

 Length 14 mm. 



Hah. N.S. Wales : Tweed R {W. W. Froggatt). 



A very distinct species. Mr. Froggatt sent with this 

 species a specimen which resembles it in size, colour and 

 general appearance to a remarkable extent, and yet it 

 belongs to the Oedemeridae. As a description may be of 

 interest, this is appended as a footnote.* 



Metriorrhynchus simsoni, n. sp. 



^ Black ; shoulders and tips of elytra reddish-testaceous. 



i^os^nimalmost absent. Antennae passing hind coxae, very strongly 

 serrate but not ramose ; 2nd joint indistinct even from the sides, 

 3rd joint perceptibly longer than 4th. Prothorax distinctly 7-areo- 

 late ; not much wider than long, base not much wider than apex 

 and almost right angled, middle constricted. Scutellum, transverse, 

 apex semicircuiar. Elytra each quadricostate ; the insterstices with 



* PSEUDOLYCHUS WALLACEI, n. Sp. 



Black ; basal three-fifths of elytra of a dark brownish-red Clothed 

 with short pubescence varying from greyish to black ; each of the 

 abdominal segments tipped with very distinct white pubescence. 



Head with small concealed punctures. Antennae broad, extend- 

 ing to basal third of elytra ; 1st joint as long as eye and much 

 shorter, 3rd-10th strongly serrate, gradually decreasing in length 

 and width, 11th thinner and longer than 10th. Frothorax slightly 

 transverse, apex rounded, base slightly bilobed, sides feebly incurved 

 to middle, disc with obtuse subtubercular elevations. Scidellum 

 longer than wide. Elytra considerably wider and about six times 

 longer than prothorax ; sides and suture thickened and the disc of 

 each with three distinct costae, interspaces more or less convex and 

 with dense partially concealed punctures. Legs long ; basal joint of 

 hind tarsi longer than the rest combined, of the front tarsi almost 

 as long as the three following combined, of the middle tarsi much 

 shorter ; claws obtusely lobed at base. 



Length 14 mm. 



Hah. N.S.Wales: Richmond River (TF. W. Froggatt). 



Readily distinguished from haemorrJwldalis and the allied species 

 by the four apical joints of antennae not becoming suddenly narrower 

 than the others. The prothorax lias altogether ten subtubercular 

 elevations; of these a moderately long one is on each side of the 

 median line, two (irregular and partly conjoined) are on each side of 

 the base and two (very indistinct) on each side of the apex.
