DESCRIPTIONS OF NEW SPECIES OF AUSTRALIAN COLEOPTERA. 



Part xvii. 



By Arthue M. Lea, F.E.S. 



(One Text-figure.) 



NITIDULIDAE. 



Cychbamus fimbbiatus, n. sp. 



c?. Dull eastaneous-brown, parts of appendages somewhat paler, club in- 

 fuscated. Moderately clothed with short, depressed ashen pubescence, inter- 

 spersed with longer, subdepressed and somewhat reddish hairs; a conspicuous 

 fringe on each side. 



Head with dense and sharply-defined but rather small punctures, becoming 

 stiU smaller on clypeus; labrum deeply incised. Antennae with third joint elon- 

 gate, club almost circular. Prothorax evenly convex, base about thrice as wide 

 as the median length, sides strongly rounded and very feebly margined, hind 

 angles rounded off, apex about half the width of base, deeply emarginate, the 

 emargination straight across middle, oblique on sides; punctures much as on head. 

 Elytra, when at rest, with outlines continuous with those of prothorax, scarcely 

 longer than the basal width, sides evenly diminishing to apex; punctures as on 

 prothorax, non-striated. Intercoxal process of prosternum truncated posteriorly, 

 middle and hind coxae widely separated. Fifth segment of abdomen notched at 

 apex, and with a small conical process there, sixth segment small, circular, and 

 slightly concave. Legs stout, three basal joints of front and middle tarsi wide, 

 of the hind tarsi rather thin. Length, 6.25 mm. 



Hah. — Queensland: Cairns (E. Allen), unique. 



The marginal fringe is dense and even on each side from apex of prothorax 

 to apex of elytra, but gradually decreases in length from apex to base of pro- 

 thorax and from base to apex of elytra, it is continued, but more irregularly and 

 with longer hairs to tip of abdomen; it causes the species to be the widest in 

 proportion of aU Australian Nitidulidae known to me. On the type, portion of 

 the propygidium is exposed. 



MALACODERMIDAE. 



Metriorrhynchu.s hexastichus, n. sp. 



c?. Sooty-brown; sides of prothorax, and sides and tips of elytra flavous. 

 Head with vei-y short muzzle. Antennae long and rather thin, moderately
