736 NEW SPECIES OF AUSTKALIAN COLEOPTERA, xiv., 



tenth equal in length, eleventh somewhat longer. Prothorax 

 with front angles somewhat rounded, sides thence parallel to 

 base ; with punctures as on head ; median line well defined 

 tow^ards base, but feeble in front. Elytra with crowded, asperate 

 punctures about base, becoming less crowded and more sharply 

 defined posteriori}^; striation distinct throughout. Hind cooi:(e 

 evenly and strongly narrowed to sides, greatest length about 

 equal to that of second abdominal segment; basal joint of hind 

 tarsi about as long as the rest combined. Length, 4| mm. 



Hab. — W.A. : Mount Barker (R. Helms); unique. 



In general appearance, strikingly close to F. siUuralis, but 

 readily distinguished by the comparative lengths of the third 

 and fourth joints of antennae. The pubescence on the under- 

 surface appears ashen or blackish according to the point of view; 

 on the upper surface, it is almost entirely dark. 



Fornax castaneus, n.sp. 



Castaneous, tarsi somewhat paler. Densely clothed with 

 short, stramineous pubescence. 



Head strongly convex; with crowded but rather small punc- 

 tures; inter-anteni)ary carina not continued beyond antennary 

 sockets. Antennae not very long, second joint slightly longer 

 than fourth, third almost as long as fourth and fifth combined, 

 fourth-tenth subquadrate, fourth and fifth short, but combined 

 considerably longer than sixth, sixth to tenth subequal, eleventh 

 distinctly longer. Prothorax with sides rounded in front, thence 

 almost parallel-sided to base; with dense and sharply-defined but 

 rather small punctures, becoming crowded on sides. Elytra 

 parallel-sided to near apex; base with crowded subasperate punc- 

 tures, becoming smaller and more sharply defined posteriorly; 

 striation well-defined. Hind coxte strongly and evenly narrowed 

 to sides, which are very short, greatest length slightly more than 

 that of second abdominal segment; basal joint of hind tarsi dis- 

 tinctly shorter than the rest combined, fourth slightly narrower 

 than third, and scarcely produced on lower surface. Length, 

 6 mm.
