558 NEW SPECIES OF AUSTRALIAN COLEOPTERA, xiii., 



tenth, but shorter than ninth and tenth combined. Prothorax 

 rather small and slightly transverse, with a shallow, twice inter- 

 rupted impression across middle, and with four impressions at 

 base, of which the two median ones are oblique, larger and more 

 distinct than the others, and almost touch. Elytra comparatively 

 large, much wider than prothorax, sides feebly dilated to beyond 

 the middle, with a feeble swelling on each side of scutellum, and 

 a depression behind each swelling; with dense and sharply de- 

 fined punctures on basal half, becoming very small posteriorly. 

 Lpys long and thin; hind- tibiae thin throughout. Length, 1 J-Hmm. 



Hab.—^K^N. : Jenolan (J. C. Wiburd), Wollongong (A. M. 

 Lea). 



Readily distinguished from all the other, small, dingy species 

 of the genus, by the two, conspicuous, abdominal patches ; 

 although these are probably sexual (and masculine), they are 

 slightly elevated, and have denser clothing than elsewhere. The 

 elytra are distinctly paler than the prothorax, and the latter is 

 somewhat paler than the head; the basal joints of the antennae 

 are somewhat paler than the others. On one specimen, each 

 segment of the abdomen is flattened in the middle; on another, 

 they are similarly flattened, but the apical segment has a con- 

 spicuous depression on each side of the middle; probably, how- 

 ever, the flattening was due to the specimens being mounted 

 when the abdomen was in a soft condition. 



Xylophilus convexiceps, n.sp. 



(J. Blackish; palpi, tarsi, and coxee obscurely paler. Moder- 

 ately clothed with very short, depressed, ashen pubescence; the 

 elytra, in addition, with a few, fine, upright hairs. 



Head of moderate size and rather strongly convex, narrowed 

 V)ehind eyes and at base, with a distinct (but normally concealed) 

 neck, median line vaguely traceable, semicircularly depressed in 

 front; with dense and sharply defined, but rather small punc- 

 tures. Eyes rather small, lateral, very prominent, entire, rather 

 distant from base. Antennae long and thin, each inserted in 

 front of a slight ridge placed obliquely inwards from the eye,
