penultimate joint entire. Head and prothorax (including under- 

 surface) reddish-brown; pronotum with wide testaceous lateral 

 margins; elytra of a light testaceous colour, with a postmedian 

 irregular black fascia (black area occupying about one-third of 

 elytra, anchor-shaped, reaching forward to the scute! him along 

 first interstice and extending forward considerably on each 

 elytron on interstices 6-8); metasternum testaceous; abdomen 

 somewhat infuscate; femora pale testaceous, tibiae, tarsi, and 

 antennae ferruginous. 



Head (1-4 mm. across eyes), finely punctate; front depressed; 

 vertex declivous to occiput (especially near eyes): a slightly 

 raised longitudinal carina beside each eye; eyes large, hemi- 

 spherical: orbits laminate, truncate behind eyes. Prothorax 

 transverse (1 "15 X 1*63 mm.): disc rather convex, rugulose, min- 

 utely punctate under a lens; margins wide, flat, explanate at 

 basal angles; sides rounded off from just behind anterior marginal 

 seta to apex, very slightly obliquely narrowed to base: apex 

 truncate-emarginate; base much wider than apex, basal angles 

 subrectangular (not prominent or acute, summit obtuse). 

 Elytra subquadrate with angles rounded (4 ,x 2*7 mm.), much 

 wider at base than prothorax; base emarginate behind peduncle, 

 widely rounded on each side; sides lightly rounded; stria^ simple, 

 strongly impressed, seriate punctures of ninth large, not widely 

 interrupted in middle. Anterior tarsi in ^ squamulose beneath 

 four, intermediate beneath first two joints Length, 6*3-7 :

Hab. — Queensland : Kuranda (Dodd), Cooktown District 

 (Sloane). Type in Coll. Sloane. The type-specimen occurred to 

 me under loose bark on the trunk of a river-gumtree {Eucalyptus 

 sp.) on the banks of the upper Normanby River at King's Plains 

 cattle-station in July, 1916. 



Differs conspicuously from its nearest allies (e.g., Ph. nigricollis 

 MacL, and Ph. farino' Blackb.) by not having the basal testa- 

 ceous area of the elytra divided from the sides by a black stripe 

 along sixth and seventh interstices. Though its elytral pattern 

 is peculiar to itself, its general appearance resembles that of Ph. 

 ser7iiviUatu.s Mac!.: but Ph. semivittatus is isolated in the genus
