548 NEAV SPECIES OF AUSTRALIAN COLEOPTERA, xiil., 



>7rt6. — Queensland : Dalby (Mrs. F. H. Hobler). Unique. 

 On the type, the liead is darker than the prothorax, and the 

 latter has the base (and the apex more narrowly) somewhat 

 flavous. The dark markings on the elytra are so disposed that 

 the flavous parts are isolated as follows : a large patch on each 

 shoulder, almost touching the suture, and on the side extending 

 to the basal fourth (in some lights, a feebly infuscated line ap- 

 pears to divide each humeral spot into two); a large, trilobed, 

 median patch, of wliich tlie median lobe is advanced along the 

 suture to about the ])asal fourth; and a bisinuate fascia near the 

 apex, but slightly interrupted by the suture: the three apical 

 segments of the abdomen are paler than the others. The antennae 

 are very peculiar; the joints actually decrease in size from the 

 fourth to the ninth; the tenth varies in appearance with the 

 point of view; from one direction, it appears to be thinner than 

 the ninth, and almost as long as the ninth and tenth combined; 

 it is joined to the ninth near its base, which is produced to one 

 side as a rather acute point; the eleventh is much wider than 

 long, and very acute at its inner apex (in general appearance, 

 the eleventh joint is curiously suggestive of a small, geological 

 pick-head, or of the apical joint of a scorpion's tail): from some 

 directions, however, the joints of the antennse appear to be of 

 even width from the third to the tip, with the tenth joint con- 

 spicuously longer than the eleventh, and the latter very similar 

 to the ninth. 



Xylophilus intricatus, n.sp. 



^. Flavous ; prothorax and elytra with conspicuous, dark 

 broNvn markings; head, sterna, and part of abdomen blackish, 

 antennae reddish- flavous, but apical parts much darker, four 

 hind-femora deeply infuscated towards base. (clothed with 

 short, whitish pubescence, inconspicuous on prothorax and 

 elytra, dense on head and undersurface. 



Head with eyes large, deeply notched, and almost meeting at 

 tlieir nearest point. Antenna? moderately long, some of the 

 joints curiously formed. Prothorax moderately transverse; 

 punctures irregular and partially concealed; with a conspicuous, 

 transverse impression on each side in front, and another ^divided
