Hab. — Northern Queensland (Blackburn's collection). 

 Type, I. 6174. 



Allied to inidatus, but antennae longer and otherwise 

 different, elytra with infuscate markings near tip and scutel- 

 lum, and the median fascia of all four specimens before me 

 not the same as on all the thirteen of undatus. There is a 

 conspicuous black median fascia on the elytra, oblique on 

 each side, touching the suture (where it is narrowest) almost 

 at the exact middle, and at the sides (where it is considerably 

 dilated) nearer the base; on two specimens it is continued as 

 a lateral infuscation almost to the base; the suture is narrowly 

 infuscated ; the infuscation semicircularly or subtriangularly 

 dilated at the base (so as to include the scutellum), and 

 slightly dilated (so as to form a small sutural spot) near the 

 apex. The distance between the eyes of the female is about 

 equal to the length of the first antennal joint, in the male 

 it is much less. The pronotum has three very vague depres- 

 sions at the base, the median one being all that is left of a 

 median line, but on one specimen there is another remnant 

 of it at the apex. 



Xylophilus flavicollis, n. sp. 



<3 . Flavous ; elytra, mesosternum, metasternum, and 

 abdomen blackish-brown ; antennae (two or three basal joints 

 excepted) deeply infuscated. Clothed with extremely short, 

 indistinct pubescence. 



Head with numerous minute punctures. Eyes large and 

 prominent, fairly close together at their nearest point, lightly 

 notched in front. Antennae rather long and thin, second 

 joint slightly smaller than third, eleventh subovate, about 

 as long as ninth and tenth combined. Prothorax rather small 

 and lightly transverse, with a feeble transverse median 

 impression, with two small but distinct subcontiguous impres- 

 sions at base ; with fairly dense, partially-concealed punctures. 

 Elytra much wider than prothorax, parallel-sided to near 

 apex, with a vague swelling on each side of scutellum ; punc- 

 tures dense and sharply denned but not very large about 

 base, becoming much smaller posteriorly. Legs moderately 

 long; hind tibiae conspicuously dilated to and notched at 

 apex. Length, lf-2 mm. 



9 • Differs in having eyes less prominent and not so 

 close together, antennae shorter, with second joint slightly 

 stouter than third (but not longer), prothorax more trans- 

 verse, elytra somewhat wider, abdomen more convex, and 

 legs somewhat shorter with hind tibiae not quite so wide 

 at apex.
