46 Mr. G. C. Champion on 



A specimen ($?) from W. Australia (found by Du 

 Boulay) in the British Museum, ex coll. Fry, agrees with 

 Lea's description of X. eucalypti : it has the antennae 

 (the basal joint excepted) and prothorax rufo-testaceous, 

 the former rather short and slender. Two others, from the 

 same source, with the antennae much longer, stouter, and 

 a little darker, and the prothorax piceous or black, seem 

 to be males of the same species. They all have the 

 elytra flattened, very minutely punctate, and with an 

 unusually deep post-basal depression; and the deep basal 

 depression on the prothorax divided in the middle by a 

 short carina. The types were beaten from the boughs 

 of young gum trees. 



54. Xylophilus morulus. 



Xylophilus morulus, Champ., Trans. Ent. Soc. Lond. 1895, 

 p. 250 (#) (June 1st). 



Lea in 1897 sunk X. morulus, from Tasmania, as a 

 synonym of his Syzetoninus impressicollis, from Galston, 

 N.S.W. [Proc. Linn. Soc. N.S.W. (2) ix, p. 624, March 28th, 

 1895], the type in each case being a <§. This synonymy 

 is incorrect, neither the Tasmanian <$, nor a $ from Tas- 

 mania doubtfully referred to the same species, agreeing 

 with his description of S. impressicollis. X. morulus, <$, 

 is an elongate, flattened insect, with long, parallel-sided 

 elytra, the punctuation of which is uniformly fine and 

 dense throughout, and long antennae. 



55. Xylophilus darwinensis, n. sp. 



$. Oblong, depressed, opaque, the elytra shining, finely pubes- 

 cent; testaceous, the head slightly infuscate, the eyes black, the 

 elytra with a narrow, faint, brown subniedian fascia ; closely, 

 minutely, the elytra more distinctly, punctate. Head short, very 

 little wider than the prothorax; eyes convex, distant, occupying 

 nearly the whole of the sides of the head, feebly emarginate ; antennae 

 short, slender, joints 1 and 2 rather stout, 3 not longer than 2, 

 3-10 gradually becoming wider, 8-10 transverse, 11 acuminate- 

 ovate, rather stout. Prothorax strongly transverse, narrowed in 

 front, shallowly bifoveate at the base. Elytra oblong, wider than 

 the head, somewhat rounded at the sides, transversely depressed 

 below the base. Legs short, slender, the posterior femora slightly 

 thickened.
