a wide median black fascia occupying almost one-third of 

 their surface, and complete from side to side. 



Var. 2. Two females from New South Wales (National 

 Park) have the antennae (except parts of the three basal 

 joints) deep black; one of them has the hind femora infuscate 

 towards the apex, but on the other they are entirely pale. 



Xylophilus pectinicornis, Champ. 



The female of this species differs from the male in being 

 slightly larger, the eyes smaller and not so close together, and 

 the antennal joints (after the third) very different; the third 

 is slightly shorter than the fourth and fifth combined, the 

 fourth to tenth are of almost even width but gradually decrease 

 in length, so that although the fourth is slightly longer than 

 wide, the tenth is slightly transverse, the eleventh is dilated 

 and almost as long as the ninth ai d tenth combined. 

 Several specimens were beaten from "Blackwood" (Acacia 

 melanoxylon). 



Xylophilus octomaculatus, Champ. 



Only the female of this species was known to Champion. 

 There are two specimens (sexes) in the Museum from Cairns 

 and Mount Tambourine, and a male in my own collection 

 from Wollongong. On the male the antennae are rather long, 

 with the second joint small, third-tenth subcylindrical and 

 equal, eleventh almost as long as eighth-tenth combined, sub- 

 cylindrical on basal half, then irregular towards and pointed at 

 apex; the legs are rather long, front trochanters lightly spinose, 

 hind femora stout; hind tibiae with apical half stouter than 

 basal half, but neither dilated to nor notched at apex. The 

 female differs in having smaller eyes, less close together 

 (although fairly close), antennae distinctly shorter, with the 

 eleventh joint considerably smaller and thicker in proportion, 

 abdomen more convex, legs shorter, front trochanters 

 unarmed, and hind femora thinner. The species is structurally 

 fairly close to abnormis, but the markings and antennae are 

 very different. On one specimen the prothorax is almost 

 entirely dark, on the others it is mostly of a dingy red ; on 

 one male there are four flavous spots on each elytron : one 

 on the shoulder, a smaller one near the suture at the basal 

 third, a larger one at the middle, and a still larger subapical 

 one; the latter with its fellow on the other elytron forming 

 a bisinuate fascia. On a second male the first sutural spot is 

 enlarged and continued to the base, and the subapical one is 

 split up into two. On a female there are but three spots on 

 each elytron : one on the shoulder, the medio-sutural one, 

 and the apical one, the latter being considerably enlarged.
