• 



pronotum are shallow but very distinct from some directions, 

 but the others are invisible from most. There is a short 

 shining process protruding from the abdomen, but as it has 

 two hair-like apical appendages I presume the type is a female. 



Xylophilus acaciae, n. sp. 



Piceous-brown ; head and abdomen sometimes blackish, 

 basal joints of antennae, palpi, and legs rather obscurely 

 flavous. Closely covered with extremely short, ashen pubes- 

 cence, becoming white on parts of under-surface. 



Head transverse ; with minute, concealed punctures. 

 Eyes large, prominent, lightly notched and not very close 

 together. Antennae moderately long, second joint small and 

 subglobular, eleventh wider than tenth, and almost as long 

 as ninth and tenth combined. Prothorax rather small, very 

 little wider than long ; punctures more or less concealed ; with 

 three conspicuous impressions : two suboblique ones separated 

 by a narrow line at base, and a longitudinal one in middle; a 

 feeble impression on each side of base. Elytra much wider 

 than prothorax, parallel-sided to near apex, with a feeble 

 impression on each side close to a very feeble subscutellar 

 swelling; punctures fairly distinct on basal half, but feeble 

 elsewhere. Legs rather long and thin; hind tibiae very little 

 wider at apex than near same. Length lf-2 mm. 



9 • Differs in having smaller and more widely-separated 

 •eyes, shorter antennae, prothorax rather more transverse, 

 abdomen less convex, and legs shorter.

A small dingy species with the pubescence so extremely 

 fine and close together that the upper-surface appears to have 

 a kind of "bloom" (present but to a less extent on the under- 

 surface). In general appearance it is fairly close to incon- 

 spicuus, but the punctures are very much smaller, and there 

 are many other differences. From most directions the parts 

 adjacent to the three larger prothoracic depressions appear 

 to form a conspicuous Y. The distance between the eyes of 

 the male at their closest is about equal to the length of the 

 two basal joints of antennae. The antennae are occasionally 

 entirely pale, but usually have the basal joints paler than the 

 others, the sterna are occasionally as dark as the abdomen, 

 the hind femora are sometimes lightly infuscated. One 

 specimen from Mole Creek, three from Wollongong, and the
