larger eyes, antennae longer and thinner, and in the prothoracic puncUn-es ; on 

 that species the punctures on the sides are irregular up to those on each side of 

 the median line; on the present species (and to a less extent on L. piinctipcnne) 

 the punctures on the sides arc also irregular but not up to the median line, so 

 that from certain directions there appear to be three shining lines separated by 

 rows of punctures. 



Lathrobium angustulum, n. sp. 



9- Of a dingy piceous-brown ; head almost black, antennae, palpi, and 

 legs flavous. With fairly numerous dark setae, the abdomen rather densely 

 pubescent, the elytra more sparsely so. 



Head rather elongate ; with numerous sharply-defined but not very large 

 punctures, becoming crowded on hind angles. Mandibles strong, each with a 

 large median tooth, and some smaller ones towards base. Antennae with first 

 joint as long as second and third combined, third distinctly longer than second, 

 and almost as long as fourth and fifth combined, the following ones to tenth 

 gradually becoming subglobular. Prothorax distinctly longer than wide, apex 

 slightly narrower than head and not much wider than base, sides gently incurved 

 to middle ; with rather dense sharply-defined punctures, but leaving a rather 

 narrow, shining, median line. Elytra distinctly longer than prothorax and 

 slightly wider than its widest part, parallel-sided ; punctures somewhat smaller 

 and less sharply defined than those on prothorax. Front femora stout, \vith 

 a small but acute tooth ; front tibiae rather stout, feebly notched near middle ; 

 four basal joints of front tarsi dilated to form a suboval pad ; basal joints of 

 hind tarsi short. Length, 6 mm. 



Hah. — New South Wales: Tamworth (A. M. Lea). Unique. 



An unusually narrow species, allied to L. adclaidae, but even thinner, darker, 

 antennae longer, and elytral punctures slightly dififerent. The prothorax is not 

 as dark as the elytra, but is not conspicuously reddish, the two apical segments 

 of abdomen, and the tip of the preceding one, are paler that the other segments. 

 The main portion of the head is slightly longer than wide, but from tip of the 

 extended mandibles to the base of the neck the head is almost twice as long as 

 wide. The elytral punctures are not regularly disposed, but from some directions 

 they appear in places to be feebly seriate in arrangement. The abdomen of the 

 type has most of the segments with the membranous part of each showing, 

 so that it appears to be in alternating pale and dark bands, but the pale ones 

 would be concealed on most specimens. 



Lathrobium mediopallidum, n. sp. 



S • Pale castaneous ; antennae, palpi, and legs paler, head and most of 

 abdomen infuscated. Abdomen with dense and very short pubescence. 



Head subquadrate between mandibles and neck ; with numerous sharply- 

 defined but not very large punctures. Mandibles stout and strongly dentate. 

 Antennae with basal joint as long as second and third combined, third slightly 

 longer than second and conspicuously longer than fourth. Prothorax distinctly 

 longer than wide, widest in front, where the width is slightly less than that of 

 liead. sides gently incurved to middle ; punctures as on head, except that they 

 are absent from a narrow, shining median line. Elytra parallel-sided, distinctly 

 wider and much longer than prothorax ; and with somewhat smaller and denser 

 punctures. Apparent fifth segment of abdomen depressed in middle of apex on 

 under-surface, the sixth triangularly notched there. Front femora stout and 

 with a rather small tooth; front tibiae slightly notched before middle, apical 

 portion stout ; four basal joints of front tarsi dilated to form a suboval pad, 

 basal joints of hind tarsi small. Length, 4.25 mm.
