9 • Differs in having the abdomen not notched and its tip obscurely reddish. 



Hah. — New South Wales: Hay (A. M. Lea); Victoria: Murtoa. 



A large, shining, black species, with simple mandibles, readily distinguished 

 from all others known to me (except P. marginellus, which has tips of the 

 elytra red, and very different mandbles) by an even row of four large setif erous 

 punctures across the front of the head; between these and the basal third (where 

 they are crowded) the punctures are very sparse and subseriately arranged; 

 on close examination minute punctures may be seen scattered about. 



Pinophilus apterus, n. sp. Fig. 6. 



9 • Pale castaneous, abdomen darker, antennae, palpi, and legs paler. 

 Rather densely clothed with dark pubescence, sparser on head than elsewhere, 

 and with long hairs scattered about, becoming numerous on apex of abdomen. 



Head strongly transverse, hind - angles strongly rounded ; with fairly large 

 and sharply-defined punctures, crowded about base, forming an irregular double 

 semicircle between antennary tubercles, and an irregular row in front ; with 

 minute ones scattered about. Mandibles long, thin, curved, and with a small 

 acute tooth near base. Antennae rather long and thin, all of the joints longer 

 than wide, and evenly decreasing in length after the third. Prothorax slightly 

 transverse, hind angles strongly rounded, the front ones moderately so, sides 

 gently rounded, apex considerably wider than base and just perceptibly wider 

 than head ; with crowded punctures, distinctly smaller than on head, the inter- 

 spaces with very minute ones ; median line very feeble, but traceable almost 

 throughout. Elytra transversely oblong, narrower and much shorter than pro- 

 thorax ; punctures slightly larger and more crowded than on prothorax. 

 Abdomen with crowded punctures on both surfaces. Front femora very stout, 

 Vv'ith a feeble, abruptly-terminated ridge; four basal joints of front tarsi forming 

 a strongly-dilated pad. Length, 13 mm. 



Hab. — New South Wales: Gosford (H. W. Cox). Unique. 



An unusually robust, apterous species with transverse elytra. The jaws, 

 when clenched, appear to be simple, but on relaxation they are seen to have a 

 minute acute tooth near the basal swelling, much as on P. mastersi, which is 

 a much narrower species, with very different abdomen. Its nearest ally appears 

 to be P. australis, but the head has a shorter space between the eyes and neck, 

 the tooth on each mandible is slightly more advanced and acute, the prothorax 

 is distinctly transverse, and the punctures are slightly less dense. The type is 

 almost certainly immature, but as it represents a very distinct species it was 

 considered desirable to name it. 



Pinophilus semiopacus, n. sp. Fig. 7. 



9 ■ Black ; antennae, palpi, and legs flavous, abdomen iridescent, its tip 

 and the mandibles reddish; with rather dense black pubescence, and with 

 numerous hairs scattered about. 



Head strongly transverse, base obtusely bilobed ; with crowded punctures 

 of several sorts. Eyes unusually large. Mandibles long, acute, and each armed 

 with a large, acutely bicuspidate median tooth. Antennae very thin, passing 

 base of prothorax, all the joints longer than wide, but decreasing in length after 

 the third. Prothorax about as long as apical width, hind angles strongly 

 rounded, front ones almost square ; with crowded punctures ; median line 

 feeble, but traceable almost throughout. Elytra slightly wider than prothorax 

 and about once and one-third as long, sides gently rounded, the angles rather 

 strongly so ; with crowded punctures, slightly larger than on prothorax, and 

 many transversely or obliquely confluent. Abdomen with punctures scarcely 

 smaller but somewhat shallower than on elytra, more crowded and confluent
