PiNOPHILUS LATEBRICOLA, Blackb. 



Three specimens from Coburg (Victoria) possibly belong to this species, 

 but they dififer from typical ones in having the jaws about one-fourth longer 

 and less suddenly departing from the general curvature at the inner base. With 

 the jaws clenched the differences could not be noted, but when open they are 

 at once evident ; they are not sexual, as a male of each form has been compared. 



Pinophilus major, n. sp. Fig. 5. 



'^ • Black ; mouth parts, antennae, palpi, and tarsi reddish. Rather densely 

 clothed with short, subdepressed, ashen pubescence ; a few hairs on head and 

 numerous ones about apex of abdomen. 



Head strongly transverse; with crowded and not very large but sharply- 

 defined punctures, becoming sparser, but still fairly numerous in front of a 

 semicircular, shining line connecting the antennary tubercles. Mandibles long, 

 thin, curved, and simple. Antennae long and very thin. Prothorax scarcely 

 as long as the greatest width, hind angles strongly rounded off, front ones almost 

 square, apex truncated except for a slight incurvature towards each side ; with 

 crowded punctures, much as on base of head ; median line represented by a 

 feeble remnant near base. Elytra very little longer than prothorax and scarcely 

 as wide as its apex, very little longer than wide; punctures somewhat denser 

 and more angular than on prothorax, and in places partly transversely confluent. 

 Abdomen with crowded, suboblong punctures at base of most of the segments, 

 becoming smaller and less crowded posteriorly, apex of apparent sixth segment 

 triangularly notched on under-surface. Front femora very stout and obtusely 

 dentate, four basal joints of front tarsi forming a very wide pad. Length, 

 20-25 mm. 



Hab. — New South Wales: Darling River, in flood debris (R. Helms); 

 North-western Australia (Dr. A. M. Morgan). 



The largest species as yet recorded from Australia, from P. australis, the 

 next in size, the present species differs in having the mandibles quite simple, 

 the legs darker, elytra longer, and body winged. On close examination a few 

 minute punctures may be seen scattered amongst the larger ones on the front 

 part of the head. On the type two basal joints of the antennae are partly black, 

 the front tarsi are much paler than the others, the knees and tip of abdomen 

 are obscurely reddish. The specimen from North-western Australia has the 

 front legs entirely reddish, and the others with only part of the femora 

 infuscated. 



Pinophilus punctifrons, n. sp. 



d . Black; antennae (most of the joints partly infuscated), palpi and 

 tarsi more or less reddish. Rather densely clothed with dark pubescence, 

 sparser on head (parts of which are glabrous) than elsewhere; in addition with 

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



Head strongly transverse, hind angles moderately rounded off ; punctures 

 of moderate size, sharply defined and irregularly distributed. Mandibles long, 

 thin, curved, and simple. Antennae long and very thin, all the joints much 

 longer than wide. Prothorax about as long as the apical width, apex (except 

 for a feeble incurvature towards each side) truncate, sides gently rounded but 

 hind angles strongly rounded ; punctures much as on base of head ; median line 

 distinct only near base. Elytra about once and one-third the length of pro- 

 thorax and very little wider than its apex; punctures rather more crowded, 

 but scarcely larger. Abdomen with crowded angular, more or less confluent 

 punctures at the base of most segments, becoming smaller posteriorly on each, 

 apparent sixth segment triangularly notched at apex on under-surface. Legs 

 not very long; front femora very stout, with a ridge ending as an obtuse tooth; 

 front tarsi with four basal joints dilated to form a wide pad. Length, 19 mm.
