238 AUSTRALIAN PSELAPHIDJS, 



the frontal one is trapezoidal and a little convex, bounded behind 

 by a transverse groove and bearing two strong and short brushes 

 of yellow hairs; the posterior part is much raised all round, but 

 entirely hollowed, the raised sides ending abruptly and horn-like 

 on each side, in front of the eyes; the head is punctate except at 

 the bottom of the cavity; there are few scattered punctures on 

 the body; the maxillary palpi are long, the basal club of the 

 fourth joint is thick, briefly ovate and evidently shorter than the 

 apical subulate part, which is very slender; the antennal joints 

 3-5 are about twice longer than broad, 6-7 quadrate, 8 nearly 

 transverse, 9 obconic, not longer than broad, and 10 transverse. 



The above description is drawn up from two typical specimens 

 of porcellus, Schfs. If comiger, King, should not agree with this 

 description it must be considered as a different species. 



Clyde River, N.S.W.

 Schfs., loc. cit. p. 287. 



The body is shining, smooth, with very scattered but distinct 

 punctures; the head is rather strongly and densely punctate. 



£. Head nearly bipartite, the posterior part strongly punctate, 

 -raised, square, very abruptly truncate in front and ciliate, the 

 frontal part very much lower, convex, smooth, obsoletely sulcate 

 longitudinally in the middle. Maxillary palpi long, the basal 

 club of the fourth joint nearly fusiform and as long as the apical 

 subulate part. The antennal joints 3-6 a little longer than broad, 

 the 5th the longest, 7 square, 8 a little transverse, 9 subhexagonal, 

 a trifle longer than broad, 10 trapezoid, hardly transverse. 



£. Head much less punctate, simple, vertex convex, two strung 

 foveje in front of the eyes, frontal tubercle rounded on each side 

 and obsoletely divided into two; joints of the antennae shorter, 

 6-7 square, 8 transverse, 9-10 trapezoid and a little transverse.
