its somewhat narrower form and elongate antennae; the female is distinguished 

 hy the elytral mucronation. 



This species is not uncommon at Blaekheath, on the Blue Mountains. 



The above description has been drawn up from specimens in my own collec- 

 tion. On the name label in the Macleay Museum are two females, measuring 21 

 X 7.5 mm., and 19 X 7 mm.; the elytral tubercles number 9, 9, 5, and 8^10, 

 8 — 9, 4 — 5 on the two specimens. 



.Some years ago I examined a specimen in the Brussels Museum collection 

 whieh was labelled as being the type of ^-1. echinatus Boisd.* The whole question 

 of the use of the name echinatus is discussed elsewhere in this paper (see p. 37.) 



ACANTHOLOPHUS SPINIPER Macl. 



Macleay, Trans. Ent. Soc. N.g.w., i., 1865, p. 284; .1. homttii, Macl., Id. p. 285. 



<S. Allied to A. marsham i Kivhy. but with the posterior tai-si longer. Black; 

 thinly clothed with minute squames, brownish along suture, greyish wliite on the 

 inner side of the second and third rows of elytral tubercles. 



Head concave in front, with distinct intercristal ridge; supraorbital crests 

 stout, arising from a broad base, the antei'ior ramus strongly convex anteriorly, 

 apex upwardly projecting, rather blunt, posterior ramus longer, pointing up- 

 wards and slightly backwards. Rostrum with lateral margins strongly raised 

 and angulate in the middle. Antennae with flret two joints of funicle subequal, 

 club not pedunculate. Prothorax arranged as in A. marsham,i, the submedian 

 tubercles larger, rounded or obtusely conical, the penultimate convergent, ridge- 

 like; lateral tubercles as in A. marshami. Elytra rather strongly convex; punc- 

 tures small, but evident and regular, granules not traceable except at base of 

 suture; tubercles mostly conical and spinifonn; first row with 7, the basal ones 

 obtusely, the othere acutely conical and larger, ending on edge of declivity, 

 second row with 8, all acutely conical, the apical tubercles larger and spiniform, 

 extending half-way down declivity; humeral tubercle about one-half the size of 

 first of third row; third row with 4 — 5 acute tubercles. Ventral surface nitid, 

 with small and obsolescent punctures, somewhat larger on apical segment, not 

 confluent except at extreme apex. Leg's simple, posterior tarsi with basal seg- 

 ments noticeably longer and more slender than in A. marshami. 



9. (A. howittii Macl.) — Similar but broader; supraorbital crests with the two 

 rami hardly separated ; elytra with e\'idont rows of granules between the tubercles, 

 the latter slightly smaller than in c?, 6, 7, 3 — 4, and two small tubercles are pre- 

 sent on second interstice; apex of elytra rather feebly mucronate. Venter con- 

 vex, punctures as in male. Dimensions: c?. 16 x 5 unn. ; ?. 18 x 7.5 mm. 



Hab. — Victoria: Bendigo, Mordialloc. 



There are 2 males on the name label of A. spinlfer in the Macleay Museum, 

 and two females on that of A. Iiowittii. A series from Bendigo, for which I am 

 indebted to Mr. J. E. Dixon, and a series from Mordialloc in the National 

 Museum agree with the Macleay Museum specimens, with the exception that the 

 tubercles are somewhat fewer in number (5 — 6, 6, 3 — 4) ; the Mordialloc speci- 

 mens are more densely covered with brownish clothing; in some cases the tubercles 

 alone are uncovered.
