at Mt. Victoria (January, 1920). Two of the series (c?— Mt. Victoria, ?— Black- 

 heath) are much smaller than the others, measuring: c?. M X 5, S. 15 X 6.5 mm., 

 but do not present any other appreciable differences. 



I have carefully compared my series of A. spinifer Macl., and the above 

 \arieties, without being able to find any differences that can he regarded as of 

 specifie value. The various forms are, nevertheless, readily distinguished by 

 their general appearance. The number of tubercles on the elytra is too variable 

 to be used as a distinctive feature; the average size of the tubercles is smaller 

 in var. montanus than in the other forms. The clothing is variable, but var. 

 fuscovittatus is more distinctively clothed than the others. There are slight dif- 

 ferences also in the comparative lengths of the joints of the funicle ; in the types 

 the first two joints appear to be subequal, in other Victorian forms the second 

 joint is slightly longer than the first, and in the varieties fuscovittatus and mon- 

 tanus it is more decidedly so. while in var. hlandensis, the two joints are equal 

 but are longer than in the types. 



ACANTHOLOPHUS SORDIDUS, n.Sp. 



A small species allied to A. spinifer Macl., but with smaller, obtuse tubercles. 



(?. Moderately densely covered with obscure brownish clothing. 



Rostrum as in A. marshami, the external margins rather obtusely angulate. 

 Head with supraorbital crests broad at base, the free margin barely notched be- 

 tween the two rami, anterior border strongly convex, posterior ramus briefly 

 pointed and projecting backwards. Antennae as in A. spinifer. Prothorax 

 tuberculate as in A. marshami, the median tubercles slightly smaller, the two 

 anterior conjoined. "Elytra with a row of granules along suture, and another 

 less evident, along second interstice ; tubercles small, noduliform, only the posterior 

 ones distinctly conical ; first row^ with 7, the basal one elongate, the following 3 

 smaller, nodulifonn, the last 3 becoming progi'essively larger and more conical, 

 ending at edge of declivity; second row with 7, only the last 3 conical, extending 

 further down declivity; humeral tubei'cle moderately large, followed by third row 

 with 4 tubercles, the first the largest. Under surface setigero-punctate, the punc- 

 tures small, not confluent, except at apex, where they tend to become reticulate. 

 Legs simple. 



9. Larger and liroader. the elytra feebly granulate between the rows of 

 tubercles, the latter smaller than in the male, 7, 7, 4 in number in the three rows; 

 venter convex, setigero-punctate. Dimensions: c?. 14.5 x 5 mm.; 9. 16 X 6. ,5 mm. 



Hah. — Victoria: .Tamieson (T. G. Sloane). 



The species is founded on a pair received from Mr. T. G. Sloane. It is a 

 small dingy species without any salient characteristics. It is closely allied to A. 

 .spinifer, and might have been considered a variety, but the difference in the size 

 of the tubei-cles and to some extent the shape of the crests lead me to regard it 

 as worthy of specific rank. 



ACAXTHOLOPIIU.'? SUBTRIDEXT.VTUS, n.Sp. 



A moderately small species, without outstanding characteristics. 



d". Black; moderately densely clothed with brown depressed subpubeseence. 



Head deeply concave in front; intercristal ridge well marked; supraorbital 

 crests large, broad at base, the two rami conjoined for the gi'eater part, of their 

 length, anterior border convex, free margin with a distinct though not deep, 

 notch anteriorly between the rami, and with a shallower indentation posteriorly.
