RELATED CAXE BEETLES AND THEIR ALLIES. 73 



the majority had just moulted to stage III ; by 15th January three had 

 recently pupated, and beetles emerged from these on 22nd January, 

 giving a pupal period of about seven days. Thus the entire life-cycle 

 was consunnnated in less than three months. Since it has now been 

 ascertained that this species completes its life-cycle in so short a time, 

 it might reasonably be supposed that there is more than one brood a 

 year; furthermore, Dynastids similar in appearance {Scmfuwpfrrus. 

 Fentodon, &c.) may possess analogous habits. 



The occurrence of larva? in isolated patches in canefields, instanced 

 by Dodd (91), may have some relation to the presence of manure in 

 the soil. 



PENTODON AUSTRALIS BLACKBURN. 



This is indeed a rare species in the Cairns district, and in the past 

 six years not a single specimen has been recorded. The larva remains 

 unknown to us. 



EOPHILEURUS DENTATUS BLACKBURN. 



Our collection contains two specimens, both caught at lights in 

 December; they somewhat resemble Semanoptcrus depressiusculus, but 

 are fully twice as large. 



PSEUDHOLOPHYLLA FURFURACEA BURMEISTER. 



Note bv J.FJ. — During the preparation of this paper I tried 

 repeatedly to secure specimens of the Isis cane-beetles for iclentitication. 

 Even an appeal to ]\Ir. Tryon. who had carried out extensive investiga- 

 tions in that district, brought no results. Therefore, after the termination 

 of my engagement I visited Childers, in June, and managed to secure 

 specimens (l)otli grubs and beetles) of the principal culprit. Through 

 the kindness of the South Australian Museum, the species has been 

 tletermined, as above, by Mr. A. j\I. Lea, their entomologist. His 

 references are as follows: — ■ 



" HoIopJiijlhi furfiiroc( a Burmeister, Ilandbuch der Entomoloo-ie. 4 

 (2), p. 426 (i855j, Neu Holland." 



"Blackburn, Transactions of the Royal Society of South Australia, 

 1011, p. 181-184, comments at length on the species, and on page 196 

 l)roposed the new genus PseudJwlupJujIla for the species he .supposed 

 it to be. The specimen he had before him we now have, also anotlun- of 

 the same species from Bowen. Until Blackburn's identitication can be 

 proved to be erroneous by comparison with the type (if this is still 

 extant), it must be accepted as correct, and you would be justified in 

 dealing with the species under the name Pseudholophylla furfKnirca 

 Burm."
