position of rest, and tlie anterior log3 are not closoly fitted 

 together. The clotliing consists of short setie and not broad 

 scales. 



So far as is known, tlie genus is confined to Australia. It 

 includes the five species grouped by Bhiekburn (Trans. Roy. 

 Soc. S. Austr. xxvii. 1903, p. 169) as " aberrant Cri/ptor- 

 rhopala^^ {(L australe, Hope, confertum, Reitt., variahile^ 

 Reitt., guadri/asci'afuin, Bhickb., and terzoualum, Blackb.). 

 The first, of which I have examined the type in the Oxford 

 ^Museum, 1 believe to be the species later described as 

 Trogoderma riguum, Er. Two other species are added here : — 



Antlirenocerus bicolor, sp. n. 



Niger, elytris pedilmsque ferrugineis, corpora supra fulvo-pubes- 

 centi, sctis longioribus albidis variegato, subtus minute sat crebre 

 albo-vestito ; ovatus, pronoto brevi, subnitido, postice fortiter 

 lobato, lobo dense, marginibus anticis et lateralibus minus dense 

 albo-setosis ; elyrris crebre jmuctatis, irregulariter quadrifasciatis, 

 fascia prima marginali, apicibusque albo-setosis. 



Long. 2*5 mm.

Walker). 



This lias a close similarity to A. ausfralis, Hope, but is 

 easily distinguished by its reddish elytra, in addition to which 

 the bands of white hairs are more irregular. 



Anthrenocerus pulchelluSf sp. n. 



Ferrugineus, setis decumbentibus brevibus flavis et albis inter- 

 mixtis variegatus, corjwre subtus nigro, subtihter sat crebre 

 albo-vestito ; anguste ovatus, convexus, prothorace antrorsum 

 valde angustato, postice fortiter lobato, lobo partibusque anticis 

 et lateralibus griseo-setosis ; elytris irregulariter trifasciatis, fascia 

 antice ad suturam late interrupta, ad basin producta, apicibus 

 etiam setosis. 



Long. 2 mm.

This, as well as the last species, was taken by Commander 

 J. J. Walker. It is a smaller and narrower insect than 

 A. bicolur, and the clothing of the upper surface consists of 

 shorter and more close-lying, rather scaly hairs, yellow and 

 white mixed, disposed as in A, bicolor, but in rather larger 

 and bettei-defincd patches.
