444 Mr. G. J. Arrow on the 



position of rest, and tlie anterior legs are not closely fitted 

 together. The clothing consists of short setsB and not broad 

 scales. 



80 far as is known, the genus is confined to Australia. It 

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

 Soc. S. Austr. xxvii. 1903, p. 169) as " aberrant Cryptor- 

 rhopala^^ {C. australe, Hope, confertum, E,eitt., variabile, 

 lleitt., guadri/asciaium, Blackb., and terzonatum, Blackb.). 

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

 IMuseum, I believe to be the species later described as 

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



AntJirenocerus bicolor, sp. n. 



Niger, elytris pedibusque ferrugineis, corpore supra fulvo-pubes- 

 centi, setis 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 ; elytris crebre inmctatis, irregulariter quadrifasciatis, 

 fascia prima marginal!, apicibusque albo-setosis. 



Long. 2*5 mm. 



Hah. N.W. Australia: Adelaide R., Roebuck Bay {J.J. 

 Wn/ker). 



This has 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. 



Anthre7iocerus pulchellua, sp. n. 



Ferrugineus, setis decumbentibus brevibus flavis et albis inter- 

 mixtis variegatus, corpore subtus uigro, subtiliter 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. 



Hah. N.W. Australia: Baudin Point, Baudin I, 

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

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

 A. bicolor, 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 better-defined patches.
