and rather small punctures on disc (but almost absent along 

 middle), becoming transverse and larger towards apex (where 

 they are crowded and transversely or obliquely confluent), and 

 more numerous on sides. Elytra with rather large shallow 

 punctures, in more or less regular rows, but becoming denser 

 and irregular on sides and apex, striae shallow. Pygidhtm 

 with rather crowded punctures. Basal joint of four hind 

 tarsi dilated externally, and with several deep notches. 

 Length, 13-14 mm. 



Hah. — Western Australia: Beverley (F. H. du Boulay). 

 Type, I. 2262. 



The strongly bilobed clypeus and conspicuous geminate 

 tubercles of head readily distinguish this from all previously 

 described species of the genus. The claws of the front tarsi 

 are not distorted on any of the three specimens before me, but 

 the curious notches on the tarsi are probably indicative that 

 they are males.

Some males from the Alligator River (Northern Territory) 

 agree so closely in sculpture with typical specimens of Jbhis 

 species, that I cannot regard them as representing more than 

 a variety; they differ, however, in having the upper parts 

 entirely black, the pygidium and propygidium blackish, and 

 a greater portion of the legs infuscated.

 Merimna atrata, L. and G. 

 Numerous specimens of this species were seen on the 

 hottest days, basking on the extremely hot brick wails of the 

 baking ovens at Ooldea.
