dentatis. Long, (rostr. incl.) 2-t—3i 1. Lat. 1—1 1. 
Near M. Darwini, Blackb., but at once distinguisliable by inter aha the 
evidently longer basal two joints of the funiculus, the second of which is not at 
all shorter than the basal one. 
Idracowra, on Dodoncea viscosa. 
POLYPHRADES. 
P. tianidulus, Blackb. (68), Oodnabarrina, Tempe Downs, Storm Creek, 
Reedy Creek. 
P. satelles, Blackb. (8), Idracowra, Illamurta (on Cassia). 
LEPTOPS. 
Z. interior is ^ Blackb. (3), Alice Springs. 
Z. gravis, Blackb. (5), Crown Point, Idracowra, Illamurta (on Cassia). 
Z. contrarius, Blackb. (15), Idracowra, Tempe Downs, Alice Well, Charlotte 
Waters, Finke R., Ayers’ Rock, Crown Point (on Acacia frurnentaria). Some of the 
examples are so densely clothed with whitish scales that the black derm is scarcely 
visible. 
Z. sculptus, sp. nov., fern. (1). Ovalis \ minus nitidus; piceo-niger, pube 
grisea (hac in cavitatibus squamis minus conspicuis aurantiacis variegata) et setis

A large species, bearing much resemblance to several of its congeners, but 
distinguished from all of them (at any rate, from all the large species known to 
me) by its rostral scrobes being linear (as in Z. tribulus, Fab.) but quite straight. 
From Z. colossus, Pasc., raiicus, Blackb., biordinatus, Blackb., and planicollis.
