Australian and Tasmanian Cryptocephalides. 449 



species of the subfamily ; and I have no doubt but that 

 in the hands of some others it would have been considered 

 as the type of a new genus. 



Cadmus T-niger, n. sp. 



2 . Elongate-oblong, moderately shining. Reddish-testaceons, 

 basal half of head and two oblique lines in front, extreme base of 

 prothorax, scutellum (except in middle), base and suture of elytra, 

 pygidium, greater portion of under-surface and femora (except at 

 base and apex), black — with or without a greenish gloss ; tarsi, 

 apex of tibite and antennse (except the second — fifth joints) more 

 or less infuscate, margins of prothorax pallid. Pygidium and under- 

 surface with silvery pubescence. 



Head densely and coarsely punctate, punctures fre({uently longi- 

 tudinally confluent. Antennse long, thin, and passing apex of 

 body, second joint less than one-third the length' of third, third 

 distinctly longer than fifth, sixth — tenth gradually decreasing in 

 length. Prothorax not twice as wide as long ; coarsely punctate, 

 the punctures rougher at sides than on disc ; margins rather wide, 

 incurved at middle, oblique impressions fairly deep but indistinct. 

 Scutellum subtriangidar, apex truncate, base rather deeply notched ; 

 impunctate. Elytra oblong, narrowest near base, shoulders thickened 

 and smooth, subhumeral lobes rather small ; densely and coarsely 

 punctate, punctures seriate in arrangement, with convex interstices 

 posteriorly ; basal half transversely rugose. Pycjidinm densely and 

 rather finely punctate. Under-surface rather densely transversely 

 strigose. Prosternum obtusely rounded at hind apex, and feebly 

 ridged along middle. Fourth segment of abdomen continuous but 

 encroached upon by fovea, this large deep and rather more densely 

 clothed than usual, and with scarcely traceable lateral extensions. 



Length 7^-9 mm. 



Hal. N. S. Wales .- Mt. Kosciusko ( W. E. Raymond 

 and R. Helms). 



The dark part of the elytra resembles the letter T, 

 from the base the dark marking is continued on to the 

 humeral callosities, in one specimen stopping there, in 

 a second continued (except for a break in its middle) 

 to beyond the middle (but not touching the sides), 



A rather small female specimen, which I can only regard 

 as a variety, differs in having the punctures much coarser, 

 with the antenna? stouter and shorter than the body. 

 Its head (except for an obscure space behind each eye), 

 the sides and apex of prothorax, the scutellum, the outer .
