Australian and Tasmanian Crypiocqihalidcs. 453 



Cadmus apicirufus, n. sp. 

 (Plate XXIV, fig. 105.) 



^ . Oblong, shining. Head (base blackish), pruthorax (the sides 

 paler), an inner spot at the apex of each elytron and the coxee 

 reddish ; middle of pro- and meso- and flanks of metasternuni, 

 abdomen (the second — fifth segments infuscate in middle), pygidium 

 (a small infuscate spot on each side) and subhumeral lobes pale 

 tlavous ; elsewhere black or blackish. 



Head densely and coarsely punctate. Antenna3 rather stout, not 

 extending to apex, second joint slightly shorter than third or fourth, 

 sixth distinctly longer than first, seventh— tenth gradually decreasing 

 in length. Prothorax about once and one-half as wide as long ; 

 disc gibbous ; margins entire and rather narrow ; densely punctate, 

 the punctures rather coarse at sides ; oblique impressions feeble. 

 Hcutelbim subquadrate, base indistinctly notched and feebly punctate. 

 Elytra suboblong, widest across shoulders (which are thickened and 

 impunctate), subhumeral lobes large ; densely and coarsely punctate, 

 the punctures almost as dense and large at apex as at base. Pygidium 

 densely and rather coarsely punctate. Under-surface irregularly 

 punctate, the punctures larger and sparser on metasternuni and 

 intercoxal process of prosternum than elsewhere, the latter in front 

 produced backwards like a lip, the hind apex very obtusely rounded. 

 Apex of abdominal segments (except the first) semicircular, the fifth 

 encroached upon by the pygidium. 



Length 3f mm. 



5 . Difters in being larger, with shorter antennae, and of which 

 the first joint is distinctly the longest; eyes smaller and more dis- 

 tant, its head (except for the antennae, which are deep black in both 

 sexes) is entirely red, the scutellum is red, the abdomen with more of 

 the middle infuscate and the two small spots on the pygidium scarcely 

 traceable. Fourth segment of abdomen just traceable across middle, 

 apical fovea with feeble lateral extensions. 



Length 4 mm. 



Ifah. 8. Australia (types in Macleay Museum). 



A remarkably distinct species apart from its peculiar 

 coloration. There is a striking departure in the shape 

 of the intercoxal process of the prosternum in that the 

 front portion is strongly raised and projects backwards 

 so as to overhang like a lip; a character that by some 

 entomologists would probably be regarded as of generic 

 iuiportauce.
