general appearance is much like the females of laticollis and 

 adelaidae, but differs from them by the tip of the clypeus- 

 being bituberculate as in tHie male. 



By the removal of this species from Oryctes that genus 

 must now be expunged from Australian lists, as barbarossa 

 has been transferred to Haploscapaties, and mullerianus to 

 Pseudoryctes. 



Novapus rugosicollis, Blackb. 

 PL xxvii., figs. 88 and 89. 



There are numerous specimens of this species in the 

 National Museum from the King River, Northern Territory, 

 all marked as taken from termite mounds. The male, hitherto 

 undescribed (the type was noted as a male, but this was 

 subsequently corrected) in general appearance is very close' to 

 the male of N . bifida* (the types of which were also taken 

 from termite mounds) but differs, in having the cephalic horn 

 much less conspicuously bifid, the extent of the prothoracic 

 excavation is much the same, but its walls are more acutely 

 carinated and in front (but not at the apex) and posteriorly 

 (but not at the base) each carina from some directions appears 

 to terminate as a subconical tubercle; b}^ the males alone, 

 however, it would probably have been considered that bifidus- 

 was only a varietal form ; but the females are very distinct, on 

 bifidus the cephalic horn is distinctly bifid ; on rugosicollis it is 

 briefly conical. 



Aneurystypus carinaticeps, n. sp. 

 PL xxvii., fig. 82. 



d . Bright castaneous, some marginal parts narrowly 

 infuscated. TJnder-surface, legs, base of antennae, and ocular 

 canthi, with long rusty-red hair ; elytra with a dense fringe 

 of short pale hair, projecting downwards, and a longer fringe 

 of stiffer redder bristles, projecting outwards, pygidium with 

 a loose fringe of long hairs at the apex, but base glabrous. 



Head with fairly dense punctures on a semicircular space 

 behind the clypeus, base with sparse and small ones. Clypeus 

 with semicircular, strongly-elevated margins; punctures larger 

 than on rest of head, its hind suture marked by a strong 

 transverse carina, subangularly elevated in its middle, 

 and curved on each side so as not to touch the margin. 

 Antennae ten-, club three-jointed ; club very long and almost 

 parallel-sided. Prothorax not twice as wide as long, a 

 narrowly impressed line across front margin ; with small 

 scattered punctures, becoming more numerous, but not 

 crowded towards sides in front. Scutellum almost impunctate. 

 Elytra with a rather deep subsutural stria, elsewhere striation 

 very ill-defined, but the punctures in subgeminate rows.
