NEW MELOLONTHINI FROM AUSTRALIA 313 



Spliyi*ocaIlus. 



Antenna) 9-jointed, third joint quite short, fourth with a 

 small projection in front, the five apical joints very similar to 

 one another, and forming a very elongate club. Maxillary palpi 

 elongate and slender, their 2. nd joint very long, about as long 

 as the 3. rd and 4. th together. Mentum moderately broad, but 

 with the labial palpi much exserted, and apparently contiguous 

 at their insertion. Labrum very large. Hind legs short and thick, 

 except the tarsi which are moderately long and slender. Ventral 

 segments moderately short. The general appearance and colour 

 of this form is much that of the ordinary Melolonthini, such as 

 Rhizotrogus. 



Sphyrocallus brunneus n. sp. Sat elongatus, brunneus, nitidus, 

 thorace corporeque subtus hirsutis; capite fortiter punctate, fronte 

 piligera; elytris striatisi interstitiis pimctatis. Long. 16 1 j 2 mill. 



The labrum is long as well as broad, and its upper surface 

 shining, and only obsoletely punctured: the large clypeus is 

 closely and coarsely punctured, and is separated from the fore- 

 head by a strongly elevated ridge, the hind part of this ridge 

 bears long hairs directed backwards. The thorax is not very 

 closely nor coarsely punctured, and is shining but bears rather 

 numerous, long, depressed hairs, its hind margin is densely pu- 

 bescent, the pubescence extending over the scutellum and the 

 base of the elytra. The elytra are rather deeply striated, the 

 striae being placed in pairs and abbreviated, and the interstices 

 are irregularly punctured, the outer margin is closely ciliated 

 with coarse hairs, and such cilise are densely packed at the 

 rounded, internal, suturai angles. The pygidium and propygidium 

 are coarsely punctured, and bear long hairs. The metasternum 

 is elongate , and as well as the hind coxoe is rather densely 

 clothed with long hairs.
