NEW MELOLONTHINI FROM AUSTRALIA 319 



moderately broad and long, the labial palpi very short and not 

 quite contiguous at their base. Labrum very large, its front 

 margin elevated and sharply defined. Hind legs short, rather 

 thick, their tarsi long and slender. Ventral segments very short. 



Trichelasmus pilicollis n. sp. ^Nigricans, opacus, elytris velutinis, 

 prothorace corporeque sublus fulvo-hirsitlis , antennis pedibusque 

 rnjisj, illarum clava infuocata; elytris striatis; pygidio laevi, ni- 

 tido. Long. 11-12 millim. 



Upper surface of labrum shining and impunctate. Head coar- 

 sely but not very densely punctured. Thorax finely punctured, 

 but the sculpure quite concealed by a long, dense pubescence 

 of tawny colour. Elytra very dull, quite distinctly striated but 

 with the external striae obsolete, the striae when closely exa- 

 mined are seen to be obsoletely punctured. Legs entirely red. 



Found by M. r Brewer in South west Australia. My two in- 

 dividuals were not found together, one is labelled, Albany, 

 the other K. Geo. Sound; they shew some slight distinctions 

 which may be either sexual, or characteristic of two very clo- 

 sely allied species. 



Enamillus. 



Antennas 9-jointed, third joint rather long, the six apical 

 joints about equal in size, and forming a large club, the first 

 and last leaves of which on the under face enfold and w T rap 

 over the others, the lamellae furnished on their inner faces, 

 with dense, fine, erect hairs. Mentimi short, labial palpi not con- 

 tiguous at their base. Labrum very large. Hind legs short, not 

 very thick, their tarsi long and slender. Ventral segments extre- 

 mely abbreviate. 



This form is extremely similar to Trichelasmus, but has six long 

 lamellae to the antennae. The mentum also appears to be diffe- 

 rently formed, but this I cannot very well distinguish in the 

 only individual at my disposal.
