and that I have good reason to believe only three of those nine 
to be before me. 
With these introductory remarks I will proceed to furnish a 
tabulated statement of the characters of the species known to 
me, from which I have to exclude all the species not in my 
possession on account of there not being one of them of which 
the organs of stridulation have been definitely described. 
I regret that I am not able to deal more comprehensively with 
these insects, but hope nevertheless that my work (such as it is) 
will be useful as forming a foundation on which better work may 
be done in the future to elucidate a genus whose species have not 
yet been treated with anything more systematic than isolated 
diagnoses. 
Referring to the diagnoses which follow I may say that I have 
not included in them characters that seem to be generic, such as 
the presence of villosity on the undersurface and legs, the 
antennal structure, &ec., as it needlessly lengthens descriptions to 
include in them matters that do not concern specific distinctions. 
A. Front claws of male simple. 
B. Propygium with organs of stridulation. 
C. These organs consist of two longitudinal 
rows of numerous fine ruge. 
D. Base of prothorax with a continuous 
marginal border... pecuarius, Reiche. 
DD. Base of prothorax margined only close 
to the sides puncticollis, Macl. 
CC. The organs of stridulation consist of only 
one or two much larger and more 
elevated rugze Meyricki, Blackb. 
BB. Propygidium devoid of ‘organs of stridula- 
tion. 
C. Elytra very coarsely punctulate. 
D. Prothoracic puncturation ea aera 
fine ; Australasie, Hope. 
DD. Prothoracic puncturation “extremely 
coarse. Terre-reyine, Blackb. 
CC. Elytra with scarcely visible puncturation nasutus, Blackb. 
AA. One of the front claws of male bifid (propygi- 
dium with organs of stridulation in all the 
species known to me). 
B. Two tubercles on the clypeal ridge. 
C. Elytra distinctly punctulate ... ... bidens, Blackb. 
CC. Elytra almost without puncturation ... levipennis, Blackb. 
BB. Clypeal ridge without tubercles ... ... tmtermedius, Blackb. 
I. Meyricki, sp. nov. Mas. Sat late ovatus; nitidus; obscure 
ferrugineus, capite prothoraceque nigricantibus, ‘antennis 
palpisque brunneo-testaceis ; clypeo aparsim punctulato, vix 
ruguloso, antice rotundato-truncato, marginibus sat reflexis, 
lateribus sat fortiter sinuatis ; fronte a clypeo per carinam 
simplicem divisa, sparsim leviter ruguloso-punctulata ; pro-
