nated, and the tooth of the mentum strongly bifurcated, 
much more go than in the other sorts. 
Mecodema Percoides : length 12'-15'; of a brilliant black ; 
head and thorax furnished with long brown hair, dis- 
persed round their margin; elytra smooth, with very faint 
longitudinal strie, visible only laterally, and on their pos- 
terior portion ; a series of seven or eight deep punctiform im- 
pressions form a longitudinal line on each elytra, at some 
distance from the lateral margin; end of the palpi and 
trochanters brown. Some specimens have the head much 
smaller. I believe them to be females. 
Mountains of Tasmania. | 
Mecodema Montanum: length 11’; black, brillant ; general 
form rather long and narrow; thorax rather cordiform, 
truncated in front and behind, with the sides rounded 
and becoming narrower toward the back part; an im- 
pression is seen near each of the anterior angles, and a 
few transverse striole on the surface ; elytra oval, rather long, 
covered with feeble longitudinal striz ; a line of deep punc- 
tiform impressions follow the margins ; these impressions 
- are more numerous on their posterior part; parts of the 
mouth, legs, and base of the antennz rather brown ; the 
remaining part of the latter hirsute; a few long brown 
straight hairs are dispersed on the sides of the head and 
thorax. 
From the mountains of Victoria. 
MAORIA. 
This new genus is distinguished from JMecodema by its 
palpi, which, instead of being more or less securiform, are 
terminated by an oval article ; the tooth of the mentum is 
simple and not bilobed ; the legs are stronger, the thighs in- 
flated; the front tibize are more strongly palmated, and 
those of the other two pair are dilated at their extremity, 
and protrude in the form of a strong point; the tibie are 
all straight, the anterior armed with two very long spurs on 
the inner side ; the mandibule are strong; all the sorts 
known are from New Zealand. . 
Maoria Tibsalis : length 94° ; black, with a rather brown 
tinge ; head smooth, with a transverse depression behind the 
eyes; thorax rather cordiform, rounded and marginated 
laterally, with the anterior angles rounded and impressed, a 
very deep punctiform impression on each of the posterior 
angles ; elytra oval, very strongly striato-punctated ; a longi- |
