364 Mr. F. Bates's descriptions 
Micrectyche ferruginea, n. sp. 
Oblong -ovate ; pilose ; dull feiTuginous ; prothorax 
clouded with black marks ; eljtra a little shining : much 
more robust than the preceding ; prothorax broader, the 
lateral margins less distinctly expanded, and feebly crenu- 
late at the edges, the prebasal emargination feebler and 
shallower, the base more gradually and less strongly 
roimded ; elytra broader and shorter, more massive ; hu- 
meral angle strongly dentiform, intervals wider, the 
punctuation better defined, less muricate, less transversely 
confluent, the sutural intervals much less evidently 
smoother and brighter; legs and antenna? more robust, 
pale ferruginous, shining ; 3rd joint of antenna? decidedly 
longer than the 4th, the 11th subglobosc : tibia? short, 
straight, triangular ; the anterior not spinose at outer 
edge ; inner edge straight throughout ; outer apical angle 
produced into a strong bifid tooth. 
Long. If lin. 
Ilah. — Swan River. Two examples. 
Var. ? duhia. — Smaller and much less robust: pro- 
thorax not clouded Avith black marks : disk of elytra 
clouded with fuscous ; the punctures in line larger, the 
intervals more coarsely sculptin-ed : prosternum between 
the coxa? a little broader and longitudinally concave. 
Long. H lin. 
Hab. — Champion Bay. One example. 
The general form of this var.? is more like that of 
M. intermedia, but the tibire are differently formed ; the 
3rd joint of the antenna? is decidedly longer than the 4th, 
the lateral margins of prothorax are much less distinctly 
expanded, the base less strongly and more gradually 
rounded, and the colovir is entirely dull ferruginous ; in all 
these respects it agrees more closely with J\l. ferrucjinea. 
A knowledo'C of the sexual character would determine 
to which, if to either, this var. ? belongs, and also Avhether 
both it and M. ferrucjinea are really and specifically dis- 
tinct from intermedia ; at present I am compelled to hold 
them so. 
Micrectyche Ryei, n. sp. 
Elongate-oval, slightly depressed ; pilose ; dilute pitchy- 
feiTuginous ; prothorax clouded with black marks, less 
c()n\cx, and less strongly rounded at the sides posteriorly, 
than in the preceding ; the lateral expanded margin feeble, 
the prebasal emargination lunate, the base slightly and
