and Gyrinidee of Australasia. 17 
I have received the species from Mr. Stevens, from New Holland ; 
Mr. Bakewell has taken it in S. Australia, and placed an example 
from his cabinet in the collection of the British Museum. 
3. C. adumbratus, n. sp. 
C. ovalis, brevior, flavus; capite flavo, ad basin transverse nigro ; thorace 
ad latera rotundato, margine basali recto haud sinuato, impunctato, 
levi, ad apicem transverse depresso et punctatulo, flavo; scutello fusco- 
niero; elytris latis, punctorum seriebus obsoletis duabus sparsorum, 
harum utraque biserie macularum nigrarum minuta compressa, notata 
inter has lineas; elytris crebre nigro notatis veluti vermiculari, infra 
medium et apicem juxta transverse nigro adumbratis; pedibus an- 
tennisque rufo-flavis: infra nigro-rufus. 
Long. corp. 5 lin., lat. 2? lin. 
This species nearly resembles C’. consputus of Sturm ; it is broad, 
short, and of a pale flavous colour. The markings of its elytra, when 
seen under a high power, are very different: instead of circular closely 
arranged dots, the surface is covered with connected tortuous mark- 
ings, not fine as if scratched with a needle, but broad and closely 
arranged ; these markings are interrupted by two longitudinal lines, 
each formed by a double line of more continuous black dots, together 
forming between them a longitudinal white marking ; along these two 
white markings are arranged sparingly and faintly minute punctures ; 
the surface is postmedially clouded over with black (especially near 
the suture), and also less broadly so near the apex. 
I have received, at different times, three examples of this species 
from Mr. 8. Stevens and Mr. Cuming, from the New Hebrides. 
4, C. australis, Aubé (Sp. Gén. p. 236). C. rufimanus, White 
(Zool. Ereb. & Terror, Ent. p. 6, 1844). 
A yery abundant and slightly variable species ; it is found in New 
Zealand, the Fiji Islands, and in different parts of Australia and 
Tasmania; three examples that I have received from the interior of 
New Zealand are decidedly smaller in size. I hesitate in referring 
the species (from a consideration of the examples before me) to C. 
pulverosus, Sturm, as has been suggested.
