‘Challenger’ Coleoptera. 283 
Miolispa suturalis, Pascoe. 
The specimen brought is entirely black, except a yellow 
stripe on each elytron. It does not, however, appear to differ 
in any other respect from the usual red examples with black 
head. 
TAHITI (Lake Wathiria). 
Anchomenus anachoreta, eremita, and monticola, Fairm. 
The three species brought by the Expedition from Lake 
Waihiria appear to correspond with the three described by M. 
Fairmaire (Rev. Zool. 1849, p. 283) from the same locality. 
If this be the case, however, his descriptions are not strictly 
accurate. 
He states that A. anachoreta and A. eremita have the strize 
of the elytra impunctate. This can only apply to the dorsal 
strie, as the lateral ones are distinctly punctured, and even 
the dorsal striz are seen to have punctures if the insect is 
viewed obliquely. The punctures are more obscure in A. ere- 
mita than in A. anachoreta. The sculpture of the interstices 
of the striz of the elytra is so excessively fine and delicate 
in A. eremita that it can only be seen with a strong magni- 
fying power, and the interstices consequently appear highly 
polished. In A. anachoreta the sculpture is still very fine, 
but’ is seen much more easily, whilst in A. monticola it is 
visible with a weak magnifying-glass and renders the surface 
slightly opaque. 
It appears to me from description that Dyscolus castaneus, 
Bohem. (‘ Kugenies Resa,’ p. 16) is the same as A. monticola. 
These species are correctly placed under the genus Colpodes 
in the Munich Catalogue.
