ever entirely black, a character in which it approaches nearer to 
the European species, for the same part is white at the sides in 
C. villosus, and grayish black in the C. mazillosus. The few hairs 
which I can perceive of the elytra are perfectly black ; they occur 
however almost entirely on the hinder margin of the elytron. It 
is possible that the insect may have had pale markings (which 
have been rubbed off) on these parts, but I cannot trace any pale 
hairs in either of the three specimens. 
The abdomen is clothed throughout with hairs, but they are 
rather less dense than in C. villosus and C. mazillosus ; on the 
upper surface of the abdomen the hairs are black, excepting on 
the second and third visible segments, where they are yellowish 
white, but interrupted with black on the middle of each segment : 
on the under surface the haus are black on the first segment, 
and yellow-white on the second and third segments throughout ; 
the remaining segments are rusty white in the middle only, and 
the pale hairs are almost confined to the posterior margin, the 
sides being black in all the specimens. In C. mazillosus I find the 
fourth segment white throughout beneath, with the exception of 
a small black dot on each side. C. villosus agrees with the Gala- 
pagos insect in having the side of the fourth segment black.

I have placed this Galapagos K/ater im a genus founded by 
Eschscholtz, with which it agrees very closely im many of its cha- 
racters ; as Germaz’s definition of the genus* in question does not, 
however, in all respects apply to the insect before me, it will be 
necessary to notice the pomts of disagreement ; but I will first 
observe, that the Galapagos imsect agrees with Physorhinus in ha- 
ving the tarsi apparently but four-jomted, the fourth joimt being 
very small; in having the third joint short, and produced on the 
under surface into a long, undivided, membranous lobe: the lobe 
in the insect before me is equal in length to more than half that 
of the terminal jomt. The fourth joint is exceedingly small; 
forming a mere node, as it were, at the base of the claw-joint : 
the basal joint is long. The antennez are rather less than half 
the length of the body, and composed of longish, conical, and
