252 Mr, J.S. Baly’s Further Descriptions of 
and entirely different colour will distinguish it from Ch. basalis, 
its narrower form from Ch. Lecontii, the different colour and form 
of thorax from Ch. nigrita, and its much narrower and more elon- 
gated shape from Ch. Pilate: and all the other species in the 
present paper.

Hab. Carolina. 
In my own Collection and that of the Rev. H. Clark, to whom 
I am indebted for a specimen, 
Thorax distinctly longer than broad, sides slightly rounded, 
narrowed in front; surface very closely covered with large deep 
punctures, almost rugose ; base of thorax indistinctly depressed 
transversely, but without any trace of sulcation; apex of elytra 
minutely serrate. 
The entirely black colour, together with the shape of the thorax, 
at once separates this insect from its congeners.

‘Nigra, prothorace tantum rubro: prothorax profunde punc- 
tus; utrumque elytron 3-carinatum, marginibus quoque 
elevatis ; interspatiis seriebus 2 punctorum profundorum im- 
impressis. Insectum longum (corp. long. °175 unce., lat. °05 
unc.)”

Mr. Newman has omitted to mention the black apical and basal 
margins of the thorax, which are very marked in the present 
species. I venture to correct his description, having one of his 
typical specimens in my own possession. I have reproduced his 
description entire from the “ Entomologist,” the latter being a book 
seldom to be met with. 
As stated under Ch. ruficollis, the more cylindrical body and 
coarsely punctured thorax will distinguish Ch. Ariadne from its 
allies.
