XII. Additions to the Catalogue of British Coleoptera, with 
Descriptions of new Species. By G. R. Crorcu, 
B.A., and D. Suarp, M.B. 
[Read 19th November, 1866.] 
New SpecliEs. 
We have appended our initials to the description of each species, 
in order to obviate the criticism of Dr. Kraatz, that two authors 
cannot describe the same species. 
1. Plilium concolor. 
P. parallelum, nigrum, opacum, dense subtilissimeque punc- 
tatum, pube brevi albida vestitum; prothorace transverso, 
postice fortiter angustato, haud canaliculato; elytris thorace 
vix latioribus sed illo plus quam triplo longioribus ; antennis 
pedibusque piceis. 
Long. § lin. 
This is a very remarkable species, and may be known by its 
narrow and parallel form, its thorax very evidently broader than 
long, and very much narrowed behind; its elytra not dilated at 
the sides, scarcely wider but more than three times longer than 
the thorax. Mr. Matthews, who has kindly examined the insect, 
assures me that I am correct in considering it a species hitherto 
undescribed. 
I found a single specimen among the coarse sand and shingle on 
the banks of the Bowmont at Yetholme; Mr. Crotch was with 
me at the time, and though we saw other specimens, we could not 
secure them, owing to the minute size of the creature and its pe- 
culiar habitat. Its principal companion was T'hinobius longipennis. 
I had intended giving myself the pleasure of dedicating this 
species to the Rev. A. Matthews, but as his name has already 
been attached to a species of one of the neighbouring genera, I 
have been obliged to choose another name for the curious little 
creature.—D. 8S. 
2. Atomaria Wollastoni. 
A. oblonga, subcylindrica, fusca, minus fortiter sat confertim 
pUnctata, tenuiter cinereo-pubescens ; prothorace coleopteris
