 tracted and has two obsolete fovese, hinder angles not quite 

 rectangular, but more or less obtuse. Elytra oblong, humeral 

 angles rounded, sides rather parallel, disk irregularly and more

" Taken in plenty on the southern coast of Devonshire, beneath 

 stones at the mouths of the rivers Tamar and Yealm; and at 

 Tamarton, Bantham and Kingsbridge." Dr. Leach. Berwick- 

 upon-Tweed. " Ballyhuish Ferry, Scotland." Mr. Curtis. Found 

 in great abundance also by my friend Mr. Adam White, at South 

 Queensferry, at low water, in the interstices of the stratified 

 sandstone into which silt had been washed by the tide. " Strang- 

 ford Lough, Ireland." Mr. Holiday.

 oblongo-ovatis, Isevigatis, punctisque tribus vel duobus 

 impressis.

This insect, which bears a close affinity to the preceding, differs 

 in the following particulars. The posterior angles of the thorax 

 are more rotundate ; the elytra are more narrowed and rounded 

 in front and the sides are distinctly rounded instead of being 

 parallel ; the mandibles are less prominent ; and the spine 

 beneath the penultimate joint of the anterior tarsus is shorter 

 and less curved; the entire upper surface is likewise more 

 glabrous and shining. Mons. Laboulbene, in the seventh volume 

 of the " Annales de la Societe Entomologique de France," has 

 fully described the species from examples captured near Boulogne. 

 I have received specimens from Scotland of both insects, which 

 will probably be found mixed up in collections. Mr. Wollaston
