STENID.E. BLEDIUS. 307 



bark of elms — in the latter locality the insect appears to abound. I 

 have taken one specimen (flying) in my own garden. 



Genus DXXX. — Bledius, Leach. 



AntenncE geniculated, a little thickened at the apex^ the basal joint very long, 

 curved, clavate, second and third obconic, the last rather longest, the 

 remainder short, the teniiinal one being ovate-obtuse. Palpi unequal, 

 maxillary with the second and third joints large, ovate, subclavate, the 

 terminal one slender, elongate-cylindric : lahrum transverse : mandibles 

 stout, armed within towards the apex with a strong tooth : body linear, 

 cylindric ; head and thorax armed with horns or tubercles : eyes small, pro- 

 minent: elytra remote, with the angles rounded: legs short ;JeTOO?'a simple; 

 tibios entire, four anterior compressed, densely pectinate-denticulate without, 

 the two posterior smooth, curved backward and densely ciliated ; tarsi 

 slender, retractile, distinctly quadri-articulate, the terminal joint longer than 

 the others united, pilose. 



This, as also the following genus and Trogophloeus, are distin- 

 guished by having the antennae geniculated, that is, the basal joint 

 is so long and the second so attached, as to give the appearance of 

 the antennae being bent, or broken as it is termed : from the genus 

 last-mentioned, however, the denticulated outer edge of the anterior 

 tibiae at once distinguish Bledius, while this genus may be known 

 from Hesperophilus by having the body generally convex, with the 

 head more or less horned or tuberculated, and the thorax also slightly 

 so in front: — the Bledii generally inhabit the sandy shores of the sea 

 or its estuaries, and appear to be gregarious.

Black, slightly shining, deeply punctate : head depressed in front, produced on 

 each side above the base of the antennae into a short stout curved porrected 

 horn, as long as the clypeus : thorax moderately convex, deeply and coarsely 

 rugose-punctured, the anterior margin produced in the middle into a long 

 slender porrected glabrous horn, with a groove above, in continuation of the 

 usual dorsal channel : elytra rather deeply and thickly punctured, rusty- 

 red, with the base and suture pitchy black ; abdomen finely punctured, its
