DESCRIPTION OF A SPECIES OF OXYPODA NEW TO SCIENCE. 



OxyPODA GLABRIVENTRIS, n. S. 



Elongata, parallcla, ferrugineo-testacea, nitida, suhtiliter parceque punctata, Ion- 

 gihs fiavescenti-puhescens ; antennis validioribus, articulo ultimo elongato ; 

 thorace ceqiwM, postice suh-angustato, angulis posterioribus rotundatis ; elytris 

 hoc vix hrevioribus ; abdomine fere glabra. I. c. If lin. 



In general appearance this species resembles Ischnoglossa corticalis, and in its 

 stout antennae it exhibits a likeness to Ilyobates forticornis ; from both of which its 

 lighter colom* and generic characters will serve to distinguish it. It is closely allied 

 to 0. lucens, Muls. ; differing from that insect as follows : — it is unicolorous, rather 

 larger and more robust, more shining ; its thorax is widest a little above the middle, 

 and much more contracted and rounded ofiF behind ; its punctuation is not so close, 

 and pubescence rather stouter and longer ; its antennse are stouter, with the apical 

 joint longer, and the abdomen is shining, very slightly and remotely punctured, in 

 which respect it recedes from any Oxypoda known to me. 



It is entirely ferruginous-testaceous (though some specimens, in drying up, 

 have the abdomen suffused with a slightly darker tint) ; the head and thoi-ax are 

 moderately, closely, and very finely — the elytra rather more distinctly — and the 

 abdomen remotely and very finely, punctured. The antennae have the 1st and 2rid 

 joints sub-equal and elongate-conic ; the 3rd is shorter than the 2nd, and obconic; 

 4-10 are sti'ongly transverse, gradually widened, and getting slightly longer ; and 

 the 11th joint is elongate, oval at the apex, equal in width to the preceding, and 

 longer than the two preceding joints. 



Several examples (accompanied by Hnmceusa acuminata) were taken in May 

 and June, 1863, by Dr. Power, in the " runs '' leading from a nest (now destroyed) 

 of Formica fuliginosa, at the root of an old beech- tree in Headly Lane, Mickleham, 

 Surrey. 



The characters of antennal development and lack of abdominal punctuation in 

 this insect are so marked, that I bring it forw'ard as undescribed with much doubt ; 

 nevertheless, I can find no species answering to it in the works of Erichson, Kraatz, 

 Thomson, Pairmaire, &c.~E. C. Rye, 284, Kings Road, Chelsea, S.W. 



Occurrence of a Cryphalus new to Britain. — Ckyphalus tili^, Fab., S. E., ii., 

 383 ; Ratzeburg, Forst., i., 164, tab. xiii., fig. 20. I have recently determined this 

 species, which is new to our lists. Redtenbacher places it in a section of the genus 

 wherein the anterior margin of the thorax is armed with teeth ; and, under a mo- 

 derately high power, these teeth, in the present insect, can be distinctly seen ; 

 assuming the form of four small, closely packed, longitudinal ridges, exactly in the 

 middle of the anterior margin. 



In form and size C. tilioe most resembles C abietis, being somewhat short and 

 robust ; C. binodulus is much larger, and C. fagi is much more narrow and elongate. 



The hair-like scales, fonning a kind of greyish pubescence, are much stronger 

 than in the other species, and are distinctly disposed in rows upon the elytra, re- 

 sembling those of Cis villosulws, as contrasted with Cis boleti. 



The thorax exhibits a marked diflfcrence from that of all the other British 

 species, in having the tufted processes which surmount it limited to the upper and
