EUCONNUS MAKLINI, Mannkrh. : A XKW BRLTISH BKETLE. 

 BY >^OKMAN 11. JOVT, M.U.C.S , F.E.S. 



While looking over a few beetles lately which I had not been 

 able to identify, and had put aside to examine more carefully on some 

 future occasion, I came across a small Euconnus very distinct from 

 our other British species. As I could find nothing like it in the 

 British Museum collection, I sent it to Herr Reitter, who has kindly 

 returned it to me as Euconnus maklini, Mannerh. I see by the label 

 that I took it here in July, 1901, but, unfortunately, I have no 

 recollection of the exact circumstances of its capture. On the con- 

 tinent it is taken among fallen leaves, aud I think I probably obtained 

 my specimen by sifting decaying leaves, a method which I often employ, 

 and by which I have on several occasions come across ScydmcenidcE. The 

 only book in which I have had an opportunity of looking up the species 

 is C. G-. Thomson's " Skandinaviens Coleoptera." My specimen 

 answers perfectly to his description of Napochus cJaviger, which is 

 synonymous with ScydmcBnus mclkJini, Mannerh., Bull. Mosc, 1844. 

 NapocJiu^is now only regarded as a sub-genus. 



The following is a detailed description of the species -.— 

 Of much the same shape as E. hirlicollii, 111., obscure piceous, shining, very 

 sparingly and finely pubescent, except base of head and thorax, which have rather 

 sparing but coarse bristly pubescence ; antennse, palpi, and legs testaceous ; head 

 slightly narrower than thorax, orbicular ; antennae scarcely longer than head and 

 thorax, robust, and with a very abrupt four-jointed club, first joint ovate, second 

 joint as long as broad, 4 — 7 small, equal, and transverse, 8—10 much larger, very 

 transverse, and of about equal breadth, the last joint about as broad as tenth, sub- 

 orbicular ; thorax as long as broad, narrowed in front, with a deep impression at 

 the base, slightly interrupted in the middle and bounded on each side by an elevated 

 fold ; elytra about three times as long as thorax, widened in middle, with shoulders 

 not prominent, base deeply foveolate, with a strong humeral fold. Long., 1 mm. 



E. maklini may easily be distinguished from the other British 

 representatives of the genus with a four-jointed antennal club by its 

 much shorter and stouter antennae, and abrupt club ; the latter is 

 rather gradual in the other species, aud the joints are not transverse; 

 it is also a somewhat smaller insect.
