EUTHIA FORMICETORUM Reitt. : 



AN ADDITION TO THE LIST OF BRITISH COLEOPTERA. 



BY E. C. BEDWELL, F.E.S. 



Early in July last I captured a siuojle ^ specimen of the above 

 beetle whilst sifting some decaying wood removed from the interior of 

 an old beech tree in the New Forest. The species was briefly charac- 

 terised by Edmund Eeitter in bistable of the genus, in the " Verhand- 

 lungen der k. k. zoologisch-botanischen G-esellschaft in Wien," Band 

 XXXI, Seite 546, as follows : — 



EiTTHiA Steph. 



1.' Pilhler mit stark ahgesetzter dreigliederiger Keule. 

 2." Halsschild ebenso stark als die Fliigeldecken punktirt. 

 4." Fiihler der $ schlank, Glied 5-7 nicht, beim S Grlied 6-8 etwas 

 quer. 



Zienilich schmal, einfarbig gelbroth oder hell briitinlichgelb, 

 die ganze Oberseite massig dicht, gleichmassig, deutlich 

 punktirt. 



liOng. 1"2 mill formicetorum n. sp. 



This may be translated thus : — 



1.' Antennae with strongly discreted, three-jointed club. 

 2." Thorax as strongly punctate as the elytra. 



4." Antennae of $ slender, joints 5-7 not, in S joints 6-8 somewhat 

 transverse. 



Rather narrow, unicoiorous yellow-red or light brownish 

 yellow, the entire upper svirface moderately closely, evenly, and 

 distinctly punctate. 



Reitter gives the distribution of the species as France, Dalmatia, 

 and the Caspian Region ; whilst Ganglbauer, subsequently, records it 

 from France, Illyria (Groerz), and Mediterranean region, with Formica 

 rufa. 



A species of Myrmica was present in the tree, but very few 

 examples occurred, and I quite failed to find the nest of the ant, and 

 could not determine whether the Euthia or Trichonyx sulclcollis Reich., 

 a few specimens of which also found their way to my bottle, was really 

 associated with the Myrmica. 



A visit to the locality a week later, and another in late autumn, 

 failed to produce further specimens of the Euthia, and the Myrmica 

 could not be found, although an additic'nal example of the Trichonyx 

 was revealed, after much search, together with Quedivs ventrnlis Ahr.,
