SOME NEW SPECIES OF GABRIUS. 

 BY NORMAN H. JOY, M.E.C.S., F.E.S. 



Plate I. 



Some luouths ago Herr Edmund Reitter sent me for examination 

 about 600 specimens of the Coleopterous genus Gabrius from various 

 parts of Eastern Europe, chiefly from the Caucasus Mountains and 

 their neigboui'hood, and Austria. I found it necessary to dissect out the 

 sedeagus in nearly all the males. Fortunately, in every species but G. 

 stipes, which can be easily identified without dissection, the male may be 

 recognised by a slight emargination of the hind margin of the under plate 

 of the last segment of the hind-body; and a triangular groove leading 

 from it on the nnder-surface of the segment. It can often be seen 

 whether this is present or absent without removing the insect from the 

 card. The results of this examination have been the discovery of seven 

 new species, and evidence of an extensive range in the case of some of 

 those described by Dr. Sharp. I have also examined a few specimens 

 belonging to Mr. Champion and Dr. Cameron, mostly from Spain and 

 the Mediterranean area. One of Mr. Champion's proves to be new, 

 and has the most primitive form of sedeagus in the genus. In all the 

 following new forms the colour probably varies somewhat, and is of 

 little help in the identification of the species ; it is therefore not 

 generally given in the description. The head is black, the thorax black 

 or pitchy, the elytra pitchy or reddish-brown, the hind body black, 

 with the extreme apex yellowish red. The colour of the base of the 

 antennae and legs is more important. The antennse are black, with the 

 base yellow in some species. The legs are reddish-yellow, the middle 

 and hind tibiae being dark in certain species. The elytra are longer 

 than the thorax, except in G. tormis. There appears to be no sjDecific 

 distinction in the punctuation. I have thought it best to compare each 

 species in form and size to one of those already known, rather than to 

 give a detailed description and exact measurements of each. 



G. PRIMIGENIUS, Sp. nOV. 



Resembles G. keysianus; base of antennse and legs dark; head in J distinctly 

 longer than broad ; ajdeagvis bkuit at apex, whicli is slightly tliickened. 

 Hab. : N. W. Spain, Pontevedra. One ^J . 



G. CYPHONOTUS, sp. IIOV. 

 Mncli like G?. pennatns ; base of antennae clear yellow ; ^ with head slightly 

 elongate ; sedeagiis with the apical piece not sharply defined as in Q. nigritidxis. 



Hab. : Caucasus and the borders of the Caspian Sea ; Daghestan, 

 Lenkoran, etc. Many specimens.
