new Species of Histerid*. 17 



Ulster crenatifrons^ sp. n. 



Orbicularis, convexus, niger, nitidus ; antennis pedibusque rufis ; 



fronte utrinque creuata, stria valida semicirculari ; pronoto stria 



interna laterali postice abbreviata, antice post angulum terrainata ; 



elytris striis dorsalibus 1-4 integris, 5 et suturali apicalibus ; 



mesosterno marginato ; propygidio pygidioque parce punctatis. 

 L. 3^ mill. 



Orbicular, convex, black, shining ; the head feebly im- 

 pressed anteriorly, stria well marked and semicircular, punc- 

 tuation sparse and microscopical, the anterior edge before the 

 eye is deeply notched, which enables the funiculus or basal 

 joint of the antenna to be raised vertically, and close to it is 

 a second but less conspicuous notch or emargination, the 

 mandibles are microscopically strigous on the upper surface 

 of their bases ; the thorax is extremely finely punctulate, 

 marginal stria fine and continued behind the head, internal 

 stria strong and a little oblique ; this stria resembles that 

 figured by Marseul for //. torquatus^ except that it is not 

 hamate anteriorly, but ends abruptly before and behind ; the 

 elytra, strise, humeral external deep but shortened before and 

 behind, internal wanting, but there is a very fine short oblique 

 stria at the base of the first stria, 1-4 dorsal complete, the 

 interstices between the first and second and the third and 

 fourth widen out a little at their bases, 5 apical, not reaching 

 the middle, sutural reaches beyond the middle, but is a little 

 shortened apically ; the pygidia are irregularly, not closely 

 nor coarsely punctured ; the prosternum is without striaj, 

 keel narrow and triangular at the base, basal edge obscurely 

 concave j the mesosternum anteriorly faintly arched in outline, 

 stria complete, rather fine and close to the edge ; the meta- 

 sternum has a transverse stria less bowed than the mesosternal 

 stria, the stria continues along the sides and widens out 

 before the posterior coxae; the anterior tibiae are apically 

 dilated, with one strong tooth near the insertion of the tarsus, 

 but the other teeth are ill-defined. 



This species resembles H. torquatas, Mars., but the frontal 

 outline, thoracic stria, and other characters easily distin- 

 guish it.
