L. rather smaller and narrower than the L. Cheiranthi, less 

 densely clothed with a minute ashy pubescence, but (like that 

 species) ornamented with a broad paler line along its sides; also 

 less opake. Rostrum rather longer and slenderer than that of 

 L. Cheiranthi; also a little more curved, subcariuated posteriorly, 

 very minutely punctulated, and with rather larger punctures in- 

 termixed. Frothorax much more deeply and remotely punc-

 but indistinct paler line. Elytra gradually a little narrowed 

 behind, and with the extreme apex of each more produced or
