About the sizeof />. tcnninatiDn, hut of totally differcut 

 colour, and with the head larger and dillereutly shaped. 

 Antenuie yellow, about as long as head and thorax, 

 formed much as in L. tenniufitum, but slightly stouter, 

 the pemdtimate joints a little shorter; 3rd joint distinctly 

 longer than 2nd. Head about as broad as the thorax, the 

 hinder angles not rounded, the front part sparingly and 

 rather coarsely punctured ; the disc shining and impunc- 

 tate ; the hind angles densely and finely punctured. 

 Thorax su1)quadrate, straight at the sides, quite as long 

 as broad, a little narrower than the elytra ; a broad line 

 along the middle impunctate ; the sides moderately 

 coarsely and not closely punctured ; the medial ])unctures 

 at the liind part separated from the others by a narrow, 

 smooth space. Elytra rather longer than the thorax, 

 finely and not closely ]nmctured, the punctures indistinctly 

 arranged in lines. Hind body with the basal segments 

 ])itcliy, the hind part reddish-yellow, very finely punctured. 

 Legs yellows 



In the male the 6th segment of the hind body beneath 

 has a longitudinal impression along the middle ; its hind 

 margin is broadly but very shallowly emarginate, the 

 cmargination limited on each side by a slight projection ; 

 the 7th segment has a rather bi'oad and deep notch, the 

 front part of which is rounded, and not notched.

Mas: abdomine segmento 7° ventrali apice sat pro-

Extremely close to /,. rufulum, and differing only as 

 follows: the antenme are rather longer, the 3rd joint 

 considerably longer than the 2nd, the thorax is more 

 closclv ])unctured : and in the male the 6th segment of 

 the hind l)ody beneath has a broader, ill-defined impres- 

 sion, at the extremity of \vhich is a triangular impunctate
