small impression on each side towards the front. Thorax 

 a little l)roader than long, the sides a little narrowed 

 towards the base, not at all sinuate; the surface moderately 

 finely and closely punctured, near each hind angle, with 

 an elongate impression. Elyti-a distinctly longer than the 

 thorax, their punctuation rather coarser than, and not 

 (juite so close as, that of the thorax. Hind body de- 

 pressed, cylindric, but little shining ; all the segments, in- 

 cluding the 6th, distinctly punctured along the middle, the 

 jnmctures at the sides becoming shallow striae ; on the 

 under face the striaj along the sides are more deep and 

 distinct, the punctures along the middle sparing. Legs 

 red. 



Ega ; a single individual, which I believe to be a 

 female ; also two specimens from Para, collected by j\Ir. 

 Smith.

Antennre reddish, rather slender at the base, distinctly 

 thickened towards the extremity ; joints 4 — 6 not at all 

 transverse, 7 — 10 distinctly broader than the preceding, 

 each a little transverse. Head narrower than the thorax, 

 rather short; the surface finely and not closely punctured, 

 and with a small punctiform impression on each side the 

 middle towards the front. Thorax broader than long; the 

 sides scarcely narrowed till near the base, Avhere they are 

 a little contracted ; the surface finely and not closely punc- 

 tured, close to each hind angle with a large longitudinal 

 impression, which is sharply limited both on the inside and 

 the outside ; it extends more than half-way to the fi'ont, 

 and is opaque at the bottom, because of a very dense, fine 

 scul])ture. Elytra a good deal longer than the thorax, 

 rather sparingly punctured Avith elongate but not deeply 

 impi'cssed punctures. Hind body flattened, pitchy red, 

 red at the extremity, sparingly and indistinctly punctured. 

 Legs red. INIetasternum with an ill-defined longitudinal 

 impression along the middle. 



Ega; one male and one female individual. 



Obs. — This species is, no doubt, allied to L. linearis,
