Near L. similis, Hope, but the teguments are more delicate, the 

 colour Mesh-colour, and the thorax has the sides less refiexed. 

 Rostrum reddish testaceous, a little longer than broad. Antennae 

 rather shorter than in similis and less broad. Thorax with the 

 sides moderately refiexed, the posterior angles prominent and acute, 

 the disk somewhat infuscatcd. Scut ell um black, parallel at the 

 sides, truncate at the apex. Elytra gradually but not much en- 

 larged posteriorly, the sides rather Btraight, only arcuate near the 

 apex : the third costa is somewhat indistinct, the fourth is strong, 

 and forms a strong well-marked carina over the shoulder, more ele- 

 vated than in similis. 



Lycostomus modestus.

Niger, opacus ; thoracis lateribus elytrisquc ferrugineo-rufis, 

 regione scutellari angusto infuscato. Long. G lin., lat. 2\ lin.

Opaque above. Rostrum a little longer than its width at the 

 base, narrowed towards the apex. Antennae narrow and linear.

 Elytra dull red, slightly wider at the apex ; each elytron with 

 four equidistant costoe ; the interstices with rough transverse reticu-

 cation of an interrupted intermediate costa. 



£ . Antennas a little more than half the length of the elytra, 

 rather slender, all the joints elongate.
