Hah. Sumatra {Sir Stamford Rajffles). 



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

 colour flesh-colour, and the thorax has the sides less reflexed. 

 Rostrum reddish testaceous, a little longer than broad. Antennae 

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

 sides moderately reflexed, the posterior angles prominent and acute, 

 the disk somewhat infuscated. Scutellum black, parallel at the 

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

 larged posteriorly, the sides rather straight, 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 elytrisque ferrugineo-rufis, 

 regione scuteUari anguste infuscato. Long. 6 lin., lat. 2'^ lin.
