Lycostomiis vulpinus. 



(Plate 11. fig. 8.) 



Fusco-niger ; rostro, thoracis limbo elytrisque rufo-testaccis, his 

 postice sat ampliatis, apice nifis. Long. 6 lin. 



Hah. Sumatra {Sir Stamford Baffles). 



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

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

 Eostrum reddish testaceous, a little longer than broad. Antennae 

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

 sides moderatel}' 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. 



(Plate II. fig. 10.) 



Niger, opacus ; thoracis lateribus elytrisque ferrugineo-rufis, 

 regione scutellari angusto infuscato. Long. 6 lin., lat. 2^ lin. 



Hab. Bootan (Pemberton), India (Boys). 



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