Hub. Ceylon (Dr. Templeton and Dr. Thwaites). 



Thorax constricted in the middle, reflexed at the sides. Elytra 

 parallel, a trifle broader than the thorax, nearly the basal third

 transverse costie dividing the surface into quadrangular, generally 

 square spaces. 



Xylobanus gratiosus. 

 (Plate IX. fig. 11.) 



Elongatus, parallelus, opacus, nigro-fuscus ; thorace areolato, 

 rufo-ochraceo, medio constricto ; elytria rufo-ochraceis, parallelis, 

 quadricostatis, interstitiis uniseriatim foveatis. d , $ .

Ilab. Andaman Islands. 



Head pitchy ochraeeous. Thorax, scutellum, and elytra reddish 

 ochraccous. Thorax with five areolets, deeply and angularly con-

 parallel ; the four costae on each elytron are very distinct ; the in- 

 terstices with numerous transverse costae which divide the surface 

 into transverse quadrate spaces. Legs more or less pitchy. The

 transverse costae dividing the surface into transversely quadrate
