Hah. North America. 



Forehead produced between the antennae into a flattened process, 

 which is slightly concave above, truncate in front ; it is a little 

 broader in the female than in the male. Thorax rather broader 

 than long, with the sides reflexed ; the surface is divided into seven 

 areolets, the discoidal ones shallow, the lateral ones deep ; the three 

 anterior carinse are parallel, the outer ones of these three are con- 

 tinued posteriorly and curved somewhat in the form of reversed 

 brackets )(, so as to enclose the posterior mesial areolet, which is 

 closed posteriorly by the base of the thorax. The elytra are sub- 

 parallel, each with four very well-marked shining costiB; the inter- 

 stices have numerous rather less elevated transverse shining ridges, 

 which are either straight, oblique, or divided into two halfway across 

 the interstice. 



XYLOBANUS. 



Rostrum none. Antennae dentate. Thorax with five or seven 

 areolets, the lateral ones sometimes obliterated. Elytra each with 

 four costae, the interstices with regular transverse costae. 



The type of this genus is Lycus costifer, Walker.

Hah. Ceylon {^Dr. Temphton). 



Head pitchy, shining, with four shallow foveae between the eyes. 

 Thorax with the sides moderately reflexed. Elytra parallel ; each 

 elytron with four strong costas ; the interstices with numerous 

 transverse costje dividing the surface into quadrangular, generally 

 square spaces.
