800. Abirus ceylonicus, sp. n. 



Piceous, head and thorax with slight aeneous gloss ; legs 

 fulvous. 



Head extremely closely and rather finely punctured ; clypeus not 

 separated from the face, its anterior margin slightly concave ; 

 labrum fulvous ; antennae slender, scarcely extended to the middle 

 of the elytra, piceous. Thorax about twice as broad as long, sides 

 only slightly deflexed, lateral margins feebly rounded, the surface 

 punctured like the head. Elytra subcylindrical, the shoulders 

 tuberculate, the surface strongly transversely rugose, without 

 punctures, the sides with three or four longitudinal rows of 

 tubercles. Legs dark fulvous. Body beneath with greenish gloss, 

 finely pubescent and punctured. 



Length 6| mm. 



Sab. Ceylon (Coll. Jacoby). 



Well distinguished from any of its allies by the sculpturing of 

 the elytra. 



Group MYOCHROINI. 



Body clothed with scales or hairs, subcylindrical or oblong in 

 shape. Antennae subfiliform or with strongly thickened terminal 

 joints. Thorax with distinct lateral margins. Prosternum often 

 provided with grooves at the sides for lodging the antennas. Tibiae 

 often emarginate at apex, claws appendiculate. 



This group contains a number of genera which possess most varied 

 structural characters, although all have in common a convex shape of 

 the anterior thoracic episternum and a pubescent or scaly upper 

 surface. The Indian genera, however, are but few and not difficult 

 to separate.
