ABIRUS. 
459 
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 64 mm. 
Hob. 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. Antennge subfiliform or with strongly thickened terminal 
joints. Thorax with distinct lateral margins. Prosternum often 
provided with grooves at the sides for lodging the antennae. 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.
