smooth. Elytra scarcely perceptibly depressed below base, very 
strongly punctured, at sides finely transversely strigose, sparingly 
longitudinally costate ; shoulders prominent, densely punctured. 
Head and thorax with short golden hairs, elytra with rows of 
erect golden pubescence. 
“ Length 7-8 mm. 
“ Bab. Andaman Islands.” ( Lefevre .) 
799. Abirus igneicollis, sp. n. 
Dark blue or violaceous ; antennas and legs nearly black ; head, 
thorax and scutellum golden cupreous. 
2 . Head closely semirugosely punctured ; clypeus distinctly 
separated from the face, punctured 
like the head ; labrum, palpi and 
mandibles piceous ; antennae with 
the terminal five joints very elongate 
and slightly dilated, third and fourth 
equal, slender, last joint reaching 
beyond the middle of the elytra. 
Thorax subcylindrical, strongly trans- 
verse, the lateral margins rather 
strongly rounded at the middle, an- 
terior angles produced into an acute 
point ; the surface extremely closely 
and evenly punctured, the punctures 
more crowded at the sides, the inter- 
stices at the latter place wrinkled, 
those on the disc impressed with some 
very minute punctures. Scutellum 
bright cupreous, smooth. Elytra 
wider at the base than the thorax, 
subcylindrical, the shoulders prominent, deeply impressed within ; 
the puncturation very similar to that of the thorax, the inter- 
stices below the shoulders transversely rugose as far as the middle; 
the suture near the apex accompanied by a deep, short, elongate 
sulcus. Posterior tibiae strongly widened at the apex ; claws 
appendiculate. Prosternum subquadrate ; anterior margin of 
thoracic episteruum convex. 
8 . Antennae with the terminal five joints broadly dilated. 
Yar. Above entirely dark blue or cupreous. 
Length 7-7 1 mm. 
Bab. Burma {Coll. Brit. Mus.). 
This is a species in which the sexes differ greatly in the struc- 
ture of the antennae, a rare occurrence in this genus. The male 
is as usual further distinguished from the female by the dilated 
first joint of the anterior tarsi.
