CHllYSOMELIDJE. 
base of antennae metallic blue, rest purplish ; labrum piceous ; 
palpi fulvous, apical joint piceous ; antennae black, half the length 
of body, basal four joints fulvous, third and fourth equal. Thorax 
twice as broad as long, sides obliquely narrowed in front, angulate 
behind the middle ; disc rather convex, finely and not very closely 
punctured, sides scarcely more strongly or closely punctured. 
Elytra subquadrate, distinctly transversely depressed below base, 
extreme lateral margins blue ; puncturation fine and regular near 
the suture, coarse and close at the sides ; an obsolete short costa 
below shoulders. Posterior femora with a small tooth. 
Length 4\ mm. 
Hah. Burma : Karennee. Type in Genoa Mus. 
Distinguished by the purplish coloration, evenly and finely 
punctured thorax, and its convex shape. 
526. Nodostoma convexicolle, sp. n. 
Violaceous or metallic green ; basal joints of antennge and 
labrum fulvous ; abdomen black. 
Oblong. Head closely and strongly subpunctate-rugose, vertex 
longitudinally strigose ; clypeus deeply concave-emarginate ; an- 
tenme black, basal three joints fulvous, basal joint black above, 
second to fourth gradually lengthened, terminal joints elongate. 
Thorax about twice as broad as long, sides distinctly angulate near 
base, strongly obliquely narrow r ed in front, anterior sulcus deep 
and entire ; surface convex, closely and finely punctured, punctures 
of equal size, evenly distributed. Scutellum oblong, black. Elytra 
convex, narrowed at apex, deeply transversely depressed below 
base, strongly and regularly punctate- striate, the punctures closely 
placed ; shoulders very prominent. Legs black, femora with a 
minute tooth ; flanks of thorax smooth, with a few oblique strigae. 
Length 6|-7g mm. 
Hah. Assam (Coll. Brit. Mus.). 
One of the largest species of the genus, which besides its size 
may be known by the rugosely punctured head and convex surface 
of the thorax ; these seem to be males : whether two bright 
metallic-green female specimens of larger size, with a shorter and 
more transverse thorax, metallic legs and stronger femoral teeth, 
are the other sex of this species is doubtful, they agree, however, 
in every other detail with the violaceous form ; their locality is 
simply marked “ India or.”

J . Dark blue ; basal four joints of antennae fulvous ; abdomen 
black ; tibiae dark piceous. 
Head and clypeus strongly punctured, the punctures more
