NODOSTOMA. 
307 
labrum fulvous ; antennas filiform, about half tlie length of the 
body, third aud fourth joints equal, elongate. Thorax half as broad 
again as long (more transverse in $ ), sides oblique, feebly angulate 
close to base, anterior portion strongly narrowed, the submarginal 
sulcus very deep and entire ; surface very closely, evenly and 
strongly punctured, the punctures very crowded at the sides and all 
larger than the interstices. Elytra oblong, very feebly impressed 
below base, rather closely and finely punctate-striate, punctures 
distinct to apex. Breast dark blue. Prosternum strongly 
punctured. 
Length 4 mm. 
Bab. Bengal : Mandar ; Burma : Bhamo. 
Described originally from a single specimen, but received since 
in considerable numbers from Mandar. The thorax in the male 
insect is less transverse than in many of its allies, the lateral angle 
but little marked, and the puncturation very close and even, 
especially on the elytra. 
Sides of thorax rounded. 
528. Nodostoma gracilipes, sp. n. 
Metallic dark blue ; antennae (basal joints excepted) and under- 
side black ; palpi fulvous ; tibiae and tarsi black. 
d . Subelongate ; head remotely and rather finely punctured ; 
clypeus not separated, anterior margin concave ; labrum piceous ; 
basal joints of palpi fulvous, apical joint black : antennae with the 
basal three joints fulvous, rest black, third joint much shorter 
than the fourth, terminal joints elongate and slender. Thorax sub- 
cylindrical, half as broad again as long, sides rounded, widest at 
middle ; surface somewhat flattened, with the anterior portion rather 
deflexed at sides, more closely but scarcely more strongly punc- 
tured than the head, punctures evenly distributed and of equal size ; 
sides of disc with a shallow depression (in $ )> anterior margin 
preceded by an obsolete transverse groove at the sides only, basal 
margin with deep groove. Scutellum oblong-ovate, impunctate. 
Elytra much wider at base than thorax, rather elongate, very 
strongly and closely punctured, the punctures in approximate rows 
near suture, irregularly arranged at the sides; interstices slightly 
transversely rugose near shoulders. Legs slender, femora unarmed, 
apex of tibiae clothed with yellow pubescence ; first joint of tarsi 
dilated, more slender in the female. Prosternum rather broad, 
strongly punctured. 
5 . Elytra rather more strongly and closely punctured, sides 
below shoulders with two short elongate ridges. 
Length 4-5 mm. 
Hah. Burma : Kuby Mines. Type in Brit. Mus. 
The rather narrow elongate shape, close and strong punctura- 
tion of elytra, non-angulate thorax, and the elytral costae of the 
female separate this species from other metallic forms.
