NODOSTOMA. 307 



labrum fulvous ; antennae filiform, about half the length of the 

 body, third and 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. Prosternurn strongly 

 punctured. 



Length 4 mm. 



Hob. Bengal : Mandar ; Burma : Bharao. 



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. 



cf . 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. Scur/ellura 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. 



Hab. Burma : Euby 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.
