178. Xuthea metallica, Jacoby. 



Pseudodera metallica, Jac, Arm. Soc. Ent. Belg. xl, 1896, p. 267. 



Body elongate and parallel-sided. Colour metallic-green ; 

 antennae, tibiae, and tarsi brown; labruin black, margined with 

 brown ; underside more coppery in colour, but with a less metallic 

 sheen. 



Head with vertex generally impunctate, except for a few 

 scattered punctures in front and some more near the base in 

 certain examples ; there is a deep oblique sinuous impression at 

 each side above the base of the antenna ; frontal tubercles rather 

 small, triangular, interantennal carina raised and Jong, clypeus 

 rugose, labrum impressed with a row of deep punctures. Antennas 

 extending beyond the middle of the elytra ; first segment thickened 

 and club-shaped, second half the length of third, fourth nearly as 

 long as the preceding, fifth longer, sixth and seventh each slightly 

 shorter than fifth but equal to each other, eighth, ninth, and tenth 

 almost equal, eleventh slightly longer; the six apical segments 

 slightly thickened ; the relative lengths of the segments vary to a 

 certain extent in the sexes. Proihorace somewhat broader than 

 long (not twice as broad as long, as Jacoby erroneously states), 

 sides very slightly rounded, very narrowly margined, anterior 

 lateral angles somewhat expanded and posterior angles pointedly 

 produced ; the ante-basal transverse depression, which is bounded 

 on each side by a perpendicular impression, is much deeper than 

 in X. orientalis. Scutellum triangular, apex rounded, surface convex 

 and impunctate. Elytra broader at base than prothorax ; at the 

 base, internal to the prominent humerus, is a distinctly convex 

 part ; surface regularly punctate-striate, ench elytron having 

 eleven longitudinal rows of punctures, including a scutellar and 

 an extreme marginal row ; the seriate punctures themselves 

 become rather obsolete near the apex, which is sub truncate ; 

 intervals smooth. Underside : all the tibiae with a little spine' at 

 the apex ; first segment of posterior tarsi as long as the two 

 following segments together ; claws appendiculate. 



As in X. orientalis, the males have the first segment of the tarsi 

 dilated. 



Length, 6-7 mm. 



Madras : Madura ; Nilgiri Hills (G. F. Hampson, H. L. An- 

 drewes) ; Ootacamund (Champion Coll., ex Tomlin). The example 

 from Ootacamund has bronzy reflections and the pronotal punc- 

 tures are extremely fine. 



Type in the British Museum.
