NYSIXA. 153 



159. Nyphasia pascoei, Lacord. Gen. CoUopt. viii, p. 309 (18G9). 



1'ulvous red, with the elytra green, 

 the antennae and legs (the stalks of 

 the femora excepted) nearly black ; 

 body beneath and legs glossy, upper 

 surface opaque. Scutellum acute, 

 but not prolonged, at the apex. 

 Elytra closely punctured, sharply 

 rounded and unarmed at the apex, 

 each with a small sharp tubercle at 

 the extreme base. 



Length 14-17 ; breadth 3g-4| inm. 



Hub. Burma; Siam. 



This species is very closely allied 

 to N. fusdpennis ; almost the only 

 Fig. 61. NypJuuia peacoei, difference is in the colour of the 

 Lacord., cf. x . elytra, which is distinctly green in 



the one, brown in the other. 



Genus NYSINA, g. n. 



Type, .A 7 , orientalis, White. 



Range. Assam and Upper Burma. 



Nearly allied to Nyphasia, Pasc., with which it agrees in tie 

 structure of the antennae and legs ; also, like that genus, it has 

 the acetabula of the middle coxae shut off from the epimera by a 

 prolongation of the antero-lateral angles of the metastemum. It 

 differs as follows : Antennal supports separated by a moderately 

 broad channel, so as not to form an almost continuous ridge 

 between the antennae. Prothorax distinctly longer than broad, 

 the sides scarcely rounded and not at all tuberculate, the disc 

 rugose-punctate. Elytra somewhat depressed along the middle, 

 truncate at the apex. Intercoxal process of prosternum less 

 dilated posteriorly, not meeting the epimera.

 Longic. i, p. 110 (1853); Lacord. (Nyphasia?) Gen. Coleopt. 

 viii, p. 309 (1869). 



Testaceous red ; antennae, legs and sides of breast black ; glossy 

 above as well as beneath. Head slightly rugose above between the 

 eyes, marked in front with oblique impressions which enclose a 

 small triangular area. Antennae much longer than the body in 

 the c?, a little longer than it in the $ ; third, fourth and fifth 

 joints with a distinct posterior spine at the apex, third canaliculate 

 above in the tf Prothorax about one-fourth longer than broad, 

 a little narrower in front than at the base ; the disc slightly 

 depressed, rugosely punctured. Elytra densely punctate near 

 the base, less densely posteriorly ; the surface sparsely setose, 

 and clothed with a faint pubescence ; apices somewhat obliquely
