genera and species of Galerucidce. 31 



Head triangular, antennae slender, nearly equal to the l)ody in 

 length; the 2nd joint short, the 3rd rather longer, the 4th equal in 

 length to the preceding two united. Thorax transverse; sides 

 slightly rounded ; upper surface minutely punctured ; middle disk 

 transversely sulcate, the sulcation more deeply excavated on either 

 side. Elytra mmutely punctured, each elytron narrowly edged 

 with black. 



Nadrana hella. 



Ovata, convexa, nigi-a, nitida, anteunis flavis, basi nigro-piceis ; 

 thorace convexo, laevi, fere impunctato, elytris lievibus, tenuissime 

 puuctatis, apice nigris. 



Var. A. Elytris totis nigris. Long. 4| lin. 



Hah. Malacca, Tringarnee, Sumatra. Var. A. Singa- 

 pore {Wallace). 



Thorax broader than long, sides rounded; convex, remotely 

 impressed with very fine punctu.res, visible only under a lens. 

 Elytra oblong-ovate, convex, rather more closely but not more 

 strongly punctured than the thorax. 



The absence of the transverse sulcation of the thorax 

 will at once separate this species from N. ixdlidicornis. 



Prasyptera nitidipennis. 



Oblongo-ovata, postice paullo ampliata, convexa, flava, nitida, 

 vertice, labro, antennis, tibiis apice, tarsis, abdominisque macuhs, 

 iiigris, scutello pectoreque nigro-piceis; thorace transverse, laevi, 

 utrinque obsolete foveolato ; elytris oblongis, crebre punctatis, 

 viiidi-aeneis. Long. 4 lin. 



Hah. Mysol {Wallace) ; a single specimen. 



Antennae slender, the 2nd joint very short, the 3rd twice its 

 length, its base fulvous. Thorax nearly twice as broad as long ; 

 sides nearly straight and parallel behind the middle, slightly 

 rounded and converging anteriorly; upper surface transversely 

 convex, smooth, impunctate, faintly foveolate on either side. Elytra 

 rather closely and distinctly punctured ; on the disk of each elytron 

 are visible two or three faintly-raised longitudinal lines. 



Separated from P. Haroldi by the different coloration 

 of the head, by the narrower thorax, and by the brighter- 

 coloured, more strongly punctured elytra.
