New Species of Galerucide. 55 
medio nigro-binotato, elytris infra basin transversim 
excavatis, fortiter punctato-striatis. Long. 44 lin. 
Hab. Malacca. A single specimen collected by Mr. 
Wallace. 
Vertex smooth, impunctate ; interocular spaces bounded 
within by a deep groove; antenne (the basal joint ex- 
cepted) pale fulvous; apices of jaws and eyes black. 
Thorax twice as broad as long; sides narrowly edged 
with black, straight and nearly parallel from the base to 
the middle, dilated and obtusely angulate just before the 
latter, thence obliquely converging to the apex, the 
anterior angles excurved ; disk minutely punctured, its 
anterior portion impressed on either side with a deep 
longitudinal sulcation, which is dilated at base and apex, 
and extends from the anterior margin nearly to the 
middle of the thorax. Scutellum obtusely truncate. 
Elytra rather broader than the thorax, narrowly oblong- 
ovate; convex, the basilar space bounded without and 
beneath by a distinct depression ; strongly punctate- 
striate, the interspaces sparingly impressed with minute 
punctures. 
Eutheca malayana. 
Anguste ovata, convexa, pallide piceo-fulva, nitida, 
antennis extrorsum oculisque nigris, thorace flavo, 
lateribus ante medium obtuse angulatis ; elytris sat 
fortiter punctato-striatis, interspatiis planis, lis ad mar- 
ginem obsolete convexis. Long. 4 lin. 
Hab. Macassar. 
Vertex smooth, impunctate; interocular spaces bounded 
within by a deep sinuate groove; antenne more than 
half the length of the body, the five outer joints, together 
with the apex of the sixth, black. Thorax more than 
twice as broad as long; sides straight and nearly parallel 
from the base to the middle, slightly produced and 
obtusely angulate just beyond the latter, thence obliquely 
converging to the apex; disk smooth, very minutely and 
somewhat sparingly punctured; on. either side in front 
is a fine distinctly punctured perpendicular groove, 
which extends downwards from the anterior margin for 
nearly half the length of the thorax, and then curves 
abruptly outwards to the lateral margin; at the base, 
placed immediately below the perpendicular grooves are 
two small fovee. Elytra oblong, convex, very faintly
