the scaling, and consisting of shallow, closely set punctures ; 
a single pair of punctures shows through the scaling in the 
middle of the disk, and sometimes a more distant pair behind ~ 
the middle. lytra with the basal margin simple and almost 
straight; those of the 2 broad, almost parallel-sided to 
beyond the middle, rather sharply acuminate behind and 
separately pointed ; those of the ¢ narrower, much less acute 
behind and jointly rounded at the apex; very shallowly 
punctate-striate, the number of the strize being 14, owing to 
the intercalation of two striae between the normal fourth 
and fifth or fifth and sixth, the additional strize uniting and 
ceasing a little behind the middle ; the intervals flat, with 
coriaceous sculpturing, which is quite hidden by the scaling, 
and with short, recumbent, flattened, white sete.

JAMAICA (A. HZ. Ritchie). 
P. opalescens, Oliv., P. litus, Germ., and P. azurescens, 
Gyl., may all be distinguished from this species by the fact 
that they have the base of each elytron distinctly lobed and 
the external angle projecting forwards. Of the remaining 
described species, P. distans, Horn, is the nearest ally to 
P. citri, but differs as follows:—The rostrum, as seen 
laterally, is deeper, its dorsal outline being strongly convex ; 
the gular emargination of the prosternum is very much 
shallower ; the elytra are narrower and have only 12 strie. 
P. psittacus, Oliv., differs in having the space between the 
apices of the scrobes markedly narrower than the forehead, 
the distal joints of the funicle not longer than broad, &e. 
Mr. Ritchie states that this species was found on citrus- 
trees. 
Pachneus marmoratus, sp. n. 
@. Colour piceous, with creamy-white scaling variegated 
with glittering pale green markings as follows :—The pro- 
thorax with two broad oblique discal stripes, which unite 
broadly in front; the elytra with five or six narrow, ex- 
tremely irregular or broken, transverse bands, and a narrow 
sutural and broader lateral stripe; the head, rostrum, and 
legs with metallic coppery scaling. 
Head with the vertex rather prominent, the forehead with 
a bare median costa extending behind the eyes and bearing a 
large central fovea. tostrum longer than broad, parallel- 
sided, the dorsal outline as in P. cétr¢, but the depth propor- 
tionately less ; the dorsum with a bare impunctate costa and 
a shallow longitudinal impression on each side of it, but no 
lateral costa, the space between the apices of the scrobes as
