convexo, opaco; metasterni lateribus late confertim ruguloso- 
punctatis, basi utrinque punctis nonnullis impressa. 
Long. 21 lin. 
This species is very close to P. Salamonis, Kaup (Berl. ent. 
Zeit. xv. p. 389), but a little smaller. Labrum beset with 
reddish hairs, sparingly and strongly punctured, deepl 
emarginate, the left lobe a little the longer. Middle of the 
epistoma considerably produced forwards, with a deep quad- 
rangular emargination. ‘Thorax moderately convex, smooth, 
with scarcely any trace of the middle line; the later al i impres- 
sion is oblique and not very deep, smooth; at the anterior 
angles there are a few punctures. Llytra with the striz 
rather deeply impressed ; the punctures in the sutural stria 
are scarcely visible, but in each stria the punctures are 
more distinct as the sides are approached; the © punc- 
tures in the lateral striz are deep, very close together, and 
transverse; in P. Salamonis these punctures are scarcely 
transverse, and are more distinctly separated from each other. 
The middle portion of the gula is smooth, semicircular in 
outline, gently convex, slightly opaque on each side, not im- 
pressed on each side of the base, as it is in P, Salamonis. 
The prosternal process is somewhat dull posteriorly, sub- 
parallel, moderately convex, and not flattened at the apex, as 
it is in P. Salamonis. The sides of the metasternum are 
densely and finely rugulose and opaque, and on each side of 
the base there are some rather strong punctures as in P 
Salamonis. 
A single example. 
Pecilopharis truncatipennis, Ritsema. 
A single specimen. ‘This species is described (Notes 
Leyden Mus. 11. 1881, p. 1) trom a male from the Aru 
Islands. 
The following more or less widely distributed species were 
also met with :—Hupholus Linnei, Th. (1); nee granu- 
latus, Fabr. (2) ; Sphenophorus obscurus, Boisd. (1) ; Chloro- 
phanus annularis, Fabr. (1) 5 Aulacophora rubrozonata, Boisd. 
(1). Alsoa single specimen of the genus Praonetha which I 
am unable to determine.
