foveolate; antennae dark reddish brown, second joint of funicle 
one and one-half times longer than first, the last two spheric, 
club elliptic, somewhat longer than the three preceding joints 
of funicle together; prothorax one and one-half times as broad 
as long, broadest at base, with a smooth median line and clothed 
with larger brown or black scales, the latter condensed on each 
side of disk into a black dot, and moreover with some smaller 
hornlike transparent scales which form a double median line 
in the anterior half ; scutellum roundish, sparingly setose-squa- 
mose, the base smooth in the middle; elytra broadest at base, 
there broader than prothorax, proportionately shorter, as in 
C. loripes and C. dentipes, the alternate intervals more convex, 
the punctures of striae very coarse, as broad as the intervals, 
and each filled by a scale; along the suture and on shoulders 
covered with long, adpressed scales; intervals with series of 
erect, remote setiform scales, the second with four, the fourth 
with three, the sides with two or three lineolate black spots; 
moreover here and there with aggregated bluish white hyaline 
and vesiculous scales; below very coarsely punctate, each punc- 
ture filled by a white scale, meta-episterna with only a single 
row of quadrate punctures; hind legs with a second, minute 
tooth, hind tibiae with fine carinulae. 
Roelofs 68 has described four non- American species of Coe- 
losternus as questionably of this genus, from Japan, while the 
other species, enumerated by Gemminger and Harold , 69 for the 
Oriental Region, belong mostly to the genus Lobotrachelus. I 
have before me only Coelosternus (?) electus Roelofs, deter- 
mined by D. Sharp, which is distinguished from Schonherr’s 
first section by the shorter oblong-ovate instead of cylindric 
club; but, notwithstanding this, it is best placed in this genus. 
Lacordaire 70 mentions as particularly characteristic for Cryp- 
torhynchus and Coelosternus a band of mostly golden-yellow 
bristles on the outside of the apical part of hind tibiae, such 
band being absent in C. philippinensis but present in the 
following, very closely allied species from Java: 
Coelosternus javanus sp. nov. 
C. philippinensi sp. nov. valde affinis, sed differt: squamositate 
pallidiore fere numquam maculis nigris intermixta, ad humeros 
albicante, elytris apicem versus minus attenuatis, sutura in dimi-
