CANAL ZONE AND THE PHILIPPINES 1

The following two new species of paussid beetles are described 
here for reference in other connections. 
HomoptePus (s. s.) subcordatus n. sp. 
Fig. 1 
Form average in genus; castaneous, moderately shining; most 
of head, pronotum, and elytra rather closely punctate with punctures 
of moderate size, but not obviously pubescent (some of the punc- 
tures have very short hairs which scarcely rise above the level of 
the body surface). Head across eyes (not including post-ocular 
tubercles) about 5/6 as wide as prothorax; post-ocular tubercles 
prominent; occiput only vaguely swollen; front concave, with a pair 
of deeper impressions within the concavity; antennae as figured, 
the flattened segments irregularly granulate above, more closely so 
on the anterior sides of the transverse segments and around the 
apical segment, the granules bearing short, inconspicuous hairs ; 
mouth-parts normal for genus. Prothorax as figured, wide, with 
sides sinuate before base ; disk convex, slightly swollen on each side, 
rather deeply longitudinally impressed at middle ; disk also vaguely 
impressed or flattened across base and apex; lateral margins un- 
usually broad, running into moderate baso-lateral impressions. 
Elytra rather elongate (in genus), about % wider than prothorax, 
subparallel, with outer sides very weakly arcuate. Femora and 
tibiae only moderately wide in genus. Pygidium closely punctate; 
preceding dorsal abdominal segment more finely and less closely so. 
Male copulatory organs as figured. Length to apex of elytra, about 
8 mm. ; width , about 3 mm. or slightly more (both specimens too 
warped for accurate measurement of width).
