Two new Species of the Genus Enoplotrupes. ot 
surface obsoletely rugose, not much difference between the 
rugosities of the head, prothorax, scutellum, and elytra. Head 
behind the horn, prothorax at the anterior margin and 
in the impressions at the side of the horn smooth, shining. 
Head with a small longitudinal carina in front of the horn, 
especially distinct in the female ; the anterior margin equally 
rounded ; a tooth on each side near the eyes, not large; the 
impression behind the horn somewhat arcuate. Prothorax 
broader than the base of the elytra, at the sides and posterior 
angles strongly rounded, not toothed at the outer margin; 
the median line behind the horn nearly obsolete. Hlytra 
broad, rounded, slightly convex, with some obsolete raised 
lines, one of which near the shoulder is a little more raised at 
its base. 
6. The horn of the head very long, curved backwards, 
that of the prothorax also long, curved towards the front, 
bifurcate, its base compressed, nearly surrounded by the 
smooth impressions; the latter are only separated by a small 
carina above the horn. The smaller the males the shorter 
are their horns, and their prothorax more resembles that of 
the female as they diminish in size. 
?. Head with a short conical horn; prothorax with an 
acute transverse carina, elevated on each side into a tooth ; 
these latter are a little larger than those at the anterior angles 
of the prothorax. The impressions on the sides of the carina 
are nearly obsolete. 
This species is principally distinguished by its uniformly 
slightly rugose upper surface in the male, by its long curved 
horns on the head and prothorax, and by the wide impres- 
sions of the prothorax. ‘The elytra are of the same size and 
form as those of /. s(nensis, Luc., but are much more rugose, 
and the raised lines are stronger. 
We have both males and females from Siam.
