PHILIPPINE TENEBRIONID^, II J

The great activity of Prof. C. F. Baker, as a collector on many
of the islands comprising the Philippine Archipelago, has resulted
in bringing so much new material in the Tenebrionidse to the
attention of science that it is believed worth while to make this
material the subject of a special paper. I regret that I cannot,
with the Philippine material collected up to the present, comply
with Professor Baker's request to make a synopsis of the Phil-
ippine Tenebrionidse. The fact that this zealous collector has
succeeded in the short space of three years 2 in bringing together
so large a number of new species demonstrates that it would be
premature to undertake this task at present; very much more
new material will surely be found when the mountainous and in-
accessible parts of the Islands, especially those that are infre-
quently visited, shall have been explored. It is especially neces-
sary, for zoogeographical reasons, that the more remote islands
be explored— that is, such as lie near other faunal regions— in
order to determine to what extent the forms from those regions
intergrade with those of our own. Furthermore, systematic
work on Indo-Malayan Tenebrionidse is still very obscure and
cannot be attempted with material from a restricted faunal area.
As we now have more than one hundred fifty species of Tene-
brionidae a fairly clear idea can be formed of the Philippine
tenebrionid fauna. Evidently we are here dealing with a pure
Indo-Malayan fauna. Naturally, there is no lack of genera
that are restricted to the Philippines. Where such is the case
the nearest relationship must be sought, almost without ex-
ception, on the neighboring islands. To these endemic genera
belong Oedemutes, Pseudostrongylium, Aptereucyrtus, Pseuda-
bax, and Lophocnemis. Only a few genera stand entirely
isolated, no related genera being found in other faunal regions ;
