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 Tenebrionide 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 Tenebrionide. The fact that this zealous collector has 
succeeded in the short space of three years ? 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 zodgeographical 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 Tenebrionide 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- 
brionide 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;
