for instance, Allopezus and Bolitrum. These, of course, do not 
lend themselves to zodgeographical study. By far the greater 
number of genera is represented only on the Sunda Islands, or 
possibly in the interior of India, Formosa, and Ceylon. These 
are Bolitoxenus, Leiochrodes, Setenis, Encyalesthus, Catapiestus, 
Artactes, Scotaeus , Pseudeumolpus, Platycrepis, Eucyrtus, Sima- 
lura, Hemicera, Psydus , Camarimena, Pseudonautes, Gauromaia, 
Dietysus, and Aediotorix. There remains a considerable num- 
ber of genera the species of which extend over a wider region. 
These genera, to which belong Mesomorphus, Bradymerus, 
Byrsax, Ceropria, Cossyphus, and Lyprops, extend partially 
from Africa to Australia. Scleron finds here its most easterly 
extension, Cnemodasus its most westerly. 
Only two genera fall entirely beyond these limits. As to the 
first one, Ethas, I doubt that it occurs in the Philippines ; despite 
exhausted search in the Islands it has not been found again since 
Eschscholtz’s time. It is possible that the habitat was incor- 
rectly reported and that the animals in question were found in 
India, where it occurs. Such an oversight can easily be under- 
stood when we consider that Kotzebue in his journey around the 
world touched many different regions. The second genus, 
Leptoscapha, I have discussed elsewhere. 
The foregoing remarks lead to the conclusion that the fauna 
of the Philippines must belong to the Indo-Malayan region. 
I am greatly indebted to Professor Baker, whose untiring 
activity as a collector made possible the preparation of this 
paper, and who most generously presented to me single speci- 
mens for my own collection. To express to him here my hearty 
thanks is an agreeable duty. Further, several new species were 
found in the museums of Stettin, Dresden, and Hamburg, as well 
as in my own collection. I am also greatly indebted to Mr. P. 
Timm, member of the Chamber of Audits in Zoppot, who not 
only presented me with several species from his fine collection 
but also, by means of excellent photographs taken by him for me 
at the expenditure of much time, enhanced the value of this 
work not a little . 8
