is represented or replaced on the smaller islands by a nearly 
related species or subspecies. In the case of the species, the 
close relation to the one from Mindanao or to that from the 
smaller islands is clearly observable, the characters based on 
the sculptural structure and the colored markings being similar 
to a greater or less degree, but sufficiently distinct to be con- 
sidered as a separate species. 
Among the species collected are a few long-known species, 
originally described as from the “Manillas” or just Philippines. 
The following are worth mentioning: 
Doliops geometrica Waterh. from Surigao, Surigao, Mindanao. 
The specimens before me agree well with Westwood’s 2 figure of 
this species. 
Doliops curculionoides Waterh. from the same locality. 
Euchirus dupontianus Burm. This species I recorded before 
from Baganga, Davao, Mindanao. Now Surigao and Bucas Is- 
land may be added. A male from the last-mentioned locality has 
the black lateral stripes on the elytra very faintly pronounced 
except near the shoulder where the same are expanded and 
spotlike. Length, 74 millimeters; width at shoulder, 32; length 
of anterior femur, 48 ; length of anterior tibia, 48. 
Again, the question of mimicry suggests itself due to the very 
apparent superficial aspect on account of similarity in markings 
and patterns among a large number of species herein described.
