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 geometric^ Waterh. from Surigao, Surigao, Mindanao. 

 The specimens before me agree well with Westwood's 2 figure of 

 this species. 



Doliops curcuUonoides 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.
