In this paper I wish to make known some species of Coleoptera 

 from Surigao Province, Mindanao, and from the small islands 

 Dinagat, Siargao, and Bucas Grande located off the northeastern 

 shores of Mindanao. Comparatively little entomological col- 

 lecting has been done in Mindanao and the smaller islands near 

 it. The material herein described was collected by two of the 

 Bureau of Science botanical collectors and my entomological 

 collector, during the months of April, May, and June, 1919. The 

 principal collecting was carried on in the vicinity of the town of 

 Surigao. Several trips were made to a locality hereinafter called 

 Iron Deposit. This region has been known for some time as 

 a remarkable locality, geologically as well as botanically. It 

 is located some 40 kilometers southeast of the town of Surigao 

 near the settlement of Taganito. The soil at that locality is 

 heavily charged with iron oxide, and in the near vicinity are also 

 found deposits of coal, iron, 1 copper, and gold. Two remark- 

 able pitcher plants are found there abundantly, at low and 

 medium altitudes, these being Nepenthes truncata Macf. and N. 

 me7'rilliana Macf., both being among the representatives of 

 the genus with the largest pitchers known; a smaller species, 

 N. alata Blanco, is also abundant. Five to six days were spent 

 on each of the islands of Dinagat, Siargao, and Bucas Grande. 

 A comparatively large number of species and specimens, con- 

 sidering the time spent there, was collected at all of the above- 

 mentioned localities, due undoubtedly to the favorable season; 

 during certain seasons of the year the last-mentioned islands 

 are almost unreachable by boats, due to their being exposed to 

 the full sweep of the monsoons across the Pacific. A very note- 

 worthy feature among a number of species from the above local- 

 ities is the fact that a species from Siargao, the larger island,
