Mindanao, Surigao, Iron Deposit (my collector). Types in 

 my collection. This species was found feeding on Ixonanthes 

 longipedunculata Merr., also a new species, and a genus new to 

 the Philippine flora. 



Several specimens of this species were collected on Biliran 

 Island, near Leyte, by my friend R. C. McGregor. Since R. 

 merrilli is the first species of this genus to become known from 

 the Philippine Islands, I wish to call attention to Heller's 5 re- 

 marks concerning the range or locality distribution and expan- 

 sion of Rhinoscapha in comparison with the expansion of the 

 pachyrrhynchids. 



Alcides figuratus sp. nov. Plate I, fig. 15. 



Subcylindrical, black, with creamy white bands. Related to 

 A. catanduanensis Schultze. Rostrum sparsely and irregularly 

 punctured in the basal half. Front with a well-pronounced de- 

 pression. Vertex of head very finely punctured. Prothorax 

 strongly coriaceous. A broad anterior submarginal band, inter- 

 rupted at the middle, extending to the prosternum; another 

 posterior marginal band, also interrupted at the middle. Elytra 

 striate-punctate, the punctures rather coarse, particularly at 

 the basal half. A combination of bands forming the figure A 

 extending from the suture behind the scuteilum to before the 

 middle and to the margin. Another crossband beyond the 

 middle reaching from one lateral margin to the other, a short 

 branch extending forward at the suture. Apical triangle with a 

 V-shaped marking. Legs finely and sparsely punctured. 



Length, 15.5 millimeters, without rostrum; width, 5.8. 



Dinagat Island (my collector). Type in my collection. • 



Another nearly related species is the following: 



Alcides adversarius sp. nov. Plate I, fig. 14. 



Subcylindrical, shiny black, with creamy white bands. Pro- 

 thorax irregularly punctured, the punctation toward the base and 

 lateral margins gradually coarser and confluent. An anterior 

 submarginal oblong spot laterally, and a band at the posterior 

 margin, interrupted at the middle, expanded and spotlike dis- 

 eally, extending to the lateral margin. Elytra striate-punctate, 

 the punctures much finer than in A. figuratus. At the 

 basal half a crossband, which is spotlike and expanded at the 

 suture and extends in a curve to the lateral margins. Beyond 

 the middle another crossband, interrupted at the suture, ex-
