from the posterior margin. At the anterior margin a narrow 

 band of scales, at the middle laterad a roundish scale spot, and 

 another oblong spot at the lateral margin. Elytra irregularly 

 punctured in rows. The punctation similar to that in 0. schon- 

 herri but somewhat denser. Each elytron with the following 

 spots: Two at the base, one dorsally, the other at the lateral 

 margin. At the middle a cross row of two spots, one dorsally, 

 the other laterally. An oblong spot at the lateral margin. At 

 the apical half a series of four or five spots ; one of which, dor- 

 sally, has a tendency to become bifid, and two smaller spots be- 

 tween the latter and the oblong marginal spot. A subsutural 

 spot is sometimes present, located posteriorly to the bifid spot. 

 Another spot at jthe apical triangle. Mesosternum and meta- 

 sternum with a spot laterally. Abdominal segments sparsely and 

 scatteredly setose, more pronounced in the male. Femora with 

 a scale spot near the apex, sparsely punctured and setose, tibiae 

 more pronouncedly setose. Femora of the male reaching beyond 

 the apex of the elytra. 



Male, length, 14.5 millimeters; width, 6. Female, length, 15.5 

 millimeters; width, 7. 



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

 in my collection. 



Several specimens collected on Dinagat differ from the above, 

 in as much as the punctures on the prothorax are still more con- 

 fluent, almost coriaceous; in one specimen the spots are nearly 

 absent. No specimens were collected on Siargao Island. This 

 species is easily distinguished from 0. schonherri Waterh., which 

 I received from Paracale, Ambos Camarines Province, Luzon, 

 by its smaller size, different sculpture — particularly on the pro- 

 thorax — and smaller spots. The second cross row of spots on 

 each elytron consists of only two in malayanus but three in 

 schonherri. 



From Bucas Grande Island numerous specimens were received, 

 which represent a rather distinct local form of the above species 

 and which I shall designate as 



Metapocyrtus (Orthocyrtus) subsp. atratus subsp. nov. 



Entirely glossy black, punctures on the rostrum, prothorax, 

 and elytra sparser and less pronounced. 



None of the specimens shows any trace of scales. The subsp. 

 atratus represents a parallel to Pachyrrhynchus virgatus subsp. 

 insulanus subsp. nov., together with which it was collected from 

 the same plants.
