Metapocyrtus (Orthocyrtus) consobrinus sp. nov. Plate I, fig. 5, ? . 



Black with pale green scale markings. Related to O. mala- 

 yanus sp. nov. Rostrum densely confluently punctured. At 

 the base a broad, rather indistinct depression, with a scale spot, 

 not separated by a well-defined cross groove from the front, 

 the depression extending to the latter. Front with an indistinct 

 medial groove, scatteredly punctured, the punctures finer toward 

 the vertex. Prothorax broader than long, greatest width before 

 the middle, strongly coriaceous, with anterior and posterior sub- 

 marginal groove. A narrow band at the anterior and posterior 

 margins, interrupted at the middle. A small roundish scale spot 

 toward each lateral margin and a large oblong spot at each lateral 

 margin. Elytra punctured in irregular rows, the punctures 

 denser and much coarser than in 0. malayanus. Each elytron 

 with the following spots: Three oblong spots at the base, one 

 located dorsally, and two at the lateral margin. A cross row 

 of three spots at the middle, having a tendency to form a band ; 

 an oblong spot at the lateral margin; at the apical third three 

 spots, two of which are elongated dashes ; another slender, dash- 

 like spot subsuturally, and an oblong spot at the apical triangle. 

 Lateral margins apically sparsely setose. Underside and legs 

 irregularly sparsely punctured and rugose and sparsely setose. 



Male, length, 13.3 millimeters; width, 5.6. Female, length, 

 14.8 millimeters; width, 6.8. 



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

 my collection. 



This species is easily distinguished from 0. malayanus by its 

 smaller size and the different sculpture, particularly of the pro- 

 thorax. 



Metapocyrtus consobrinus seems to be very variable as far as 

 the spots are concerned. Among the material collected are some 

 specimens which are uniformly black. 



The males of this species, as well as of malayanus and other 

 related species of Orthocyrtus, are easily differentiated from the 

 females by the following characters : The elytra of the females 

 are longer and much more inflated dorsolateral^ than in the 

 males; since the prothorax in both sexes is relatively subequal, 

 the males show a much slenderer aspect. In species of the 

 subgenus Orthocyrtus the posterior femora of the males extend 

 beyond the apex of the elytra, whereas in the subgenus Homa-
