MALAYAN MEMBRACIDAE. 9 



Length 6 nun. ; width between extremities of suprahumerat 

 horns 6 mm. 



Type: female (Baker's duplicate No. 8773). 



Locality : Singapore. 



The foregoing species is close to T. auritus which Buckton 

 described as Otaris auritus from Sumatra (Buckton. Monograph 

 of the Meinbracidae, p. 429. PI. 59. figs. 1, la. 1903), but differs 

 decidedly in size and in the comparative proportions of the supra- 

 humeral horns and the posterior process. 



18. Centruchus laticornis, sp. nov. 



Eesembling the preceding species in general appearance but 

 differing in having unarmed hind trochanters which I believe is a 

 sufficient generic character to distinguish the genera Tricentrus and 

 Centruchus which are in other respects very similar. 



Body subtriangular ; suprahumeral horns broad and flat with 

 truncate tips; posterior process short and narrow; tegmina ferru- 

 ginous with faint median white band; entire body largely marked 

 with white tomentose patches. 



Head wider than long, black, rugose, finely punctate, sparingly 

 pubescent; base regularly and evenly rounded; eyes prominent, 

 brown; ocelli conspicuous, pearly, a little farther from each other 

 than from the eyes and situated well above a line passing through 

 centers of eyes ; clypeus longer than wide, trilobed at apex, extend- 

 ing well below the inferior margin of the face, tip rounded and 

 bearing long, stiff, white hairs. 



Prothorax black, finely punctate, sparingly pubescent, decorat- 

 ed with irregular white tomentose patches; metopidium much 

 broader than high; humeral angles weak, triangular, inconspicuous; 

 suprahumeral horns long, broad, flattened dorsoventrally, tips 

 squarely truncate, dorsal surface with longitudinal carina slightly 

 behind middle, horns about as far apart at bases as the width of 

 the head; median carina percurrent; posterior process short, uni- 

 formly narrow, tricarinate, largely tomentose, tip acute, extending- 

 just to the internal angles of the tegmina; scutellum broad, notched, 

 tomentose. 



Tegmina ferruginous, wrinkled, subopaque; base brown and 

 punctate ; a faint whitish band extending across the central part of 

 tegmina just below the tip of the posterior process ; veins prominent 

 and slightly nodulose in apical region. 



Undersurface of body black with white tomentose patches. 

 Legs uniformly light ferruginous brown. 



Length 6 mm. ; width between extremities of suprahumeral 

 horns 6 mm.
