MERISMODERUS HAMATICORNIS. 3 



dered of high interest. Although mj new species is doubt- 

 less congeneric with M. Bensoni Westw., still there are 

 great dififerences between both; besides the coloration, the 

 most striking characters of hamaticornis are, the little hook 

 into which the lower inner edge of the club is prolonged 

 and the short and strongly transverse head. A unique spe- 

 cimen has been forwarded (together with a specimen of 

 the hardly known Lehiode^'us Percheronii Westw.) to Mr. 

 E. W. Janson by Mr. Carl Bock , who took them in Su- 

 matra but unfortunately did not mention a more peculiar 

 locality. 



Platyrhopalus macrophyllus, v. d. Poll. 



Nitidus, piceus. Clava antennarum magna, lata, multo 

 depressa , apice angulata , margine postica in denies duos 

 pervalidos producta et ante hasin nonnihil obtuse lobata. La- 

 tera protJioracis antice subangulata, valde obtusata. 



PL vexillifero Westw., multo ajjinis sed clava valde de- 

 pressa hand in /lata , cuius dentes postici validiores et magis 

 trianguliformes , denticulusque suhbasalis haud acutus sed valde 

 obtusatus y et prothorace antice subangulato haud gradatim 

 rotundato apicem versus, discrepat. 



Long. 7^/2 mm. 



Habitat: Temanggoeng, Central Java. 



Very much like Platyrhopalus ve.villifer Westw., of which 

 the unique type specimen of Mr. E. W. Janson's collection , 

 is now in my possession. Somewhat more robust in all 

 its proportions , almost of the same piceous colour , but 

 the antennary club, elytral margins, undersurface and legs 

 slightly darker. The antennary club affords the best cha- 

 racters to separate both species, being larger and depres- 

 sed instead of inflated, and differing also in outline, the 

 apex more triangular, 'the two enormous teeth formed by 

 the hinder margin much stouter at the base and of course 

 more triangular-shaped , on the contrary the small tooth 

 near the base hardly indicated by a broadly rounded pro-
