Obi Island, Moluccas, 4 d\ 4 9 . 



Amboina Island, Moluccas, 33 d 1 , 18 9 , [A. N. S. P.]. 



Of the material before us, two males and three females from 

 Obi are rich green, the others brown. Both phases are represented 

 in the Amboina series, but many of the specimens are badly dis- 

 colored. 



The measurements for the Obi series are as follows. Length of 

 body d 1 62 to 69, 9 66 to 74; length of pronotum d" 9.8 to 10, 

 9 11.2 to 11.7; length of pronotal lateral lobe c? 6.3 to 6.4, 9 6.9 

 to 7.2; depth of pronotal lateral lobe <? 6.5 to 6.6, 9 7.1 to 7.4; 

 length of tegmen cf 68 to 71.5, 9 83.5 to 89; meso-distal width of 

 tegmen 46 c? 14.9 to 15.3, 9 16.8 to 18.7; length of caudal femur 

 cf 41 to 41.9, 9 47 to 48; length of ovipositor 43 to 47 mm. 



Section MECOPODI 

 Characta Iabuanae new species. Plate XVI, figure 5. 



Closely related to C. bitubeixulata Redtenbacher, the present 

 insect is distinguished by the generally smaller size; shorter teg- 

 mina, which have a greater number of oblique veins at the distal 

 margin; lateral margins of the pronotal disk, which are coarsely 

 but equally tuberculate in prozonal, mesozonal and metazonal sec- 

 tions, and auditory foramina of cephalic tibiae, which are apert, 

 the external only showing some thickening and lamellation of its 

 ventral margin. 



Type: 9 ; Labuan, British North Borneo. [Hebard Collection, 



Type no. 811.] 



Size smaller, form more stocky than in bituberculata. Vertex 

 sulcate, rounded, with strongly bifid apex distinctly narrower than 



46 These organs are curved over the dorsum proximad, so that an accurate 

 measurement of the greatest width cannot be taken.
