The head and pronotum in this insect are not as decidedly im- 

 presso-punctate as in 0. intermedins Redtenbacher. 



Length of body 36, greatest width of head 8.2, length of pro- 

 notum 9.5, length of tegmen 11.3, width of tegmen 5, length of 

 cephalic femur 10.1, length of caudal femur 18.7, length of ovipositor 

 17.5, greatest width of ovipositor 2.7 mm.

Redtenbacher does not comment on the shortness of the limbs 

 and the numerous short, stiff hairs there found. The species ap- 

 parently has no close allies. 



Length of body 21.5, length of pronotum 5.7, caudal width of 

 pronotal disk 4, length of tegmen 31, width of tegmen 5, length of 

 cephalic femur 4.8, length of caudal femur 10.7, length of ovipositor 

 10.2, greatest width of ovipositor 2.7 mm. 



Anthracites major new species. Plate XVII, figure 19. 



The large size and black body but almost uniformly pale limbs 

 of this insect distinguish it from its nearest allies. Agreeing more 

 closely with A. nitidus Redtenbacher in other features of colora- 

 tion, the male genitalia are seen to be very different, while the 

 limb spination is closer to that described for A. geniculates Dohrn. 

 All of these species are known only from the Island of Mindanao. 



Type: d 1 ; Surigao, Mindanao, Philippine Islands. (From C. F. 

 Baker.) [Hebard Collection, Type no. 836.] 



Size large, form moderately robust, for the genus. Fastigium 

 of vertex produced in a straight, very slenderly conical projection, 

 its apex sharply rounded. Face smooth and shining, showing a 

 few subobsolete impressions. Tegmina greatly reduced, much 

 shorter than pronotum, with distal margin very broadly convex; 

 stridulating field fully developed but in normal position wholly 

 concealed by the pronotum. Cerci very short and heavy, weakly 

 curved inward, with a heavy dorso-distal and a decidedly heavier 

 ventro-distal tooth, these curved and directed strongly inward.
