pronotum 6, exposed length of tegmen 6.3, exposed width of tegmen 

 3.8, length of cephalic femur 7.2, length of caudal femur 15.3 mm. 

 The type of this handsome little insect is unique. 



Anthracites apoensis new species. Plate XVIII, figures 3 and 4. 



Closely resembling A. zebra, described above, in size and pale 

 coloration, the present species may be readily distinguished by 

 its pale face, more extensively and differently marked pronotum 

 and abdomen, more abbreviated tegmina and by striking male 

 genitalic differences. 



Type : d" ; Mount Apo, Mindanao, Philippine Islands. June and 

 July. (E. A. Mearns.) [United States National Museum.] 



Agrees closely with zebra, except as follows. Fastigium of vertex 

 produced in a straight, very slenderly conical projection, its apex 

 very sharply rounded, almost aciculate. Tegmina greatly re- 

 duced, much shorter than pronotum, with distal margin very 

 broadly convex; stridulating field fully developed, but in normal 

 position wholly concealed by pronotum. Ultimate tergite broadly 

 and weakly concave disto-mesad, the deflexed supra-anal plate 

 oval, with a broad medio-longitudinal sulcus. Cerci very heavy 

 and short, broader than long, strongly inflated conical with dorso- 

 internal portion sublamellate and produced distad slightly beyond 

 apex proper, armed with a stout, feebly curved spine, directed 

 mesad; ventro-internally with a weakly incurved, very slenderly 

 cylindrical process, directed caudad and armed at apex with a 

 small spine, directed mesad and immediately below the dorsal 

 spine; between these the internal surface of the cercus is flattened. 

 Lower podical plates chitinized along dorsal margins, terminating 

 in a flattened, uncinate spine. Subgenital plate flattened, lateral 

 portions narrowly reflexed, then curled outward, so that the lateral 

 margins themselves are seen from below to be weakly convex con- 

 vergent to the briefly produced latero-caudal apices; very broadly 

 and deeply U-emarginate distad, the narrow lateral apices thus 

 formed bearing a small, apical, socketed style, with an internal 

 tooth of equal size, directed meso-dorsad. Femoral genicular 

 lobes as follows; cephalic internal bluntly triangular-produced, 

 median internal less strongly so, cephalic and median external 

 rounded, caudal external and internal bispinose. Ventral femoral 

 margins armed as follows, (in the pair at hand). Cephalic internal 

 5 to 6, cephalic external 5 to 6, median internal 1 to 2 (proximad), 

 median external 5 to 6, caudal internal 1 to 1, caudal external 4 to 7. 



Allotype: 9 ; same data as type. [United States National 

 Museum.] 



Agrees closely with male, differing as follows. Size somewhat 

 larger. Pronotum with caudal portion of disk decidedly shorter 

 and caudal margin more broadly convex. Ovipositor moderately 

 elongate, gradually tapering to acute apex, unarmed, evenly and
