described from Tonkin, but no characters warranting generic 

 separation can be determined after close comparison with the 

 description of that species. 



The fully developed tegmina give mindanensis a much stronger 

 resemblance to species of the genus Salomona. It is, however, 

 easily distinguished from that genus by the unspined prosternum, 

 specialized vertex, absence of a spine on the median coxae, 76 

 ovipositor of the type found in Oxylakis and other less important 

 features. 



The fully developed organs of flight, much shorter vertex, very 

 weakly impresso-punctate face, pronotum which is produced caudad 

 with humeral sinus distinct, apparently different femoral armament 

 and coloration quickly separate 'mindanensis from brongniarti. 



Type: 9 ; Surigao, Mindanao, Philippine Islands. (From C. F. 

 Baker.) [Hebard Collection, Type no. 841.] 



Size medium, form robust; much as in the smaller heavier species 

 of Salomona. Head very large and broad, occiput moderately 

 impresso-punctate, face shallowly impresso-punctate, genae more 

 strongly so and irregularly rugulose. Vertex produced in a slender 

 conical fastigium, slightly longer than its proximal width, with apex 

 rounded; dorsal surface with low, heavy basal tooth, then a blunt 

 tubercle followed by two transverse sulci. Pronotum much as in 

 Salomona, but with ventro-caudal portions of lateral lobes bent 

 outward; disk flattened, rugulose, with a slightly impressed area 

 at the weakly indicated principal sulcus, caudal portion slightly 

 produced with caudal margin truncate; lateral lobes rugose with 

 sulci distinct, ventral margin oblique declivent caudad, weakly 

 obtuse-angulate-emarginate cephalad, ventro-caudal portions lightly 

 and roundly produced so that a broad humeral sinus is indicated. 

 Tegmina and wings extending to near apex of ovipositor. Ovi- 

 positor unarmed, weakly curved dorsad, broadening slightly beyond 

 base, then narrowing gradually to the rounded apex. Subgenital 

 plate short, with caudal margin truncate. Genicular lobes of 

 femora unispinose, except the external of the cephalic and median 

 femora, which are roundly produced. Cephalic and median femora 

 moderately heavy, their ventral margins distad showing a broad 

 and weak but appreciable concavity. Ventro-internal margin of 

 cephalic femora armed with a large spine preceded by (1 to 3) very 

 small spines, followed by (2 to 3) small spines and then a larger 

 spine. Ventro-external margin of median femora armed with 

 three large spines, of which the median is the largest, with (2 or 3) 

 small spines in the intervals between. Ventro-external margin of 



76 In all species of the genus Salomona before us, both the cephalic and median 

 coxae bear a stout spine, those of the median coxae being shorter and more 

 uncinate.
