This interesting species is known from the described pair. 



Phaula galeata new species. Plate XIII, figures 8 and 9. 



This species belongs to the second section of the genus, as 

 recognized by Brunner, in which the first branch of the median 

 vein of the tegmina is forked. This should be noted as a feature 

 of convergence toward the type characteristic of the genus Elbenia. 

 It would appear probable that in this section of the genus several 

 distinct generic units are involved and the present species may 

 require generic separation when the group is comprehensively 

 studied. At the present time insufficient material is at hand for 

 this to be accomplished, though we feel justified in separating, on 

 page 150, one of the units included by Brunner. 



The remarkably crested and undivided anal tergite of the male, 

 readily separates it from males of the species of apparently nearest 

 affinity, the Bornean P. gracilis Brunner. 



Type: d\ Davao, Mindanao, Philippine Islands. (From C. F. 

 Baker.) [Hebard Collection, Type no. 796.] 



Vertex narrowly V-shaped and sulcate to near apex, the lateral 

 margins parallel in distal portion as in P. phaneropteroides Brunner. 

 Pronotum with surface smooth, the lateral lobes very slightly 

 wider than deep. Tegmina and wings fully developed. Tegmina 

 with costal margin of stridulating area convex, not produced at 

 stridulating vein; median vein with first branch forked slightly 

 beyond median point and weakly oblique, the median vein with a 

 second undivided oblique branch distad; ulnar vein reaching 

 sutural margin at end of its proximal two-thirds. Anal tergite 

 produced mesad in a vertical lobe, this lobe higher than long, its 

 dorsal and ventral margins moderately divergent to its broadfy 

 convex distal margin, the dorso-distal angle bluntly rounded, the 

 ventro-distal angle delicately lipped. Cercus cylindrical, tapered 

 and curving evenly inward to the irregularly enlarged apex, which 

 is produced in a long, weakly sigmoid tooth. These organs reach 

 to the base of the produced lobe of the anal tergite. Subgenital 

 plate small, triangular, medio -longitudinally cleft to its base. 

 This plate suggests the usual triangular type found in females 

 rather than the type developed in males of any species we can 

 recall. Ventral femoral margins armed with very small spines as 

 follows. Cephalic internal 5, cephalic external 0, median internal 

 and 1, median external 6 and 7, caudal internal 3 and 5, caudal 

 external 7 and 7.
