Synopsis of the species of Trobolophya. 



a 1 . Intraocular portion of vertex, on median line, less than one-third length 

 of anteocular; viewed from side, lateral margin of vertex highly 

 arched at base; outer anteapical cell long and narrow, inner ante- 

 apical three times as long as broad (fig. 1, b) tegmina transversely 



banded melichari sp. nov. 



a*. Intraocular portion of vertex, on median line, about as long as ante- 

 ocular; viewed from side, lateral margin of vertex not so highly 

 arched at base; outer anteapical cell broad, inner little longer than 

 broad (fig. 1, a) ; tegmina never transversely banded. 

 b\ Angle between lateral margins of vertex and front, as viewed from 

 side, more than a right angle, and with the black spot roundish, 

 not reaching eye. 

 c l . Clypeus, in side view, strongly raised above the level of the front. 



penangensis sp. nov. 

 c\ Clypeus, in side view, not or very little raised above level of front. 

 cF. Lateral spot of vertex large; veins of tegmina fuscopiceous. 



jacobsoni Mel. 

 (P. Lateral spot of vertex small; veins of tegmina piceous black. 



montana sp. nov. 



b 2 . Angle between lateral margins of vertex and front, as viewed from 



side, a right angle or less, and with the black spot in the form 



of a large band, narrowing eyeward, and nearly or quite reaching 



eye. 



c\ Vertex about as long as broad at base; smaller, paler species with 



dark fuscous veins philippinensis sp. nov. 



c\ Vertex distinctly longer than broad at base; larger, dark green 

 species with piceous black veins - benguetensis sp. nov. 



Trobolophya melichari sp. nov.- Fig. 2, a, b.' 



Female. — Length, 5 millimeters. Pale greenish, legs stramin- 

 eous, becoming entirely stramin- 

 eous with a darker scutellum in 

 drying. The lateral black marks 

 on head show through on vertex 

 as two parallel lateral lines on 

 apical half and as black spots at 

 basal angles. Tegmina hyaline, 

 veins fuscous; a narrow, irregu- 

 lar, curved, smoky band passes 

 from stigma to near apex of 

 clavus.
