Genus SIGNORETIA Stal 



Synopsis of species. 



Plane of vertex subhorizontal, not declivous, and not in line (profile) 



with anterior curve of pronotum; front gently convex; pronotal 



1 longitudinal 



margin of basal 



cell of clavus about three times as long on the commissure as on 

 the anal margin. 

 b 1 . Pronotal submedian longitudinal ridges crossing anterior depression 

 strong, sharply raised; intersections between thimble pits of prono- 

 tum sharp and strong; without black spots; length of female, 6 to 7 



millimeters S. malaya Stal. 



b 2 . Pronotal submedian ridges low, broad, scarcely distinguishable; in- 

 tersections between thimble pits of pronotum low, broad, and smooth ; 

 with black spots on head and pronotum; length of female, 9 milli- 



a 2 . Plane of vertex strongly declivous in line (profile) with anterior curve 

 of pronotum; front strongly swollen on apical two-thirds; pronotal 

 median carina present, at least anteriorly, the submedian longitudinal 

 ridges lacking; margin of basal cell of clavus little longer on com- 

 missure than on anal margin. 

 b\ Pronotum longer than wide; ocellus distant from eye its own diameter 

 or little more. 

 c\ Pronotal median carina broad, callose, complete; pale colored 

 throughout; median carina of vertex confined to base or wanting. 

 d 1 . Pronotal carina strongly raised anteriorly; the subapical cell 

 subequal in length to the small triangular outer apical cell: 

 head with dark spots; disk of vertex with a median carina 



basally S. carinata sp. nov. 



dr. Pronotal carina not strongly raised anteriorly; the subapical cell 

 much longer than the small triangular outer apical cell; head 

 without dark spots; disk of vertex without a median carina. 



S. tagalica Baker. 

 c 2 . Pronotal carina confined to anterior half, high and strong where 

 it crosses the anterior depression; abdomen largely black and with 

 dark markings elsewhere; median carina of vertex complete. 



S. bilineata sp. nov. 



b\ Pronotal length less than the width; ocellus distant from eye 



about twice its own diameter; pronotal median carina confined to 



anterior half; body strongly marked with black, the males much 



darker S. benguetensis sp. nov. 



Signoretia malaya Stal. 



Study of a large series of specimens of this species obtained at 

 Singapore and Penang, show that the Philippine specimens 

 reported as this species were correctly determined. 14 However,
