bordered on each side with light granules bearing long, dark hairs,

 spine, lateral edges not produced; style somewhat like utnitu but more 

 curved, broader at apex and with the apical, inner corner produced 

 into a long, narrow process with rounded apex.

9 Vertex slightly less than one and a half times the length of the 

 pronotum (1.4 to 1). Yellowish brown, the keels of vertex, pronotum 

 and scutellum finely bordered with black; antenna with a dark ring 

 on each segment; dorsum of abdomen and ovipositor fuscous; tegmina 

 like (inihoiii('ii.''<is but lighter in color and the hyaline marks more ex- 

 tensive. ^ Like the female, but marks on tegmina not so well de- 

 fined. 



Male pygophor with a small medio-ventral spine and a small spine 

 from the latero-ventral edges; styles narrow and curved, the apices 

 twisted half a turn, a small keel along the basal third; besides the 

 penis and guide there is a long, thin spine from the ventral left side 

 of the anal segment. This species approaches dri/ns in the shape of 

 the male genitalia.

Vertex and pronotum of equal length. Yellowish brown; vertex 

 pronotum and scutellum with keels finely bordered with dark brown, 

 especially the median keels: genae beneath eyes darker, two faint 

 rings on second joint of antenna. Tegmina very like amhoinensis, with 

 the clear hyaline spaces larger, the black spots on radia, media and 

 cubitus larger and plainer and the granulations along nerves white. 

 Male pygophor with a small, medio-ventral spine, the lateral edges 

 not produced into spines, the styles somewhat like aiiihoinensis, but 

 broader and more truncate at apex, with the inner corner developed 

 into a long, narrow, roundly-tipped process.

Tliis is evidently allied to clegans, bnt as T have no descrip-
