 last ventral segment of the abdomen of the female longer than broad, with a 

 median apical angulation projecting between the lower valves of the ovipositor, 

 and on each side of this median angle there are emarginations forming a flattened 

 triangular lobe on each side, overlying the lateral apophystegal plates.

Drymadusa mokanshanensis, n. sp. (Tettigonidae, Decticinae). 



Description, male and female. Color almost uniformly yellowish green, 

 probably green in life. Head as broad as the pronotum; fastigum of the vertex 

 narrower than the basal segment of the antennae, from a front view triangular, 

 the narrow point touching the fastigum of the front; basal segment of the anten- 

 nae very broad, the second intermediate between the basal and the succeeding 

 ones, which are cylindrical and very gradually growing smaller towards the tip 

 of the antenna; the ends are broken from the antennae of the only two specimens 

 known; eyes moderately protuberant, semicircular and brown in color. Pro- 

 notum with lateral carina roundly present only on the metanotum, where the 

 disk is flat, the rest being rounded, the anterior margin truncate, the posterior 

 margin broadly rounded; lateral lobes about as high as broad, the lower margin 

 inclined anteriorly, the posterior-inferior angle rounded, the humeral sinus 

 shallow; prosternal spines long and sharp; meso- and metasternal lobes pointed, 

 the first more than twice as long as basally broad, the latter scarcely longer than 

 broad. Abdomen plump, slightly compressed; supraanal plate ot male with an 

 apical u-shaped notch, the resulting points triangular, that of the female small, 

 triangular and dorsally sulcate, with a black spot situated mesially; cerci of male 

 sub-cylindrical, tapering, apically gently incurved, the whole five or six times as 

 long as the basal width, a prominent broad triangular tooth situated on the 

 inner side at about the basal fourth, the tip of this tooth being black, sharp and 

 decurved; cerci of female simple, cylindrical, gradually tapering to a point and 

 five or six times as long as basally broad; subgenital plate ot male forming a long 

 hollow, perpendicular sided scoop, verntrally concave with a low median carinae 

 and more prominent margins, the tip triangularly notched mesially and bearing 

 a pair of simple cylindrical tapering styles about six times as long as the basal 

 width; subgenital plate of the female much smaller than that of the male, flat 

 below, the apex broadly notched and turned outward so as to form a diagonal 

 lateral furrow; ovipositor not quite three-fourths as long as the posterior femora, 

 gently decurved and with the tip diagonally truncate. Legs slender; fore tibiae 

 with four long dorsal spines on the outer margin in the male and three in the 

 female; middle tibiae with several dorsal spines on each margin in both sr\is; 

 hind tibiae with many dorsal spines, all of the tibiae being armed below on both
