coloration of the antennae, pronotum and limbs, while, though of 

 the opposite sex, the tegmina are shorter and narrower and the 

 caudal femora shorter, showing a differentiation in these proportions 

 greater than we believe can be attributed to sexual differentiation. 



The present is a medium large species, in life probably of a pale 

 green coloration, the lateral margins of the pronotal disk outlined 

 in a series of brown flecks, the tegmina with brown flecks, the 

 cephalic and median femora proximo-externally splotched and 

 necked with brown and the median and caudal tibiae with a 

 proximo-external fleck of the same color. 12 



The male subgenital plate is forked to near its base and divided 

 into two strongly recurved, almost flagellate, processes, which 

 proximad are embraced by the cerci. 



Type: cf ; Davao, Mindanao, Philippine Islands. (From C. F. 



Baker.) [Hebard Collection, Type no. 785.] 



Size and form medium for the genus. Cephalic femora rather 

 strongly compressed and curved in a Phasmoid manner, lamellate 

 dorsad except in immediate proximal portion, this formed by the 

 external margin which longitudinally shows a very weak con- 

 vexity. Cephalic coxae each armed with a very small spine. 

 Foramen of cephalic tibiae conchate, deplanate dorsad and strongly 

 flattened laterad. Face to clypeal suture somewhat swollen, 

 bounded on each side by a broadly and shallowly concave area. 

 Tegmina with median vein branching mesad, this branch sending 

 two branches to the sutural margin distad. Pronotal disk with 

 surface flattened, lateral margins very broadly and evenly concave. 

 Lateral lobes of pronotum with length slightly greater than greatest 

 (caudal) depth; ventral margin horizontal, almost straight, curving 

 gently into the ventro-cephalic and ventro-caudal angles. Tegmina 

 and wings fully developed, the former with greatest width de- 



from a female from Java (Hist. Nat. Ins., Orth., p. 418, (1839).) Dohrn, recog- 

 nizing this difference, has named the species brunneri and has described very 

 briefly the male sex. That sex is seen to differ from the male of baker i in having 

 the supra-anal plate sharply acute distad, the cerci apparently more simple and 

 not embracing the subgenital plate (Stelt. Ent. Zeit., LXVII, p. 348, (1906).) 

 Unfortunately Karny overlooked this and has again renamed the species brunneri 

 (Zool. Mededeel. Rijks Mus. Nat. Hist. Leiden, V, p. 183, (1920).) It would 

 appear that Haan, describing a Javanese male as parumpunctata Serville, really 

 had that species (Verh. Nat. Gcsch. Nederl. overzee. bezitt., Zool., Ins., p. 192, 

 (1842).) If this is true, parumpunctata is a species belonging to t hat section of 

 the genus in which the pronotal disk is more decidedly constricted and the 

 tegmina narrower. 



u To this species, E. puncticosta Bolivar (Asoc. Espanola Prog. Cienc, Sec. 4a, 

 Cien. Nat., Junio, p. 8, (1913)) is apparently also related, differing, however, 

 in a number of important features. It is unfortunate that that author chose 

 to describe as new an imperfect female of this genus which contains so very many 

 species and more unfortunate that such important measurements as the pronotal 

 width, proportions of its lateral lobes and tegminal width were not given.
