1922] NATURAL SCIENCES OF PHILADELPHIA 257 



General coloration pale yellowish brown, probably light green 

 in life. The genicular lobes of the cephalic and caudal femora are 

 tipped with a suffusion of dark brown, these markings not as 

 decided or as conspicuous as in dicera. The intersections of the 

 antennal segments are strongly embrowned, at intervals being 

 stronger and forming distinct annuli. Tegmina with sutural 

 margins faintly embrowned and with areolae toward this margin 

 forming a number of vague brown spots. 



Length of body (females) 12.2, 90 11.4 and 13; length of pronotum 

 4, 3.9 and 4.2; total width of pronotum 2.2, 2.2 and 2.3; length of 

 pronotal lateral lobe 2.7, 2.6 and 2.7; depth of pronotal lateral 

 lobe 2, 1.9 and 2; length of tegmen 20, 18.5 and 19.3; width of 

 tegmen 2.3, 2.2 and 2.3; length of cephalic femur 5.7, 5.6 and 5.8; 

 length of caudal femur 13.2, 12.8 and 12.8; length of ovipositor 

 8.7, 8 and 8.5 mm. 



Two paratypic females, bearing the same data as the type, are 

 before us. 



Xiphidiopsis drepanophora new species. Plate XIX, figure 14; plate XX, figures 1, 2, 

 3 and 4. 



This is the first species of the present genus known to us which, 

 in the male sex, has the ultimate tergite produced latero-ventrad 

 into a specialized projection between the cerci, thus forming a sort 

 of yoke. 



The genitalia for both sexes are highly distinctive. 



Type: d* ; Kolambugan, Mindanao, Philippine Islands. (From 

 C. F. Baker.) [Hebard Collection, Type no. 825.] 



Size large for the genus, form slender but comparatively broad 

 for the genus. Vertex weakly but distinctly sulcate. Last joint 

 of maxillary palpus equal in length to fourth. Pronotum elongate, 

 the metazona produced caudad and slightly exceeding the prozona 

 in length, its surface slightly more convex than in X. dicera here 

 described. Pronotal lateral lobes as in X. cryptosticta here de- 

 scribed, except that the concavity of the caudal margin is very 

 slightly stronger than that opposite the thoracic foramen. Teg- 

 mina and wings fully developed. Ultimate tergite triangularly 

 produced with apex bi-mammate, the apices of these each forming 

 a blunt and decurved denticulation. Supra-anal plate concealed. 

 Cercus moderately stout, extending to apex of subgenital plate, 

 there suddenly doubled-in upon itself to near base, thence with 

 distal portion curving broadly inward, scythe-like., with acute apex 

 projecting on opposite side of body. Above the subgenital plate 

 and between it and the scythe-like portions of the cerci the large 

 yoke of the ultimate tergite projects upward and extends beyond 

 the apex of the ultimate tergite; this process is medio-longitudinally 

 carinate ventrad opposite the distal emargination of the subgenital

The measurements of the type are given first.
