angles in a weakly decurved, socketed style, three times as long 

 as its basal width. Femoral genicular lobes bluntly rounded, tibial 

 spination normal. 



General coloration immaculate, buffy; probably a delicate, light 

 green in life. Eyes dark brown. Antennae weakly suffused with 

 brown at the intersection of each joint, a few of these widely spaced, 

 much heavier, giving a subannulate facies. 



Length of body 8.7, length of pronotum 3.8, greatest total width 

 of pronotum 2.3, length of pronotal lateral lobe 2.9, depth of pro- 

 notal lateral lobe 1.4, length of tegmen 9.2. width of tegmen 2.1, 

 length of cephalic femur 3.6, length of caudal femur 9.2 mm. 



The type is unique. 



Alloteratura bakeri new species. Plate XIX, figures 4 and 5. 



Though instantly recognizable by the distinctive male genitalia, 

 this sex of the present species agrees very closely in other respects 

 with a male of A. xiphidiopsis (Karny) before us. In the present 

 male the only other differences are seen to lie in the broader, 

 blunter vertex which is less distinctly sulcate, the less ample pro- 

 notum with proportionately slightly shorter lateral lobes and the 

 antennae which show no trace of annulation. 



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



Baker.) [Hebard Collection, Type no. 821.] 



The following characters are considered diagnostic for this 

 species, in addition to those noted in the generic description. Size 

 and form medium for the genus. Vertex broader and blunter than 

 in A. xiphidiopsis, flattened dorsad and showing a linear subsul- 

 cation. Pronotum very slightly less convex than in A . xiphidiopsis. 

 Lateral lobes of pronotum with ventro-cephalic and ventro-caudal 

 angles weakly indicated by broad convexities, the latter weakest 

 ventral angle rounded at ninety degrees, caudal margin with 

 humeral sinus deep, rounded obtuse-angulate. Tegmina and wings 

 fully developed. Ultimate tergite moderately produced, its distal 

 margin showing on each side two weak convexities, between which 

 it is dorsad broadly and weakly concave. Cerci very heavy, 

 swollen and irregular in contour, proximal three-fifths nearly as 

 broad as long, lamellate dorsad and swollen in ventral portion, 

 thence the cerci are cylindrical, produced dorsad, slanting inward, 

 scarcely tapering in proximal half, weakly tapering in distal half 

 to tin rounded and attingent apices. Mesad between the cerci 

 the yoke of the ultimate tergite projects caudad considerably 

 beyond the subgenital plate, its angulate apex is hooded with dorsal 

 surface medio-longitudinally sulcate, the ventral surface deplanate. 

 Subgenital plate with lateral margins broadly convex-convergent 

 to the narrowly truncate apex; the surface, on each side, just before 

 the apex, raisad and bearing a small, weakly decurved style, dis- 

 tinctly less than three times as long as its greatest width. Femoral 

 genicular lobes bluntly rounded, tibial spination normal.
