ART. 3 ORTHOPTEROID INSECTS FROM JAVA — CAUDELL 13 



very broadly rounded, the mesial portion of the ditk marked with 

 some irregular dark lines and spots, though not very conspicuously 

 so. Organs of flight considerably surpassing the tip of the abdomen; 

 tegmina with the discoid al sectors longitudinal, few in number; cos- 

 tal veins about a dozen in number, those at the mJddle of the tegmina 

 being half as long as the width of the tegmina; wings about twice as 

 long as broad, wholly membraneous and transparent with brown 

 venation; costal veins about nine in number, the apical two or three 

 forked, the basal seven strongly clavate apically, as is also the sub- 

 costal vein, which thus resembles one of the clavate costal veins, as 

 shown in Figure 2 ; ulnar vein four forked, all branches terminating 

 in the apical margin of the wing; a small apical triangle present. 



Legs yellowish, with the insertions of the rather slender concolorous 

 spines black; anterior femora with the anterior ventral margin armed 

 distally with two long spines, preceded by a row of exceedingly fine 

 and short spinules of 

 equal length, and 

 basad of these there 

 are four very long 

 stout spines. 



Abdomen above 

 with the segments 

 mesially fuscous, the 

 margins only yellow- 

 ish, and beneath the 

 color is yellowish with 



-, Fig. 2.— Wing of Margattea buitenzorgensi.'!, new species 



some rather small 



and obsciu-e blackish spots along the sides; supra-anal plate about 

 twice as broad as long, apically rounded, entire, the dorsal surface 

 with a slight longitudinal median carina; subgenital plate trans- 

 verse, apically rounded and entire; the lateral margins of this plate 

 in the single specimen studied are slightly rolled downward and 

 inward, making it probable that in life there are notches at the 

 intersections of the styles; styles yellow, very slender and terminating 

 in a hair; cerci long, distinctly segmented, somewhat flattened and 

 beneath shghtly infuscated toward the apex; dorsally the abdomen 

 has the second segment preceding the supra-anal plate apically and 

 mesially formed into a very small slightly raised recurved flap ter- 

 minated by a bunch of short yellow bristles; this modification is so 

 small as to be very easily overlooked.
