two small dark bands; pronotiim with darker mottlings. Tegmina hyaline, 

 clear, veins of similar color broken by dark marks, tubercles small 

 bearing dark macrotrichia ; wings hyaline with darker veins. 



Female. Macropterous ; length 4.8 mm., tegmen 4.2 nun. Anal 

 segment tubular, ventral surface grooved longitudinally, length twice 

 the width, anus at apex, ovipositor reaching to apex of anal segment. 

 Color similar to male. 



Described from eleven males and ten females from Tutuila, 

 Samoa, from sea level to 1200 feet elevation, and ten males 

 and three females from Savage Island or Niiie. (Kellers, April 

 to October, 1918.) Type No. 1013. The latter can be dis- 

 tinguished by the small projections at the angles of the 

 emargination being larger than in the Tutuila specimens. 



Ugyops bougainvillei sp. n. Fig. 9. 



Male. [Macropterous; length .5.7 mm., tegmen 5.4 mm. Length of 

 vertex 1.4 times the width at apex, which is slightly wider than base 

 and moderately rounded, base considerably before the middle of eyes; 

 length of face 2.4 times the width, narrowest between eyes, broadest 

 a little before apex, two median carinae distinct to apex; antennae 

 reaching beyond apex of clypeus, second joint twice the length of 

 the first. 



Anal segment large, length about 2.5 times the Avidth, tectiform, 

 anus near apex; pygofer long ventrally, short dorsally, medio-ventral 

 margin emarginate, produced in middle into two small processes, slightly 

 flattened laterally and pointed at apex, sides widely angularly produced; 

 genital styles subparallel sided, slightly curved and recurved, excavate 

 On front surface, the apex at outer angle produced into a small square 

 process turned at right angle to the body of style, the inner angle 

 produced into two processes, the distal one the larger; aedeagus long, 

 characteristic of the genus, the apical portion being longer than in 

 U. lieUersi. 



Stramineous, second ioint of antennae fuscous, the apical half 

 distinctly so, a faint trace of red between median frontal carinae, 

 fuscous along the hind margin of mesonotum. Tegmina hyaline, 

 stramineous, veins slightly darker, black or fuscous over greater portion 

 of subcosta, at base and before cross veins on radius and over tho 

 other veins to hind margin at these two points, fuscus at base of 

 margin of clavus, apex fuscous, forming a small spot at apex of radial 

 cell; tubercles small, bearing black macrotrichia; wings hyaline, veins 

 brown. 



Female. Macropterous; lengtli G.4 mm., tegmen 6 mm., (ivijxjsitor 

 projecting slightly beyond anal segment. Darker than the male, the 

 fuscous on veins of tegm'na darker and more extensive.
