HEMIPTERA— HETEROPTERA. 



145 



bounded basally with a broad blackish-brown annulation ; intermediate and 

 posterior tibiae pale brown gradually becoming darker towards the extreme 

 bases which are white. 



Structure. — Head with anterior lobe slightly longer than posterior lobe 

 (25 : 23), the latter slightly shorter than width of head across eyes (23 : 24) ; 

 antennae very long and slender, first and second segments equal in length, 

 third very short, fourth rather more than three times as long as third ; relative 

 lengths of segments 280 : 280 : 15 : 50. Pronotum rather less than twice as 

 long as head (82 : 48), the basal lobe (fitting over apex of mesonotum) very short. 

 Visible part of mesonotum slightly shorter than head (45 : 48), rather obscurely 

 tri-sulcate ; metanotum rather shorter than mesonotum (40 : 45), obscurely 

 tricarinate. Relative lengths of anterior coxae, femora, tibiae and tarsi, 

 130 : 198 : 107 : 17 ; femur armed with six long spines, about ten shorter spines 

 and numerous small spines ; distance from base of femm- to first long spine 

 rather longer than from apex of femur to last long spine (60 : 50). Relative 

 lengths of intermediate femur and tibia, 362 : 507, and of posterior femur and 

 tibia 497 : 710. Abdomen more than one-half longer than head and thorax 

 together (365 : 215), slightly and gradually widened towards apex. 



Total length, 20 mm. 



Upolu :— Malololelei : 1 $ (type), 2,000 ft., 25.ii.1924. 



Closely allied to Gardena pacijica Kirk., but differing in the well-marked 

 white apices of the femora, and in the armature of the anterior femora, which 

 bear six instead of five long spines.

Miss Cheesman's species is apparently synonymous with the Hawaiian 

 Luteva insolida B. White, and, as her description was based on very poorly 

 preserved material from the Marquesas, while that of B. White is somewhat 

 inadequate, it has been thought advisable to redescribe the species from the 

 Samoan specimen.
