13. Tibetocoris margaretae sp. n. 



Head, pronotum, scutelliim and elytra clothed above with long irregular sparse pale 

 pubescence, which is somewhat tonientose on the head ; and with a few black hairs on the 

 elytra. I'ale greyish white, tinged with yellowish green, vertex near eyes minutely trans- 

 versely striate with brown, pronotum. scutellum, elytra, and distal third of femora with 

 minute brown spots, antennae greyish brown, liasal joint paler, tarsi brown becoming almost 

 black apically, inesosternum and apical joint of rostrum black, alxlomen greenish grey. First 

 joint of antenna with two subapical black bristles, second joint narrow proximally, somewhat 

 widened apically but throughout narrower than the first, third and fourth subequal in 

 width, and slightly narrower than the proximal end of the second; second joint just under 

 three times as long as the first ; third joint about three-fifths as long as the second and fourth 

 three-fifths the third (0.33, 0.95, 0.58, 0.33 mm.). 



Anterior femur with three conspicuous subapical and three small apical bristles, tibia 

 with about nine black liristles; the tibia one and one-third times as long as the femur and 

 twice the length of the tarsus (0.80, 0.98, 0..^1 mm.), the tarsal joints overlapping at their 

 articulations, the second a little longer than the first and a little slmrler than the third which is 

 twice as long as the claws (0.15, 0.18, 0.22, 0.11 mm.). 



Intermediate femur with two apical and one conspicuous subapical bristle tibia with 

 about 16 bristles, tibia just over one and one-third times the length of the femur and two 

 and a half times the tarsus (0.90, 1.24, 0.51 mm.), second tarsal joint twice as long as first, 

 third just longer than .second and more than twice as long as claws (0.12, 0.24, 0.25, 0.11 

 mm. I. Posterior femur with two conspicuous subapical bristles, tibia with about 16 bristles, 

 tibia about one and a half times as long as femur and three times as long as the tarsus 

 (1.34, 2.04, 0.69 mm.), second tarsal joint two and a half times as long as the first and 

 slightly longer than the third which is just over twice as long as the claws (0.15,0.36,0.33, 

 0.15 mm.).

The present genus is probably most clossly allied to Tuptonia Renter, from which it 

 differs mainly in the longer pseudarolia. This character, if the feeble markings on the 

 femora be neglected, would bring the genus into the neighbourhood of Asciodema in Renter's 

 key (1884); Asciodema, however, differs m:irkedly from V'/fcc/orwrn in the structure of the 

 head and legs. The specimens are all somewhat teneral and the prosternuin therefore tends 

 to be distorted, but in the l:)est preserved of them it shows no trace whatever of being convex, 

 in this rather resembling the series of genera originally separated by Renter as the flivision 

 Oncot\Iaria.
