TERRESTRIAL FAMILIES OF HEMIPTERA-HETEROPTEKA 129 



of the pronotum, basal jtjiiit sub-cylindrical, just over twice as long as wide (0.15 mm.), 

 second joint just over twice as long as the first, third joint just over two-thirds as long as 

 the second, fourth suljequal to the latter (0.33, 0.76, 0.55, 0.74 mm. ) ; basal three joints 

 richly setose, the setae being slightly shorter than the maximum diameter of the first joint, 

 apical joint with a few setae basally and with fine short hairs throughout; rostrum long, 

 reaching almost to the center of the posterior coxae, second joint very slightly longer than 

 the first, third subequal to second, fourth subecjual to first. 



Pronotum trapeziform (Plate X, fig. 1 ), not greatly narrowed anteriorly, rather under 

 twice as wide as long (2.15, 1.16 mm.), sides moderately explanate, anterior margin slightly, 

 evenly and roundly excavate, lateral margins neither reflexed or marginated, slightly con- 

 verging anteriorly from just before the posterior angles, slightly emarginate behind middle, 

 with about eight setae on their anterior portion, including the anterior angles. 



Scutelluni equal in length to the pronotum and basally slightly wider than its length 

 (1.34, 1.16 mm.). Mesosternum with well-developed and closely appro.ximated tubercles, 

 disc of metasternum not very conspicuously impressed. 



Elytra nearly reaching the apex of the abdomen. 



Posterior tibia a little shorter than the posterior width of the pronotum, and just over 

 twice as long as the basal tarsal joint, the latter two and a half times as long as the subequal 

 second and third joints together, claws two-fifths as long as one of the latter (2.00, 0.91, 

 0.18, 0.1 S, 0.07 mm.). 



Length 5 {type) 5.45, breadth 2.43 mm. 



Indian Tibet. 2 9? {^yps and paratype). L 77a. Renka-le, altitude 5136 m. 

 (16,917 ft.), between Mitpal Tso and Yaye Tso, on grassy bank in valley. 18 Aug., 1932. 



In the paratype the anterif)r margin of the pronotum is practically straight centrally and 

 the elytra reach to the apex of the abdomen, the two specimens otherwise agree and are 

 undoubtedly conspecific. 



E. Iion'athiana is perhaps more closely allied to E. vcrbasci, than tt> any other species of 

 the genus known to me. It differs conspicuously in having much more setose antennae, the 

 fourth joints of which are subeejual to the second, rather less explanate lateral pronotal mar- 

 gins, in being narrower and in its dark greyish coloration. At first I believed my material 

 was to be referred to brezicornis Horv., but, on seeing a drawing of one of the present 

 specimens, Dr. Horvath pointed out to me that in my species the form of the pronotum 

 and antennae are very different. In brevicornis the lateral margins of the former are quite 

 straight and converge more markedly anteriorly, while the fourth joint of the antenna is 

 very much shorter than in the present species. I am greatly indebted to Dr. Horvath for 

 calling my attention to these points and have much pleasure in associating this high-altitude 

 species with his name. 



Dolmacoris^ gen. n. 



Head bearing conspicuous bristles, ocelli set well on vertex, close to the inner margins 

 of the eyes; antennae with first three joints and the extreme base of the fourth with well- 



' Tibetan sGrot-via. pronounced Dolnia, the most popular goddess of the lamaistic pantheon, better known by 

 the Sanskrit name of Tara. The specific name is in honor of my friend Dr. Helhnut de Terra, leader of the Yale 

 Nortli India E.xpeditiun.
