140 TF.RKKSTKIAI. FAMIl-IF.S OF 1 1 KM 1 1'TI-.KA-TI ICTI-.Km^TFUA 



lirownisK yellow, fourtli joint black. Legs very pale greyish yellow, bases of coxae blackish, 

 femora with small brown spots, tibiae immaculate, third tarsal joints black; tibiae with 

 numerous fine black spines which do not arise from spots. Elytra hyaline t;rey throughout, 

 apices of corial nerves suffused with l)lack, covered throughout, but most strongly in the 

 lateral (anterior) region with fine black hairs. 



Head transverse, rather more than one and a halt limes as wide as lung (0.()0 mm., 

 0.37 mm.), evenly rounded and hardly produced anteriorly over the clypeus, the latter in 

 lateral view with its anterior margin straight ventrally; l)ucculae shorter than gula. 



Antennae moderately thick, the first joint suqiassing the apex of the head by al)OUt 

 three-quarters of its length, and about two-thirds the length of the vertex seen from above, 

 second joint two and two-thirds times as long as first, third just under three-fourths as long 

 as the second and fourth about three-fifths as long as third (0.25, 0.65, 0.45, 0.27 mm.). 



Rostrum apparently reaching just beyond middle of intermediate coxae (somewhat 

 damaged in tmique type), basal joint distinctly shorter than head. 



Pronotuiii anteriorly about four-fifths as wide as head with eyes, posteriorly about one 

 and four-fifths as wide as the head, just over twice the anterior breadth and just over twice 

 as wide as long (head width 0.60 mm., pronolum, anterior width 0.49 mm., posterior width 

 1.03 mm., length 0.4'* mm.), anterior collar well marked, its anterior margin very slightly 

 sinuate, calli well marked, subconfluent centrally, posterior transverse fossa lying just 

 anterior to center, sides rather sinuate, posterior margin widely emarginate, posterior part 

 of disc feebly rugose. 



Elytra about .six times as long as pronotum, and just over twice their greatest width, 

 outer margin very slightly explanate. Anterior coxae reaching to middle of mesosternum, 

 posterior tibiae (1.64 mm.) 2.73 times as long as width of head and eyes, third tarsal joints 

 suljequal to second. 



S Left paramere as in Plate X, fig. 13, with very long hairs on the basal part of the 

 shaft, and a small triangular projection, situated more apically tlian the corresponding pro- 

 jection in the preceding species and directed upwards. 



Length S (type) 3.69 mm., breadth 1.23 mm. 



Indian Tibet. 1 S (type) L 37, Ijetween Tangtse and Mugleb, altitude c. 4175 m., 

 among grasses, 27 June, 1932. 



This species is very close to the preceding, differing in the different coloration of the 

 head, the more sinuate lateral margins of the pronotum and in the left paramere. Both 

 species are allied to the above-mentioned Central Asiatic species and to anniilatns. From the 

 latter species D. scns_i^e differs in the coloration of the head and tibiae, from oriciilalis in the 

 coloration of the head and antennae, from montanus in the short basal joint of the latter.
