TKRRF.STRIAI, FAMILIES OF HEM I I'TF.K A- H F.TKKOl'TF.R A IJl 



y\ntennae with first and second jdints sub.-tiual, half as loiiy again as third, tourtli twice 

 as long as the latter, fifth just over half as long again as fourth (0.27, 0.27, 0.18, 0.36, 

 0.58 mm.). 



Rostrum reaching to posterior coxae. 



Pronotum just over twice as wide as long (3.35, 1.53 mm.), with anterior margin evenly 

 concave when seen from in front and practically straight when viewed from above, posterior 

 margin almost straight centrally, laterally bent forward to the rounded posterior angles, lat- 

 eral margins emarginate behind the subrectangular anterior angles, disc with a central 

 impunctate carina, which in its posterior third is fragmented to form two irregular tubercles, 

 and with a transverse depression, obsolete centrally, in front of which are two raised areas 

 divided by transverse V-shaped depressions (probably apodenie bases) and falling off abruptly 

 toward the lateral margins. 



Scutellum with a longitudinal central carina, reaching to just beyond its centre. (The 

 specimen also shows two folds running obliquely from the anterior angles to behind the middle 

 of the disc, but these appear to be due to an injury that has also removed the right elytron 

 and so buckled the scutellum on that side as to make measurement impossible. ) 



Marginal abdominal tubercles but moderately prominent (Plate VIII, fig. 4). 



Length 4.8 m. ; breadth ?>.?>S m. 



Indian Tibet: 1 $ (type) I'eldo-le, near N. end of Tso Moriri, altitude 4529 m. (14,855 

 ft.), among roots of short grass. 



This species, as is indicated by its subparallel head, subrectangular anterior pronotal 

 angles and the coloration of its antennae, clearly belongs in the fourth cohort of the key in 

 Reuter's monograjjh of the genus (1908). It differs from the species placed in that group in 

 its small size, unarmed trochanters, less conspicuous marginal tubercles, and apparently in the 

 somewhat elevated center of the vertex behind the clypeus. 



P. rcnlcri Kiritshenko (1910), the only species described since Reuter's monograph. 

 belongs to first cohort. The present species appears to be the smallest member of the genus. 



Family COREIDAE 



Subfamily Corizinae 



2. Stictoplciira sp. 



Indian Tibet : 1 9 antl 1 nymph, between Tsak-shang and Tsak-ra, road from Tso 

 Moriri to Tso Kar, altitude 4570 m. ( c. 15,000 ft.), 1 Sept., 1932. 



The single adult before me is a female in not very good condition. It is most closely 

 allied to n\sioidcs Kiritshenko, but since the genus contains several very similar species and 

 since these probably cannot be satisfactorily determined without a study of the S genitalia the 

 present specimen is l)est left unnamed.
