TERRESTRIAT. FAMILIES OF UEMIPTERA-I I ETKUOPTERA 135 



Head elongate (I'late X, fig. 3), just under one and a half times as long (0.53 mm.) 

 as width, with eyes (0.36 mm.), anterior margin of eye inserted very slightly behind middle 

 of lateral margin, head somewhat constricted in front of insertion of antennae and also before 

 the posterior margin; rostrum reaching to posterior margin of anterior coxae; first antennal 

 joint reaching just to apex of head, second three and a third times the length of the first, 

 third twice the length of the first and very slightly shorter than fourth (0.11, 0.40, 0.24, 

 0.27 mm.), second joint slightly thickened baso-apically, third and fourth hardly narrower 

 than the middle of the third. 



Pronolum twice as wide posteriorly (0.73 mm.) as long (0.36 mm.) with a very distinct 

 apical collar less than half the posterior width (0.31 mm.) and marked transverse impression, 

 disc finely rugose and covered with very fine short pale hairs, lateral margins sinuate, some- 

 what raised and marginate, posterior angles sub-acute, directed backward and not projecting 

 laterally. 



Scutellum slightly shorter than pronotum, and one and a half times as wide (0.44 mm.) 

 as long (0.29 mm.), disc with sparse, very short fine pale hairs, little raised anteriorly, 

 remotely punctate and nitid, slightly depressed before apex which is rugulose. 



Presternum rugose, its disc flattened centrally, posterior margin produced to form an 

 acute xyphus between the anterior coxae. 



Mesosternum nitid, very finely and regularly rugulose, posterior margin narrowly emargi- 

 nate, disc with a fine groove running forward from the emargination and becoming obsolete 

 anteriorly. 



Metasternum transverse, between the widely separated posterior coxae, but little raiseil, 

 coarsely and irregularly rugose, posterior margin truncate. 



Orifice of metathoracic scent-gland straight, produced rather prominently at the outer 

 end (Plate X, fig. 7). 



Tibiae of all legs but little longer than femora (ant. 0.51, 0.55; inter. 0.51, 0.55; post. 

 0.80,0.87 mm.). 



Elytra and wings macropterous, the latter without a hamus (Plate X, fig. 6). 



Abdomen distinctly surpassed by the elytra. 



S Left paramere short, broad and semicircular (Plate X, fig. 8), right paramere vestigial. 

 Length 2.55 mm., breadth 0.80 mm, 



Indian Tibet. 3 5 5 (holofype and paratypes) Igu, in the Indus \'alley above Leh, on 

 the bark of Populus sp. ; altitude 3417 m. (11,210 ft.), Sept., 1932. 



The present species is anomalous in that it lacks the hamus of the wing cell, a character 

 which would remove it from the Anthocoraria and place it in the Lyctocoraria as defined by 

 Poppius (1909). Eetemnus paradoxus, however, runs down perfectly to its genus in the key 

 to the Anthocoraria given by this author, if once its membership in that tribe be admitted. 

 Apart from the absence of the hamus it appears tn lie an entirely normal member of its genus. 

 If, therefore, it is to be removed from the Anthocoraria, a new genus of the Lyctocoraria 

 must be defined, isolated from all the other memlwrs of that tribe, and differing only from 

 the Anthocorarian genus Eetemnus in the single character under discussion. This is clearly an 

 unsatisfactory proceeding and the present species is therefore described as an Eetemnus. It 

 is clear that the value of the presence and position of a hamus as a major taxonomic character 

 is dubious, but I am not in a position to revise the tribal characters of the Anthocoridae,
