E. BERGROTH, HEMIPTERA FROM BRITISH EAST AFRICA. 23 



e medio ad apicem angustata, per totam longitudinem venis 

 transversis instructa, his in dimidio basali areae abbreviatis. 

 solum partem externam areae occupantibus, in dimidio apicali 

 areae completis sed irregularibus, vena subradiali sat longe 

 a basi venae radialis exeunte, post medium tegminis in reticulum 

 anteapicale transemite, areis omnibus tegminum, cubitali 

 excepta, venulis transversis praeditis, his in parte subapicali 

 exteriore magis numer osis, linea transversa subai^icali multi- 

 flexuosula, cellulis apicalibus subalternatim petiolatis et ses- 

 silibus, cellulis subapicalibus quam ajjicalibus sessilibus bre- 

 vioribus, venis duabus clavi in medio conjimctis, area ejus 

 exteriore venis transversis complnribus in- 

 structa. Tibiae posticae spinis duabus ar- 

 matae. 



This genus is allied to Osaka Dist.,^ 

 but differs from it by shorter clypeus, much 

 longer mesonotum, different shape of the 

 costal membrane and costal area,^ the pre- 

 sence of träns verse veins in the costal area, 

 the more numerous and more irregularly 

 placed transverse veins of most of the other 

 areas, the absence of the transverse vein 

 in the cubital area, the much shorter sub- 

 apical tegminal cells, and the different claval Fig. 3. Syndetica in- 

 venation. Distant does not mention Avhe- teraerta. 



ther the lateral keels of the mesonotum in Osaka are simple 

 or forked, nor is this character clear from his figure. The 

 genera Osaka and Syndetica are by their transverse front 

 combined with laterally keeled clj^^eus exactly intermediate 

 between Melichar's divisions Eicaniaria and Bladinaria {Nogo- 

 dinaria). If these divisions be maintained as distinct from 

 one another the Bladinaria can be characterized only by ha- 

 ving a laterally carinate clypeus, and the genera Salona Stål 

 and Semestra Jac. must be transferred to the Eicaniaria. Se- 



^ ScHMiDT has United Osaka relata Dist. with O. hyalina Dist., but 

 as Distant statos that the face in relata is »apical]y more oblique towards 

 clypeus», these species cannot be united without an examination of the 

 types. 



- In his descriptions of Ricaniinae Distant correctly calls the outer- 

 most tegminal area costal membrane, but the costal area is wrongly 

 termed by him »radial area»; this is very misleading, the radial area 

 (Melichar's subcostal area) lying, of course, between the radial and sub- 

 radial veins.
