apices broadly subtruncate and reacliino- tlffe penultimate

Genus Platylomia. 



Platyhmin, Stal (nom., nee descrip.), CEfv. Vet.-Ak. Fcirh. 1870, 

 p. 708, note. 



Head (including eyes) about as wide or a little wider than 

 base of mesonotum, about or almost as long as breadth 

 between eyes ; pronotum centrally about or almost as long as 

 mesonotum (excluding basal cruciform elevation), its lateral 

 margins always distinctly, sometimes strongly, and generally 

 acutely toothed ; abdomen considerably longer than space 

 between apex of head and base of cruciform elevation ; tym- 

 pana completely covered ; rostrum reaching or passing the 

 posterior coxai ; opercula more or less elongate, concavely 

 sinuate on each side of basal area, their apices rounded or 

 subacute, occupying lateral abdominal areas, always well 

 separated and seldom reaching disk ; tegmina and wino-s 

 hyaline, the venation sometimes fuscously spotted. 



Type, P. spinosa, Fabr. (Tettirjonia) . 



I use Stal\s name for this genus, as the type he proposed 

 {Cic. jiavida^ Guer.) is included in it. His description, 

 however, cannot be accepted, as, evidently referring to 

 Guerin^s figure only, he states, " ramo vente ulnaris interioris 

 recto vel leviter curvato," a charactei- given by the artist and 

 not found in the species. 



Plati/Ioini'a assamenfis, sp. n. 



Allied to P. umhrata, Dist. (Mon. Orient. Cicad. tab. v. 

 figs. 11 a, b), and ditiering principally by the size and shape 

 of the opercula, whicii just pass the posterior margin of ttie 

 penultimate abdominal segment, with their apices suddenly 

 obtusely angulate ; the tegmina are shorter, and thus appa- 

 rently broader, and are without the marginal spots at the 

 apices of the longitudinal veins to tlie apical areas and 

 the inf uscated transverse veins at the bases of tif th and seventh 

 apical areas ; the markings of the mesonotum are similar to 

 those of P. umbrata, but there is also a distinct black elongate 

 spot on each lateral area. 



Long., excl. tegm., ^ -40 mm. ; exp. tegm. Ill mm.
