diagnosis, seem to show tliat the species may be correctly determined. 

 Referring, however, to Fieber's original descriptions and figures in 

 the Ent. Monogr., it will be seen that, except in its more elongate 

 form, O. plaUjcliila differs but little from O. cerviua, and botli may 

 really be but one species. At any rate, Fieber has disposed of the ^J 

 as belonging to O. cerviua, Germ, (ut supra), and has therefore 

 weakened the claim of hmplafi/cJiila to be acknowledged as a good 

 species. 



Monanthia (0.) intermedia, Flor, is referred by Fieber to O. 

 nigrina, Fall., thus, " ilf. intermedia, Flor, ist die wahi'e O. cinerea, 

 " Fieb. Beide sind aber gleich mit O. {Tingis) nigrina, Yvll., nach 

 " den Bchwedische Original-Exemplarcn, obgleich Fallen in der Besch- 

 "reibungdie Farbe der Fiihler nicht angibt " (Wien. ent. Monats., 

 vii, 56). 



"3. O. NIGEINA. 



Tingis nigrina, Fall." 



This species is, apparently, understood in the same sense as by 

 Fieber, his description being quoted, but the diagnosis makes no 

 reference to the rounded anterior angles of the sides of the jn'onotum, 

 or to the anterior shortening of the side keels. Tingis pusilla. Fall., 

 and O. cinerea, Flor., are both quoted as the apterous form of O. 

 nigrina ; but Fieber, probably on insufficient grounds, has retained 

 O. pusilla, Fall., as a distinct species = 0. macrophtlialma, Fieb., O. 

 cinerea, Flor (AVien. ent. Monats., vii, 57). I have recently seen a 

 British example ; and, when describing it hereafter, I shall revert to 

 the subject of the synonymy. 



"4. O. CTLINDEICOENIS, n. sp." 



Of this it is said, inter alia " pracedenti similis et affinis, sed fere 

 " duplo minor, antennis articulo 3° nigro, crassitie spquali, prothoracis 

 " angulis anticis et lobo medio adhuc minus productis." 



"5. O. PAEVULA. 



Tingis parvula, Fall. 

 Orthostira parvula, Flor. 

 „ ohscura, Fieb." 



This is probably correct. Fieber says O. parvula. Fall., was un- 

 known to him (Eur. Hem., 384) ; but the species is O. ohscara, II. -S., 

 and is so cited by Fieber.
