I mil Luiahle to determine the relation of this species to our other 

 American species from the above description, and have omitted it 

 from the key. 



THE EXOTIC EVANIIN^. 



TABLE TO THE GENERA OF EVANIIN^. 



1. Abdomen of tbe female distinctly triangular, tbe apex produced into a short 



process from which issues the ovipositor (Fig. IS) ; abdomen of the 

 male more or less narrowly oval ; antennse inserted in a single dis- 

 tinctly impressed basin, bordered usually at least on the lower side by 

 a carina; usuallyan interantennal carina ])resent ; metauotum as seen 

 from the side more or less deeply depressed, the sides of the depres- 

 sion abrupt (Fig. 62), (Tribe Evaniini) (2). 



Al)domen of the female nearly circular (rarely somewhat triangular), the apex 

 not produced into a process (or rarely slightly produced) ; abdomen of 

 the male the same shape as that of the female (sometimes oval in 

 Evaniella); antenna' not inserted in a distinct impressed basin, at least 

 without any carina below or beside them, rarely if ever between 

 them, the front usually distinctly convex; metauotum as seen from 

 the side less deeply de])ressed, the sides sloping gi-adually (Fig. 63), 

 (Tribe Hyptiini) (5). 



2. Front wings with the cell E -|- 1st Ri and M^^ not coalescent, M3+.t and r-m 



usually not interstitial, but strongly arcuate (Figs. 75-79) (3). 



[Cells R + 1st El and M4 coalescent; M:i-f4 and r-m interstitial, forming a 

 nearly straight line (Fig. 82) Evaiiisciis Szepligeti.*] 



3. Posterior tibiie and tarsi provided with very distinct stout spines, arranged 



rather regularly over their surface ... .(4). 



Posterior tibiie and tarsi without any spines (Fig. 60) ; labium modified into 

 a highly chitinized pear-shaped plate, which nearly covers and con- 

 ceals the ligula (Figs. 28 and 29) Fvaiiia Fabricius. 



■■•■ I have not seen tliis genus, but lieiieve that it belongs in the llyjitiini 

 rather than here.
