142 FAMILY EVANIID^. 



EVANIELLA Bradley. 



Evmiia Auctores, ad partem. 

 1905. Evdniella Bradley, Can. Ent., February, xxxvii. p. 63. 



Type. — Evania unicolor Ash. [nee '^•Ay']=^Evaniella semceodu n. s;p. 



The labium (Fig. 35) is narrowly oval, not concealing the ligula ; 

 the third joint of the labial palpi is ovoid, not triangular, longer 

 than broad ; the eyes are in E. californica (Fig. 9) extremely 

 small, so that they do not reach much below the base of the an- 

 tennse, normally they are longer (Fig. 16) ; the antenme are fili- 

 form, situated on a convexity of the forehead, or if in a slight con- 

 cavity there is at least no distinct rim below. 



The metapleurse have at most a polished spot on the upper corner, 

 often none at all ; the sides of the propodeum are not peculiarly 

 sculptured ; the furcula is usually with more or less divergent short 

 tynes, often obscured by vestiture. 



The posterior legs are long, and without spines. 



The wings in all species known to me are hyaline; and the veins 

 R4_ M beyond m-cu, Mi-^s, Mi, M2 and m are wanting, or present 

 only as a trace (Fig. 83). 



The shape of the abdomen is more or less intermediate between 

 Evaniini and Hyptiini. The abdomen of the female is quite or 

 nearly round, never distinctly triangular, but in one specimen is 

 nearly so; there is sometimes a slight production of the pygidium 

 into a point containing the ovipositor. The abdomen of the male 

 varies from round to narrowly oval {E. neomexicana). 



So far there are only five species of the genus known, three from 

 North America, one from Cuba and one from British Guiana. But 

 it is probable that maqy, at least of the South and Central Ameri- 

 can, Evanise really belong here.
