THE CANADIAN ENTO!\[OLOGIST. 



Apex of niargiiKil cull biictly truncate ; second and third cubital cells 

 each receiving a recurrent nervure at or a little beyond the middle; 

 cubitus in hind wings originating a little before the transverse 



median nervure Mesa, Saussure. 



(Type M. diapherogamia, Sauss.) 



Family XXXVL— Scoliids. 

 This family is very closely allied to the Myzitiidce, but may 

 be easily separated by having the eyes in the females distinctly 

 emarginate within. The males also have emarginate eyes, but are 

 more easily distinguishable by abdominal peculiarities, the tip ending 

 in three straight spines, but never in a single upward curved aculeus as in 

 the Myzinidce. 



The species are parasitic upon the larvns of beetles belonging to the 

 family Scarabaeid(E, and probably also upon other ground-inhabiting 

 beetle larv?e. 



Two subfamilies may be recognized : 

 Front wings with only one recurrent nervure ; if with two, the second 

 recurrent is incompletely formed, and bends backwards so as to unite 

 with the first, the second cubital cell receiving only one recurrent 



nervure Subfamily I. — Scoliinse. 



Front wings with two complete recurrent nervures, both of which are 



received by the second cubital cell Subfamily II. — Elidinse. 



Subfamily I. — Scoliince. 

 In this subfamily the front wings have only a single complete 

 recurrent nervure, which is received by the second cubital cell. The 

 group is evidently an offshoot from the Elidiiice, which have two 

 complete recurrent nervures.
