CERIOIDlNiE. 



Médium sized or moderately large, barc and elongate Aies 

 whieh are exceedingly like the Conopidœ and some of the smaller 

 wasps {Vesfidœ). They are characterised by the antenne which 

 arevery often placed on a long pétiole and which are elongate, 

 porrectèd and with a terminal style, and by the wings which 

 possess usually the costal border as far the vena spuria darkened, 

 and an Eristalis-\ikQ loop in Radius 4 + 5, from the bottom of 

 which a peculiar veinlet almost bisscts the cell beneath (R5) as in 

 the Microdontinœ ; Radio-median cross vein placed after Ihe 

 middle of cell M2. 



There is so far only about 70 species of this very distinct 

 and sha.rply defined group known. ïhey seem to be chiefly 

 représentée! in Central America and Africa but they also occur in 

 Europe. North America, Tasmania, India, Jamaica, Asia Minor 

 and Japan. 



Very little is known about the métamorphoses of this group. 

 Verrall states that C. cono'psoides bas been bred from fldwing sap, 

 but I strongly suspect them to posses some relation with Hymenop- 

 tera, especially ants.
