CLEPTES. 417 



Abdomen (fig. 148) pseudosessile, more or less transverse at 

 base, either convex above and below (Cleptince), or convex above 

 and concave below (remaining subfamilies), oval, roundly sub- 

 quadrate, elongate, with the sides parallel, or broad at base with 

 the sides (sometimes only sides of the apical segment) convergent 

 posteriorly. In only two subfamilies the abdomen has more than 

 three visible segments, the remaining segments being highly 

 contractile, tubular, and generally only in the $ partially exserted. 



The Chrysididse may for our limited fauna be conveniently 

 divided into four subfamilies characterized as follows :

Subfamily CLEFIIN^E. 



The Cleptince comprise two genera, Cleptes, Latr., and Httero- 

 ccelia, Dahlb. No representative of either has, so far as I am 

 aware, been recorded from within our limits, but species of Cltptes 

 very probably, and of Heteroccelia possibly, may be discovered in 

 the mingling of Pakearctic with Indo-Malayan forms occurring in 

 Northern India and at high elevations further -south and east : I 

 give, therefore, diagnoses of both genera.
