CHRYSIDIDjE 



The Chrysids, or Hymenoptera tubulifera, are insects with brilliant 

 (chiefly metallic) colours, i3-jointed antennas in both sexes, and single- 

 jointed trochanters, which last character they share with the Aculeata. 

 The neuration of their wings, though very ill-developed or rather per- 

 haps obsolescent, also connects them on the whole with that group. 

 The apical segments of their abdomens are thinly membranous, nearly 

 colourless, and so retracted one within another (telescope-fashion) into 

 the body of the insect, that as a rule only the three basal segments are 

 visible. The females are armed with a sting-like ovipositor, but, except 

 in Cleptes, no poison-bag occurs. That genus is believed to be in some 

 way parasitic on Tentbredinidte (according to Lepelletier on Nematus), 

 but scarcely anything is really known on the subject. Other Chrysids 

 infest the cells of various Aculeata, depositing eggs, from which larvae 

 are produced, which devour the aculeate larvae, and appear as imagines in 

 their stead. Ellampus seems to attack in this way chiefly bramble-pierc- 

 ing genera like Pempbredon ; Hedychrum and Hedychridium infest rather 

 the genera that burrow in sand (e.g. Cerceris, Tachysphex and Astatus) ; 

 Chrysis ignita attacks many solitary wasps and bees of various habits ; 

 C. viridula and neglecta are especially attached to Odynerus spinipes, while 

 C. cyanea is to be found almost exclusively about old palings and the like 

 which are riddled with the burrows of Chelostoma, T'rypoxylon, etc. 



We have but few species of Chrysids in England, perhaps not 

 more than five-and-twenty, and I have myself taken most of these in 

 Surrey. Chrysis birsuta, Gerst, and osmiee, Th., are probably confined to
