Cheiloneurus viridiscutum (Girault)
Synonymy.—Cristatithorax Girault = Cheiloneurus Westwood [Mercet, 1921].
Natural host.—Ellipsidion australe, Australia, Queensland (Dodd, 1917).
Comperia merceti (Compere)
Synonymy.—Comperia merceti var. falsicornis Gomes [Peck, 1951].
Natural hosts.—Blattella germanica, Brazil, Distrito Federal (Gomes, 1941): In the English summary of his paper, Gomes states that C. merceti var. falsicornis was reared from B. germanica. However, in the body of the paper, he states that the supposed origin of the parasite was the oötheca of B. germanica. Burks (personal communication, 1956) does not believe that this wasp parasitizes the eggs of B. germanica. We (unpublished data, 1957) exposed six oöthecae of B. germanica to C. merceti. In order to retard water loss the oöthecae were removed from the females by cutting the insects in two so that each oötheca remained attached to the posterior part of the abdomen. No wasps developed in these oöthecae.
Supella supellectilium, U.S.A., Kansas (Lawson, 1954a); Hawaii (Zimmerman, 1944; Compere, 1946; Keck, 1951).
Adult behavior.—Males and nonovipositing females showed a flea-like jumping tendency. Adults were attracted to light and were found near windows. Both sexes pursued an erratic course in walking and continually touched the surface with their antennae. (Lawson, 1954a.)
Oviposition.—The wasp (pl. [34], B) selected a site on an oötheca with the sheath of her ovipositor; it was uncertain whether there was a definite preference for oviposition sites. Wasp tended to choose a nearly horizontal position for oviposition. She preferred to oviposit into eggs about 2 weeks old, although she would place eggs in oöthecae less than a week old and in embryos in the green band stage. There were 1-50 oviposition punctures per oötheca. (Lawson, 1954a.)
