1924 ] Systematic Position of the Family Termitaphididce 267 
which form a practically continuous lamina encircling the whole. 
Termitaphididce (n. n.) 
As regards the position of the series Phloeobiotica, the dis~ 
CO very of arolia or similar structures in the Aradid, Ctenoneurusi 
is a further indication that Bergroth is correct in considering it 
nearest related to the Pentatomoids. Reuter was impressed by 
the fact that the eggs of Pentatomoids and of Coreoids are 
operculate, the embryo being furnished with a peculiar egg- 
burster for forcing up this lid; while the ova of Aradids, accord- 
ing to Heidemann, lack lids entirely and resemble more those of 
Lygseids. The operculum and correlated egg-burster are, how- 
ever, by no means universal in the Pentatomoids, since they are 
totally lacking in the New Zealand Acanthosomatine genera, 
Oncacontias Breddin and Rhopalimorpha Mayr. The writer’s 
notes on these insects are now in the press. In addition, obser- 
vations now being carried out on certain North American 
Coreoids indicate a lack of these structures in this superfamily 
also. Since the above was written I have seen Barber’s (Psyche, 
1923) description of the egg of aradus ^.-lineatus, which has a 
distinct cap and chorial processes. 
Biology of Termitaphidtdae. 
Very little is known under this heading. All the recorded 
specimens have been collected in association with termites, of 
which the following species have been identified. The hosts of 
Dr. Wheeler’s Panama examples were kindly determined by 
Mr. Banks, those of the other Panama material by Dr. Snyder. —
