examination. Silvestri, however, in all his work characterizes it 
as four-segmented and shows four very distinct segments in his 
figures. Such distinctness is certainly in error. The second 
segment, reckoning on this basis, is very indistinctly articulated 
and the present writer is by no means sure that it constitutes a 
true segment. (Figs. 2, 3). 
The dorsal pores described and figured by Morrison are 
unlike anything known in other Heteroptera. Possibly, how- 
ever, this worker’s technique would reveal similar structures in 
other families. 
To sum up it would appear that the Termitaphididae may be 
regarded as Aradoids specialized, in some respects degeneratively 
(absence of wings, eyes, ocelli and rostral sulcus), in others ad- 
ditionally (lateral lamination and armature and folded antennae 
in Termitaradus; physogastry in T ermitayhis) , for a life of ter- 
mitophily. 
The diagnosis of the series Phloeobiotica (=superfamily 
Aradoidea) as set out by Reuter in 1912 and quoted above, may 
be modified as follows to include the Termitaphididae. — 
Arolia present or absent; head horizontal, much prolonged 
between the antennae or else furnished with an acute antenni- 
ferous tubercle; a rostral sulcus formed by the bucculae present 
or absent; ocelli absent; rostrum 4-segmented, often thickened. 
Hemielytra when present formed of clavus, corium and mem- 
brane; clavus narrowed towards the apex and never reaching 
beyond apex of scutellum. Membrane with some irregular and 
anastomosing veins or rarely completely destitute of venation. 
Meso-and meta-pleura always simple. Posterior coxae rotatory. 
Tarsi 2-segmented. Body except in Termitaphis flattened above 
and below. 
This series and superfamily comprises two families dis- 
tinguished as follows. — 
Tylus forming anterior projection of head; bucculae forming 
a rostral sulcus; margin of body more or less simple or furnished 
with well separated irregular lobes Aradidce (Spin.) 
Tylus at end of a deep incision extending caudally from 
anterior margin of head; bucculae forming no appreciable rostral 
sulcus; margin of bodj^ furnished with lobes, separate or fused,
