of the body and showing the structure described in the key 
below. Some of the Panama material showed an upward curling 
of the laminae in alcohol, but the condition thus artificially 
produced was not even superficially similar to that in Termi- 
taphis. The Panauia species is strongly flattened above and 
below, both in alcohol specimens and in life (Professor Wheeler), 
whereas Termitaphis would be rotund even were the laminae 
removed entirely. A new genus is therefore erected for the 
Panama species and for all other species described since T. circum- 
vallata. The Panama material was used as the genotype as it is 
the best known to me. 
Silvestri’s family diagnosis (1911, p. 232) may be modified 
by deletion of the phrase ‘Tor pus valde depressum,” and by 
changing his statement regarding stigmata to read as follows: 
stigmata 9, of which two are thoracic, and seven abdominal. 
The two genera may be separated as follows: Termitaphis, 
Wasm. (1902, p. 105); Body egg-shaped, surrounded by a 
strongly incurved and upcurved, dorso-lateral segmentally di- 
vided lamina, the edges of which are further divided into 
distinct, often quite distantly separated lobules each with a 
long fine almost smooth flagellum. 
Type, T. circumvallata Wasm. 
Termitaradiis, gen nov., Entire body strongly flattened above 
and below and surrounded by a flat lateral segmentally divided 
lamina the margin of which is crenulate forming short non- 
separated lobules, each provided with a short, circular, clavate 
or lanceolate flabellum with serrate edges. 
Type, T. panamensis, sp. nov. 
In addition, the tylus, covering the setal coil, is in Ter- 
mitaphis strongly protuberant, while in the other genus it shares 
the general flattening of the body. In the structure of the ros- 
trum, antennae, legs and last ventral segments of the female the 
two genera are similar. 
To Wasmann’s original description of T. circumvallata may 
be added the following: marginal lamina on each side divided 
into 13 lobes (Wasmann did not count the minute 8th abdominal), 
bearing lobules as follows: 6, 3 (head), 9 (prothorax), 7 (meso- 
thorax), 7-8 (metathorax), 8-10, 8-9, 9-10, 8-9, 7, 6, 5, 3 (the 8
