upon the back, but keeps them in a slanting position, so that it 
resembles an exceedingly small aphid or psocid. 
TERMITOXENIA WASMANN. 
Thorax with one pair of dorsal appendages, apparently the halteres. 
Halteres styliform or hooked at tip. Abdomen much swollen, curved 
downwards, anus directed forward. 
This most remarkable genus is represented by four termi- 
tophilous species from Africa and India (Wasmann, '00a). Only 
females are known, although Wasmann considers some of his 
specimens as hermaphrodites, as they apparently possessed 
both ovaries and testes. He says, in speaking of T. mirabilis: 
* Jetzt sehe ich an Schnittserien der letzteren, dass dieselben 
Hermaphroditen sind mit noch kleinen ovarien und gut ent- 
wickelten Hoden." On such evidence we must not, however, 
suppose that winged males do not occur. Other cases of her- 
maphroditism among insects have been noted, but in no case is 
it established to be anything more than a pathological condition 
of certain individuals. 
STETHOPATHUS WANDOLLECK. 
Both wings and halteres absent, ocelli present, epistoma not large and 
prominent. Thorax rounded. Abdomen elliptical, first four dorsal seg- 
ments strongly chitinized and well developed, covering the greater part of 
the dorsum of the abdomen. Abdomen not greatly retractile at apex 
ovipositor short. i 
Only one species of this genus has been described, S. ocellatus 
Wand. from the East Indies. The specimens were found upon 
carrion and in the flowers of the giant Arum (Amorphophallus). 
It was previously described by Dahl as the female of his 
Puliciphora lucifera, but because of his poor description and 
misunderstanding of its systematic position, Wandolleck 
redescribed it under a new name which it is probably best 
to adopt.
