of which the solenidions of tibiae II and III are coupled with protective hairs, but of which the solenidion of tibia IV is free, long, and tactile. The genus belongs to the group of rather small species that are never covered with foreign material, but of which the cerotegument is very thick, especially on the moniliform legs, whilst the adults often bear the larval and nymphal skins.

The species have three or four lateral apophyses: one (which is not always present) between leg I and leg II, two between II and III, and one between III and IV. We have been in doubt as to the nomenclature of these apophyses, for although they have generally been regarded as tectopedia, they do not protect the trochanteres. Grandjean (in litt.) recently proposed to us the following notation. The apophysis between I and II is restricted to some members of the
<taxonomicName id="E9F8CD97DF006FFCA12CD9AAD4865F33" family="Belbidae" pageId="0" pageNumber="141" rank="family">Belbidae</taxonomicName>
, and in the present paper it is simply called anterior apophysis (a.a.). The two apophyses between II and III occur in several families; they protect the sejugal stigma; here they are called anterior and posterior parastigmatic apophyses (a.p.a., a.p.p.). It is obvious that the fourth apophysis is a discidium (dis; cf. Grandjean, 1952, p. 31).

are no Spinae adnatae but there is often one pair of protuberances under the anterior border of the notogaster, opposite to a corresponding pair on the propodosoma; sometimes there is even a second pair of protuberances on the propodosoma, also situated in the posterior part.
