hairs placed there, which form a very slender cylinder corresponding to 
the base of the developed hairs. These filaments cease in the centre of 
the developed hairs, but traverse the rudimentary ones, appearing beyond 
them as a very delicate rounded point. The former are probably organs 
of touch, the latter of taste.

The writer criticizes the observations of Graber, in Arch. mikr. Anat. 
xvi. (1878), on Diptera, and of Berte on Pulex. The structure of the 
basal joint of the antennae appears to be very similar in all Diptera.

Entirely rewritten, the first edition having been published in 1858. 
A general introduction and bibliography is prefixed, and a great number 
of observations are appended, among which it is only possible here to 
notice new genera and species. The following Lew names are proposed 
for preoccupied genera : — Neoempheria (EmpJieria, Winn.), p. 9, Neo~ 
glaphyroptera {GlapTi., Winn.), p. 10, Idioplasta {Protoplasa and -plasta, 
O.-S.), p. 36, Neoexaireta (Ex. Schin.), p. 44, Neorondania (Rond., Jaen.), 
p. 50, Neoeristicus (Er., Loew), p. 81, Neomochtherus (Mochth., Loew), 
Neoitamus {Itam., Loew), p. 82, Neoidiotypa (Idiot., Loew), p. 187, Ne- 
aspilota (Aspil., Loew), p. 192.

The Diptera are divided into Hippoboscita, Muscita, and Pulicita, and 
the first is subdivided into the families Braulidce (new characters of the 
genus Braula added), Nycteribiidce, Hippoboscidce, and Streblidce.

Several species have rudimentary wings, and their hair and bristles are 
proportionately undeveloped likewise. The following species described by 
Eaton in Ent. M. M. xii., are redescribed and figured: — Calycopteryx 
moseleyi, p. 239, Amalopteryx maritima, p. 241, Apetenus litoralis, Anata- 
lanta aptera, Limnophyes pusillus, and Halirytus amphibius.
