After an elaborate discussion of the structure and analogies of the 
thorax of ilf. vomitoria^ the writer arrives at the conclusion that it is 
almost exclusively mesothoracic, the pro- and meta- thorax and appen- 
dages being but slightly developed.

The proboscis consists of three principal portions, the base, mid- 
segment, and tip. The former contains (1) the fulcrum, sometimes 
improperly called the pharynx ; (2) two palpi, supported by a weak cross- 
piece of chitin ; and (3) a membranous sheath. The mid-segment folds 
on to the basal segment by an elbow-joint ; it includes the mentum, 
operculum, the plate curving upwards round the operculum, which forms 
a canal with it, and the lingua, or hypopharynx. The third segment, 
or tip, is a singular scraping and suctorial apparatus, with the oral open- 
ing on its upper part amidst the large prehensile lips, and when spread 
out, its surface is covered by a system of about eighteen pairs of curved 
transverse ridges, called pseudo- tracheae. After a somewhat minute 
description of these parts, the writer treats of their functions, retraction, 
protrusion, and homologies.
