524 MODERN CLASSIFICATION OF INSECTS.

Macquart forms it into a distinct tribe named Rhyphides. 
Whilst the Molobri, Lestremia, and some other genera exhibit a 
passage from these insects to the Cecidomyides, others equally ap- 
pear to lead to the Tipulides. I have accordingly removed this sub- 
family into its present situation; whereas Latreille placed them be- 
tween the Tipulides and Bibionide. 
The subfamily Trputtpes Mcq. (Terricoles Lar.) is distinguished 
by the large size of the majority of the species of which it is composed 
(fig. 126. 6. Ptychopteryx paludosa ¢ ), having the antenne longer

than the head, simple or rarely pectinated*, but not plumose, and 
composed of from thirteen to sixteen joints; the eyes entire; the 
ocelli obsolete; the front of the head produced into a beak, often 
terminated in a pointed nasus, distinct from the proboscis; the 
palpi long, 4-jointed, and reflexed; the last joint longer than 
the preceding, and often flexible and ringed (jig. 126. 1.+ head

have the antenne pectinated as well as the males. 
+ In fig. 126.1. the dotted part represents the mesothorax, showing the almost 
rudimental collar-like prothorax, behind which is a. spiracle; another spiracle is 
placed close to the base of the balancer of the metathorax, of which the dorsal piece, 
marked x, is here very conspicuous, especially in some species, and might (from 
its situation, occupying the dorsal extremity of the thorax) be supposed to repre- 
sent the scutellum of the following families, It is, however, in consequence of the 
great elongation of the body that the metathorax is here longitudinally developed, 
and hence the part of the dotted mesothorax marked 0, appears to me clearly to 
represent the scutellum of the following families.
