lice belong to this group, and thus represent the plant-lice among 
the Homopters.—(3) The Perlideans, semiaquatic and prematura- 
tive species, which are Trichopteroid (or like the Phryganeans) 
in the form of the wings, in the larve being not only aquatic but 
also living in a sheath, and in the adult eating little or nothing. 
hus each subdivision of the Amplipens, the Lepidopterous, 
Remaphnvece and Trichopterous, appears to be represented in 
the subdivisions of the Amplipenniforms. 
The subdivisions of Attenuates or Neuropters deduced are 
the following: 
1. APIPENNIFORMS. 
1. Termitideans, or Hymenopteroid group. 
2. Panorpideans, or Dipteroid group. 
8. Aphanipteroid. Group unknown. 
2. AMPLIPENNIFORMS. 
1. Plannipennians, or Lepidopteroid group. 
‘2, Psocideans, or Homopteroid group. 
3. Perlideans, or Trichopteroid group. 
3. Peratrenvates or Typrca, Nevuroprers, 
1. Libellulideans. 
2. Hphemerideans.
