170 STATES OF INSECTS. (Larva.) 
sent are equally so. The Libellulina MacLeay (whose 
metamorphosis that gentleman has denominated swb- 
semicomplete, a term warranted by their losing in their 
perfect state the mask before described*) in their oral 
organs, particularly by their galeate maxilla and distinct 
ligula», have some relation to the Orthoptera, the proto- 
types of whose larvee we have found amongst the Crus- 
tacea : probably, therefore, those of the tribe in question 
lurk in that class; a suspicion that receives strong con- 
firmation from the larva of Agrion*, which in its ta- 
pering body and anal natatorious laminz represents a 
shrimp. The larve of that very peculiar and distinct 
tribe, the Ephemerina, appear to be intermediate between 
the Stomapodiform and Thysanuriform types. ‘Their na- 
tatory respiratory abdominal laminze seem copied from 
the former, and their anal diverging sete from the latter*. 
The Myrmeleonina, as well in their general form as in 
their motions and habits, present a most singular analogy 
with the tribe of spiders, as does also in some respects that 
of Cicindela. With regard to Panorpa, which Mr. Mac- 
Leay remarks is related to Myrmeleon ®, and is a most 
ferocious insect ‘, as its larva has not yet been discovered, — 
nothing certain respecting its analogical form can be 
asserted ; but should it, like the male fly, represent the 
scorpion, both orders of Arachnida will have their re- 
presentatives in the class we are considering. The Cory- 
dalina, as far as the larva of Hemerobius instructs us, is 
Chilopodiform, but with a tendency to the Arancidiform
