and Orthoptera; but its metamorpbosis being that of the latter, 
unless placed in a new order, its station should be in it. 
Rurr 11. When. an insect possesses the characters of one order 
and the metamorphosis of another, in this case it should follow the 
characters. | 
Example.—Myrmeleon and Hemerobius clearly exhibit the cha- 
racters of Neuroptera ; yet their metamorphosis is that of Cole- 
optera, Hymenoptera, and many Diptera, except that their pupa. 
(as is also the case with Hydrophilus) is inclosed in a cocoon spun 
by the anus of the larva. 
On this rule we may observe that, since the perfect state is the 
| Puer consummation of the insect to which all its other states are. 
subordinate and subserve, this state therefore ought to be the 
principal regulator of its station. 
Rurr lll. Where an insect exhibits the metamorphosis of an 
order, or of a section of it, but none of its characters, nor those of 
any other order, it should not on that account be arran ged in ‚such 
order, but on the contrary form a distinct one. ie; 
Example —Vhe metamorphosis of Coleoptera, Hi ymenoptera, and 
many Diptera is incomplete, yet on account of the characters of 
the imago they are properly placed in different orders. This rule 
also applies to Siylops and Xenos. 
Rure 1V. Where the genera which compose an order have inva- 
riably one kind of metamorphosis, no insects that vary from it in that 
circumstance should be placed in it, unless they exhibit a perfect 
agreement with it in characters. ; 
Example.—In the Coleoptera and Hymenoptera the metamor- 
phosis is invariably incomplete, and therefore Forficula, whose 
metamorphosis is semicomplete, and Stylops and Xenos, whose me- 
tamorphosis comes nearest to coarctate, since they differ in seve- 
ral characters from the perfect insects of those orders, should not 
arrange
