170 STATES OF INSECTS. 



j)hipodiform Crustacea are represented extremely well by 

 Gryllus L., and the Stomapodiform, particularly Squilla 

 Mantis, by Mantis. The resemblance in this last instance 

 is so very striking, that it cannot escape the eye of the 

 least intelligent observer. Orthopterous insects may per- 

 haps one day be discovered analogous to the two other 

 crustaceous orders, the Decapods and Branchiopods ; but 

 at present I know of none of that description. 



Hemiptera. The larvae of this order, which in general 

 resemble the perfect insect, except that they have no 

 wings, seem most commonly to belong to the Anopluri- 

 Jbrm type a ; but the Aphides, Chermes, and Thrips may, 

 I think, be regarded as more analogous to the genera 

 Podura and Sminthurus in the Thysanura b . I have some 

 suspicion that the Nepidce, Naucoris, and the remipedes, 

 Notonecta, Sigara, &c. may find their prototypes amongst 

 the Crustacea ,■ but my confined knowledge of the latter 

 does not enable me to point to any individual genera or 

 tribes that they may be presumed to represent. 



Neuroptera. As the kinds of larvae of the different tribes 

 composing this order, as it now stands, are very various, 

 it is to be expected that the analogical forms they repre- 

 sent are equally so. The Libellidina MacLeay (whose 

 metamorphosis that gentleman has denominated sub- 

 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 d , have some relation to the Orthoptera, the proto- 

 types of whose larvae we have found amongst the Crus-
