into two Classes. cxcvii 



Pupa necromorphous : the antennae reflected and immovable, but 

 the legs distinct from the body, and said to be used in walk- 

 ing; having only seen it in spirits, I cannot confirm this: wings 

 rudimental, but very apparent, folded over the hind legs, an 

 arrangement which seems altogether opposed to the alleged 

 power of walking : it changes in the galleries formed by the 

 larvae, and is not enveloped in a cocoon. 



Imago with an ovate head narrowed behind, and long narrow pro- 

 thorax, articulated loosely so as to admit of an easy snake-like 

 motion of the head and neck, whence the specific name of ophi- 

 opsis : eyes hemispherical, lateral, very distant : antennae fili- 

 form, many-jointed; mandibles strong, corneous, curved, and 

 sharply toothed : meso- and metathorax short, transverse, much 

 broader than the prothorax : abdomen soft, terminating, in the 

 females, in a falciform ovipositor : legs simple, almost precisely 

 resembling those of pseudo-tetramerous Coleoptera, the basal 

 joint being long, the second very much shorter, the third deeply 

 cleft and produced into two large lobes, the fourth very short 

 and placed in the cleft, and the fifth moderately long and of or- 

 dinary form : not uncommon in dry woods, and supposed to 

 feed on insects. 



I am only acquainted with one genus, Ra- 



phidia, forming the family Raphidiada:, Newm., 



RAPHiDiiDiE, Leach. 



Characters of Mantispina. 



Larva and pupa unknown. 



Imago with short many-jointed antennae, slightly thickened towards 

 the tip ; corneous acute curved mandibles ; broad transverse head ; 

 distant hemispherical eyes, occupying nearly the whole of each 

 lateral surface ; long, narrowed, and often transversely furrowed 

 prothorax; elongate raptorial fore-legs; broad transverse meso- 

 thorax ; narrow transverse metathorax ; large and conspicuous 

 propodeon; simple middle and hind legs; soft, moderately long, 

 slightly incrassated abdomen, unprovided with any processes 

 at its extremity : wings alike, roof-like, transparent, glittering, 

 beautifully reticulated, no portion of them folded. 



These insects may at present be included in the single family, 



Mantispid.e, Netmn.
