Hah. 1 Panama (Mus. Genavense). 



Tribus PANESTHnOE. 

 This Tribe is represented in North America by the genus Cryptocercus, Scudd., and 

 in South America by the genera Dasyposoma and Parahormetica. No species has yet 

 been detected in Central America. 



Fam. MANTID.E*. 



This family f has been divided into " tribes " by H. de Saussure in his ' Melanges 

 Orthopterologiques.' Stal has since proposed rather different divisions, introducing 

 useful modifications in the former system, but also some others which we cannot accept. 

 The classification of Brunner de Wattenwyl is a modified combination of these systems, 

 and as this seems to be the most correct we have adopted it here. 



Nomenclature of the pronotum, head, and legs. 



Peonotttm : The pronotum of Mantidse forms over the insertion of the anterior coxae a dilatation, some- 

 times altered in appearance when the margins of the pronotum are extended into lamellar wings (Ohoeradodis, 

 Rhombodera, Deroplatys). The part of the pronotum extending behind the dilatation (pars postica) is the 

 shaft or stem (scapus) ; that extending before the dilatation (pars antica) and joining the head is the collar 

 (eollum). This last part has at its base a transverse groove (sulcus supra-coxalis), which breaks at a right angle 

 on each side, and frequently extends forwards in a direction parallel to the lateral margins of the collar, its 

 two lateral branches joining again anteriorly, separating the borders of the collar from its disc. 



Head : The parts of the head are : — Over the labrum the clypeus, in the form of a reversed trapezium, 

 divided by a transverse cannula. Over the clypeus the facial shield (scutellum faciale), very characteristic in 

 its various forms. Above this comes the forehead (from), with the ocelli ; over the forehead the vertex, 

 which is either at the top of the face or thrown back to the occipital part of the head, when the frons 

 becomes oblique. (Hieeodtjla.) 



Legs : The anterior pair of legs and their armature present important characters for the distinction of the
