434 ON THE TRIBES 



insect, which seems to occupy nearly the same place 

 among the Mandibulata, as a Thrips among the Haus- 

 tellata, and which he calls Panorpa hyemalis : " Antenna, 

 corpore breviores. Rostrum corneum cylindricum thorace 

 longius. Thorax teres rugosus. Ala maris 4. abdornine 

 breviores apice incurvo subulato fusca. Abdomen maris 

 muticum; femina ense terminali." The next time we 

 have an original observation on this insect is in Panzer's 

 Fauna Ins. Germ, under the title of Gryllus probosci- 

 deus! " Singular e admodum insectum, quod ad Gryllos 

 Fab. {Acridina Lat.) propter antennarum situm atque 

 fabricam habitumque pene cum Gryllis convenientem re- 

 legavi. Mir a fabrica oris, quippe proboscide ad instar Trux- 

 alidum instructa! " We then find it in the French Ency- 

 clopedic again under its original name, Olivier concluding 

 his description of it with the following words : " Cet in- 

 secte n'appartient certainement a ce genre (Panorpa); il 

 paroit en former un qui devra etre place peut-etre par-mi 

 les Orthopteres." Lastly, we have it as the Neuropterous 

 genus Boreus of M. Latreille, of which the characters are, 

 the first segment of the trunk enlarged into a thorax, and 

 the abdomen of the female terminated with an ensiform 

 appendage ; in both which respects it evidently leaves the 

 true Panorpa for Raphidia. We are now very near, if 

 not already arrived at, the osculant point of the circles of 

 Orthoptera and Neuroptera. 



Another insect, forming the modern genus Mantispa, 

 which with Linnaeus and Scopoli was a Raphidia, but 

 which Fabricius and Pallas esteemed a Mantis, an insect 

 which M. Latreille, in the Genera Insectorum, made Or- 

 thopterous, in the Considerations generales Neuropterous, 

 which in the Rcgne Animal he again restored to the Or-
