NEUROPTERA, 1/9 



Living specimens of these insects have been sent to Aus- 

 traha by our government in the hope of introducing the 

 species there, and thus doing something towards repaying 

 the debt that we owe that country for the AustraHan Lady- 

 bug, which has rendered us great service in the destruction 

 of the Cottony-cushion Scale in California. 



The family is represented by two genera, Raphidia (Ra- 

 phid'i-a) and Inocellia (In-o-cerii-a). Li the former there 

 are three simple eyes on the top of the head between the 

 compound eyes ; in the latter these ocelli are wanting. 



Family Mantispid^ (Man-tis'pi-dae). 



The Ma7itis-like Neitroptera. 



The members of this family are even stranger in appear- 

 ance than the Raphidians. Here, as in that family, the 

 prothorax is greatly elongated ; but the members of this 

 family can be easily recognized by their remarkable fore 

 legs, which are greatly enlarged and resemble those of the 

 Praying Mantes in form (Fig. 

 2 1 8). These legs are fitted for 

 seizing prey; and, in order 

 that they may reach farther 

 forward, they are joined to 

 the front end of the long pro- 

 thorax. In the adult state 

 these insects are predaceous; 



while the larv^, so far as is p,^. ,,z.-Mantispa, in the specimen 



known, are parasitic in the ^i'^^^^^hJT^^'lo sZ'^\^:i^^ 

 egg-sacs of spiders. ^^ '^^ p^^'"- 



Five species of the family are known from the United 

 States ; four of these belong to the genus Mantispa (Man- 

 tis'pa) and one to Sy^nphasis (Sym'pha-sis).
