206 EXOTIC NEUROPTERA. 



third is interstitial with end of the cell ; and in other species 

 this character is still more variable. Therefore the two 

 genera should be united, and the Anchieta of Navas is also 

 a synonym as Enderlein has already put it. 



Ditaxis and Drepanicus are very close together, and per- 

 haps identical; Molinella of Navas is the same as Dre- 

 panicus. 

 1 Front tarsi with one claw ; front coxae divided more or less plainly 



into two parts MANTISPINAE-2. 



Front tarsi with two claws : front coxae entire. 



ANISOPTERINAE-S. 



2. Second anal vein of fore-wings forked ; cubitus in hind-wing not 



bent toward anal ; radial cells long; pronotum short. 



Eucliinacia. 



Second anal not forked 3. 



3. In hind-wings the cubitus bends down towards the anal, touching 



the anal or connected to it by a very short cross-vein 4. 



In hind-wing the cubitus does not perceptibly bend down toward 

 the anal ; radial cells long and with several branches to each. 



Cliinaciella. 



4. Pronotum with hairs, not or barely wrinkled ; antennae more than 



twice the diameter of the basal joint apart at base ; prono- 

 tum very slender Mantispa. 



Pronotum without hairs, but very plainly transversely wrinkled ; 

 antennae not twice the diameter of basal joint apart. 



Maiitispilla. 



5. Prothorax closed beneath ; three closed radial cells ; front tarsus 



without spine near end 6. 



Prothorax open beneath ; two closed radial cells ; front tarsus with 

 spine above near end 10. 



6. Median vein of fore-wings united for a short distance with the 



radial sector ; stigma barely longer than broad. 



Caloniantispa. 

 Median vein not united to the radial sector; stigma longer 7. 



7. One series of gradate veins 8. 



Two series of gradate veins ; many costal cross-veins 9. 



8. The median vein of fore- wing appears forked, a long cross-vein 



from the fork to the cubitus ; costal area narrow. 



Theristria. 

 The cubitus of fore-wing appears forked, or rather a short cross- 

 vein from fork to the cubitus ; costal area normal. 



Gerstaeckerella. 



9. Chilian species, green in color Drepanicus. 



Australian species, not green Ditaxis.
