NEW NEUROPTEROID INSECTS, NATIVE AND EXOTIC. 

 BY NATHAN BANKS. 



The descriptions of the following new species have accumulated 

 during the past year, based mostly on accessions to my collection, 

 but the types of some (indicated in text) are in other collections. 

 I have included a table to the genera of Myrmeleonids known from 

 the Indo-Australian region.

 pale median stripe; thorax black; abdomen brown; setae pale, tips 

 of joints dark. Legs pale brownish. Wings faintly fumose, venation

 to subcosta, radius or its branches, the costal margin concave at 

 humeral cross-vein. Female ventral plate with a median excision,
