 the intermediate and posterior femora; coxae blackish-fuscous. Ab-

 I possess two males and five females, from California, sent by 

 Mr. Henry Edwards ; the females vary very mnch in size and 

 comparative robustness, the larger individuals having the legs 

 and antennae darker ; but all seem to pertain to one species. It is 

 is a true Notidohia, as is the following species, and in structure 

 is quite identical with the typical N. ciliaris of Europe.

 hirsuta ; antennae palpique fusci. Pedes flavo-fuscescentes, anteriores 

 obscuriores. Abdomen fusco-nigrum, nigro-hirsutum : appendices 

 inferiores magnae, latae, excisae, supra in dentem incurvatum intus 

 productae. Alae fuliginosae, sparse brunneo-pubescentes : anticarum 

 pterostigma flavum (c?). 



Long. corp. 3 lin. (=6| mill.) ; exp. alar. 9| lin. (=20 mill.).
