long; from vulva to anterior end of segment VII (as mounted) mem- 

 branous and covered v^^ith small microtrichiae (not indicated in figure), 

 then becoming heavily sclerotinized and appearing much tM^isted on 

 account of spiral ridges of this sclerotinization ; near entrance of ductus 

 seminalis again becoming abruptly membranous. Bursa copulatrix and 

 duct leading out to just past the ductus seminalis membranous; a tri- 

 angular patch of minute microtrichiae at point of constriction (area of 

 stipple in figure). 



Zale sp., viridans group

This is the first record of any species of this genus being taken in the 

 Galapagos Islands. Unfortunately, this is one of the most difficult genera 

 of the family Phalaenidae. All attempted revisions are unsatisfactory. 

 The single specimen available falls into the complex grouped under the 

 name viridans Gn. in the U.S. National Museum. It does not match per- 

 fectly any specimen in the long series at the U.S.N.M., but seldom do 

 any two specimens from different localities agree perfectly in this group. 

 The male genitalia (pi. 30, figs. 4-9) differ in some respects from slides 

 of Mexican specimens of viridans auct. in the author's collection. Chief 

 among these genital differences is the small membranous lobe on the left 

 valve ; in my Mexican specimens this lobe is represented by only a hump 

 or even a flat membranous area. Other differences of questionable con- 

 stancy are found in the details of shape of both valves.
