The preceding species ends the division of the long-palpi group 

 with bifurcate Uncus ; the following species have a simple narrow point- 

 ed Uncus and show great similarity in general type of genitalia to the 

 albifasciata group of short-palpi species where we imagine their real 

 relationship will be found to exist.

We have nothing further to add to Mr. Swett's treatment of this 

 species (C. Ent. 47, p. 9) which is readily recognizable; the Uncus is 

 short with a moderately broad base and the Aedoeagus is armed with a 

 bunch of long spines. 



We have before us a small series of specimens from Arizona 

 which appears to be a race of this species ; in general color they 

 approach closer to the form taylori Swett than to the typical form, one 

 of the 9 's however showing a considerable amount of green ; the 

 race is characterized by the reduction of the cross bands 4 and 5 (post- 

 median and subterminal) ; tlie former is closer to the latter than is usu- 

 ally found in the typical form, leaving the median space broader ; it is 

 also rather evenly dentate or crenulate, especially below the costa, a 

 feature which occasionally is found in the type form but which is 

 usually hidden in the broad blotches. The Uncus has the basal portion 

 rather less broad, the whole organ gradually and evenly tapering, 

 whereas in the type form the broad base is rather sharply separated 

 from the narrow apical section ; the spines on the Aedoeagus seem to 

 show a difTerent arrangement but this may not be constant in a series 

 of slides. We propose for this race the name morosata, our types 

 being 5 3,3 2 from Redington, Arizona, one of the former in the 

 Collection of the American Museum. 



Hydriomena barnes.^ta Swett. (PI. V, Fig. 10; PI. X, Fig. 5). 



The type of genitalia shows that this species is correctly placed 

 next to speciosata; the narrow portion of the Uncus is considerably 

 longer than in speciosata and the armature of the Aedoeagus consists 

 of a small patch of minute spines, otherwise the genitalia are very 

 similar. The species seems to be widely distributed in Southern 

 Arizona ; we have it from various localities in Cochise Co., from the 

 White Mts. and also from Ft. Wingate, N. Mexico, all our dated 

 material having been taken in June or July.
