L. gozora is the Mexican and Central- American form of L. pseudargiolus, which it 

 closely resembles in the markings of the underside ; but it differs in the tint of the 

 blue of the upper surface, which is considerably darker and more violet, moreover the 

 male has a distinct whitish discal patch: in specimens from Costa Rica and the State of 

 Panama this patch is not nearly so clearly shown nor so constant. 



In Guatemala L. gozora is very common in the highlands, especially in the neigh- 

 bourhood of Duenas, where numbers may be seen on a sunny morning in the rainy 

 season flying round wet places on the roadside.

This is another species of the L. pseudargiolus group, which occurs just on our 

 northern frontier in Sonora. It may be distinguished both from L. gozora and from 

 L. pseudargiolus itself by the darker tone of the blue of both wings. In this respect it 

 resembles L. argiolus, but the wings are greyer beneath without any green tint. 



7. Lycsena cassius.
