teeth ; while lower down on the sides of the body are four tubercles, 

 being the remnants of the two middle pairs of prop legs. The remain- 

 ing rings are less angulated. The tip of the abdomen is obtusely 

 conical, ending in four tubercles, the pair above long and truncate, 

 those below broad and short. On the under side are two minute ap- 

 proximate tubercles. The whole chrysalis is of a dark mahogany 

 brown, with the surface finely granulated."

The proper location of this somewhat anomalous genus has been 

 the subject of extensive discussion. Dr. Harris located it near Noto- 

 donta, while Walker refers it to the NoduidcE. Mr. Doubleday in his 

 letters to Dr. Harris, states that Westwood saw in its structure certain 

 affinities with Callimorpha, while Boisduval transferred it to the Zygce- 

 nidce. The notes on the Family Zygoenidos by Dr. Packard, from 

 which the above generic characters are extracted, were written with the 

 object of showing the "systematic position of the genus, and are well 

 worthy the careful stud}- of Entomologists. The two Eastern species 

 are well known ; a third from California must be added to the list. 

 They may be tabulated thus :
