32 PACKARD, NOTES ON THE 



edge, which in Procris and Ino as well as Zygcena, is angulat- 

 ed in the middle, thus giving the wing in those genera a squarish 

 appearance. The nervules are longer and more parallel with 

 the costa. When expanded the secondaries only reach to the 

 basal third of the abdomen, while in Procris they reach to the 

 basal two-thirds. The abdomen is remarkably square, a little 

 flattened and slightly spreading in the female of Uarrisina, 

 in Procris it tapers gradually to an obtuse point. 



Dr. Harris has given ample details of the history and trans- 

 formation of the americatia, and it is most appropriate to 

 dedicate to his memory the genus to which it belongs. 



Dr. Fitch also gives the following summary of its aspect 

 and habits. " In August standing in a row side by side on 

 the under surface of the (grape-vine) leaf, eating its edges, 

 and leaving only the coarse veins, little yellow worms about 

 .60 (inch) long and slightly hairy, with a transverse row 

 of black spots on each ring ; forming their tough oblong oval 

 cocoons in crevices ; the moth appearing the following July."

Harrisina Sanborni nov. sp, Another interesting species 

 belongs here, kindly loaned me by Mr. Sanborn, to whom 

 it is dedicated. It is half the size of H. americana^ has 

 shorter wings ; primaries with a more convex costa, while 

 the costa in the secondaries is straight. The neuration also 

 differs. The costal nervure goes more rapidly towards the 

 i costa, and. in fact the whole costal area is broader, the median 

 nervures are more angulated at their origins, and are wider 

 apart, with, consequently larger interspaces than in H. amer- 

 icatia. The abdomen is much shorter. The antennas likewise 

 differ in having stouter pectinations. 



It would at first, from the similarity of its colors, be easily 

 mistaken for a dwarfed americana, but it differs throughout. 

 From Dr. Clemens' A. coracina, of which unfortunately no 

 measurements are given by that author, it will be known by 

 having a saffron collar which is however smaller than in amer- 

 icana. 



Our species is wholly deep blue black, the tinge being decid- 

 edly bluish and not greenish as in americana. Length, fe- 

 male. 20 ; Exp. wings, female, .61 inch. 



We would place after this genus, Pyromorpha dimidiata 

 H.-Sch., Exot. Schm. 1855, of which Malthaca perlucidula
