the costal margin of the tegmina largely edged with the same. 

 Whether similis should be considered a distinct species or merely a 

 chromatomorph of higuttata we cannot say at present, an uncertainty 

 shared with Brunner and Saussure, but it is our opinion that, ten- 

 tatively at least, it should be considered worthy of specific rank. 

 Aside from the color features the female appears to differ in the teg- 

 mina being longer than in higuttata, and of sufficient length to cover 

 half of the dorsum of the abdomen. All the material we have re- 

 ferable to similis is of considerably larger size than that referred to 

 higuttata, also much surpassing the measurements given in both 

 of the original descriptions, but this, we feel, may ]je individual or 

 geographic in character.

It may be necessary in the future to remove this species from the 

 genus Monastria, as there is a very great amount of difference between 

 M. higuttata, the type of Monastria, and this species.

Amazons. One male. [A. N. S. P.] 



As pointed out elsewhere^ we consider this name to represent a ■ 

 species well separated from H. laevigata Burmeister; with which it 

 is usually synonymized. 



^ We have recently had occasion to examine the type of Scudder's Hormetica 

 advena (Proc. Davenp. Aoad. Nat. Sci., VIII, p. 94) described from a specimen, 

 unquestionably introduced, taken at Belmont, IVIassachusetts. It is a well 

 marked species, characterized by lateral tegmina such as are found in Parahor- 

 metica, but having strongly developed tarsal arolia as in Hormetica. Its closest 

 relationship is, however, not with verrucosa as stated by Scudder, but with sah- 

 cincta Walker, from which it differs in the tegmina being lateral instead of quad- 

 rate and attingent, in the pronotal "horse-shoe" being of relatively less area, 

 less pronounced and differently colored, and in the pronotum being in general - 

 less compressed and less vaulted. Both species have shining black abdomens,, 

 margined laterad with ochraceous and the tegminal color similar.
