Genitalia: As described under the generic heading, and shown in the 

 figure. 



This species is represented in the Barnes Collection from the type 

 localities only. 



Type localities and number and sexes of types: 



"Type" — Redington, Arizona ; the specimen figured in the "Contributions" 

 as listed above. Hereby made the lectotype. { $). 



"Type" — Redington, Arizona, ($), an apparent true cotype, due to error 

 in sexing the types, which must now be relegated to mere paratypical status.

Hampson's figure, supposedly of the type, matches neither the 

 original description, nor the figure given by Stretch in the Journal 

 of the New York Entomological Society; both of which certainly 

 characterize the habitus of a Grotella. However, no known Gro- 

 tella fits either the description or the figure. The black spots on the 

 primaries are quite characteristic and stable within each species of 

 Grotella, but both the original description and the figure of lactea 

 call attention to three black spots on the costa, one of which is in the 

 medial region, the distal spot being in the t. a. region. This would 

 seem to exclude all of the white winged species with the small black 

 spots on the primaries, known to the authors. Of course, lactea may 

 belong to the Arctiidae, or to the Erastrianae ; but the general habitus 

 presented by Mr. Stretch's figure so strongly resembles a Grotella 

 that it is considered best to include the insect in this work as an un- 

 known. For the sake of convenience, the original description is 

 printed below. 



"Cisthene lactea. Eyes black. Antennae brown. Palpi black. Tongue 

 as long as the body. Entire insect otherwise white above and on the body 

 parts, the underside of the wings being smoky, especially the primaries, on 

 the latter are usually six small black spots, three on the costa equally spaced ; 

 one just outside the discal cell, and two in the space below the median vein, 

 one of them being near the base, and the other near the outer margin.
