The Species of Known Grotella and Neogrotella from Boreal 

 America are arranged in the Barnes Collection in the following order : 



Groteli-A 



G. septempunctata, Harv. G. vagans, sp. nov. 



G. harveyi, sp. nov. G. binda, Barnes. 



G. sanipita, Barnes. G. tricolor, Barnes. 



G. blanca, Barnes. G. soror, B. & McD. 



G. dis, Grote. G. grisescens, B. & McD. 



G. parvipimcta, B. & McD. G. olivacea, B. & McD. 



G. stretchi, sp. nov. G. citronella, B. & McD. 



Neogrotella 



N. confiisa, sp. nov. A'', mcdiinnoughi, sp. nov. 



A^. spauldingi, B. & McD. 



Grotellaforma, gen. nov. 

 Type: "Grotella" colora, Barnes 



Proboscis fully developed ; palpi moderately and obliquely upturned, the 

 second joint reaching to about the middle of the frons, the third joint short and 

 porrect. Frons with a semi-rounded beak-like prominence, with a corneous 

 plate below. Antennae practically simple in both sexes, minutely ciliated. 

 Thorax clothed with hair and hair-like scales, and without crests. Tibiae 

 scaled, unspined, no claws present. Abdomen, without crests, short, scarcely 

 exceeding the secondaries. Primaries moderately trigonate, the apex rounded ; 

 veins 3, 4, 5 (Cu^, Mg, M^) from near angle of cell, 6 (M^) from upper 

 angle, 9 (R,) from 10 (R^) anastomosing with 8 (R^) to form the areole, 11 

 (Rj) from cell. Secondaries; veins 3 and 4 (Cu^ and Mg) from angle of 

 cell, 5 (M^) from about half way below the middle of the discocellulars, al- 

 most fully developed, 6, 7, (M^, R) stalked half-way to margin from upper 

 angle, 8 (Sc) anastomosing vnih. cell near base only. 



This genus apparently will find a place between Exyra, Grt., and 

 Homologoa, B. & McD. From the former it can easily be told by its 

 shorter body, scarcely exceeding the secondaries (as well as by its 

 general Grotella-like habitus) ; and from the latter by the shorter 

 palpi, with the third joints porrect and short, instead of rather long 

 and upturned. 



Evidently this new genus is another of the links that connect the 



■ Agrotinae, the Acronyctinae and the Erastrianae. At some future 



time Grotella and Grotellaforma may be placed in a separate Heliothid
