A REVISION OF THE NOCTUID MOTHS HERE- 

 TOFORE REFERRED TO THE GENUS 

 GROTELLA, HARVEY 



Grotella, Harvey. 



Type: Grotella septempunctata, Harv. 1874, Harv., Bull. BuflF. Soc. Nat. 

 Sci., II, 278, septempunctata, Harv., sole species and therefore type. 



Proboscis fully developed; palpi short, the second joint upturned and 

 moderately scaled, the third porrect. Frons with a large hoUowed-out process 

 with corneous walls, and with an additional obliquely truncate central process, 

 the tip of which is hoUowed-out, its ventral margin being produced more than 

 the dorsal. Eyes smooth, not ciliated, Antennae simple, in both sexes. Fore 

 tibia with at least a long curved claw on the inner side and shorter claw or 

 heavy spine on the outer. Mid tibia spined. Hind tibia usually with a spine 

 between the spurs, often small and difficult to see. Abdomen and wings 

 smoothly scaled. Primaries; veins; 3 (Cu^) from before angle of cell, 5 (M^) 

 from above angle, 6 (M^^) from upper angle, 9 (Rg) from 10 (Rg) anastomos- 

 ing with 8 (R^) to form the areole, 11 (R^) from cell. Secondaries; veins 3 

 and 4 (Cu^ and Mg) from angle of cell, 5 (M^) from about a third below the 

 middle of the discocellulars, almost fully developed, 6, 7, (M^, R) shortly stalked 

 from upper angle. 



Genitalia : a paired, heavily chitenized organ arising from the dorso-caudal 

 margin of the valves, present, extending to near the base of the uncus and sup- 

 porting the aedoeagus. This may be a part of the anellus or juxta. Penis 

 bearing at least some heavy spines, usually a great many, (cornuti of Pierce). 

 Uncus usually with the tip broadened, spoon-shaped, and bearing a spine at or 

 near the end. 



The armature of the tibiae is variable, but probably more or less constant 

 specifically. The small slender spines on the fore tibiae above the spurs are 

 often difficult to see, as is the presence or absence of the single spine between 

 the spurs on each hind tibia. The authors desire to point out that the small 

 spines are easily broken, and also that they are frequently so small and so inter- 

 mingled with the tibial vestiture that it is practically impossible to tell the 

 correct spinulation. The number of spines on the fore tibiae and the presence 

 or absence of spines on the other tibiae, as seen thru an ordinary binocular 

 microscope, is listed under each species. 



The frontal processes are often slightly different between species and 

 usually rather constant within a given species. This character is too compara- 

 tive to be of much use except as a check on identifications. 



The types of all species considered are in the Barnes Collection 

 with the exception of septempunctata, dis, and "Cisthene" lactea, the
