Front essentially as in septempunctata, the central prominence possibly 

 not as much produced. Fore tibia with a heavy inner claw and three or four 

 spines, the outer side with a short spine only. Mid tibia with about four spines 

 on upper half only. Hind tibia unspined (?). 



The original description, plus the figure in the "Contributions" will serve 

 to identify this insect. The brown abdomen may be the result of staining, but 

 apparently is not. Most of the specimens of hinda appear to have a brown 

 abdomen due to staining, but in fresh specimens the abdomen matches the thorax. 



The female type is a unique, so the genitalia are unavailable for study. 

 The insect certainly seems closely associated v/ith hinda and tricolor, but is 

 abundantly distinct. It differs from the former in the more even t. p. line, the 

 presence of an apical brownish-black patch, and patches near the termination 

 of veins 2 and 3 (CUg and Cu^), and the fact that the brownish-black checker- 

 ing of the fringe does not extend backv/ard into the terminal area of the wing 

 itself as it does in females of hinda. The secondaries are much more heavily 

 suffused with fuscous, being slightly pale only along the basal portion of costa, 

 and the lower basal half of the wing. A very broad deep-fuscous band along 

 the outer margin, nearly extending inward to the middle of the wing, suggests 

 the same band present in many species of Oncocnemis and is not present in any 

 other Grotella known to us.

Front essentially as in septempunctata. Fore tibia with an outer claw- 

 like spine and a very heavy inner claw, but the authors are unable to find any 

 other spines. The mid tibia spined. Hind tibia unspined (?). 



Head, thorax, and abdomen the same creamy-olivaceous color as the costal 

 region of the primaries. Collar with at least some lemon coloring, usually pro- 

 nounced ; the disconcolorous collar a unique character in the genus as far as 

 known to the authors. Primaries : with the ground color smoky-brown, heavily 

 dusted with creamy-olivaceous scales, the ground color plainly showing only in 

 the medial area in the space from below the cell to the inner margin; else 

 showing faintly thru the olivaceous dusting especially where the scales have 

 been rubbed. The olivaceous shade is strongest on the costa, being quite creamj' 

 in tone. Fringe: pale creamy-olivaceous. Secondaries: light smoky-brown, the 

 fringes somewhat paler. Beneath: prim.aries, deep fuscous; secondaries: pale 

 cream color without markings. Fringes somewhat paler. 



Expattse: about 21-22 mm.
