Front with a large hollowed out process with corneous walls with an addi- 

 tional obliquely truncate central process the tip of which is hollowed out, its 

 ventral margin being considerably more produced than the dorsal. Fore tibia 

 rather short, with a moderately heavy curved claw and two very slender spines 

 on the inner side; and a heavy spine or short claw on the outer. Mid tibia 

 moderately spined. Hind tibia with a single spine between the spurs, near the 

 last pair. 



Head, collar, thorax, abdomen and ground color of the primaries pure 

 satiny white. The latter with seven distinct black dots on each, as follows; a 

 transverse anterior row of three, and a medial row of four. Occasionally 

 traces of two minute dots in the basal region. Secondaries; pure white in all 

 specimens before the authors except one in which there is a few fuscous scales 

 thru the costal region. Beneath; primaries suffused with fuscous, paler to nearly 

 white in the anal region. Secondaries ; pure white except for some fuscous scal- 

 ing thru the costal region. 



Expanse; 21-22 mm. 



Uncus with a spoon-shaped tip, from the dorsal surface of which arises 

 a heavy spine. Vinculum pointed. Penis with a large number of heavy spines 

 which appear to half fill the aedoeagus sheath. 



This species is represented in the Barnes Collection from Kerr- 

 ville and Shovel Mt., Texas.

Grotella harveyi, sp. nov. (fig. 2). 



Front and legs similar to septempunctata. 



Head, collar, thorax, and ground color of the primaries pure white, the 

 latter marked with black spots, essentially as in septempunctata but the spots 

 are much heavier, and there is a trace of black checkering in the fringe. The 

 two small basal spots, vestigial in septempunctata, are well marked. Secon- 

 daries; slightly tinged with fuscous, especially toward the costa. Beneath: pri- 

 maries deep fuscous; secondaries white, except along the costal margin which 

 is fuscous, a spot on the discocellular vein and some fuscous shading extending 

 from the costal region into the medial area outwardly from the ordinary spot. 



Expanse: 24-25 mm. (A somewhat larger species than septempunctata.) 



Genitalia: similar to septempunctata but the uncus spine is more apical 

 and the vinculum more rounded, the tip not to as distinct a point.
