Neotarche, gen. nov. 



Type: Neotarache deserticola, sp. nov. 



Eyes : smooth, unciliated, round, not large. Proboscis : moderate, func- 

 tional. Palpi : obliquely porrect, extending to near the vertex, first joint broadly 

 scaled below, second and third joints smoothly scaled, the third joint about two- 

 thirds the length of the second. Frons : with a cup-shaped prominence with 

 raised edges, and an additional beak-like central prominence. Antennae : simple 

 in both sexes. Thorax and abdomen : entirely clothed with scales, and without 

 crests. Fore tibia moderate, without spines or claws, fore metatarsus with large 

 heavy claw at tip and two heavy claw-like spines above; other metatarsi normal, 

 not heavily spined. Veination identical with Neogrotella, described herein. 



This genus is tentatively placed in the Barnes Collection before 

 Grotellaforma. This is another remarkable instance of two apparently 

 closely allied genera ; possessing the same veination and frontal struc- 

 ture but apparently v^idely separated by the present classification; 

 genera in which vein 5 (M3) may be called intermediate; and there- 

 fore placed by the presence or absence of tibial spines. Wherever 

 these genera may finally be placed, the present genus will be easily 

 recognized by its veination and frontal structure coupled with the 

 absence of spines or claws on the tibiae and the possession of claws 

 and claw-like spines on the fore metatarsi. 



Neotarache deserticola, sp. nov. 



Palpi : olive-brown, paler basally. Front : pale olive-brown, often nearly 

 white. Collar : similar, slightly darker. Thorax : variable, olive-brown to white. 

 Abdomen : variable, some shade of creamy-olivaceous-brown. 



Primaries : rich olive-brown, with the following white markings on each. 

 The entire hasal region white, or the white stopping at the median vein ; a 

 transverse band present, apparently composed of several fused quadrilateral 

 spots, running obliquely from the costa to the inner margin, that part or spot 

 of the band that crosses the cell is set basad of the remaining portion ; two 

 fused white spots in the reniform-subreniform region; a subterminal white 

 shade band, composed of a spot in apical region, coalescent with a subtriangular 

 spot in the center of the s. t. space, and a disconnected spot in the anal angle. 

 Fringe: white checkered by strips of the olive-brown ground color. Secondaries: 

 fuscous, slightly paler toward their bases; with white, interlined, fringes. Be- 

 neath : cream-color, the markings on the primaries showing thru, but not dis- 

 tinctly. Fringes : as on upper side. 



This species is represented in the Barnes Collection from Hualapai 

 Mts., Mohave Co., Ariz., May 24-31 ; and Dixieland, Imperial Co., 

 Calif., March 1-15, 1922 (O. C. Poling), besides the types.
