AMERICAN LEPIDOPTERA. 205 



A case of this kind is perhaps the most potent argument for hav- 

 ing only a single example as an actual " type." 



Incidentally, the species standing as Agrotiphila velata Strck. in 

 Dr. Dyar's list is wrongly placed. Dr. Strecker described the spe- 

 cies as an Agrophlla, and the name should have been listed under 

 Spragueia on p. 215. 



MAX RUT A n. gen. 



Head retracted ; front flat; palpi small, thinly clothed with hairy 

 vestiture; eyes small, round; tongue wanting; antennae of the $ 

 lengthily bipectinated, the branches setose; vestiture fine hairy, 

 divergent. Thorax stout, clothed with very dense long woolly ves- 

 titure forming no tuftings; legs stout, all the tibiae spinose ; anterior 

 abbreviated, broad, obliquely terminated, inner angle with a long, 

 stout, curved claw, outer angle with a slighter, shorter claw, outer 

 edge with two claws as long and as stout as the one at the angle. 

 Abdomen un tufted. Primaries rather short and broad ; secondaries 

 rather large, proportionately ; venation normal ; vein 5 of the sec- 

 ondaries weak and well removed from 4 on the cross- vein. 



The characteristic features of this genus are its Bombycoid 

 appearance, emphasized by the woolly vestiture, retracted head, 

 lengthily bipectinated antennae and lost tongue, combined with the 

 spinose tibiae and very characteristic armature of the anterior pair. 



Vluili'iitu elingua n. sp. — Head and thorax white, with a pinkish tinge, 

 which becomes marked on the thoracic disc. Primaries with a pinkish flush 

 over a very pale yellowish base, and mottled with a powdering of black scales. 

 The basal line is geminate, blackish, punctiform. T. a. line single, irregular, 

 diffuse, blackish, broken, with a long outward loop in the submedian interspace 

 which replaces the claviforiu. T. p. line single, blackish, diffuse, oblique over 

 the costal region, lost over the cell, lunulate below the median vein. S. t. line 

 a series of dusky points in the pale area. S. t. and terminal spaces more or le.-s 

 black powdered. There is a series of vague terminal dots. The fringes are 

 pinkish, cut with white. Orbicular round, white, obscurely outlined by scat- 

 tered black scales. Reuiform not defined ; a sort of pinkish, upright constricted 

 line in a whitish cloud. Secondaries whitish at base, becoming smoky at the 

 base of the white fringes. Beneath, primaries faintly yellowish ; secondaries 

 white; breast white, woolly; tarsi brown, ringed with whitish. Expands 1.20 

 inches = 30 mm. 



Hab. — Phoenix, Arizona, November 10th and 19th.

 examples have been papered and are somewhat flattened ; one is a
