terminal joint fully as lono- as second joint, strongly laterally com- 

 pressed, sharp edo'cd in front and Ix^hind, thickened with smoothly 

 appressed scales, which terminate a])ruptly just before apex, leaving 

 the acute tip projecting. Maxillary palpi o])solete. Tongue robust, 

 spiraled, scaled at base. Forewings elongate, about four times longer 

 than broad; costal and dorsal edge parallel; apex obtusely pointed; 

 12 veins, T and !» stalked to costa, rest separate. Hindwings broader 

 than forewings. Costa nearly straight, parallel with dorsal edge; ; 

 apex obtuse, termen hardlv sinuated, tornusand dorsal angle rounded; ; 

 8 veins, 6 and 7 stalked, 5 approximate to 4, 3 and 4 connate, 2 distant. 



Allied to and resembling (Tli/jjhidocetu/Wnh'mghum, but with simple 

 antennie and 12 veins in fore wing, and easily recognized l)y the pecu- 

 liar blade-like labial palpi. 



Besides the species here described there is in the V. S. National 

 Museum a single specimen of another species bidonging to this genus, 

 but not sufficiently well preserved to describe. 



PROSTOMEUS BRUNNEUS, new species. 

 Prostomeus brunneus Busck, Dyar's List Amer. Lep., No. 5646, 1903. 



Antennae dark reddish brown, annulated with white. Labial palpi 

 light brown, mottled with dark-brown and black scales; terminal joint 

 with })ase, an annulus round the middle and apical third black. Head 

 and thorax dark brown. Forewings light straw colored, overlaid with 

 reddish brown; base dark ])urplish brown; along middle of costa from 

 basal fourth to apical third a dark pur})lish brown oblong narrow patch. 

 On the dorsal edge a larger similar patch, projecting up in the light 

 middle part of the wing a boot-shaped figure, with the toe on the cen- 

 ter of the cell, and the heel midway between this and a unicolorous 

 circular spot at the end of the cell. 



The region at tornus is dark brown, and the apical veins are slightly 

 indicated ]\y darker brown streaks. Around a})ex at base of the cilia 

 is a row of dark, i)urplish-])rown dots. Cilia l)rown. 



Hindwings dark steel gray, hghter toward tlie base; cilia a shade 

 lighter. 



Abdomen dark i^urplish fuscous above; entire ))ody light ivddish 

 yellow below. Legs light brown, annulated with l)lack; tarsi black, 

 with tip of each joint white. 



There is some variation in the shade of the brown color in the dif- 

 ferent specimens, some l)eing more reddish, others more yellowish, 

 but the form of the markings seems constant.
