Antenna inserted close to the eyes on the crown of the head^ 

 rather short, setaceous, clothed with scales above, pubescent 

 beneath, composed of numerous short joints rather longer and 

 oblong towards the apex, basal joint robust and long, 2nd 

 larger than the following (1, portions of the base and apex). 

 Maxilla as long as the labial Palpi, spiral, rather stout, ciliated 

 at the base, with series of tentaculi at the apex (3). Palpi 

 minute attached to a scape, biarticulate, basal joint producing 

 a few hairs on the inside (3, base of maxilla, a the Palpus). 

 Labial Palpi porrected horizontally, rather divaricating, clavate, 

 thickly clothed with short scales, the apical joint being visible 

 (4), triarticulate, basal joint not short, curved and clavate, 2nd 

 long robust and ventricose, 3rd shorter than the first, slender 

 elongate -conic (4 a). 

 Head rather small, the scales on the crown erect : eyes lateral and 

 globose (7). Thorax globose, trigonate behind. Abdomen rather 

 short and narrow, depressed and tufted at the apex in the males. 

 Superior wings oblong -trigo7iate, costa produced at the base, de?isely 

 clothed with scales forming a shoulder at the middle, posterior mar- 

 gin truncated, the apex slightly acute, posterior angle rounded, the 

 surface more or less clothed with small tufts of scales; inferior 

 wings ample, the margin slightly undulated, the apex a little pointed ; 

 cilia long at the anal angle. Legs, anterior small ; tibiae, anterior 

 very short, ivith a small spine on the inside, middle pair spurred at 

 the apex ; posterior long with unequal sjmrs at the middle and apex : 

 tarsi 5-jointed, basal joint long : claws a?id pulviUi small (8, a fore

Pale dull green ; eyes blackish, antennae dull gray ; abdomen 

 ochreous gray, base of the segments fuscous : superior wings 

 with numerous black spots, 5 or 6 in a line towards the poste- 

 rior margin, with a line of black lunules between the nervures 

 at the base of the cilia and a black dot at the apex of each : in- 

 ferior wings ochreous gray, mottled : cilia pale ochreous, fus-

This pretty genus is most nearly allied to Peronea, but in the

 they are studded with tufts of scales, and the apical joint of the 

 palpi is not concealed. In dissecting I discovered maxillarij
