 Ph. Ge. vibicaria. Zym?ie.— Ptychopoda ? vibicaria. Steph. Catal. part ii. p. 153. 



JVo. 6735. 

 Wings yellowish ; the anterior with a dot and three strigae purple, the inner one 



the most obscure ; the posterior also with a dot, a single transverse fascia, and 



the margin purple : antennae pale. 

 Caterpillar yellowish-white, with black spots on a pale dorsal Une, with the 



head, mouth, and legs white : it feeds on the broom and mountain hair-grass 



(Aira montana). 



The only examples I have seen of this beautiful species are in 

 Mr. Swainson's cabinet : of their locality he is not aware. 



Genus CXCVI. — Aspilates, TreitscJike. 



Palpi rather long, densely squamous, the terminal joint exposed, acute; triarti- 

 culate, the basal joint rather stout, curved, second subcylindric, terminal 

 slender, elongate-ovate: niaxiUa short, distinct. Antennce short, bipectinated 

 to the apex in the males, the pectinations very short on the three or four 

 terminal joints ; somewhat serrated beneath and thickened at the base in the 

 females: head raihev broad: e^jes prominent: Morax slender, velvety: wings a 

 Uttle expanded during repose, with the hiuder margin entire and rounded, all 

 of nearly similar form ; anterior traversed diagonally by one or more strigae, 

 the posterior one arising at or near the anterior angle ; posterior with a faint 

 striga: abdomen rather long and slender, shorter and stouter in the females: 

 lefrs very long. Larva with 10 legs, somewhat attenuated anteriorly, with 

 two small elevations on the last segment : pupa in a web amongst leaves. 

 The insects of this genus may be known by the integrity of the 

 hinder margins of their wings (all of which are of nearly similar 

 bulk) which are usually of a pale or flavescent hue, with the anterior 

 angle of the primary ones acute, and the disc having one or more 

 very oblique strigte, of which the outer one usually arises at or 

 close to the apex : the palpi are long, with the terminal joint exposed 

 and acute, the legs very long, and the antennae short and bipec- 

 tinated to the apex.
