102 OELECHID.E. 



eain vena miica, c vcnula transversa (vol vena apicalis simplex in 



apieem exit, infra earn veivce duta c vcnula transversa) ; vena niediana 



trifida. 



Head smootli. Ocelli none. Antenna; with the joints thickly set. 

 Tongue of moderate length, clothed with scales. Maxillary palpi very 

 short. Labial palpi moderately long, or long, reflexed ; the second 

 joint beneath slightly broader, with appressed scales, hardhj resembling 

 a brush, sometimes quite smooth ((?. ncEmfereJlci) ; the third joint slen- 

 der, smooth and pointed. Anterior wings oblong or elongate, with 

 moderately long cilia ; tJie posterior loiuys trapezoidal, dightlij or deeply 

 emanjinate beloio the apex. In the anterior wings the furcate apical vein 

 terminates in the costa before the apex ; below it are five veins from 

 the discoidal cell; more rarely {G. leucatelta, hifractetla, etc.) the apical 

 vein is trifid, the third branch running into the hinder margin below 

 the apex, and below it are only four veins from the discoidal cell. In 

 the posterior wings the apical vein is furcate, terminating above and 

 below the apex ; below it is only one vein from the transverse vein ; or 

 else (costella, iricolorella, etc.) the apical vein is simple, and below it 

 are two veins from the transverse vein ; the median vein is tritid. 



A genus of great extent^ and comprising a great diversity of 

 species, but which unfortunately we cannot subdivide into other 

 genera. In this country we have no less than ninety-five s])ecies, 

 and probably as many more are known on the continent. 



As might be expected, there is considerable diversity in the 

 habitats of the species ; some frequenting stems of trees, otlier 

 taking slielter in the grass. All the species are extremely active 

 in the perfect state, and tlicir flights are only for a short distance 

 at a time; when they settle, they frequently immediately seek a 

 place of concealment, whereby the collector is often baulked in 

 his pursuit of some rarity. The habits of the larvrc are extremely 

 varied : that of G. TopnleUa rolls up the leaves of the poplar and 

 sallow much like a Tortrix-X^x^'A ; that of (/. rnfescens twists up 

 grass-leaves, bleaching them by eating them half through ; that of 

 G. MalreUa feeds in the seeds of tlic hollyhock, proceeding re- 

 gularly through tlic circular row of seeds, much to the annoyance 

 of the liorticultui'ist ; \X\i^i Q>i G. iiiutlucUa enters the unopened 

 llower-buds of the furze and broom, and devours the incij)ient 

 fructification of the flower, after having eaten which it proceeds to 

 the next flower and repeats the process; that of G.diJJiiiis, which 

 is extremely active, feeds near the root of the dwarf sorrel [Bnmex 

 Acetosel/a); that of G. aenni'inaleUa mines in the leaves of the 

 thistle ; that of G. notatdla burrows in the woolly substance on 

 the underside of the leaves of the sallow ; that of G. scriptclla 

 turns down a jjiece of maple-leaf, fastens it in its position l)y se- 

 veral silken cables, and eats the leaf ludf through; that of G.fra-
