Larentia. 369 



A. — Fore-wings of the male with a strong tuft of hair projecting forwards on the inner 

 margin beneath ; the tip divided by a distinct white line, and nervule 5 of the hind-wirigs rising 

 from tite front half of the discocellidar iiervule. 



* I. L. Reticulata (W. V.). — Fore-wings dark grey, with white nervures, the basal and 

 central areas bounded by white lines, and separated by an oblique transverse band dusted 

 with whitish, and sharply interrupted above the hinder angle. There are also two white trans- 

 verse lines in the central area, and a white dcntated subterminal line, before which the ground- 

 colour is also dusted with whitish ; hind-v.ings grey, with two white transverse lines. Expands 

 about \\ inches. Inhabits Central Europe and Siberia in June and July, but not common. 

 The larva is green, with a red line on the back, and two adjoining white lines ; head green. 

 It feeds on Impatiens noli-mc-tangere in October. When reared in confinement the food-plant 

 must be kept in water. 



B. — Fore-wings of the male with no tuft of hair beneath, and the tip divided by a distinct 

 white line ; hitid-wings pale grey, with one or two whitish curved lines before the hind margin; 

 nervule 5 as in section A. 



* 2. L. Silaceata (\V. V.;. — Fore-wings dark brown, the basal area bordered by one and the 

 central area by two whitish lines, and a band, angular behind, between them. The marginal 

 area is paler and marked with pointed black cones, bordered with white in front, and a black 

 spot on the hind margin below the tip ; the ner\'ures in the marginal area (except in variety 

 Dcflavata, Staud.), and frequently some of those in the central area also, are yellowish ; head 

 dark brown. Expands from i to li inches. Common in Northern and Central Europe, and 

 Northern Asia, from May to July. The larva is green, with paler lines on the back and belly, 

 edged with dusky, or suffused with reddish-brown, with brown longitudinal lines, and a darker 

 line on the back, which divides into three forks above the tail ; head green, brown in front. 

 It feeds on aspen, willow-herb, &c., in June and September. 



3. L. Capitata (Herr.-Schaff.). — Resembles Silaceata, but the head, the middle of the back, 

 and the abdomen are ochre-yellow, and the nervures in the central area are always unicolorous. 

 Expands about i^ inches. Local in various parts of Central Europe in May, June, and 

 August. The larva also resembles that of Silaceata, but is green, with no line on the belly, 

 and with dark lines only on the head. It feeds on Impatiens in July and September. 



*4. L. Suffumata (\V. V.). — Fore-wings brown, with a light strongly-dentated band before 

 the middle, the central area edged with white lines, with a black central spot in the middle, 

 and a double rounded projection, bordered with light brown, behind ; the subterminal line

 central area projects behind, the tip is divided, and tlure is a dark semi-oval spot on the hi?td 

 margin below ; hind-wings paler, with nen'ule 5 rising from the hinder lialf of tlie discocellular 

 nervule. 



*5. L. Prunata (Linn.). — Fore-wings brown, with a zigzag band before the middle, and the 



marginal area paler, the central area with two broad rounded projections behind, and bordered
