Sfi. 1. Humuli. (Ghost-swift.) 



Noclua humuli. Linn. 



Hefiialus humuli. Fabricius, Latreille. 



Inhabits fields. 



Sfi. 2. Ma/i/ta. (Map-wing swift.) 



Phalana ma/i/ia. Donovan. 



Inhabits Britain. Has been taken near Dunstar cas- 

 tle, in Somerset, by Mr G. Sowerby. It may be syno- 

 nymous with Bombyx velleda of Hiibner. 



Sfi. 3. Hectus. (Golden swift.) 



Phalana noclua hecta. Gmelin. 



Hefiialus hectus. Fabricius. 



Inhabits Europe. 



06s. We have in Britain several other species, but 

 their characters are evanescent, and their names have 

 never been determined with accuracy. 



Genus CCCCXXXVIII. Cossus. Fabricius, Li- 

 treille, Cuvier. 



Phaljena Bombyx. Linn. 



Antennae as long as the thorax, setaceous, furnished 

 with a single series of short transverse obtuse teeth. 

 Palpi very distinct, thick, cylindric, and squamous. An- 

 terior wings larger than the posterior. 



Sfi. 1. Lignifierda. (Goat-moth.) 



Phalana (Bombyx) Cossus. Linn, 



Cossus lig?iifierda. Fabricius, Latreille. 



Inhabits Europe. The larva feeds on the internal 

 parts of the willow and ash. The celebrated Lyonett 

 has immortalized himself by his laborious work on the 

 anatomy of the larva, and perfect insect. The caterpil- 

 lar diffuses a scent, by which its residence may fre- 

 quently be made known to those passing such trees as 

 are much infested by it. It remains three years in this 

 state, when it spins a strong web, intermixed with par- 

 ticles of wood, and changes into the chrysalis, which it 

 does in the month of May, and in June the perfect in- 

 sect starts into existence. 



Genus CCCCXXXIX. Zeuzera. Latreille. 



Bombyx. Hiibner. 



Hepialus. Schrank. 



Phalana, (Noctua.) Linn. 



Cossus. Fabricius. 



Antenna setaceous, (in the male pectinated to the 

 middle.) 



Sfi. 1. JEsculi. (Wood-leopard moth.) 



Cossus tescuti. Fabricius. 



Bombxjx asculi. Hiibner. 



Zeuzera esculi. Latreille. 



Phalana asculi. Linn. 



Inhabits Europe. In England it is rather rare, but 

 may be found in St James's Park, in July, if industri- 

 ously sought after. 



Family II. Bombycida. 



Antennae of the males with a double series of pecti- 

 nations. 



Obs. The larvae of this family live on the leaves of 

 trees. Sides of the chrysalis not serrated or denticulated. 



Genus CCCCXL. Saturnia. Schrank. 



Phalaina, (Attaous.) Linn. 



Bombyx. Fabricius, Hiibner, Latreille. 



Wings horizontal. Antennae with the second joint (in 

 the male) bidentate. Caterpillar naked, elongate, with 

 the anal feet distinct, and resembling the middle ones. 



S/i. 1. Pavonia minor. (Emperor moth.) 



Phalana attacus fiavonia minor. Linn. 



Bombyx fiavonia minor. Fabricius. 



Vol. VIII. Part II. 



Inhabits Europe. 



Genus CCCCXLI. Lasiocampa.. Schrank. 



Bombyx. Fabricius, Latreille. 



Superior wings deflexed ; inferior ones reversed. An- 

 tennae of the male very much pectinated. Palpi not pro- 

 duced into a rostrum. Caterpillar naked, elongate, with 

 the anal feet distinct, and resembling the middle ones. 



Sfi. 1 . Quercus. (The egger moth.) 



Phalana bombyx querc&s. Linn. 



Bombyx yuercUs. Fabricius, Latreille. 



Inhabits Europe. The larva feeds on the bramble. 



Obs. The following indigenous species of Fabrician 

 Bombyx are referable to this genus, viz. 2. Trifolii ; 3. 

 Rubi ; 4. Cratagi; 5. JVeustria ; S.Pofiuli; 7 . l.anes'tris. 

 The four last are distinguished by their palpi, being 

 more hairy than the rest, and may be considered as 

 forming a subdivision. 



Genus CCCCXLII. Bombyx. Fabr. Latr. Schrank. 



Superior wings deflexed, inferior ones reversed. An- 

 tennae of the male very much pectinated. Palpi pro- 

 duced into a rostrum. Caterpillar naked, with the anal 

 feet like the middle ones distinct. 



Sfi. 3. Quercifolia, (lappet moth.) 



Phalana 6om6yx quercifolia. Linn. 



Bombyx yvercifolia. Fabr. Latr. 



Inhabits Europe. 



Obs. The following indigenous Bombyces of Fabricius 

 belong to this genus, ^iz. 2. Rotatoria ; 3. Pint. 



Genus CCCCXLIII. Lakia. Schrank. 



Phaljena (Bombyx.) Linnaexis. 



Bombyx. Latreille, Fabricius. 



Wings deflexed, the under ones entirely covered by 

 the upper ones. Antennae of the male much pectinated, 

 or much ciliated. Caterpillar naked ; the hinder feet 

 distinct like the middle ones. 



Sfi. 1. Disfiar, (gipsey moth.) 



Phalana disfiar. Linnaeus. 



Bombyx disfiar. Fabricius. 



Inhabits Europe. 



06s. This genus requires examination. The follow- 

 ing species are found in Britain: 2. Monacha, (black 

 arches); 3. Fascelina, (scarce tussock); 4. Pudibunda, 

 (common tussock); 5. Reclusa, (small chocolate-tip); 

 6. Curtula ? (large chocolate-tip) ; 7. Roboris ; 8. Tri- 

 macula, (Donovan) ; 9. Caruleocefihala. (figure of eight) ; 

 10. Coryti, (nut-tree tussock); 1 1. Ziczac, (pebble pro- 

 minent) ; 12. Dromedarius, (iron prominent); 13. Bucc- 

 fihala, (buft-tip) ; 14. Tritofihus, (aspen prominent); 15. 

 Trefiida, (swallow prominent); with a few other species 

 whose names are not yet determined. Bombyx viskolora 

 of Fabricius, (the Kentish glory,) forms a peculiar ge- 

 nus, viz. Doi-villia. Leach. 



Genus CCCCXLIV. Cerura. Schrank. 



Bombyx. Fabricius, Latreille. 



Phaljena, (Bombyx.) Linnaeus. 



Antennae in both sexes pectinated, and gradually ac- 

 cuminate. Caterpillar, with the anal feet transformed
