— j>hili 2 )pus (Fab.); Amhhjpodia (Doubl.) is represented by speci- 
mens of the Ceylonese forms of lolaus loiiginus (Fab.) and pscuclo-lonr/inus 
(Doiibl), which Butler regards, in opposition to Ilewitson, as distinct 
species, and of which he gives characters. Butler figures Myrina freja 
(Fab.), 1. c. p. 36, fig. 1, and its local form (Jaff'f'ct)} fig. 2 ; also lolaus 
jysmdo-longinus (Doubl.), 1. c. fig. 3. 
Theda. Hewitson (111. Dium. Lepid. part 3) cites 164 species of this 
genus, of which a largo proportion are described as new. He figures the 
following known species of the genus \ — T. Uncus (Fab.), var., pi. 33. figs. 
60, 61 ; T. site (Boisd.), pi. 46. figs. 193-196 ; T. damon (Cram.), pi. 37. 
fig. 100; 2\ poiihetes (Cram.), pi. 32. fig. 47 ; T. atnhrax (Wostw.)., pi. 41. 
fig. 160 ; T. crix (Cram.), pi. 46. figs. 203, 204 ; T. tephreem (Hiibn.), pi. 43. 
figs. 172, 173 (sub nom. T. faventia, Hew.) ; leucophmis (Hiibn.), pi. 39. 
fig. 126 ; T. dindymus (Cram.), pi. 39. fig. 126 ; T. spJmix (Hiibn.), pi. 39. 
fig. 124 ; T, syncellus (Cram.), pi. 46. figs. 207, 208 ; and T. punctum (H.- 
Sch.), pi. 40. figs. 132, 133. 
Stainton (Brit. Butt. & Moths, pi. 2) figures Theda hetultXy fig. 2, CJmj- 
sojdianus phlceasy fig. 3, and Polyommatus adonis, fig. 4. 
G, Allard records his capture of 9 species of this group in Algeria (Ann. 
Soc. Ent. Fr. 4® stir. vii. pp. 313, 314), and notices particularly Lycema psit- 
tacus (which he regards as distinct from L. halkanica, and believes to feed 
on Zizyphus mdgaris), L. adonis, L. martinii, L. melanops, and Theda lynceus. 
Lyccena argus (Linn.). Milliere describes and figures a variety of the 2 ®f 
this species. (Ann. Soc. Linn. Lyon, xiv. p. 319, pi. 73. figs. 4-6.) 
Theda ruhi. A variety noticed by Piffard. Ent. M. Mag. iv. p. 36. 
Lyccena alsus. E. Gedge notices the habits of this species. Its larva 
feeds in the flower-heads of Anihyllis vulneraria. Ent. M. Mag. iii. p. 206. 
Lyccena pseudargiolus (Boisd. & Lee.) is described in detail by W. II. Ed- 
wards, Proc. Ent. Soc. Phil. vi. p. 204. 
Lyccena medon (Hufn.) = Polyommatus agestis (Ochs.). Zeller (Ent. M. 
Mag. iv. pp. 73-77) describes the natural history and development of this 
species at some length. 
Lyccena hcetica. Life-history described by Newman, Entomologist, iii. 
p. 220. 
Guenee describes some peculiar organs possessed by the larva of Lyccena 
hcetica (Ann. Soc. -Ent. Fr. 4® s<lr. vii. pp. 666-668). On each side of the 
eleventh segment, close to the ninth spiracle there is a small aperture from 
which the larva, when disquieted, can protrude a short slightly pyriform 
organ, furnished at the extremity with a number of fine fleshy filaments like 
setse, which when fully extended, radiate from the summit of the organ. On 
the back of the tenth segment there is a single transverse aperture ; and from 
this a transparent hemispherical vesicle can be protruded. From this vesicle 
a fluid is exuded in considerable quantity. The author compares these or- 
gans with the fork protruded by the larvas of Papilio, but does not attempt 
any explanation of their functions. They are figured I, c, pi. 13. figs. 9-12.
