No specimens of either juHticiac or vierops liave been recorded from tlie 

 Amazon basin, Surinam and Venezuela. Until material from these regions comes 

 to hand it is not ])ossible to say with certainty whether the two insects are mere 

 representative forms of one species, or are specifically distinct. It is worthy of note 

 that they differ in the harpes in a similar way as yemimis and litf/ens, separatus 

 and eremitoulcs. This is an argument in favour of the specific distinctness of 

 JKSticiiw and mcrops, tliough the argument is by no means conclusive.

The types of itf^g«,9 and andromedae are the same in the sexual armature as 

 well as iu size and ])attern. Boisduval's description of andromedae of 1875 refers 

 to two species ; his lugens of ISTTi is not Walker's lugens, but Boisduval's merops 

 of 1870. Clemens's sordida var. B. is either lugens or geminus ; his var. A. is 

 the insect which was formerly identified, erroneously, as leucophaeata, and more 

 recently, also by mistake, as andromedae. The synonymy becomes still more 

 involved by the American entomologists sinking two separate species, namely, 

 separatus and eremitoides, as synonyms of lugens. The synonymy as given by 

 Smith, I.C., comprises five distinct species. 



c??. In appearance like an enlarged edition oi erem/tits; first protarsal segment 

 longer, with three or four prolonged spines, of which the apical one is more than 

 one-third the length of the segment. Forewing, above, blackish grey ; there is 

 mostly a longitudinal line in the apex of the cell ; the white dots of the fringe are 

 much .smaller than the black spaces between them. Hindtibia as long as the first 

 and second tarsal segments together iu ? , a little shorter in c?. Black spots of 

 underside of abdomen small, generally only one distinct. Black median band 

 of hindwing narrowing behind, often more or less longitudinally divided by grey 

 scaling. 



cJ. Tenth abdominal tergite (PI. XXVIII. f. 7) rather suddenly narrowed in 

 middle, then slightly narrowing to the end, which is rather obtuse, gently bent 

 downward, upperside convex, underside sulcate ; sternite with an obtusely trian- 

 gular, flat, mesial lobe, which is sinuate and slightly curved upwards. Har])e 

 (PI. XXXVI. f. 18. 19) non-denticnlate, deeply concave on the surface, ventral 

 margin rounded-dilated, distal margin produced at upper angle into a prominent 

 hook ; the subdorsal fold of the clasper with very long bristles. Penis-sheath 

 produced into a slightly curved half-cylinder, which is round at the tip and bears 

 before the end a small sharp tooth (PI. XXIX. f. 8). 



?. Vaginal jilate (PI. XX. f. 12) longer than in the other species of llyloiciis 

 with non-spinose midtibiae, the distal part membranaceous, raosially folded trans-
