No specimens of either j/tsfir/nc or mcroptt liave been recorded from the 

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

 to hand it is not jtossible 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 geminus and lugens, separatus 

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

 justiciae and merops, though the argument is by no means conclusive.

The tyjies of ^/^f;;« and (in<h-omi'(l<te arc the same in the se.xnal armature as 

 well as in size and jiattern. Boisduval's description of amlroinrilae of 187.5 refers 

 to two species ; his htgcns of 187;") is not AValker's lugens, but Boisduval's morops 

 of 1870. (ilemens's sordida var. B. is either higcns 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 sejiarate species, namely, 

 seijaratKS and cremitoides, as synonyms of Ixgcus. The synonymy as given by 

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



c? ? . In appearance like an enlarged edition of eremilus; 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 in S , a little shorter in cJ. 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. 



S . Tenth .ibdominal tergito (PI. XXV 111. 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. Harpe 

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

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

 hook ; tlie subdiirsal 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 jjlate (PI. XX. f. 12) longer than in the other sj)ecies of Hyloicus 

 with non-spiuose midtibiae, the distal part membranaceous, mesially folded trans-
