138 CATALOGUE OP DIURNAL LEPIDOPTERA. 



Para", Lower Amazons. (Obtained 1849, collected by H. W. Bates, 



Esq.) B.M. 



In the e Genera of Diurnal Lepidoptera ' the P. Lamia of Cramer 

 (Pap. Exot. ii. pi. 150. fig. C) is regarded as synonymous with P. 

 Dardus; the latter, however, differs from P. Lamia in having no 

 brilliant blue reflection upon the posterior wings. 



3. Enrybia ? Constantins. 



Papilio (N.) Constantius, Fabricius, " alis integerrimis, obscure 

 cinereis, striga marginali punctorum fuscorum : habitat . . . ." 

 Fabricius, Ent. Syst. iii. p. 152. n. 468 (1793). 



Not in the British Museum. 



This species seems to come near to the species of Eurybia, but 

 wants the conspicuous central ocellus of the anterior wings ; it is 

 figured in the unpublished ' Icones ' of the late Mr. Jones. 



Genus 5. MESOSEMIA, Hubner, 

 Verz. bek. Schmett. p. 20 (1816). 



1. Mesosemia Menippus. 



Papilio (P. U.) Menippus, Fabricius, " alis integerrimis, striatis, 

 fuscis, fascia lata alba : habitat Surinami." 



Fabricius, Gen. Ins. p. 272. n. 397, 398 (1776) ; Sp. Ins. p. 138. 

 n. 640 (1781) ; Mant. Ins. p. 91. n. 827 (1787) ; Ent. Syst. 

 iii. p. 353. n. 341 (1793). 



This species is, in the ' Genera of Diurnal Lepidoptera,' referred 

 to the genus Pyrgus (Hesperidce) ; it seems, however, to be nothing 

 more than a faded Mesosemia, probably M . Sifia, Boisd. ; although 

 we have the latter species only from Bogota, it is registered in the 

 ' Genera' as coming from Brazil. 



2. Mesosemia Ulrica. 



3 . Papilio (P. R.) Ulricus(sw), Fabricius [P. Ulrica, Cramer], " alis 



integris, cseruleo nitidis, subtus basi brunneis ; anticis ocello tripu- 



pillato : habitat Surinami." Pap. Exot. ii. pi. 100. figs. E, F (1779). 



Fabricius, Sp. Ins. p. 127. n. 572 (1781); Mant. Ins. p. 82. 



n. 735 (1787); Ent. Syst. iii. p. 314. n. 187 (1793). 



Ega, Upper Amazons. (Obtained 1857, collected by H. W. Bates, 



Esq.) B.M. 



The M. Machcera of Hewitson may be the female of P. Ulrica ; 

 the under surface of the two insects and their general form are very 

 similar ; moreover we obtained both in the same collection. 



3. Mesosemia Philocles. 



Papilio (D. F.) Philocles, Linnceus, " alis integerrimis, fuscis ;
