et les deux autres sur le milieu, vers le bord exterieur. En-dessous le 

 corps est d'un rouge brun clair. Sur I'abdoiuea quatre points blancs. 

 Les ailes inferieures vers le corps sont blanches ; le reste avec les ailes 

 superieures sont bandes transversales dentelees brunatres. La trompe 

 est longue." 



Perigonia restituta. 



To the kindness of Mr. J. W. Weidemeyer we are indebted for in- 

 formation about this MSS. species, of which Mr. S. Calverley has 

 shown us a figure made under the superintendence of Mr. Walker. 

 It is an elongate species with rather narrow wings, and belongs to the 

 typical group of the genus which contains F. htsca, P. stulta, and P. 

 le/ebn-ii. The posterior wings are much produced at anal angle, which 

 is shaded with yellow scales. The median yellow demi-band, which is 

 characteristic of the genus, extends from the costa, where it is broadest, 

 to about the centre of the wing, where it terminates with a rounded 

 inward inflection. It is from Mexico. P. suhhamata and P. glauces- 

 cens, present structural differences compared with the species cited 

 above, and which are more typical of the genus; the figures which we 

 have seen of these latter two of IMr. Walker's species, suggest that these 

 might be separated generically from Perigonia. 



Proserpinus gaurae. 



It is very probable that the species described by Dr. Clemens under 

 this name from Texas, is not the same as the one intended by Abbot 

 & Smith, since the Texan species is stated by Dr. Clemens to disagree 

 with Abbot's figure in the conformation of the external margin of an- 

 terior wings, and. from the description, it would seem to differ also 

 slightly in coloration. 



ETJIEOSERPINUS, nov. gen. 



Wings entire: anterior pair large, rounded superiorly along external 

 margin, much excavated before the exserted internal angle; internal 

 margin straight. Secondaries reduced, subtriangulate, hardly excavate 

 beiore anal angle; external margin slightly rounded. Antennae, stout, 

 flexuous and long. Head, rather small; prothoracic parts but slightly 

 advanced before the insertion of the primaries. x\bdomen, slender, well 

 exceeding the secondaries, furnished with regular series of long hair- 

 tutts on the terminal segments above, and laterally the anal segment 

 with a spreading terminal tuft. 



We erect this genus for a small California species of the present 

 Family, which, while allied to Proxerpinm^ differs by the small, reduced 

 secondaries, longer antennae and tufted abdomen. We are indebted to
