200 THE ENTOMOLOGIST. 
var. of P. Tipha, L., but its facies is so different as to make 
it quite as worthy of specific designation as many that are so 
honoured now-a-days. The outline of the wings is quite different ; 
—much broader behind, the hind pair much squarer. The 
beautiful pearly white area of the upper surface (whence I have 
chosen its sp. name) occupies fully half of the whole, and has 
between it and the margin (in the f. w.) two white spots, of which 
the anterior is the more conspicuous and well-defined; in some 
specimens, however, there is only a dim trace of this spot, and 
none of the second. Beneath, there is little difference that is 
describable. Exp. 2 to 2°5 inches. It seems in some respects 
intermediate between Tipha and Neerea, L. Paraguay; at edges 
of woods; rather plentiful. Sept. to Mar. (See fig. 6). 
Eubagis Artemisia, Fabr. Moderately common near Asuncion, 
about puddles. Dec. to Mar. 
Catagramma Sorana, Godt. From Asuncion northward : 
about puddles. Scarce. This appears to be C. Zerynthia of 
Burmeister (Rep. Arg. Lepid., 173, 511, Atl. v. fig. 9), but not the 
C. Latona of Butler (Lep. Exot. 181, pl. 63, fig. 3). All are grand 
species ! 
C. Pyracmon, Godt. Throughout Paraguay. Oct. to March. 
Plentiful in some parts: frequenting puddles in the open. 
C. Hydaspes, Dru., has not yet been sent me; but it is said 
to reach to Corrientes. 
Hematera Thysbe, D. & H. Near Asuncionin Dec. About 
puddles: searce. 
Didonis Biblis, Fabry. A few examples taken in April, in a 
forest-path on the bank of the River Corrientes. In Paraguay it 
is found throughout; from Sept. to March; always in or near 
woods, in no great plenty. 
Megalura Peleus, Sulz. Near Asuncion, in the open, in Dec. ; 
very rare. 
M. Chiron, Fabr. Near Asuncion, and farther north. Affects 
the vicinity of water: not common. 
Heterochroa Iphicla, Linn. Near Asuncion; moderately com- 
mon, at the edges of woods: Nov. to Feb. 
Apatura Agathina, Cr. Sent from Corrientes, and, somewhat 
more numerously, from Paraguay. In both regions, it 1s 
accredited with a proclivity for stagnant puddles and wet mud, 
like its imperial relative here in England.
