PSYCHE. 



[February 1892. 



1SS8). Two weeks or more afterwards 

 (April 30) , I obtained six more chrysa- 

 lids at the same place, and one of the 

 flies which had come out in the hands 

 of the natives and is not perfect. One 

 of the lot secured upon April 30th came 

 out during the night of May 12th and 

 damaged itself slightly before I discov- 

 ered it. I send it in the envelope 

 marked 43, and the empty pupa-case in 

 a box marked with the same number. 

 Is not this an anomaly ? I have never 

 before obtained a moth from a chrysalis 

 hanging suspended as this one was. 

 When I got the chrysalis first I thought 

 now I have the chrysalis of Papilio an- 

 timachus or zalmoxis, and I'll get the 

 female sure. I had been led to suppose 

 from my reading that chrysalids so sus- 

 pended and comparatively unprotected 

 always produce diurnal butterflies. The 

 chrysalis is dark green in color, begin- 

 ning to change before disclosing the 

 moth to a pale green, and later to the 

 yellow of the empty shell." 



Mr. Good sent me of this brood six 

 perfect specimens, male and female, 

 and several chrysalids which had failed 

 to disclose the imago, and from one of 

 which the figure on Plate 5 is drawn. 

 Later he sent me three of the second 

 brood, and a chrysalid, which in form 

 is identical with the chrysalids of the 

 first brood, but smaller. This last 

 sending was accompanied by the fol- 

 lowing note : — 



"No. 43. — I designate these speci- 

 mens by the same mark, No. 43, as 

 those which I sent you in the summer. 

 The chrysalid appears to be identical in 



form and color, but the moths are very 

 different in color. If this is the same 

 species then the larvae bred in the dry 

 season do not produce as fine moths as 

 those that feed in the latter part of the 

 rainy season. These specimens emerged 

 Oct. 15th, iSSS, the rainy season, 

 which is late this year, having just 

 commenced." 



Rainy season brood. $ . Not dif- 

 fering materially from the figm-e and 

 description of Prof. Westwood. The 

 ground color is a bright yellow, with 

 the darker markings ochraceous rufous. 

 Expanse 6 1-2 inches. 



9 . Wings very broad, and not nearly 

 as pointed at apex as in the male. Gen- 

 eral color tawny ochraceous, with 

 darker markings deep burnt sienna. 

 Expanse of wings 7 — 7 1-4 inches. 



Dry season brood. The general 

 color of the two sexes is the same, and 

 may be described as Mars brown, with 

 the darker markings of a livid purplish 

 cast. Expanse of wings : $ , 4 3-4 

 inches; 9 5 — 5 1-2 inches. 



Idiomorphus vala Ploetz. 



Under this name Dr. Ploetz described 

 from a single female a species of Idio- 

 morphus (genus of Satyridae,) which 

 had been collected by Dr. Buchholz 

 upon the West African coast. The 

 species is very common upon the Ogove 

 River, at all events I have received 

 from Mr. Good many scores of exam- 

 ples, male and female. The larval 

 stages of this genus, which is peculiar to 

 the hottest parts of tropical Africa, have
