the white border of which it is merged. The secondaries are like- 
wise ornamented by a triple row of ochraceous spots, of which the 
outer series consisting of five to six spots situated on the intraneu- 
ral spaces are the largest and obscurely hastate in form. The sec- 
ond series, consisting of five spots, has the one nearest the costa 
the largest. The third series is incomplete, and consists of one or 
two spots, of which the one nearest the costa is large and distinct. 
The underside is much as in D. Ogina , Hubn., save that the row 
of ocelli on the secondaries consists of five, instead of four, ocelli ; 
in this respect resembling D. Bcimbusce , Feld. Expanse of wings, 
$ 80 mm., 9 90 mm. Described from five males and one female 
in Coll. Holland. 
It is possible that the form received from Celebes and of which 
the above description has been given may be a local race of Ogina , 
and I was so inclined to decide, in spite of Mr. Doherty’s opinion 
that the species is new. A careful study of the figures of Hubner 
and Semper has caused me to reverse my first conclusion, and I 
have accordingly accepted Mr. Doherty’s view. In this connection 
the following extract from one of Mr. Doherty’s letters may be of 
interest to students of this group of insects : — “ There seem to be 
more species in the genus Discopliora than are usually recognized. 
The prehensores ought always to be examined in this genus. This 
Celebesian species has what I call the upper uncus bifid, while in 
Celinde it is entire. I regard this family (the Morphidse) as the 
original one from which all the four-footed butterflies are derived — 
speaking in entire ignorance of the South American Brassolidce. 
Except Xanthotcenia they have hairy larvae, they are all crepuscu- 
lar except the true Morphos, and queer primitive looking creatures, 
resembling other butterflies very much as the huge, clumsy Tertiary 
mammals their present descendants. Except Clerome and Xan- 
thotcenia (the two highest of the group) they have the curious habit 
of flying up and down a given space for an hour about sunset and 
sunrise, as if taking a u constitutional,” never varying a hair’s 
breadth from their given “ beat,” except when disturbed by another 
of the same species. In that case they fly with lightning rapidity 
and in a most erratic way, and once I saw a Discopliora dash himself 
to pieces upon an obstructive bough which he was apparently trying 
to fly through. This is quite true, though it sounds improbable. 
All the specimens I send you were caught in the twilight, though as 
I frequently remarked to myself, it seemed a shame to disturb them
