I have not included here Crabro albilabris , Panzeri , or brevis , of 
Shuckard and Smith, as the two former belong to the genus Lindenius , 
and the last to Entomognafhus ; they may all be known from the other 
black-bodied species by having their ocelli arranged in an isosceles 
triangle, much widest at the base.

ON TWO SMALL CONSIGNMENTS OF LEPI DOPTERA FROM THE 
HAWAIIAN ISLANDS. 
BY ARTHUR O. BUTLER, F.L.S. 
The following species were received some time since from the 
Rev. T. Blackburn, but press of work has hitherto prevented me from 
working them out. 
1. Danais arcitippus, Fabr. (No. 1.) 
This specimen somewhat resembles the southern American type 
in coloration. According to Messrs. Salvin, Godman, and others, it 
would appear that this is the species intended by Linnaeus in his 
original description of Papilio Plexippus , but as he gives China as one 
of his localities, it seems better to retain a name respecting which there 
can be no doubt. 
2. Protoparce Blackburnj, sp. n. (No. 30).

“ Occurs rarely near Honolulu.” — T. B. 
This handsome species, although nearly allied to the North 
American insect, is evidently quite distinct ; the wings are decidedly 
broader, the inner margin of the primaries longer and more curved, 
and the outer margin consequently less oblique ; in colour it is greyer, 
and the light markings are more or less white ; the arched double 
discal belt is represented by two coherent bands, the inner one con- 
sisting of confluent, black-edged, lunated, white spots ; the white 
spotting of the fringe is purer, and, consequently, more evident ; the 
sub-basal diffused black band of the secondaries is absent, and the sub- 
marginal band is broader, being of twice the width at costal margin ;
