Like tlic type, but soniewliat larger, llje ba.sal coll of the outer appendnge always bearing a 
Blender external branch blackened at its base, DliTcring from the tyj)e from fhc fact that the 
inner accessory ajipendagc, \rhicli is usually solitary, is borne on an independent black insertion- 
cell free above the normal one. 
On Eudema sp. indet.j Liberia, Africa. 
This variety, although its peculiarity just described is constant in the considerable number 
of specimens ^liich have been examined from different individuals of its host, should not, 1 
think, be separated as a distinct species on so comparatively unimportant a character. Like 
the other species from this locality, the present variety was obtained from hosts coUertod by 
Professor Cook, none of which bore speciuicns of the normal form.

Hyaline or yellowish, becoming more or less dcejily f^nffused with smoky brown. Perilhecinm 
somewhat inflated, becoming smoky brown, deeper bvlow the hynlinc tijts of the lip-cells. 
Appendages nearly hj^alinc or in part sufTnsod with smoky brown, arising from numerous small 
unmodified insertion-cells, corresponding in number, except the outmost, to secondary divisions 
of cell Y, forming an obliquely superposed series from which the nj)pendagc8 arise in a double 
row, the inner highest and usually somewhat smaller than tliose lower and outer in the series. 
Each appendage consisting of a rather large somewhat inflated basal cell, variable in size, which 
bears usually two branches simple or once branched, the basal cells of each branch or branchlet 
slightly inflated, the septa oblique and more or less blackened, the ultimate branchlets long, slen- 
der, mostly hyaline, somewhat flexuous and attenuated- Receptacle normal, except for the 
secondary division of cell V, which results in a superposed scries of five to seven cells, dccreas- 
ing in size from below upward, eacli opposite an insertion-cell ; tlie lowest inseiiion-c(ll 
opposite a small roitndish cell just above the extremity of cell IT. 8pores, 60x5 /a. Peri*

On Fatrohus lonjicornis Say, Maine to Virginia; on P. tenins Lr-c., Hudson's Bay. 
This fine and apparently rare species was first taken in the vicinity of New Ilaven, and later 
at York, Maine ; but has never been obtained in any quantity. A single specimen of its host 
taken in Virginia by Mr. Pergandc as well as several kindly sent me by Pr, Townscnd, collected 
near Eastport, Me., have yielded additional material, while two specimens of P. tenuis from 
Hudson's Bay in the collection of the Museum of Comparative Zoology were also found to be 
parasitized. It is apparently subject to little variation, and is distinguished at a glance by the 
regular secondary division of cell V, which is found in no other species with the exception of 
L. faseiculata Peyr., although an approach to tliis condition is seen in L. proliferan^. The authc- 
ridia are proportionately very small, and are borne usually in pairs, terminally on short one- 
celled branchlets (fig. 6). Whether or not the present species should be kept distinct from L
