332 THAXTER. — MONOGRAPH OF THE LABOULBENIACEiE. 
Pkeropsophus from Spain is immature but appears certainly to belong here. I hope to illustrate this 
species more rally in a future paper. 
The varieties of this species which it has been thought desirable to distinguish by special names are 
as follows: 
var. Liberia ua Thaxter. Cell V constantly once-proliferous, the accessory appendage simple, dis- 
tinguished by a broad opaque black base. Type on Euderrm sp., Liberia (Cooke); British Museum No. 
591 on /.'. arcuatocoUe Murr., Old Calabar: Paris Museum Nos. 84 and 152 on Eudnna sp., Congo, Africa, 
in the original figure of this variety (Monograph, Plate III, fig. 7) the septum separating cell III from 
roll IV, was not inked in before reproduction, so that the figure is incorrect to this extent. The septum 
is almost exactly horizontal, and the two cells which it separates are about equal in length. The additional 
materia] obtained since this variety was described resembles the type in all respects. 
var. cixcTA Thaxter. Plate LIII, fig. 5. 
Proc. Am. Acad. Arts and Sci., Vol. XXXVIII, p. 53. June, 1902. 
Perithelium borne on a black base resembling a normal insertion-cell; cell V several times proliferous, 
each cell bearing a simple accessory appendage distinguished by a broad black basal suffusion. On 
Endrma simudicolle Laf., Lagos, Guinea; British Museum, No. 590. On E. grosmm Hope, Old Calabar, 
Africa; British Museum, No. 587. On Episcosvmus (Eudcma) grossus Hope, Africa; Paris Museum, 
No. 81. On Cnupedophorus adaqmtus Kolbe, Bismarkdorf, Togo, Africa; Berlin Museum, No. 919, 
and Kamerun, Africa; Berlin Museum, No. 912. On C. Conc/oanus Kolbe, Kimpoko, Congo, Africa; 
Berlin Museum, No. 907. On C. Prm.ni Kolbe; Barumba Station, Kamerun, Africa; Berlin Museum, 
Xo. 911). On C. (Eudema) Strachani Hope, Togo, Africa; Berlin Museum, No. 913. 
This variety is entirely similar to the var. IAberiana except that cell V is more than once proliferous, 
and that the perithecium is seated on a clearly defined black base which is like the normal insertion-cell 
of this genus. In the latter respect the variety is quite unique, since no other member of the genus shows 
any such tendency. The black portion appears to result from the modification of two cells (cells g and 
d, Monograph, Plate II, fig. 17). 
var. atrata Thaxter. Plate LIII, fig. 2. 
Proc. Am. Acad. Arts and Sci., Vol. XXXVIII, p. 53. June, 1902. 
Cell V twice to five times proliferous, the accessory appendages distinguished by thick black bases 
and either divaricately once- or twice-branched, or simple. Very variable in size, the type on Rhopalmnr- 
lus (Berlin No. 921) over 1.5 mm. in length, while specimens on Rkopalomelus from Port Natal (British 
Museum, No. 630) are only 450 \i to tip of perithecium. A fine variety, which, in the absence of inter- 
mediate forms, would never be specifieially associated with the normal form of proliferans. Specimens 
in which the accessory branches are simple (Berlin 909 and 908, Brit. Mus. G30) resemble var. cinrta 
exactly, except that no blackened base is distinguished below the perithecium. On Chhvn'uis Dohrini 
Bert., Tropical E. Africa; Berlin Museum, No. 220. On EuehUmitu trochanterics Kolbe, Njam Njam, 
Senmio, Africa; Berlin Museum, No. 921. On Cnupedophorus nvcahu Harold, "Uegne Lugna"?

atrata from the fact that one or all of its accessory appendages may be distinguished at the base by black- 
ened septa, although specimens occur in which no such blackening is present. It resembles the Asiatic 
forms of the species on the same host in general form, and in the Type (British Museum No. 599 on 
Lhlanuts sp., Angola), has the samp nnl*> «t™«r „ fl lL„, ™i„.: ^ • . • i #__ .i • :^«
