straight; the character of the outer appendage, which is more or less deeply suffused toward the base and 
from the basal or subbasal cells of which, sometimes from both, arise simple, more or less rigid branches 
of variable length, lapsing and rather slender; the normal color of the receptacle and perithecium is a 
characteristic red amber-brown, which may often be obscured by smoky brown shades. Some South 
African and Madagascar specimens are uniformly pale yellowish, sometimes without any suffusions, even 
in the appendages, and closely resemble the simple types of L. Brachini which replaces L. Rougetii on 
tin ■ hosts in the western hemisphere. 
Two varieties on Brachini from the Orient are distinguished below. Exclusive of these, the material 
examined of this species is as follows: Paris Museum No. 30 on Brachinus sp., Algeria; No. 35 on Chlai- 
niu» teneocephahu Dej., Algeria; No. 61 on Brachinus nigrkornis Gebl., Asia; No. 62 on Brachinus 
sp., Africa; No. 129 on Brachinus sp., Turkestan; No. 196 on Chlamius gracilicollis, Turkestan (also 
from British Museum Xo. 596). British Museum No. 532 on Aptinus sp., Port Natal, Africa; No. 538

The following varieties occurring on the larger oriental species of Brachini may be distinguished. 
Var. Chinensis nov. var. This form which is common on various oriental species of Brachinus, 
is distinguished by its large size, 450 p to the tip of its perithecium, and the luxuriant development of its 
several times divaricately branched appendages which may measure more than 450 p. The general color 
and form of the receptacle are as in the type, the perithecium more distinctly inflated as shown in fig. 8, 
Plate LV, which is much reduced.

Museum Xo. 539, China. 
Var. Japanensis nov. var. This is a large form, the largest specimens measuring 700 u to the tip of 
the peritheciuin, and is distinguished by the very stout outwardly curved relatively short appendages, 
which are closely branched at and near the base; the whole basal region becoming black and opaque in 
some specimens, a condition not marked in the individual illustrated in Plate LV, fig. 7. The general 
color is as in the type, the perithecium somewhat inflated and relatively small. The twenty-five specimens 
of various ages that have been examined are constant and readily separable from any other forms of L. 
Rougetii. In a few individuals the dense branching of the appendages gives an appearance very similar 
to that seen in certain forms of L. Brachini. The branches do not, however, result from a repeated pro- 
liferation of the basal cells, the characteristic oblique black septa are absent, and the antheridia are of a 
different ty|>e.

The species is thus similar on the one hand to L. flagellata and its near relatives, and on the other 
to L. Brachini through the var. Japancnslf.
