variations except in size. The additional material examined is as follows: Berlin Museum No. 972 on 

 Galerita femoralis Murr., Gaboon; No. 971, on G. attclaboides Fabr., Guinea. Paris Museum No. 10 

 on Galerita sp., East Africa. British Museum No. 522 on G. femoralis Murr., E. Africa; No. 524 on 

 G. AJricana Dej., Angola; No. 523 on G. interstitial^ Dej., Sierra Leone. Fig. 10 of the accompanying 

 Plate is drawn from material on an undetermined species of Galerita collected by Dr. O. F. Cooke in 

 Liberia.

Perithecium straight, its base free from and higher than the insertion of the appendages, straight to 

 strongly recurved, becoming suffused with pale brownish; the tip blackish brown in normal specimens, 

 well distinguished, with prominent lips (when curved, not abruptly distinguished, somewhat pointed, 

 with ill defined lips), the translucent edges dirty brown. Receptacle hyaline or concolorous with the 

 perithecium, sometimes becoming dark smoky brown ; cell V often as large as cell IV, pushing the small 

 subtriangular unmodified insertion-cell outward so that it may become lateral, with its transverse diameter 

 vertical, cell VII unusually large. Appendages consisting of an outer and an inner basal cell, the two 

 free from one another except at the base, mostly several times as long as broad and overlapping slightly; 

 the outer bearing an external row of superposed branches, usually seven or eight in number, formed by 

 the successive proliferation of the tip of the basal cell, and separated from it by broadly blackened septa; 

 the branches successively subdichotomously branched several to eight or more times, the basal and some- 

 times the subbasal cell often producing more than two branchlets (two to four) superposed in a single 

 row. The inner appendage like the outer, the basal cell producing a single similar row of branches fewer 

 (usually two to four) in number, overlapping those of the outer appendage and bearing antheridia in groups 

 of from one to eight not characteristically grouped, the venter rather abruptly distinguished from the 

 straight cylindrical purplish neck: the branches of both appendages directed outward, hyaline or distally 

 reddish or purplish, constricted at the lower purplish septa. Perithecia (largest) 230 X 55 a; average 

 170 X 40 u. Total length to tip of perithecium very variable, from 275 /£ to 1 mm. Appendages 200- 

 350 fi. Antheridia 16 X 4 u. Spores 65 X 6.5 ;i.

This fine species is a characteristic form, common on the larger species of Brachinus from the far 

 East. Although it has not been seen on the numerous Brachini examined from intermediate stations, 

 the form previously separated as L. Italica on B. explodens from Italy, does not appear to be more than a 

 variety. The species is decidedly variable in form, size and color, often abnormally bent, as in Fig. 5, 

 or greatly elongated; becoming suffused in many cases till the perithecium is nearly opaque. The verti- 

 cally elongated basal cell of its inner appendage lacks entirely the right and left development of branches 

 which normally occurs in the genus, and usually overlaps the similarly developed basal cell of the outer 

 appendage. A similar condition is seen in L. pusilla, L. Japonica and L. rhinophora, yet these three 

 forms seem otherwise so different that their separation as distinct species appears desirable.

Perithecium free except at its base, rather short and stout, the upper half or third curved strongly 

 outward, the tip large, suleate, blackened, the lips coarse, nearly equal, subhyaline. Receptacle con- 

 colorous with the perithecium, the base nearly hyaline, usually bent between cells I and II, short, abruptly 

 expanded above cell II, the anterior margin straight above cell I. Appendages compact, the basal cells 

 subtriangular, the outer producing externally an oblique row of about four superposed branches from a
