Laboul'benia proliferans Thaxtcr var. liberiana nov. var. Plate III, fig. 7. 



Like the type, but somewhat larger, the basal cell of the outer appendage always bearing a 

 slender external branch blackened at its base. Differing from the type from the fact that the 

 inner accessory appendage, which is usually solitary, is borne on an independent black insertion- 

 cell free above the normal one. 



On Eudema sp. indet., Liberia, Africa. 



This variety, although its peculiarity just described is constant in the considerable number 

 of specimens which have been examined from different individuals of its host, should not, I 

 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 collected by 

 Professor Cook, none of which bore specimens of the normal'form. 



Laboulbenia brachiata Thaxter. Plate XXI, figs. 5-7. 



Proc. Am. Acad. Arts aud Sci. Vol. XXIV, p. 11 j Saccardo Sylloge, Vol. IX, p. 1132. 



Hyaline or yellowish, becoming more or less deeply suffused with smoky brown. Perithecium 

 somewhat inflated, becoming smoky brown, deeper below the hyaline tips of the lip-cells. 

 Appendages nearly hyaline or in part suffused with smoky brown, arising from numerous small 

 unmodified insertion-cells, corresponding in number, except the outmost, to secondary divisions 

 of cell V, forming an obliquely superposed series from which the appendages arise in a double 

 row, the inner highest and usually somewhat smaller than those 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 series of five to seven cells, decreas- 

 ing in size from below upward, each opposite an insertion-cell ; the lowest insertion-cell 

 opposite a small roundish cell just above the extremity of cell IV. Spores, 60 x 5 \i. Peri- 

 thecia, 120-150 x 50-60 /x. Appendages, longer, 700-750 p. Total length to tip of perithecium, 

 400-590 fi. 



On Patrobus longicornis Say, Maine to Virginia ; on P. tenuis Lee, Hudson's Bay. 



This fine and apparently rare species was first taken in the vicinity of New Haven, and later 

 at York, Maine ; but has never been obtained in any quantity. A single specimen of its host 

 taken in Virginia by Mr. Pergande as well as several kindly sent me by Dr. Townsend, 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. fasciculata Peyr., although an approach to this condition is seen in L. proliferans. The anthe- 

 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
