336 THAXTER. — MONOGRAPH OF THE LABOULBENIACE^. 
The individual represented in fig. 13 was found on 8. genicidatus Ehr., from England, and was at first 
given a specific name corresponding to the host; but although an examination of abundant material may 
show i iential and constant differences, I have preferred to place this form also provisionally under the 
present species. 
Of the forms on Anophthalmia the following have been examined: British Museum No. 660 on

(Edodactyli Thaxter. Plate LIV, fig. 10. 
Arts and Sci., Vol. XXXV, p. 189. Dec, 1899. 
Perithecium free except at the base, pale transparent amber-yellow, somewhat inflated at the base 
and tapering gradually thence to the slender tip, a blackish shade below the nearly hyaline lips which are 
turned slightly outward. Receptacle amber-colored, deeper anteriorly, cell 11 sometimes elongate, cell 
VI very short, so that the base of the perithecium comes opposite cell III. Insertion-cell and the inner 
margin of cell V usually free from the perithecium. The outer appendage simple, divergent, the basal 
cell very large: the basal cell of the inner appendage much smaller, bearing one to two short branehlets. 
Spores 35-40 X 41 ft. Perithecia 120 X 35 ft. Total length to tip of perithecium 175-380 a (longest); 
to insertion-cell 115-275 ,«.

The material of this .species is unfortunately very scanty, the typical form being represented in fig. 
10, and recalling L. Atlantica, although its color, the conformation of the perithecium and of the recepta- 
cle, as well as its slender tapering colorless outer appendage, serve to distinguish it. 
Laboulbenia Atlantica nov. sp. Plate LIII, figs. 16-17. 
Perithecium dark olivaceous brown, short, stout, about two thirds free from the receptacle; the free 
portion subsymmetrieal, or curved outward; the tip hardly distinguished, bent slightly outward, with 
darker subterminal suffusions. Receptacle short and rather stout; cells I and II subequal pale dirty yel- 
lowish, the distal half, or less, of the latter united laterally to cell VI; cells III and IV subequal, short 
and broad, and eoncolorous with the perithecium. Outer appendage yellowish, simple, elongate, diver- 
gent, tapering but slightly, rather closely septate, lower cells slightly constricted at the septa; basal cell 
of the inner appendage bearing a short one-celled branch on either side, from which arise a few antheridia. 
Perithecium 90 X 70 p. Receptacle 110 pu Greatest total width 58 //. Longest appendage 380 ft.

Gargut Schaumii WolL, Ambentes, Madeira, Paris Museum No. 212. 
Although the hosts of these two forms belong to different families of Coleoptera, I am unable to sepa- 
rate them specifically, the specimens on Gargm differing only in the slightly greater relative length of the 
basal and subbasal cells and in a slight tendency to general curvature in the free portion of the perithe- 
cium. I he material on Lathrobium is taken as the type, one of the individuals from this source being 
represented in fig. 16, while figure 17 represents an individual from Gargus. The species is allied to L. 
subtcrranea and L. (Edodactyli, but seems sufficiently distinct from pitW
