by whom it was observed many years since on the same specimen ex- 

 amined by the writer, collected by Dr. Peters in Africa, from all parts 

 of which sufficiently abundant material was obtained. 



Laboulbenia Kunkelii (Giard).

Through the kindness of Professor Giard, the writer Las had an 

 opportunity of examining specimens of this remarkable species, which 

 is by far the largest member of the family, measuring between three 

 and four millimeters from its base to the tip of the peritheciura. It 

 occurs with the succeeding species on the elytra and thorax of Mormo- 

 lyce phyllodes Hagenb., a carabid beetle, native in the East Indies. 

 The writer is unable to agree with Professor Giard in believing that 

 this form, however singular, should be separated generically from 

 Laboulbenia, to which it seems to correspond in every essential de- 

 tail. The type of cell arrangement, so characteristic in Laboulbenia, 

 is followed without deviation ; while the appendages also originate 

 in a manner much more typical than is found in very many species 

 of this genus. The elongation of the basal wall cells of the perithe- 

 cium to form a stalk-like base finds also an exact parallel in species 

 like L. Galeritce, L. longicoUis, L. melanotheca, and other forms, the 

 generic reference of which is not to be disputed. 



Laboulbenia palmella, nov. sp. 



Perithecium nearly straight, almost opaque, sometimes slightly in- 

 flated, its tip nearly symmetrical, truncate, its inner walls often having 

 a corrugated appearance, the four lower wall cells elongated and con- 

 tracted to form a short stalk below and about one third as long as the 

 ascigerous portion. Appendages arising from two small basal cells : 

 an outer which gives rise to a series of two or three opaque branches 

 placed antero-posteriorly, the inner of which alone reaches any con- 

 siderable size, branching sympodially in an antero-posterior plane, the 

 main axis opaque, successively inflated below the branchlets which 

 are usually about ten in number, opaque with hyaline tips: an inner 

 which gives rise to a single branch on either side consisting of a sub- 

 cylindrical basal cell, black below, nearly hyaline above and followed 

 by a series of sympodial branchlets like those of the outer appen- 

 dage. Receptacle short, tapering rapidly to the base, wholly black 

 and opaque with the exception of the whole or a portion of its basal
