200 MOXOGRAPn OF THE LABOULBEXIACE^. 
* 
his classic " Illstoire Natiirelle des Yegetaux Parasites," in wlilclij for the first time, 
the vegetable nature of these organisms was recognized. ■ In this work two species are 
enumerated, for the reception of which the new genus Lahoulbenia Montague et C. Robin 
■ 
(e familia Pjrenomjcetum novum genus) was erected ; the generic name being selected 
in honor of the entouiologist Laboulbene, who was, perhaps, the first to observe the 
L. Hourjdil of these authors, Avhich occurs on species of Brachimis in Europe. The 
second form, L. Gucrinii, was obtained from a South American species of the aquatic 
genus Gf/rctes, and both are figured and described at considerable length. Although 
the spores are described, no mention is made of their origin ; while the perithecia are 
spoken of as sporangia. It is, therefore, somewhat uncertain what this author's views 
really were in regard to the position and relation of the forms described, although 
the comment " Genus sphooriaceum, maxime singulare, entomogenum, quoad perithe- 
ciuin Capnodio analogum" would lead one to suppose that it was thou^-ht to be 
ascigerous.

L. Ilwjcm. In 18o7 also, Kolenati, in a paper entitled " Epizoa der Njcteribien," 
described certain parasites on these wingless flies, which infest various snecies of 
bats, placing them an.ong the worms in a new genus to which he
