A few specimens suggesting a hybrid between this species and the 

 nearly allied L. Galerita:, which occurs in company with it, were 

 found on a specimen of G. mexicana from Nicaragua associated with 

 the normal form. In the variety the appendages and receptacle are 

 those of L. mexicana, while the perithecium with its slender neck- 

 like base, although not punctate, is that of L. Galeritce. 



Labodlbenia longicollis, nov. sp. 



Perithecia becoming suffused with dark brown, straight, thick- 

 walled, often slightly inflated, the apex short, rather large, abruptly 

 distinguished, black, its lips hyaline turned slightly inwards. Appen- 

 dages consisting of two basal cells, the inner smaller, bearing distally 

 two rounded cells, the upper surface of each blackened and bearing 

 two to five branches which arise side by side and spreading laterally 

 may be successively and similarly twice branched, the whole having a 

 fan-like habit, the ultimate branches usually one to three in number, 

 either bearing two to three long-necked antheridia, or sterile, some- 

 what elongate, straight and tapering. The outer basal cell superiorly 

 and externally blackened, the blackened ridge extending obliquely 

 outwards and downwards nearly to the base, bearing a row of closely 

 set branches of variable number (three to five) which are successively 

 three to five times dichotomously branched, the ultimate branches suf- 

 fused with brown, straight, slender, tapering ; the basal cells of all the 

 main branches hyaline, slightly inflated inwardly, the septa black, con- 

 trasting. Receptacle large, cell (5) as large or nearly as large as 

 cell (4), the basal cells of the perithecium about 175 jx in length. 

 Spores 75 X 6.5 ^. Perithecium 180-220 X 50-60 ^l. Longest 

 appendages 510 ^u,. Total length to tip of perithecium 500-780 /l*. 



On elytra of Galerita leptodera Chaud., Guinea. 



A very large species, allied to L, GaleritcB and L. mexicana, from 

 which it is distinguished by its complicated and highly developed 

 appendages, and the remarkable elongation of the base of the 

 perithecium. 



Laboulbenia texana, nov. sp. 



Perithecium wholly suffused with blackish brown, short, its upper 

 half free, the outer edge abruptly curved inwards to the base of the 

 very prominent apex, the lips of which are brown, slightly pointed. 

 Appendages two, hyaline, almost distinct above the very broad black 

 insertion cell, the outer broad at the base, tapering distally, strongly 

 curved inwards, rather closely septate, a small cell opposite each sep-
