X GO-70/x. Appendages, longest, 360 /a. Total length to tip of peri- 

 thecium, 275-350^. 



On the elytra and abdomen of Platyprosopus Beduinus Nordm. ; 

 Berlin Museum, No. 810 ; Nubia. 



Laboulbenia producta nov. sp. 



Perithecium faintly tinged with pale dirty brown, rather long and 

 slender, nearly erect, free except the rather narrow subhyaline base ; 

 the lips somewhat prominent, outwardly oblique, the inner subtended by 

 a dark suffusion. Receptacle tapering to a slender pointed base, the 

 basal cell hyaline, becoming faintly tinged with dirty brownish, contrast- 

 ing with the opaque subbasal cell which is less than twice as long; cells 

 III and VI subequal, nearly opaque, reddish brown ; cell IV nearly 

 opaque, continued upward to form a free blunt well-defined prominence 

 which projects beside and slightly beyond the basal cell of the append- 

 age ; cell V relatively very large, extending to the base of cell IV, wholly 

 pale dirty brown like the perithecium, contrasting. Insertion-cell rela- 

 tively large, slightly oblique inward, resting below on cell V and later- 

 ally and obliquely on cell IV. Basal cells of the appendages nearly 

 equal, subisodiametric, the outer bearing an outer and an inner simple 

 hyaline branch distally, the basal cells of which, especially the inner one, 

 are more or less inflated, roundish, with dark septa, and tinged with 

 dirty brown ; the basal cell of the inner appendage beariug a branch 

 on either side similar to those of the outer, the branches hardly ex- 

 tending to the tip of the perithecium. Spores 55 X 4jn. Perithecium 

 90-100 X 25 /a. Receptacle 110 /j to insertion-cell, the projection above 

 10-12 p. Total length to tip of perithecium 220 p. 



Growing appressed on the bristle-like hairs on the elytra of Anchono- 

 derus concinnus Dej., Columbia; Berlin Museum, No. 1023. 



Laboulbenia proliferans, Thaxter. 



This species, which is very widely distributed throughout the warmer 

 regions of the eastern hemisphere, presents very numerous variations in 

 form, size, color, degree of proliferation and character of appendages, 

 among which the following seem sufficiently constant to warrant a 

 varietal name : 



Var. Liberiana Thaxter. Cell V constantly once proliferous, the 

 accessory appendage simple, distinguished by a thick, jet black base.
