THAXTER. — LABOULBENIACE^. 477 



On BemUdium cojnplanulum Mann. Wasliington (Miss Parker). 



The five types of this singular species are all in poor condition, the 

 appendages being, for the most part, broken; but it seems safe to 

 describe it without regard to the termination of its appendages, since 

 the terminal projection from the perithecium distinguishes it from all 

 other known members of the genus, and finds a parallel only in 

 L. Gyrinidarum, with which it can by no chance be confused. It 

 was found on two specimens of the host, in each case growing ia 

 a definite position towards the base of the right elytron. The 

 beetles were among material kindly collected for the writer by Miss 

 A. M. Parker. 



Laboulbenia Oberthuri Giard (in lit.). 



Nearly hyaline except the brown or smoke-colored perithecium and 

 sub-basal cell of the receptacle. Perithecium large, inflated towards 

 the base, the narrower distal half abruptly rounded and contracted 

 below a rather narrow apex vath protruding lips bent outwards; 

 general color dark brown, much deeper below the apex. Appendages 

 numerous, crowded, slender, short, the lower segments inflated, arising 

 as in L. Guerinii. Receptacle elongate, consisting of a short curved 

 stout nearly hyaline basal cell, a very long sub-cylindrical sub-basal 

 cell smoky brown in color with deeper brown wart-like or scale-like 

 scattered prominences of varying size, the remaining cells normal 

 except that the insertion cells of the appendages are irregularly 

 divided. Perithecium 300-315 X 120 /a. Receptacle 1 mm.-900 /x ; 

 its sub-basal cell 370-425 x G5-75 ^. Total length to tip of 

 receptacle 1.225 mm. 



On Orectogyrus heros, Reg. Madagascar. 



This fine species has been kindly communicated to the writer by 

 Professor Giard, who has dedicated it to M. Rene Oberthur, its discov- 

 erer. It is with the exception of the two species described above on 

 Mormolyce by far the largest of the Laboulbenife, and is closely allied 

 to the form already known on Gyretes (Z. Guerinii Rob.), from 

 •■which, however, it is abundantly distinct. 



Heimatomyces distortus, nov. sp. 



Pale yellowish, more or less clavate in general form. Perithecium 

 inflated, its external margin strongly curved, becoming abruptly con- 

 stricted below a long slender tubular terminal mouth, which is usually, 

 but not always, bent abruptly outwards almost at right angles to the 

 nearly straight inner margin of the perithecium. A short straight
