cells, the apex made externally oblique through the outgrowth of oue 

 of the lip cells which forms a pointed projection beyond the pore ; the 

 stalk cell wholly free, tapering to a narrow base, and about as long as 

 the receptacle proper. Receptacle small, pointed below, its sub-basal 

 cell united throughout its length to the basal cell of the appendage, ita 

 basal and sub-basal cells separated by a horizontal septum. The ap- 

 pendage straight, rigid, tapering, composed of a series of usually four 

 superposed cells separated by oblique partitions, and bearing short 

 branches with flask-shaped antheridia from their upper inner angles. 

 Perithecia 200 X 45 /x. Length to tip of perithecia 350 fx. Length 

 to tip of appendage 200 /x. Length of receptacle 55 /a. 



On Pinophilus densus Lee. Utah. 



The occurrence of a second well marked species, abundantly dis- 

 tinct from the type, serves to settle any doubts which may have existed 

 concerning the validity of this genus. The present form was found 

 on the abdomen of its host, and is readily distinguished from S. La- 

 throhii by the peculiarly modified tip of its perithecium, as well as by 

 other important differences. 



Laboulbenia Hageni, nov. sp. 



More or less deeply tinged with brown. Perithecium slightly inflated, 

 tapering to the blunt outwardly oblique apex, which is blackened be- 

 low the hyaline lips. Appendages arising from an outer and an inner 

 basal cell, the outer of which is followed by a squarish cell of about 

 the same size, from the end of which project four rather short, rigid, 

 slightly divergent hyaline branches, which taper to blunt tips, and, as 

 a rule, hardly exceed the tip of the perithecium : the inner basal cell 

 gives rise to two squarish cells, one on either side, each of which 

 bears usually a pair of branches similar to those just described. Re- 

 ceptacle short and stout, normal in form, the lower portion of the basal 

 cell hyaline. Perithecia 55 x 18 /x. Appendages (longest) 65 fi. 

 Total length to tip of perithecium 100 jx. 



On Termes helUcosus var. Mozamhica Hagen. Africa. 



The occurrence of a most typical and decidedly insignificant looking 

 species of this genus on a larva of the worker of a species of white 

 ant is certainly quite unexpected in view of the wide difference which 

 exists between this Neuropterous host and the usual insects infested 

 by the genus. But for the four stiff branches arising from the sub- 

 basal cell of the outer appendage, and suggesting the roots of a molar 

 tooth, it would be difficult to specify its distinguishing characters. 

 The species is dedicated to the memory of the late Professor Hagen,
