zontal insertion of the free appendage. Appendage compact, rounded, 

 subsymmetrical, amber-brown; the flat basal cell undivided, about 

 equalling the pair of cells above it, from which arise two antheridia, 

 and, externally, a small cell bearing laterally a spinose antheridium; 

 the necks of the antheridia lying side by side, erect and parallel, or 

 bent shghtly inward and in contact, except distally. Spores 40X6 /x. 

 Perithecia, including basal cells 235-310X45-58 /z, its rostrate termi- 

 nation 80 yu- Receptacle including foot 45-60X35/1. Appendage, 

 free part including antheridia, 45-50X20 /i. 



On the elytra, prothorax and other parts of Telcphanus sp., Temper- 

 ley and Llavallol, No. 1992. 



Synandromyces geniculatus nov. sp. 



Similar in general to the last. Perithecium relatively smaller, 

 the main body tinged with deeper smoky brown, and lying horizontally 

 at right angles to the axis of the receptacle; asymmetrical, the distal 

 portion short, rostrate, tapering more or less to the short hyaline 

 tip; which is often abruptly somewhat narrower, sometimes slightly 

 inflated, irregularly papillate; the base inserted laterally on the 

 short, abruptly bent, constricted stalk-cell. Receptacle as in the 

 previous species, but relatively longer, strongly curved below. The 

 free portion of the appendage relatively smaller, tinged with smoky 

 brown. Spores 30X5 /j.. Perithecia 135-155X45-60 n, rostrate 

 termination 45-50 fi. Appendage including antheridia, free portion, 



SOX 20 m. 



On the superior surface of the tip of the abdomen and less frequently 

 on the adjacent tips of the elytra, often with the last, on the same host, 

 Telephanus sp. Temperley and Llavallol; Nos. 1508, 1992. 



This species grows, usually somewhat crowded, in the position 

 indicated, and I have not seen it on the elytra except at the very tips, 

 where S. Telephani may also occur. It can thus hardly be regarded 

 as a variety due to its position of growth. It may be easily distin- 

 guished from S. Telephani, even with a hand lens, from its darker 

 color, smaller size, and sigmoid habit. 



Stigmatomyces Anoplischii nov. sp. 



Faintly yellowish olivaceous with conspicuous brown shades near 

 the base of the appendage on the inner side. Perithecium relatively 

 very large and long, the venter greatly elongated, but slightly inflated;
