Perithecium pale straw-colored, becoming tinged with brown, tlic lower portiuu slighll/ 
inflared and abruptly contracted at the base, the distal portion snb-e(inio,il, si.inetinics sllglifly 
bent to one side, the apex narrow, truncate, symmetrical, the surface marked hy two .'-nries of 
ridges extending around the ])crithecinm, each series composed of four disfliiet and iiromincnt 
ridges placed somewhat irregularly and indicating the linos of separation between <lio middle 
and the upper and lower series of cells which form the walls of (ho main body of the jicrithc- 
cium; basal cells of the perithecium .^mall,f(.iir in munber, nn( dish'ngnished from it, but some- 
what abruptly distinguished from the distal stalk-cell, which is long, suli-cylindrieal, sometimes 
inflated and curved; the basal stalk-cell usuallv shorter and smaller, bcarin": distallv a sinirlo 
slender, simjile, rather closely septate, tapering appendage, usually about as lonjr ns Ihe distal 
stalk-cell. The ai)|)cndages, which together with the single stalked perithecium sjiring in groups 
of three or four from the di.stal ends of large cylindrical cells projecting from the suckcr-likc 
receptacle (more rarely arising from the latter directly), arc simple or once branched, either 
sterile or producing the solitary antheridia on short branches near their extremities. »^'i)orcs 
very minute, acicular, septate near the middle, 12 xS/i. Asci sub-cylindrical, 40-45 X 7.5/*, 
eight-spored, the spores sub-distichous, rerithecia, 225-290 x 55-75 /i, the stalk-cells (longest), 
425 p., average, 375-25 /i. Appendages, 175-375 /x long. Breadth of sucker-like receptacle,

This form, which is among the most remarkable in the whole group, inhabits only the softer 
Glutinous membranes of its host, beneath the elytra and at the bases of the legs or between the 
segments, which it perforates by the intrusion of its sucker-like base. From its lar^re size it is 
e 
readily seen, and when growing from the base of its host's legs projects upward, sometimes on 
both sides of the thorax, so that the whole or part of the perithecium rises free into tlic air. It 
api)ears to be decidedly rare, yet it will doubtless be found sufficiently abundant in localities 
where its host is more common than it has been found to be bv the writer. It varies consider- 
ably as to the number of perithccia which it produces as well as the size and number of cells in 
its intruded base.

Receptacle attached by a single basal cell, abov€ whicli it is parenchymatously multicellular, 
expanding distally ; its extremity cup-shaped with a distinct rim, from the inner surface of whi('h 
arise numerous sterile appendages, surrounding numerous stalked ap|)endiculatc perifliecia and 
antheridial branches originating from the central parenchyma- Antlierozoids exogenous, rod- 
like, terminal or short fertile appendages- Spores once-septate near their base. 
The present genus is without doubt the most reraarkalde of the many remarkable members 
of the family, and presents a degree of vegetative development scarcely to have been looked for
