it is not clear from Peyritsch's account ia what respects (liis f^pooii^s diffcis from L, jlag^'lhxta. 
The only peculiarity of the former species appears to 1)e that cell 111 is unusnally olongalod; 
yet this may have been accidental or due to f^ai'closs rojM'odtiction. That tho \\\nQ\\\ don gaf a 
occurs in Europe on Platynns (Anchomcnus) as "wcU as on Pristonyrhnn cavicola is an 
midoubted fact, the L. gigantea of Istvanffi being identical with the most typical forms of don- 
gata^ and the material which I have seen derived from species of riutynus taken in the neighbor- 
hood of Vienna, seems also not separable from the same form. The retention of tlie species as 
distinct from L, jlagellata and L. anceps is therefore provisional, and it may prove that all tljreo 
are the same.

position in which the plant grows ; this species illustratin.i^ better tlian any ofh^^r tlic variations 
w^hich have been previously alluded to (p, 240) as dependent on these circumstances. In brief, 
the species may be very eloni^atc (uiorc than a millimetre in Icn^rth from the foot to tlie apex of 
the perithccium) or very slii)rt (300 >t or even less) and stout ; in color it may vary from palo 
straw color to deep brown, specimens sometimes occurring that are nearly opaque ; the a]>jKjnd- 
ages may be short and stout or very long and slender, sometimes nlnjost simple, in other l. - s 
very densely branched, hyaline or opa(pie, yet conditions sliowing every gradatiim between tliese 
extremes arc so numerous as to rend<^r the separation even of varieties impossilde.

to the position of growth, since it occurs also on the jaws of the host as vrcll as when the para- 
site grows crowded at the tips of the elytra. The type-form is that which grows as a rule near 
the base of the legs on the inferior surface of the thorax, and is represented in fig. 4, Plate XV^L 
It is one of the commonest of all the species as well as the most widely distributed, and it is to 
be hoped that its great variability will not lead to an extended synononiy in the future.

pseudoparaphyses few in number (4-7), about equal, simple or divided at the base, colorless, for 
the most part exceeding the perithecium in length."
