374 M. F. Meinert on Mochlonyx (Tipula) 
We have no doubt that our plant is what is mentioned by 
Fries, Hym. Eur. p. 575. It forms confluent patches many 
inches in length.

On decaying wood, Penzance, J. Ralfs. A very different 
species from S. tabacinum. 
2027. S. stratosum, B. & Br. Effusum, lete ochraceo- 
album glabrum lutescens hic illic rngosum, contextu pallido 
stratoso, stratis demum solutis. 
Penzance, J. Ralfs. 
At no. 1962 for “Marasmius” read “Hygrophorus.” We 
are glad of this opportunity of correcting an unfortunate error, 
as this is, in all probability, the last of a long series of notices. 
XLIV.—Mochlonyx (Tipula) culiciformis, De Geer. 
By F. MEINert™*. 
In the year 1776 De Geer, in his ‘ Mémoires pour servir a 
Vhistoire des Insectes’ (tome vi. p. 372), described the de- 
velopment of a small midge or gnat, T¢pula culictformis, and 
gave (on pl. xxiii. figs. 3-12) figures of the larva and pupa 
and of the male imago. De Geer had found the larva in the 
month of May in pools and swamps (“des étangs et des 
marais ”) and successfully bred them ; but since that time no 
one seems to have met with the larva, indeed the imago itself 
seems not to be known, and some doubt has arisen as to the 
correctness of the developmental history given by De Geer, 
notwithstanding that author expressly states that he had reared 
both pupa and imago. In the months of April and May of 
last year (1882) I was fortunate enough to capture the larva 
in various places in this neighbourhood and to rear the gnat, by 
which means it appeared that De Geer’s description was ex- 
actly in accordance with the truth. At present, however, I 
shall confine myself to describing the imago itself and indi- 
cating its place in the system, reserving the description of the 
larva and pupa for a general working up of the great number 
of midge and gnat larve upon which I have been at work for 
a long time, and which I hope to have ready in the course of 
the present year.
