Pimpernel (. Anayallis anwurix), Wild Chervil (Chaerophi/llinn sylvestre), 
Mountain laurel ( Camia latifolia), and very many other plants, are 
dangerous. 
In conclusion we must admit it is somewhat of a large subject to 
treat in a small paper with any success, and we can only say that if 
any of the facts we have recorded lead indirectly to a greater interest 
being taken in our poisonous plants, Ave shall have been amply repaid 
for our labour. 
THE LIFE-HISTORY OF OPORABIA (EPIRRITA) AUTUMNATA, Bkh. 
(Bead March 21st, 1899, by LOUIS B. PEOUT, F.E.S.). 
The notes which I propose, under the above title, to bring before 
this Society this evening, may be regarded as supplementary to the 
general paper on “The Genus Oporabia,” which I read here on May 
4th, 1897, and of which the more important part was published in the 
Entom. llecord, ix., pp. 247, 282, 315, readily accessible to our 
members." 
1. In Kntom. xxx., p. 234 (Sept., 1897), Mr. Kane records what is 
obviously the true autumnata, Bkh., under the name autumnaria, Gn., 
as occurring near Belfast. 
2. In Knt. lice., x., p. 93 (April, 1898) I wrote some critical notes 
on the synonymy, the gist of which was that autumnata, Bkh.= 
autumnaria, Wea Y. = addcndaria, White — approximaria, Weav., and 
that the specific distinctness herefrom of autumnata, Gn., no. 1334, 
pi. 18, fig. 7, and oi nliyranmaria, H.S., still remained doubtful. 
The life-history which I have worked out does not prove Epirrita 
autumnata to be a species absolutely distinct from E. filii/rammaria ; 
probably the two stand in just about the same relationship as do many 
of our other most puzzling pairs of forms, e.y., Anthroeera trifolii and 
palitsitrix, Laniocampa qucrcri* and callunae, Tcphrosia bistortata and 
crepumdaria, Ac.; that is to say, they are differentiated by localities, 
periods, food-plants, markings, Ac., but not yet by important structural 
characters. 
Apart, however, from the extreme jiili<jrammaria development, the 
species before us appears to be rather liable to form local races, and as 
such the appro.rimaria of Weaver, the autumnata of Guenee (t/ueneata, 
rnihi) and perhaps also addcndaria, B. White, may probably be 
regarded ; in any case, I have now full confidence in referring them 
all to this species, and (without the minute varietal separations) I have 
given the synonymy in Entom., xxxiii., p. 63; I shall hope to work¬ 
out the details of the variation on some future occasion. 
It is hard to give an adequate description of this infinitely variable 
* Since writing this J have added another lengthy contribution, in Kntom. 
xxxiii., pp. 53-01, pi. i-ii (March, 1900).
