nictitans group of the Genus Hydroecia. 741 
an autumn holiday in 1899 collecting upon and around the 
Crinan Canal. The specimens were placed in my cabinet 
and there rested for a time. Puzzled about the curious 
resemblance between the three series, I appealed to Mr. 
Tutt, who could give me his convictions, but no certainties. 
I appealed to Mr. F. N. Pierce, already widely known for 
his unceasing investigations, and found that he had only 
nictitans and had come to the conclusion that there was 
but one species after all. We vigorously attacked the 
problem from this new standpoint, and, using Mr. Bacot’s 
material, I was surprised to find that I had stumbled upon 
a development of genitalia entirely different to nictitans, 
paludis and lucens. My discovery was announced in the 
“ Entomologist’s Record,” vol. xx, p. 146 (1908); the insects 
were exhibited before the City of London Entomological 
Society, March 17th and May 22nd, and before the South 
London Entomological Society on April 13th of the same 
year. After due consideration the new insect was named 
Hydroecia crinanensis (after the locality in which it was 
first detected) in the “Entom. Record,” vol. xx, p. 184. 
I give the following description of the specimen I have 
selected as type ; previous descriptions having been only 
comparative with the other species of the group. 
¢. Hydroecia crinanensis, Burrows. Larger than H. nictitans. 
F.-w. slightly pointed at the apex, bright red-brown, longitudinal 
and transverse lines very distinct, fringes concolorous. Orbicular 
stigma, lighter than the ground-colour. Reniform stigma orange, 
full, fairly straight edged inwardly, lower lobe projecting outwardly, 
interior dividing lines faint. H.-w. red-brown, darker towards the 
_outer margin ; fringes yellow, the yellow colour intruding in dots 
upon the darker margin. 
Type specimen taken by Mr. A. W. Bacot at Crinan 
Canal, September 1899. 
In the same magazine, vol. xxi (1910), p. 80, is 
published an article by myself, describing and naming 
nine distinct forms. 
Later, in the last-mentioned magazine, vol. xxii, p. 54 
(1910), Mr. Tutt reviewed the position and unreservedly 
accepted our conclusions. This acceptance he kindly 
emphasised by his address before this Society before 
referred to. 
This appears to have been Mr. Tutt’s last word upon
