Acanthocinus aedilis. The larva of this beetle is a wood- 
borer, making, according to Rye, “ wide galleries and per- 
forations in pine stumps.” The perfect insect is remarkable 
for the great length of the antennse, which in males are 
often, as in this instance, four inches long, i.e. four times the 
length of the body. It is said to have been found near 
Accrington, but is rare in England, its head quarters being 
apparently at Rannoch in Scotland. One was found by a 
servant when going down the cellar steps of a house at 
Runcorn, and unfortunately killed by her in her alarm at 
such an insect alighting on her neck. Another — The one 
sent to me — was found almost immediately afterwards by 
some one else going into the cellar, and secured alive. It is 
curious for them to occur in such a situation. A possible 
hypothesis may be that they had lain concealed in the tim- 
ber in the pupa condition, and had just made their exit. This 
is rendered less unlikely by the fact of the house being new, 
especially if the timber were “ green.” 
Dr. Alcock exhibited a full-grown male Gonoplax 
angulata. He found this crab about two months ago at 
Southport, on the sandbank known by the name of the 
“Seldom Seen.” A specimen of it is understood to have 
been found many years ago, by the late Mr. Greaves, on the 
shore at Southport, but no second example has been 
recorded until the present one. Mr. Arnold Millson, who 
being a resident has had constant opportunities of visiting 
the shore at all seasons, states that he has seen several of 
these crabs at different times, but had not preserved them. 
Dr. Alcock also mentioned that all the jelly-fishes seen
