exceedingly abundant at Tangiers, and the pedestrian was often ankle-deep 
in the dead and dying on the shore. The natives destroyed them with 
wisps of straw, and did not dig trenches to stop their ravages. Mr. 
M’Lachlan having remarked that the Chinese held, or did hold, an opinion - 
that locusts were developed from the eggs of craw-fish, Mr. Blackmore said 
that the Spanish word ‘langosta’ was used both for a locust and lobster. 
Mr. Druce exhibited several rare species of exotic Rhopalocera, the 
most interesting being Euryades Reevi, Westwood, Heliconia Hermogenes, 
Hewitson, Heliconia, n.s., Eresia, n. s. (2), Catagramma, n. s. (2), Agrias . 
Amydon, Hew., Paphia Panarista, Hew., Paphia nobilis, Bates, Siderone 
Mars, Hew., &c. ; 
Mr. Stainton exhibited (on behalf of its captor, the Rey. R. P. Murray) 
an example of Botys fuscalis, from the Isle of Man, to the head of which 
still adhered a portion of the puparium. The antenne and haustellum 
were free, but the case of the latter projected perpendicularly from the 
under side of the head, simulating the rostrum of a Panorpa. The insect 
must have been nearly blind, yet it was flying briskly at the time of 
capture. 
Mr. Miiller exhibited a vine-leaf from Basle, attacked by Phytoptus 
vitis, which causes fur-like spots on the leaves, known as Erineum vitis. 
Mr. Riley, State Entomologist for Missouri (present as a visitor), 
exhibited a large collection of North American insects, illustrating, in many 
cases, their transformations. Among them was a coleopterous larva, which 
Dr. Leconte (who was present) stated to be that of Pyrochroa flabellata. 
Mr. Dunning read the following extract from the ‘Times’ of 27th 
June :—‘ Under the pressure of necessity a Salt Lake City blacksmith has 
invented a machine to kill grasshoppers. It can be manufactured for 
seventy-five dollars. It consists of a frame drawn by two horses, haying 
an apron extending forward close to the ground to scrape up the locusts, 
with a hood above it, forming a box open in front. At the rear of the 
machine is a pair of rollers geared together, the upper one driven by the 
carrying wheels, of which it forms the axle. Whatever may find its way 
into the front of the machine is obliged to pass between the rollers at the 
back, which, being capable of being forced close together, are described as 
completely demoralizing the ‘ ironclads.’” 
Mr. Dunning also read a letter he had received from the Rev. W. H. 
Wayne, of Much Wenlock, stating that both this year and last his ripe 
strawberries were infested by a small Myriopod, which entered into the 
interior; there were often six or eight in one strawberry, and they were 
often eaten without detection. Mr. Wayne also stated that his young © 
carrots were injured by what he seemed to consider the same creature, but, 
from examples he sent, the depredators in this case were evidently the 
larve of a Dipterous insect, Psila rose. The larve first showed their
