60 THE ENTOMOLOGIST. 
discovered in two of his greenhouses, among vines planted 
in 1869, sufficiently distant from each other to render it 
improbable that the insect had been communicated one from 
the other; and he therefore concluded that the disease had 
been introduced in 1869 from the graperies in England. The 
vines so attacked had, however, not succumbed to the disease, 
but were simply rather weaker than those which had not been 
attacked. He was, therefore, anxious to ascertain whether 
the vines in the English graperies were less influenced than 
those out of doors; but none of the members present were 
aware of the occurrence of the insect in England out of doors, 
but that it had hitherto appeared in greenhouses only. 
Synonymical Notes on Longicorn Coleoptera.—Mrx. C. O. 
Waterhouse communicated the following :— 
“Fam. PRIONIDE. 
Acanthophorus Palinii, Hope—This species was placed 
by Mr. Adam White, with doubt, as Acanthophorus Yolofus 
of Dalman, and in Gemminger and Harold’s ‘ Catalogue of 
Coleoptera’ they are placed together without even a doubt. 
There being, however, in the British Museum a species of 
Tithoés (to which genus A. Palinii must now be referred), 
which I believed to be the true A. Palinii, I referred to Prof. 
Westwood, who kindly sent to me a sketch of Hope’s type in 
the Oxford Museum, confirming my determination, and 
making it certain that A. Yolofus and A. Palinii are quite 
distinct species. Tithoés Palinii resembles T. confinis, but 
is shorter; the eyes are much approximated above; the 
thorax is broadest in front, with the anterior spine strong 
(much longer than the lateral spine), and very much recurved ; 
the elytra are marked much in the same way, but the apex of 
each elytron is less rounded, and there is a small tooth at the 
sutural angle. Length 1 inch 10 lines; width 8 lines. 
Habitat, Sierra Leone. 
Acanthophorus capensis, White.—This species is correctly 
placed in that genus, and does not belong to Tithoés, as 
placed in Gemminger’s Catalogue. 
Mallodon Gnatho, White.—This insect must be placed in 
Lacordaire’s genus Nothopleurus (Gen. d. Col. viii. p. 128). 
As nothing is said by Lacordaire about the form of the 
mandibles in the description of N. ebeninus, it will probably
