out were the four lateral and one posterior median, and all of 
these were unpigmented, and looked as if they were practically 
undeveloped. Traces of the other eye-spots were to be seen, 
however. In neither case could any scar be found to indicate the 
loss of the eyes from traumatism. 
Dr. Marx called attention to a mutilated specimen of Lycosa 
sp. which he had spoken of in a previous meeting of the Society. 
In this case the large eyes of the second row were wanting, but a 
cicatricial line was found, showing that they had been removed by 
a traumatism. 
Dr. Marx then read a letter from Prof. Thorell, in which the 
writer discussed the family terminations, idee and oidce, giving 
his decision in favor of the latter (oidce} . Dr. Marx called atten- 
tion to the conflict of the two names Epeiroides (genus) and 
Epciroidce (family) which would occur in this case, and said 
that with the termination of idee for the family, these would be 
entirely distinct. 
After much discussion, participated in by all the members 
present, the unanimous opinion was in favor of the termination 
idee. 
Mr. Schwarz read the following letter from Dr. Geo. H. Horn,, 
of Philadelphia, in regard to the breeding habit of a rare Ceram- 
bycid : 
" Early last spring Mr. G. R. Pilate, of San Bernardino, Cal., sent me a 
lot of stems of Opuntia bernardina from southern California, containing 
living larvae of Ccenopceus Palmeri. One of these, with the stem and 'an 
imago, I sent to Dr. Hagen for certain preservation with his already large 
biological series. The other stems were allowed to remain in the box neg- 
lected, knowing it would be useless to attempt to keep them green and 
growing. 
" On August 15 the box was opened again, and one very lively imago 
was found and four others dead or nearly so. 
" It is probable that the first emerged about August T. From this it is 
probable that in the much hotter climate of the Opuntia region the insect 
may be looked for a month earlier." 
Mr. Schwarz said that the food-habits of this species were very 
remarkable, since all other species of this group (Acant/iocinini) 
so far as known, live under bark of various kinds of dying or dead 
trees. The number of beetles known to bore in Opuntia stems is
