Dr. Hoy said galls were pathological appearances and rather dis- 
eases of plants; as much out of place in descriptive botany as a descrip- 
tion of cancer in a description of the lips. 
Dr. Morris remarked on the scarcity of larva and imagines of Lepi- 
‘doptera, which produced much discussion, and showed that while north- 
ward there had been no unusual dearth of insects, elsewhere all insects 
had been remarkably rare. Carduc was an exception and generally 
‘common. Mr. Aaron cited a remark of Mr. Ridings that he was always 
afraid of a season when carduz was abundant, for then, usually, nothing 
else would be found. 
Dr. Hoy remarked that in his locality (Racine, Wisc. ) he had 
found many inSects usually more southern, one started a crseuission pine 
the range of P. /urnus. 
The question then turned upon the food plants of P. ajax.’ Dr. 
Hoy said the pawpaw was not found within 200 miles of Racine, “while 
ax had often been found, still fresh and not fully developed. 
Mr. Aaron gave spice wood and upland huckleberry as further food 
‘plants. Dr. Hoy said they had the huckleberry but not the spice bush. 
Mr. Osborn had seen ajax but knew of neither huckleberry,- paw- 
paw or spice bush in the-vicinity of Ames, Ia., of the spice wood he was 
not sure—they might have it. He reports from Sioux City, that ‘there 
‘Chrysochus auratus is so common, that it is crushed under foot in the 
streets. Mr. Mann has seen them in woods in piles upon stones, : 
Mr. Saunders reports an abundance of H. ¢extor everywhere through 
Canada, and from West Canada an invasion of the larva of Gr apta pro- 
‘ene on currants, 
Mr. Greef exhibited some specimens of Lepidoptera, rare or typical 
of recently described forms. 
Sept. 8th.—Prof. Martin exhibited some specimens of gum copal 
‘containing imbedded insects, all of which appeared’ to be of a post terti- 
‘ary type. The gum is obtained near the equator, some distance from 
“the shore, by digging atthe site of old forests, long since extinct, 
‘the gum being the product of such trees. Among the’ Coleoptera Dr. 
Horn recognized a form allied to Calida, 2 Chrysomelids, 1 Clerus, 1 Cy- 
matodera, 2 Longicorns near Clytus and Leptura and an Elaterid much 
like one of our species of Cardiophorus. Mr. Smith recognized’ one of 
the Lepidopiera as a Mamestra, and the Hemiptera as representing common 
living types, one Homopterous species remarkably like a form now com- 
“mon'and in the Diptera a common Muserd type.
