ing the work of an undescribed Scolytid beetle of the genus Pity- 
ophthorus. The galleries which are partly in the bark and partly 
in the outermost layer of the wood are the primary galleries, i. e., 
those made by the parent beetle, and exhibited a feature hitherto 
not observed in any other Scolytid. The female beetle bores 
straight through the bark ; then follows a very short gallery ver- 
tically downward, and this is crossed immediately below the 
entrance hole by an extremely long transverse gallery. The 
novelty consists in the short t vertical gallery, which evidently is 
constructed only for the purpose of enabling the beetle to turn 
around without getting on the outside of the tree. The larval gal- 
leries, if there be any, are not yet known. 
The new species belongs to LeConte's group B, and may be called Pity- 
ophthorus querciperda. It is closely allied to P. minutissimus, with which 
it agrees in size, form, and coloration, but from which it differs in the 
sculpture and pubescence of the elytra. In minutissimus the elytra are finely 
and rather indistinctly punctulate ; the pubescence is fine, very sparse or 
nearly absent on the basal portion of the elytra, and denser on the decliv- 
ity, but always hair-like. In querciperda the elytra are quite distinctly 
rugosely punctulate, and, therefore, less shining. The pubescence is 
stout, moderately dense on the anterior part of the elytra and still denser 
and scale-like on the declivity. In the two Californian species of the same 
group the pubescence consists of long and short hair intermixed. P. 
querciperda occurs from New York to Florida.

Eight persons present. President Howard in the chair. 
Mr. A. Bolter, of Chicago, 111., was elected a member of the 
Society. 
Referring to the nuisance created this season by Dynastes 
tityus, Mr. Howard remarked that the smell had also been quite 
noticeable this season at Raleigh, N. C., on a street lined with 
Hackberry trees ( Celtis ) . Mr. Smith asked whether the larvae 
of Dynastes mature in one or several seasons. He knew, from 
actual observations made by himself and Mr. Schaupp, that Luca- 
nus dama has a period of at least two years. Mr. Schwarz said 
that, so far as he was aware, no observations had hitherto been 
published on the duration of the larval state in Dynastes. Mr.
