though the venation of the wings and the larvae are essentially 
sphingiform.* 
Mr. Smith also stated that he had found that among the insects 
usually named Euerysthia phasma, two species were embraced 
which differed decidedly, not only in markings, but in structure. f 
Mr. Smith also offered some remarks on the North American 
species of Callimorpha. In arranging the material of the U. S. 
National Museum he had come to the conclusion, from a study 
of the series of Callimorpha in the collection, that most of those 
forms now marked as varieties were really good species. He 
said that, at some future time, he would present a careful study 
of the forms. | 
Mr. Schwarz presented the following list of Scolytids found by 
him on Pinus inops, in the vicinity of Washington : Gnatho- 
trichus materiarius, asperulus, Pityophthorus sparsus,pullus, 
hirticeps, puberulus, Hypothenemus dissimilis, Xyloterus 
bivittatus (probably imported from farther north), Xyleboriis 
pubescens, ccelatus, Dryoccetes affaber, Tomicus calligraphus, 
cacographus, pint, Carphoborus bifurcus, Dendroctonus tere- 
brans, Hylastes porculus, tenuis* Hylurgops pinifex. The 
mode of work of many of these still remains unknown. Among 
the less common species is Pityophthorus pullus, the galleries 
of which were exhibited and explained. The female beetle (or 
both sexes ?) constructs under the bark of the trunk a rather large, 
round or oval central chamber, from which from three to five long 
and slightly undulating galleries lead off in various directions, but 
usually more or less upwards or downwards. The larval galleries 
do not present any particular features, but are rather shorter than 
in allied species. All these galleries are more within the bark 
than in the outermost layer of wood.
