216 ENTOMOLOGICAL NEWS. [May, ’o8 
and also from Mr. L. E. Anthony, Smyrna, Del. The insects 
did not make mines of any particular shape, but destroyed the 
whole inner portion of the leaves, the upper and lower epider- 
mis of the leaf only remaining. 
The leaves were sent to me in a letter and all the insects 
had escaped. I endeavored to secure leaves that contained the 
insects, but was unable to do so. Mr. Emerson informs me that 
several blackberry plantations in that vicinity were quite badly 
infested and fears were entertained that serious damage would 
result if the insects continued to increase. I shall make care- 
ful observations during the coming season in the infested plan- 
tations.” 
This probably refers to this species, and is doubtless the first 
published reference to an injury by S. capitalis which could 
be considered as being of economic importance. 
Owing to my failure in 1906 to secure the data that I desired 
relative to the life history of this leaf-miner, I made plans to 
carefully study the species in 1907; but owing to the unusually 
cold and wet spring weather that we had, or other unknown 
causes, the miner appeared in only very small numbers the 
past season. At the time of my first visit, June 4, I failed to 
find any of the adults or any signs of mines. On the 27th of 
June I again visited the place and spent considerable time in 
the field, but found only six or eight leaves that contained 
mines. One or two of the larvae in these appeared to be nearly 
full grown at this date. Some of the infested leaves were 
brought home and placed in a glass cylinder with cotton batting 
at top and bottom, and this was set away in my laboratory. 
On July oth I found therein a specimen of a species of Rhy- 
sipolis* which had apparently just emerged. This is therefore, 
presumably a parasite upon the larvae of S. capitalis. 
Notes on Pachybrachys. 
By Frep. C. Bowpitcu. 
These preliminary notes are in the hope that collectors will 
give this neglected group some attention during the coming 
season, by collecting series of specimens with special reference 
to the locality and food plant and so facilitate further and 
more complete study of this genus.
