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 6\ 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 9th 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 FRED. C. BOWDITCH. 



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.
