1893-] ENTOMOLOGICAL NEWS. 255 



C. V. Riley made some remarks on a San Jose scale, which has 

 made its appearance in Virginia during the present year. He 

 emphasized the fact that here was another case in which an inju- 

 rious insect could probably be completely stamped out of one 

 locality were there any authority with sufficient power to act 

 promptly and efficiently. This started some discussion as to the 

 value of legislation in matters of this character, and quite a di- 

 versity of opinion was shown to exist on the subject. Mr. H. 

 Garman described his method of preserving larvae for study, 

 which consisted essentially in killing them in boiling water, then 

 cutting through the skin and again boiling until the entire tissues 

 of the insect had become hardened and fixed. Miss M. E. Murt- 

 feldt read some notes on Piophila casei, in which she described 

 the attacks made by the larva of this insect on meats in smoke- 

 houses. 



Altogether six sessions were held on three days, and had there 

 been a longer time for meeting it could have been profitably 

 employed, since in order to allow the reading of all the papers it 

 became necessary in some cases to shorten discussion. J. B. S.

On the Larva of Notodonta stragula Grt. 

 By HARRISON G. DYAR. 



The mature larva of this species has been briefly described three 

 times,* but the authors are sadly at variance as to the location of 

 the discal humps on the anterior abdominal segments. Grote 

 locates them on joints 5 and 6, Edwards and Elliot on joints 7 

 and 8, while Packard finds them on joints 6 and 7. My obser- 

 vations agree with those of Dr. Packard. The other authors are 

 probably in error.

 appears closely, but irregularly punctured. Magnified 250 di-

 pyriform cells, followed by two more concentric rows of elongate 

 hexagonal cells. After these the regularity of the rows of cells
