work done by these parasites. Remarks and discussions by Messrs. 

 Hebard, Cresson, Skinner and Hornig followed, especially dwelling on 

 the general ineffectiveness of quarantine for the control of insect pests. 



Meeting of May 27, 1920, with Director Philip Laurent presiding. 

 Mr. David E. Harrower was elected a member. 



LEPIDOPTERA. Mr. Coxey exhibited a specimen of Papilio laglaizci 

 Dep. from New Guinea, which strongly mimics a moth of the genus 

 Nyctalcmon. Dr. Skinner made some remarks on the synonymy and 

 distribution in the Hesperidae. He spoke about the difficulty he ex- 

 perienced in trying to establish some of the old species on account of 

 their inadequate descriptions and the uncertainty of determined mate- 

 rial. He emphasized that care should be exercised in taking for granted 

 the determinations of others. 



ORTHOPTERA. Mr. Rehn spoke about his recent studies in the groups 

 allied to the genus Trimerotropis. 



Meeting of September 23, 1920. Vice-Director R. C. Williams presid- 

 ing. Dr. Charles T. Ramsden, of Guantanamo, Cuba, a visitor. 



Dr. Skinner gave a short account of his summer trip to the Sierra 

 La Sal mountains of Utah. He mentioned some of the insects collected, 

 especially the Lepidoptera, but found the country dry and insect life 

 scarce. Discussion and remarks by Messrs. Hebard and Williams. Mr. 

 Cresson exhibited a recently acquired book, Smgulorum Genera Curcu- 

 lionidum, by Labrum & Imhoff. This work was originally issued in 

 nineteen fascicles, appearing from 1828 to 1845, and contains descrip- 

 tions and figures of some new species. In the general arrangement in 

 which this work was bound, and quoted in the literature, the actual 

 dates- of publication were not secured. Mr. Rehn mentioned other 

 works of which the dates of issue were difficult or impossible to obtain. 



LEPIDOPTERA. Dr. Ramsden made some interesting remarks on his 

 experiences in collecting at light in Cuba. He found that certain kinds 

 of light were better than others, which, he thinks, is due more to the 

 color or quality than to the strength. He spoke of the curious habits 

 of some moths at light, especially at certain periods of the night. He 

 said that sometimes one could pick the specimens by hand much better 

 than catching by net. Discussion by Messrs. Hebard, Hornig and 

 others, especially on collecting Sphingidae. Mr. Lorup exhibited two 

 specimens of Prionoxystus robiniae and Linicnitis artlicmis. The latter. 

 he said, was found dead last Labor Day at Folcroft, Delaware County, 

 Pennsylvania.

 roimnon house cricket, especially in tin- tropics; th;U strenuous mi
