insect. Coleoptera are numerous but inconspicuous. Cocci- 

 dae are also numerous, but there are probably no native spe- 

 cies. The temperature ranges from 58 to 84 F. and it is cool 

 and pleasant most months in the year. Hurricanes are dis- 

 agreeable as is also the intense sunlight. The introduction and 

 spread of lantana was mentioned. It soon became a pest and 

 was checked by insect life. A description was given of the 

 leaf-hopper pest and how it was checked. 



Dr. Calvert referred to the fact that a large percentage of 

 the Carabidae of the Hawaiian Islands were flightless and this 

 also applies to other oceanic islands. Mr. Rehn said Schisto- 

 cerca vaga on Clarion Island has wings only two thirds as long 

 as those found on the mainland. 



Dr. Calvert alluded to the work he has been carrying on in 

 relation to fossil dragon-flies in comparison with living spe- 

 cies. The very early remains of the Carboniferous period 

 were compared with recent forms and the differences pointed 

 out. He especially referred to Phenacolestes from Florissant. 

 The nearer the nodus is to the base of the wing the later the 

 dragon-fly usually is in geological time. The venation is dens- 

 er in the earlier forms and in the later there is a smaller num- 

 ber of veins. The venation in Ortholestes, Lestes and Enal- 

 laffma was compared and shown by enlarged drawings. 



Mr. Rehn spoke of the neuration of Protoblattina and the 

 present cock-roaches. Mr. Cresson said the Tipulidae were 

 considered to be quite ancient types of Diptera. 



Mr. G. M. Greene said that many chestnut trees in Fair- 

 mount Park had been cut down and from them on March 23rd 

 he had collected Ips fasciatus and other Coleoptera. 



Mr. West exhibited a number of species of Catocala taken 

 at Pitman Grove, New Jersey. He took eight relicta at 

 Cramer Hill, Camden County, N. J. 



Mr. Rehn referred to the Monthly Bulletin of the State 

 Commission of Horticulture of California, Vol. 2, Nos. I 

 and 2, and said that figure 19, labelled Microccntrum lauri- 

 folium, represents a species of Scudderia.
