to different localities and altitudes, he showed by comparing 

 the results of two collectors. Commencing at an altitude of 

 2500 feet he gradually worked up to an elevation of 6500 feet 

 until June when he left for Plumas Co., where he collected at 

 an altitude of 11500 feet. Of the three shipments received by 

 Mr. Franck the second and third shipment represented for the 

 greater part insects contained in the first shipment, the repeti- 

 tion of species showing a seasonal retardation corresponding 

 with the altitude in which they were collected. About 200 

 species of lepidoptera were taken. The following insects were 

 among those selected to illustrate the subject and were taken in 

 all the localities and altitudes visited by the collector : — 



Hepialus lenzi, Axenus arvalts, Melicleptria villosa, Syneda 

 edwardsi, Heliothis phlogophagus, Annaphila decia, Heliaca 

 diminutiva, Hemaris t/ietis, Plusia calif ornica. 



The second collector remained in one locality near Colorado

 while his catch did not exceed in number of specimens that of 

 the first collector, he secured 531 species.

Mr. Roberts spoke on the waterbeetles belonging to the 

 Haliplidae and he exhibited all the described species, save one 

 unknown to him, and nine new species with manuscript names. 

 In describing his methods for determining species he called 

 particular attention to the shape and incrassation of the front 

 and middle tarsi of the males, which are simple in the females 

 and are characters not heretofore used. Other characters men- 

 tioned were the markings on elytra., and the shape of the
