our correspondent described as four different kinds of serious fungus 

 enemies, which considerably complicated matters. Early plantings of 

 cowpea were said to have been injured almost as badly as beans. It 

 was stated also, among other things, that farmers in north Alabama 

 no longer attempted planting cowpeas before June on account of the 

 injuries attributed to this insect. Velvet beans were growing side by 

 side with beans in plots on the Experiment Station grounds at Auburn, 

 Ala., and the former appeared to be entirely free from attack, while 

 the latter were badly injured. Exemption from attack on garden pea 

 had been noticed here as elsewhere. 



Occurrence in otke?* localities. — Among new localities where attack 

 on bean was observed during the year were Alexandria, Va., Travilah, 

 Md., and Louisiana, Mo. In the locality last mentioned, attack was 

 reported by Mr. G. M. Dodge in a letter dated November 21. 



At Bay Ridge, Md., the work of the beetle was evident on hog pea- 

 nut, Falcata comosa (Amphicarpwa monoica), and although the larva 

 was not found on this plant, the fact that no other known larval food 

 plant or other plant, affected by the beetle grew in the vicinity is 

 additional evidence that this is a true host plant of the larva. Beetles 

 taken at this time on the vines deposited eggs July 25. 



Early and late occurrences. — One observation on the occurrence of 

 the bean leaf -beetle near Washington was the appearance of a newly 

 transformed beetle June 30, which is nearly two weeks earlier than 

 observed in 1897. 



Beetles were taken as late as September 15, on which date considera- 

 ble injury was noticed on the young terminal leaves of Lima bean at 

 Cabin John, Md. 



NOTES ON THE IMBRICATED SNOUT-BEETLE. 



{Epicserus imbricatus Say.) 



This species, which was treated somewhat fully by the writer in 

 Bulletin 19, n. s. (pp. 62-67), has since come under observation on 

 several occasions, having been studied in connection with insects affect- 

 ing beans and peas. 



Adults were observed July 8, 1899, feeding upon bush beans at 

 Cabin John, Md., and two days later Mr. Pratt found the beetles at 

 Travilah, Md. , eating blossoms of Lima bean. All of the beetles seen 

 at this date were badly rubbed and such as were kept died a week or 

 two later, none remaining after the third week of July. July 29, 1899, 

 a newly transformed beetle, as its bright color indicated, was taken on 

 the foliage of tick trefoil (Jfeibomia sp.). 



Although the life history of this species is incomplete, we have the 

 principal data, with the exception of the most important — the larva and 

 pupa and larval food plant. The above observations show that the
