Observations and Notes. 



Clathrulina elegans. — I found this most beautiful Rhizopod 

 April 30th, last, in a "brick pond" at Hamburg, this county. The 

 animals were hanging down by their almost colorless pedicles, at- 

 tached to the fibers of vaucheria; they were often in chains, the 

 founder of the colony fastened to the alga, while successive indi- 

 viduals clung to the "baskets " of those giving rise to them. Three 

 generations were seen thus attached. In this gathering I found 

 those self-dividing, so there were two, and in one case four exam- 

 ples in one nest. The young just beginning to build its house, and 

 its lattice-work as well, are perfectly colorless. 



Polyzoa. — I have identified from the Niagara, near the city, the 

 following species: 



Paludinella Ehrenbergii, Van Beneden. 

 Fredericella regina, Leidy. 

 Plumatella diffusa, Leidy. 

 Plumatella arathusa, Hyatt. 

 Plumatella vitrea, Hyatt. 

 Pectinatella magnifica, Leidy. 

 Cristatella ophidioidea, Hyatt. 



Phloeosinus liminaris, Harris. — Mr. W. W. Stanard called my at- 

 tention to a beetle doing much injury to the peach trees at La Salle, 

 N. Y. On visiting the orchards mentioned by him I found many 

 trees with their trunks covered with gum, exuded from the galleries 

 made by the beetle. Many trees were dying, apparently from that 

 enemy. Larva, pupa and beetle were found plentifully, late in Sep- 

 tember, 1880. The State Entomologist identified it. 



Heliothis armiger, Hiibn. — In July last the larva of the " corn 

 worm " at Corunna, Michigan, was so abundant that early corn was 

 considerably damaged. In one field I found more than half the 

 ears had been eaten into by it. (See Riley, Ins. Mo., III., 104.) 



Aletia argillacia, Hiibn. — The moth was abundant about Buffalo 

 from September 10th to the end of November.
