 the life of Juan Gundlach in ENTOMOLOGICAL NEWS for 1915, including 

 a list of his papers, among which is one on Cuban Neuroptera. The

 to the collection, also a box containing the specimens figured in the 

 colored plate in Dr. Calvert's "A Year of Costa Rican Natural His- 

 tory," which have been deposited in the collection. 



Mr. Laurent stated that from cocoons of Philosamia cynlhla gath- 

 ered on September Sth, three moths emerged on September 29th and 

 30th, due no doubt to the warm weather prevailing the last half of the 

 month. The speaker said that under ordinary conditions these moths 

 would not have emerged until next year, as the species is single 

 brooded in this vicinity. 



Orthoptera. A series of the handsome grasshopper Schistocerca 

 nieldi'ocera (Stal) was shown by Mr. Hebard. The species is known 

 only from the Galapagos Islands. Differences in coloration were 

 pointed out and genetic factors and local environmental influences 

 were said to be the causes of these. That other species divide into 

 very interesting insular races on different islands of the Galapagos 

 Archipelago was remarked. 



Hymenoptera. Mr. Rehn made a few remarks 011 the similarity of 

 the white-haired Mutillids of the Southwestern United States to the 

 seed pods of the creosote bush (Co-rill ca tridentata).
