populous, a single one containing between 70 and 100 specimens, 

 but the males appear to be just as rare as in Xyleborus. 



In one instance another borer in Phoradendron twigs was met 

 with, viz., a Bostrychid larva. This was bred and produced a 

 somewhat crippled specimen of an undescribed species of Am- 

 phicerus. The species was not met with elsewhere in Arizona, 

 but is probably not peculiar to the mistletoe. 



The Californian Psyllid mentioned above was not observed at 

 any place visited by me in Arizona, but a Lycaenid larva was not 

 rare feeding on the leaves of Phoradendron. Several imagoes 

 were bred, and Dr. Dyar determined the same as Thecla halesus. 



Mr. Dyar stated that the published records show the food plant 

 of this Thecla larva to be oak. This he thought probably was a 

 mistake and mistletoe is its true food. Mr. Ashmead said that 

 the live oaks in the city of Jacksonville, Fla.^ were covered with 

 mistletoe, especially at the tops. He has seen a scale insect and 

 an Aphid on the mistletoe, but has never worked either of them up. 



Mr. Pollard asked whether any insects were known to feed up 

 on the Spanish moss (Tillandsia) in the South. Messrs. Ash- 

 mead and Schwarz replied that this moss is full of insects, but 

 they thought that none of them feed upon it, although Mr. Schwarz 

 stated that Monocrepidius vcspcrtinus eats the leaves occasion 

 ally. Mr. Morris stated that in the moss used in packing he had 

 seen a breaking or eating of the ripened pods, but was not sure 

 that it was caused by insects. 



Mr. Schwarz read the following letter written by Mr. Hubbard 

 in 1894, on the fauna of Florida caves : 



INSECT LIFE IN FLORIDA CAVES.

CRESCENT CITY? FLA., July 31, 1894. 



I found so much to do at Eustis with Webber and Swingle that 

 I spent four or five days with them in the laboratory. Just as I 

 was thinking of leaving them, Mr. Swingle received a letter from 

 an old-time guide of his telling about some large caves in Her- 

 nando and Citrus counties. As they are only 30 or 40 miles west 

 of Eustis, we concluded to visit them and explore, but we found 

 much trouble in getting there. However, we reached Istachatta 

 on the Withlacoochie river after a night's traveling. We found 

 here extensive but shallow and muddy caves. I should say about
