Mr. Howard said that the present time was unquestionably 

 the most favorable for the establishment of this insect within our 

 boundaries that had existed. One result of the destruction of 

 the orange trees in Florida by last winter's freeze has been to 

 send orange buyers to neighboring tropical countries and that a 

 number of them had gone to Mexico, with the result that last 

 spring and the present winter there has been an enormous 

 shipment of Mexican oranges into the United States. He told 

 of one English buyer who had gone direct to the State of More- 

 los, and had been shipping oranges by the wholesale into this 

 country. He further mentioned recent newspaper accounts of 

 the rinding of what is undoubtedly this same insect in oranges 

 used for table purposes in Cincinnati. 



Messrs. Ashmead, Swingle, and Schwarz further discussed 

 the probability of introduction and showed that Mexican oranges 

 are actually in use in great numbers in Florida, especially in the 

 large hotels.

A NEW CAVE-INHABITING SILPHID. 

 By E. A. SCHWARZ. 



While the caves of Europe are inhabited by many remarkable 

 genera and species of Silphidag, the pretty thorough exploration 

 of many North American caves has produced only a single pecu 

 liar species of this family, Adelops hirtus Tellk. which is quite 

 abundant in most caves of the Green River basin of Kentucky. 

 It bears all characteristics of a true cave insect except that the 

 eyes are feebly developed. Another Silphid, Choleva alsiosa 

 Horn, occurs in various caves of Kentucky and Indiana, but it 

 does not differ structurally from its congeners which live above 

 ground in decaying fungi and under vegetable debris. Moreover, 

 it was originally described from the Yukon River of Alaska, 

 where there are no caves. It is interesting, therefore, to record
