a mean skunk from pilfering, or to go through the clothes of 

 every person as he finishes studying a collection. Such a 

 course would be oflfensive to the many visitors to a museum 

 who come for legitimate study and comparison. Many insects 

 are quite small and readily concealed and some weasel may 

 quickly slip into a box the things he covets to fill out the blank 

 spaces in his own collection. We can only repeat with shame 

 that such degraded persons exist among those who are sup- 

 posed to truly love nature and science for their own sakes. 

 Theft is as far from the thoughts of the true naturalist as 

 murder. — Henry Skinner.

Under the above head it is intended to note papers received at the 

 Academy of Natural Sciences, of Philadelphia, pertaining to the En- 

 tomology of the Americas (North and South), including Arachnida and 

 Myriopoda. Articles irrelevant to American entomology will not be noted; 

 but contributions to anatomy, physiology and embryology of insects, 

 however, whether relating to American or exotic species, will be re- 

 corded. 



The numbers in Heavy- Faced Type refer to the journals, as numbered 

 in the following list, in which the papers are published. 



All ccTntinued papeis, with few exceptions, are recorded only at their

 of Mexico are all grouped at the end of each Order of which they treat.
