time well populated, but not for any length 

 of time occupied by the people whose ruined 

 buildings of stone are found in the region 

 up to southern Mexico, and that it was 

 visited by several distinct peoples in ancient 

 times. Some mounds covered with stone 

 were discovered which deserve further in- 

 vestigation. Five caves cf different size and 

 character, described in the second memoir, 

 were explored near Copan, and afforded 

 objects peculiar to themselves and evidences 

 of sepulture. They were very dusty, al- 

 though stalactites had formed in some of 

 them, and, although undoubtedly used by 

 man many centuries ago, they do not seem 

 to indicate a constant occupation for an ex- 

 tended period of time, or to furnish evidence 

 of an extreme antiquity of man in the re- 

 gion. The most striking feature about them 

 is probably the entire difference in character 

 of the pottery from that found at Copan, 

 only a few miles away, and its want of re- 

 semblance with the pottery of any other 

 locality with which the author is familiar. 



A series of Bulletins, Some Miscellaneous 

 Results of the Work of the Division of En- 

 tomology, of the United States Department 

 of Agriculture, is intended to furnish such 

 material as was formerly published in Insect 

 Life, presenting the results of observations 

 made in the office of the bureau which are 

 not extensive enough upon any one topic to 

 form an independent and complete bulletin. 

 The second number contains notices by dif- 

 ferent authors, mostly connected with the 

 bureau, on twelve insects predatory on eco- 

 nomical plants, with numerous "general 

 notes " and correspondence. 



Under the Stars, and Other Verses, is a 

 small collection of ballads, relating chiefly 

 to naval fights, by Wallace Rice and Barrett 

 Eastman, published by Way & Williams, 

 Chicago. It is dedicated " to the wider pa- 

 triotism," and appears well adapted to inflame 

 the martial spirit, which is in this country 

 already excited to an extremely unhealthy 

 extent.
