the group; they were ranged around the empty egg shells. These 

 shells were all together, like the cells of a honey comb, and one end 

 of each had been broken by the young as it emerged. 



"Close to the egg shells and the young bugs was the mother. The 

 entire group for the most part remained motionless and apparently 

 lifeless. She neither brooded over the young, nor did the young 

 crawl over the mother's body. Occasionally, however, one of the 

 young would move and in so doing would disturb the others; except 

 for this they remained motionless. The mother remained in the same 

 position almost all the time; only a few times did she slightly shift her 

 position to one side or the other." 



With food abundant at hand, there was little occasion for much 

 activity and still I hardly think it was entirely due to this cause that 

 the mother remained with the brood into the second instar. While 

 it is possible that the whole phenomenon is accidental, there is some 

 probability that this is an actual case of maternal solicitude in this 

 insect. 



Further observations will have to decide whether the mother's close 

 proximity to her brood is one of maternal solicitude or only one of 

 physical economy. PHIL RAU, St. Louis, Missouri.

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, how- 

 ever, whether relating to American or exotic species, will be recorded. 



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

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



All continued papers, with few exceptions, are recorded only at their 

 first installments. 



The records of papers containing new species are all grouped at the 

 end of each Order of which they treat. Unless mentioned in the title, 

 the number of the new species occurring north of Mexico is given at 

 end of title, within brackets.
