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.—Puit Rau, St. Louis, Missouri.

Entomological Literature. 
COMPILED BY E. T. CRESSON, JR., AND J. A. G. REHN. 
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.

tomology, Series A, London. For records of papers on Medical Ento- 
mology, see Review of Applied Entomology, Series B.
