Hal)its of some social insects, and the polity 

 of the hive of the honey bee. Refers to instincts 

 of many social insects, and concludes tliat in- 

 stinctive and inevitable actions on the part of 

 insects are associated with others which result 

 from the possession of intelligence, of conscious 

 reasoning and reflective powers. 



"Just among the mammalia, the higher intel- 

 lectual development, as in man, is physiologic- 

 ally correlated with the longest period of de- 

 pendent infancy ; that this helpless infancy has 

 been, in fact, a' prime influence in the origin, 

 through family, clan, tribe, and state, of organ- 

 ized civilization; so in the insect world we tind 

 the same physiological correlation between the 

 highest intelligence and dependent infancy, and 

 are.] ustifled in concluding that the latter is in t lie 

 same way the cause of the high organization ami 

 division of labor, the cause and explanation 

 which so baffled Darwin in the application of his 

 grand theory of evolution to social insects."

Parasitism in insects. Annual ad- 

 dress of the president. 



I'roc. Ent. Soc. Wash., u, No. 4, June, 1893, 

 pp. 397-431. Also separate, pp. 1-35. 

 A general consideration of the subject of par- 

 asitism among arthropods. As a useful work- 

 ing system the author divides insect parasites 

 into: I. Parasites proper, or those which cm 

 not exist apart from the host; II. Fatal para- 

 .sites, which as a rule involve the death of the 

 host; and III. luquilmous parasites, including 

 those insects which sponge on the labors of 

 other insects. These primary divisions permit 

 of subdivision, and the subject is dealt with in 

 detail under the following subheads : Animals 

 affected ; the jjarasites among insects, dealt with 

 by orders; the derivative origin of inject para- 

 sitism; eflects of the parasitic life; economic 

 bearing of j)arasitism: conclusions. 



Is Megastigmus phytophagicf. 



I'voc. Ent. Soc. Wash., u, No. 4, June, 1893, 

 pp. 359-363. 

 The author presents facts gathered from Her- 

 man Borries, of Denmark, the writings of Par- 

 fitt, Mayr and Wachtl, and his own observa- 

 tions, and concludes that while there is every 

 reason to believe that the genus is essentially 

 parasitic, some of its species may be ])liyto- 

 l>hagic.
