.-\n e.xcellent idea fo- publications of local 

 scientific societies is carried out by the Verein 

 fiir naturkunde zu Cassel, in its Bericht for 

 1SS3 to 18S4. Over one-half of this Bericht 

 is devoted to a list, by Dr. Carl Ackermann, 

 of scientific works of all kinds pertaining 

 to Cassel and itsvicinity. In the portion of 

 the list devoted to the distribution of animals 

 is to be tound mention of man\' pajjers upon 

 the insect faima of (he above-mentioned re- 

 gion. 



At the Montreal meeting of the ISritish 

 association ff?i' the athancement of science 

 but one entomological paper \\as )-ead- 

 Tliis paper. -'A contribution to our knowledge 

 ol the fhylopti." was by Prof. Playfair Mc- 

 .Murrick, of Guelph, Ontario, Canada. En- 

 tomology was better represented at the 

 Philadelphia meeting of the American asso- 



ciation for the advancement of science, Dr. 

 C. S. Minot read a paper "On the skin of 

 insects"; Prof. Geo. Macloskie. on "The 

 dynamics of the insect-crust"; Dr. C. V. 

 Riley, ''On the hitherto unknown mode of 

 oviposition in the carahidae" ; and Lillie J. 

 Martin, a paper entitled, "A botanical study 

 of the mite-gall found on the petiole of 

 yiiglaiia iiigi-a. known as Erineiim aiiomaliim 

 Schw. 



At a recent meeting of the Baltimore 

 Naturalists' field club, Mr. Otto Lugger gave 

 an account of a strange hymenopterous par- 

 asite infesting the larva of Tipi/iia. The 

 Tiphia lavs its eggs in the larva oi Lacknos- 

 tenia fiisca: the larva of Tiphia when nearly 

 mature eats the white grub and then spins for 

 itself a beautiful silken cocoon. This larva 

 in turn is often infested by the lar\a 

 Rkipipliiftus pcctiiiatus or R. limtatiis, the 

 eggs of which have become fastened to the 

 Tiphia, and in this way reach the Tiphia 

 cocoon. Mr. Lugger has also found in the 

 same cocoons small hymenopterous parasites. 

 The order of events in this case appears to be 

 that the larva of a large coleopterous insect 

 is destroyed by a hymenopterous larva, this 

 in turn b\' a coleopterous lar\'a. and this 

 again by a hymenopterous larva. — Science

 BUTIONS.

 resident in Cambridge, expects from North 

 American entomologists a support as liberal
