386 THE ZOOLOGIST. 



is chiefly devoted to contributions to the Hemipterous Fauna of Iowa, and 

 principally to the Homopterous Family Jassidae, " which swarm, often by 

 millions to the acre, upon various species of grasses." 



The Committee for Protection of Insects in danger of Extermination, 

 of which Mr. Chas. G. Barrett is Hon. Sec, and to whom we are indebted 

 for the following information, recently held a meeting, and resolved that the^ 

 following species of Lepidoptera, being local species in danger of exter- 

 mination, be more particularly recommended for protection : — 



Papilio machaon, L. Nola albulalis, Hiibn. 



Leucophasia sinapis, L. Eulepia cribrum, L. 



Pieris cratcegi, L. Porthesia chrysorrhcea, L. 



Melitcea athalia, Esp. Clisiocampa castrenis, L. 



M. cinxia, L. Drepana sicula, Sen iff. 



Apatura iris, L. Diphthera orion, Esp. 



Limenitis sibylla, L. Acosmetia caliginosa, Hiibn. 



Tkecla pruni, L. Dianthcecia irregularis, Hiibn. 



Polyommatus arion, L. Plusia orichalcea, Fabr. 



Cyclopides paniscus, Fabr. Epione vespertaria, L. 



Hesperia actaon, Esp. Fidonia conspicuata, SchifT. 

 Trochilium scoliaforme, Hiibn. Scoria dealbata, L. 



Zygcena meliloti, Esp. Cidaria reticulata, Fabr. 



Z. exulans, Hoch. Lithostege griseata, SchifT. 



Nola strigula, SchifT. Agrotera nemoralis, Scop. 



A r . centonalis, Hiibn. Pterophorus rhododactylus, SchifT. 



In these 32 species it will be seen that no fewer than 11 of our butterflies 

 are considered as dangerously approaching extinction in these islands. 



In the ' Athenaeum ' of June 19th was a reprint of Mr. Juo. Murray's 

 list of publications as advertised in that magazine of Dec. 30th, 1837. 

 This affords some reminiscence of the zoological publications at the com- 

 mencement of the Jubilee reign. Besides well-known books, such as 

 Mrs. Somerville on the Physical Sciences, and the fifth edition of Ly ell's 

 ' Principles of Geology,' we notice those well-known, though perhaps now 

 little read volumes, ' The Journal of a Naturalist,' and Jesse's ' Gleauings 

 in Natural History.' 



Dr. Carlos Berg, the Director of the Museo Nacional of Buenos 

 Ayres, is on a visit to Europe. We met this^ well-known naturalist in 

 London quite recently, and he informed us that he returns to the Argentine 

 Kepublic next October. The Rev. J. W. Holland, lepidopterist, of Pitts- 

 burgh, Pennsylvania, has also paid a visit to London. He is undoubtedly 

 the possessor of one of the best, if not the best, collection of general 

 Lepidoptera in the United States, which is particularly rich in African species.
