Karl Verhoeff has recently added another 

 number to his series of articles on palsearctic 

 Myriopods.* This part deals with certain points 

 in the morphology, classification and distribu- 

 tion of the Chilopoda. He makes out four 

 pairs of mouth-parts, and five segments in the 

 chilopod head. The systematic part treats of 

 the genera Bothriogaster, Geophilus, Cryptops and 

 Lithobius. 



Probably no one has studied the varieties of 

 a moth so closely as has Mr. J. A. Clark, who, 

 in a recent article on ' Peronea cristata Fabr. 

 and its aberrations,' f has elucidated and 

 named no less than sixty-two forms of this 

 British moth. Twenty-five of these aberra- 

 tions are here described for the first time. 



Monographise Entomologicse, No. II., is to be 

 * A Monograph of the Membracidse ' of the 

 world, by G. W. Buckton. The first part has 

 been issued, is a quarto in size, and contains 

 fifty-six pages and eight colored plates. It is, 

 however, far from a ' monograph ' ; there are 

 descriptions of many species, but there are 

 many other species listed but not described, 

 and often without reference as to where they 

 were described. One of the new species is 

 from New York, The plates are rather crude. 



Every coleopterist should be interested in 

 Mr. H. C. Fall's recent list of Coleoptera from 

 southern California. J Apart from the fact that, 

 next to the New Jersey list, it is the largest 

 local list yet issued, it is of great value because 

 of the notes on habits and variation of the 

 species mentioned. The total number of spe- 

 cies runs up to 2,197, included in 826 genera. 

 The long lists of Malachiidse and Tenebrionidae 

 are especially marvelous to an eastern collector. 

 Eighty -sesven new species are described, and 

 many others indicated, but not fully studied.

Anopheles* have given many interesting obser- 

 vations. The recent parts relate to the pupa 

 and imago, and will be of particular value to 

 those interested in the external anatomy of in- 

 sects. The detailed descriptions of the emer- 

 gence of the fly from the pupa and of the feed- 

 ing habits of the imago are especially interesting. 

 In the description of the thorax the authore have 

 followed Brauer in the nomenclature of parts. 

 They consider that the first thoracic spiracle 

 belongs to the mesothorax and not to the pro- 

 thorax, as several authors have claimed. 



Major Ross has issued his ' First Progress 

 Report of the Campaign against Mosquitoes in 

 Sierra Leone. ' f This crusade was largely in 

 the nature of an experiment to prove that trop- 

 ical towns, notorious for mosquitoes and malaria, 

 could be largely freed from these plagues by the 

 adoption of certain sanitary measures. It is 

 almost needless to say that it was successful. 

 Empty tin cans, buckets and broken bottles 

 were gathered, pools and puddles in streets and 

 back yards were drained, and in a few weeks 

 mosquitoes were rarities in Freetown.

THE GEOLOGICAL SOCIETY OF AMERICA . 



The fourteenth winter meeting of the So- 

 ciety will be held at Rochester, N. Y., begin- 

 ning on Tuesday, December 31, in the Geological 

 lecture room, Sibley Hall, University of Roches- 

 ter. The meeting will be called to order at 10 

 o'clock a. m. by President Charles D. Walcott. 

 The annual address of the retiring president 

 will probably be given Tuesday evening. The 

 Council will hold an informal session on Mon- 

 day night to open and count the ballots for 

 officers and fellows, and will meet in formal 

 session at 9 o'clock Tuesday morning. If the 

 weather is favorable short exciarsions may be 

 planned ; one to see the Niagara strata of the 

 Genesee gorge in the northern part of the city, 

 and another to the Pinnacle moraine in the 

 southern edge of the city. Ward's Natural 

 Science Establishment, which is across the 

 street from the University, will provide a lunch
