five generations in a year. A new Catocala (Lep.) and a new genus of 

 Cerambi/ciclae, Mef/ocheitiiia are introduced in the same number. 



The Anil. Soc. ent. Bel//., July, 1919, contains an interesting article 

 on " Instinct and Intelligence " as exhibited by the Aiiimojihila (Hym.), 

 illustrated by a series of " experiences." 



An extract from the At. Snc. Ital. Sci. Nat., vol. Iviii., has been sent 

 by Count Turati, containmg a List of the Lepidoptera occurring in the 

 sub-Appennine region of Modeua at the elevation of about 1,000 

 metres from July 12th to September 27th, 1918, with notes on the 

 various species and a description of three new species of Micro- 

 lepidoptera with figures. Some 65 species of butterflies were observed 

 and opportunity was taken to name still another form of Famasdus 

 imieiiwsijne viz. constantinii, a form of Erebia medusa viz. Jii/perapennina, 

 a form of E. stygne viz. constantinii, still another form of Melanargia 

 galathea viz. apicalis, a form of Cyaniris sewiargns viz. semisehrus, a 

 form of Lycaena alcon viz. italica, and several new forms among the 

 Heterocera. Unfortunately the nomenclature troubles us, e.g., the use 

 of idas, L., a form of tlietis called corydon, alexis. Pad. used for cyllanis, 

 a cydippe form of niobe, the non-informative polynominal names, &c. 

 The notes are most useful and suggestive to one who is interested in- 

 the Italian fauna, on account of the great knowledge of the literature 

 of what has been done by all previous workers. 



The Bull. Soc. ent. Belg., I (iv), p. 60, contains notes on the 

 " Dytiscidae and Gyrinidae of the neighbourhood of Alost," found from 

 1915-19, by A. Ball; "Biological Notes on Odonata, etc.," by 

 J. Lestage, etc. 



An Investigation of the Louse Problem (Research Publications of the 

 University of Minnesota), by W. Moore, B.A., and A. D. Hirschfelder, 

 M.D., is an important treatise dealing with (1) Methods of rearing lice 

 and notes on their biology. (2) Pathological effects of the bite of the 

 clothes louse. (3) Methods of control of the clothes louse. (4) 

 Methods of louse destruction by pediculicides. A large mass of 

 statistics is taken into account and a useful Bibliography is added. 



The London County Council have published an 8-paged pamphlet 

 written by A. Bacot, F.E.S., Entomologist to the Lister Institute, 

 entitled Danger of Disease througJi Lice and, How to avoid it. ' 



The " Popular and Practical Entomology" columns of the Can. 

 Ent. always contain matter which is of great educational value. The 

 subject in the June-July number is " The Variation of Insects " by 

 T. I). A. Cockerell, Colorado. The writer commences his article by a 

 well deserved recognition of our late Editor. He says " Nearly thirty 

 years ago English entomologists began to take a new interest in the 

 variation of Lepidoptera, and in the interval since that time, 

 principally owing to the activities of J. W. Tutt, a very large amount 

 of detailed information has accumulated. Tutt's British Noctuae and 

 their Varieties, in four volumes (1891-2), deserves to rank as a classic, 

 although at the time of its publication it was received by many with 

 something less than enthusiasm. More recently the great monograph, 

 of the British Lepidoptera, left unfinished owing to Tutt's untimely 

 death, covered the subject of variation in an exhaustive manner, 

 including all phases of the species treated, whether British or foreign. 

 In its exhaustive character, this work runs parallel with Taylor's 

 Monograph of the Land and, Freshwater Mollusca of the British Islands,
