whole year's history comes to this : — egg laid about middle of June ; larva hatched 

 within a week, fall-fed, and fixed motionless about the end of July, bo continuing ten 

 months till the beginning of next June ; the pupa state then lasting some ten days 

 or so, and the imago (apparently) living but a short time to perpetuate the species. 

 The long continuance in the larva state, after being full-fed, seems very remarkable. 

 — J. Hellins, Exeter : June lUh, 1873. 



Erroneous food-plant assigned to a larva. — In Yol. x of the ISI'atural History of 

 the Tineina, by a curious blunder, at p. 48 Gelechia morosa is said to feed on Ly- 

 thrum salicaria ; whereas Miihlig says distinctly in the Stett. ent. Zeit., 1864 (not 

 1862 as quoted N. H. T., Vol. x, p. 14, No. 43) " I found the larva at the beginning 

 " of May in the fresh heart-shoots of LysimacMa vulgaris." 



Hence, at p. 48, the name of Gelechia morosa should be removed from the in- 

 sects feeding on Lythrum, and, at p. 50, under the Nat. Order Primulacece, there 

 should be introduced after 



Primula farinosa 45 Farinosce. 



Lysimachia vulgaris ... 43 Morosa. 



I have been led to this discovery from tlie fact of Mr. Barrett finding a lai-va in 

 the shoots oi Lysimachia, and writing to ask me what it could be. — H. T. Staiston, 

 Mountsfield, Lewisham, S.E. : June 'ith, 1873.

This useful little manual is based on a plan to which we have nothing altogether 

 analogous in works treating on the Butterflies of Britain. There are no detailed 

 descriptions of the species, but this is attempted to be supplied by long dichotomous 

 tables of those under each genus, with copious locality notes, and memoranda of the 

 principal varieties and aberrations ; and accompanied by a map illustrating the 

 faunistic divisions of the kingdom. The work cannot, we think, fail to be of much 

 service to yoimg Belgian entomologists, and those of our own coinitry will probably 

 find it useful, for there is considerable identity of the Butterfly-faunas of the two 

 kingdoms. Ninety-nine species are enumerated as found in Belgium. Not the least 

 valuable portion is a copious introduction by M. de Borre (the indefatigable Secretary 

 of the Belgian Entomological Society) on the geographical and geological features of 

 the kingdom, which we think will do much towards expanding the ideas of his 

 young readers, and prevent them from cherishing those narrow views that must be 

 engendered by confining their attention solely to the fauna of a country like Belgium, 

 which has political but no natural limits. He vrinds up by an apologue which we 

 translate. " One day a foreigner, interested in the science of languages, and very 

 " ignorant of those spoken in Belgium, arrived there, and, after the manner of 

 " voyagers in the South Seas, set to work to draw up a little vocabulary of Belgian. 

 " After having successively visited Ostend, Bruges, Grhent, Antwerp, and Brussels, 

 " and collected in each of those towns a hundred flemish words, he was in Tournay, 

 " where he obtained a hundred words of tlie dialect of that place ; afterwards the 

 " tdwns of Mons, Namur, and Lie'ge each furnished him with a hundred words of
