least in its typical form, l)ut appears to differ from G. tanaceli (whit'h is 

 always black and shining througlioiit) in having the inetathoracic episterna 

 pubescent (instead of glabrous) and th(^ elytra iisiially costatc. This species 

 {G. pomome) is said to live on Centaurca jacca and its allies, and Knautia 

 arvensis, and the Louth insect (which I have not seen) therefore might well 

 belong to it, G. tanaceti being apparently attached to Achillea. The latter 

 has been taken by me in many localities on the Continent — in Norway, 

 Switzerland, N. Italy, Spain, Pyrenees, &c., — but to the best of my recollection 

 I have never seen it on or near Tanacetum. G. tanaceti has been recorded by 

 D\u-y [Ent. News, xiv, p. 146 (1903)] from the United States, but the speci- 

 mens were subsequently found to be i-eferable to G. pomonge, Scop. [cf. Davis, 

 Ent. News, xviii, p. 269 (1907), which seems to have become acclimatized in 

 Ohio and Illinois. The larvte have been found there on Phlox divaricata. The 

 life-history of this insect is fully described by Mr. Davis (oj). cit. pp. 269-275), 

 and he figures the egg, larva, pupa, and imago. According to Knab [Ent. 

 News, xvi, pp. 230-232 (1905)], the larva of Galeruca is cylindrical, rather 

 stout, and supplied with numeroiis large seta-bearing tubercles ; the median 

 tubercles in G. tayiaceti being arranged in regular longitudinal rows, while in 

 G.pomonse the tubercles of this series are irregtilarly arranged. — G. C. Champion,

Note on the habits of an Algerian Cicada (Melampsalta cantans, F.). — During 

 a recent visit to Algeria with my friend the Rev. F. D. Morice, we spent a few 

 days at Batna (June 22nd — 27th), a place not very far from Biskra, but at a 

 considerable elevation (about 32(X) ft.). To reach the mountain slopes from 

 this town we had to drive daily about eight miles across barley fields, alterna- 

 ting with stony tracts covered with thistles and other spiny plants and low 

 bushes. In these localities a large robust Cicada (Melampsalta cantans, P.) 

 was so abundant as to remind one of the migi-atory swarms of a locust. They 

 seemed to be travelling about the wastes, alighting in large niunbers on our 

 clothes and the seats of the carriage, and even on the coachman's whip, as we 

 drove past daily, and so numerous were they that we had to eject them from 

 time to time from the vehicle. There were no trees near, and the insect was 

 seen resting everywhere on the bushes. Their flight was short and heavy, and 

 luilike most Cicadas, they could be captured easily by hand. This habit of a 

 large Cicada was quite new to me, and therefore seems worth recording. — Id. 



Supplementary broods of Lepidoptera in 1911. — The very interesting note by 

 Mr. G. F. Mathew on a second brood of Limenitis sibylla in September {ante, 

 p. 235) has induced me to record the occurrence of supplementary genei-ations 

 of several species of butterflies and moths during the past wonderful summer. 

 On September 15th, I noticed Pararge megsara, in fair numbers and excellent 

 condition, on the cliffs at Milford-on-Sea, Hants. ; perfectly fresh specimens of 

 its congener, P. egeria, being at the same time on the wing in the New Forest. 

 My friend Mr. C. G. Lam)) informs me that /'. megsera was abvindant and in 

 fine condition at I'adstow, Cornwall, during the last week in September. On
