NEW BRITISH SPECIES, ETC., IN 1870. 21 



proved. Dr. Chapman has also, in the same Magazine 

 (vi, p. 259 et seq.)y described the larva and given an ehibo- 

 rate account of tlie oeconomy of tlie rare Ahdera hifasciata, 

 which lives on Corticium quercimnn, a fungus growing on 

 oak boughs. He has also given (l. c, pp. 103 and 132) an 

 exhaustive life-history, from original observation, of Pla- 

 tijpus cyUndrus; and (Ann. and Mag. of Nat. Hist., Oct. 

 1870) has, by corroborating and extending the late Mr. Stone's 

 observations, further elucidated the oeconomy of Hhipi- 

 phonis, which is indubitably a parasite, and not, as argued 

 by Mr. Muri'ay in the same publication (Nov. 1869), an 

 inquiline. JNIr. Murray appears, however, to have himself 

 abandoned his first views on the subject. Dr. Chapman's 

 paper is illustrated by a carefully executed plate of the larva 

 of Rhijiiphorus, with details. 



Mr. MoncreafF has (Ent. Mo. Mag., vol. vii, p. 81) given 

 some interesting particulars of the oeconomy of the rare 

 3Iecinus coUaris, which he finds in galls on Plantago 

 maritima; M. pyraiiter occurring in those of P. lanceo- 

 lata; he also notes Baridius laticollis as bred in plenty 

 from roots of Shymhrimn officinale. I reared some forty 

 specimens of this beetle fj-om an inch or two of the infested 

 i-oot sent to me by this careful observer, to whose energy we 

 are indebted (besides very many rarities and other species 

 new to our lists) for the discoveiy of a second British species 

 of CathormioceriiSf which has been sent by Mr. Crotch to 

 Dr. Seidlitz for determination, so that we may expect to be 

 able to include it in our next year's list. 1 have given at 

 full length (Ent. Mo. Mag., vol. vii, p. 150) the differences 

 between this insect and C. socius, and have ventured to add 

 some observations on the points supposed to separate Ca- 

 thonniocerus fi'om TrachyphlceiiSj which in my opinion are 

 not generically distinct.
