to the Meeting : the chief feature worthy of notice was the dominant influence 

 of the male parent upon the hybrid offspring, the larva throughout its career 

 and the cocoon more closely resembling B. Peniii than A. Yamamai. The 

 dominant influence of the male had also been observed by Mr. Brady, of Sydney, 

 in his experiments on B. mori (see Report of Acclimatization Soc. of Sydney 

 for 1868). Another point worthy of observation was that, even at so late a 

 period of the year, the larva fed well on the evergreen oak, which, according to 

 Dr. Wallace's experience, was largely eaten by all the oak-feediug species. 



Paper read. 



The following paper was read : — " Descriptions of twelve new exotic species 

 of the Coleopterous family Pselaphidae ; " by Prof. Westwood. 



Eight new genera were founded, under the names Goniastes, Rhytus, 

 Curculionellus (three species), Sathytes, Pselaphodes, Sintectes, Phalepsus and 

 Ryxabis; and two species were added to the genus Bryaxis.

 Mr. Dunning exhibited a locust captured near Thirsk, Yorkshire, in the 

 autumn of 1849 : the prothorax was flat and constricted in front, and notwith- 

 standing the contention of Prof. Westwood (S. S. 2144) he thought this was 

 the true Locusta migratoria of Linue. The appeal to tradition did not tell 

 entirely on one side : Fabricius when he described ciuerascens was acquainted 

 with migratoria, and it was clear from his description that cinerascens was the 

 form with the arched prothorax ; consequently migratoria, from which Fabricius 

 separated cinerascens, was according to his belief the form with the flat 

 prothorax. But further, from the time of Fabricius to the present, cinerascens 

 had always been regarded as a doubtful species, the ma.jority of authors having 

 treated it as only a variety of migratoria; the entomologists from whose 

 collections the Oxford specimens were derived might have been of this opinion ; 

 at all events until it was shown that they recognized the existence of the two as
