elusion that it is a female. The presence of a tooth on the outside of the anterior 

 tii)iffi would itself be quite an anomalous character in a male of a green African 

 Heterorrhina, and the indication, that the abdomen has "a slight oblong-oval impres- 

 sion," seems as little to support Mr. Westwood's opinion, for in all other species the 

 abdomen of the male shows a broad and deep furrow along its middle. 



" It might seem ludicrous for me to discuss the sex of an insect, which I have not 

 seen, and I would certainly have refrained from doing so, if I had not compared in the 

 Royal jNIuseum, at Berlin, a specimen taken in Mosanibique by Dr. Peters, which I 

 suppose to be the male of Mr. Westwood's insect. It agrees well with the figure of 

 the latter, except that it is considerably smaller, that the anterior tibiie are unarmed, 

 the tarsi longer, and the abdomen with a deep excavation in its middle. These are, 

 however, differences, which, in the genus Heterorrhina distinguish the males from the 

 females. 



" If my supposition prove to be correct it will become necessary to bestow another 

 name on Heterorrhina bicostata of Westwood. 



JRemarlis on Mr. Curtis's recent Descriptions and Figures of British Elaterida. 



"The descriptions and figures of some British Elateridw, published by Mr. Curtis 

 in the 'Transactions' of this Society, New Series iii., p. 10, enable me to point out 

 under what names most of these species have been described by continental authors. 



"Ectinus? gagates, Curt., is undoubtedly Ampedus lugens, of Redtenbacher and 

 Germar, as stated already by Mr. Janson in the 'Entomologist's Annual' for 1855, 

 p. 98. 



" N. G. ? punctolineatus, Curt., is perhaps Ampedus scrofa, Germ., though I have 

 never seen a specimen of the latter which attains the size given by Mr. Curtis, and in 

 which the smooth line down the centre of the thorax, mentioned by Mr. Curtis, is well 

 marked. 



" Elaternigrinus, Curt., seems better to agree with Ampedus obsidianus and brunni- 

 cornis, Germ, (which are varieties of the same species as recognised by Germar him- 

 self) than with the true Amp. nigrinus, Payk., Gyll. 



" Aplotarsus maritimus and Cardiophorus formosus, Cin-t., are unknown to me. 

 Should not the latter be regarded as a foreign insect accidentally introduced into 

 England .'* 



" Aplotarsus? cothurnatus, Curt., is in all probability Ampedus subcavinatus, Germ. 



" I take advantage of this opportunity to state that the Lathrobiura cariuatum, -BoW. 

 figured in the ' Entomologist's Annual,' is angusticolle, Er.^' 



Observations on British ElateridcB. 



Mr. Janson also read some observations, by hinjself. on the British Elateridae, 

 alluded to by Dr. Schaum. 



M. Henri Jekel communicated, through Mr. Waterhouse, the following 

 Note on Omias sulcifrons. 



" A very interesting fact for the British Fauna should be the increase of a genus in 

 the family Curculionidae (though adding no new species), if sullicient generic dilfcrences 

 were to be found.
