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

 tibiae 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 



| Koyal Museum, at Berlin, a specimen taken in Mosambique 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 tibia? 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 proves to be correct it will become necessary to bestow another 

 name to Heterorrhina bicostata of Westvvood. 



Remarks on Mr. Curtis's recent Descriptions and Figures of British Elateridce. 

 "The descriptions and figures of some British Elaterida, 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 jseen 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. 



" Elater nigrinus, 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, Curt., 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 subcarinatus, Germ. 



" I take advantage of this opportunity to state that the Lathrobium carinatum, Bold. 

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



Observations on British Elateridce. 



Mr. Janson also read some observations, by himself, 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 sufficient generic differences 

 were to be found.
