Insects, 4905 



Occurrence of Lithocolletis Bremiella in Britain. — At the October meeting of the 

 Entomological Society Mr. Stainton exhibited leaves of Vicia Sepium mined by the larvae 

 of Lithocolletis Bremiella, an iusect entirely new to Britain, since which Mr. Douglas 

 informs me he has bred thirty or more of the same new species from similar larvae. — 

 Edward Newman. 



Note on Tinea granella. — This species must be double-brooded, as I observed, on 

 the 13th inst., many specimens settled on the walls of the granaries in Clink Street, 

 Southwark, which, from their fine appearance, could not long have quitted the pupa 

 state. There were also crawling about on the walls numbers of small larva?, of a yel- 

 lowish white colour with brown heads, which were most probably referrible to this 

 species. I likewise noticed specimens of Calandra granaria. — C.Miller ; 17, Silurian 

 Terrace, Brooke Road, Dalston, October 15, 1855. 



Note on Coli/mbetes dispar of Bold. — My Coleopterist readers will recollect that in 

 the Appendix to the 'Zoologist' for 1849 (Zool. App. xxiv.) Mr. Bold described a 

 Colymbetes under the name of dispar : the description was particularly minute, and 

 the author appeared to have taken great pains to ascertain whether any previous 

 description existed. I was unable to obtain a sight of this insect until February of the 

 present year, when Mr. Janson very obligingly allowed me to see a pair presented to 

 him by the discoverer, and it appeared to me that they closely resembled a species I 

 have long known under the name of uliginosus, and Mr, Janson, in the ' Entomo- 

 logist's Annual,' had previously expressed an opinion that it was probably a variety of 

 that species. Within the last month Mr. Bold has most kindly and liberally sent me 

 a series of both sexes, and I have thus been enabled to give the species a careful 

 examination and comparison, the result of which is that I can discover no difference 

 whatever between dispar of Bold and uliginosus of Paykull. On communicating this 

 opinion to Mr. Bold, that indefatigable entomologist called my attention to the great 

 dissimilarity of the sexes, a character which induced him originally to name the 

 species dispar. On again referring to my sexes of uliginosus, I found the similarity 

 complete in this respect also ; and I may here observe that the discrepancy which 

 frequently obtains between the sexes of the Hydradephaga does not appear to have 

 been sufficiently noticed : in Dytiscus and Acilius the elytra are sulcated in the female, 

 and this character appears to be represented, in many species of Colymbetes and 

 Hydroporus, by a rougher surface, causing a dull appearance, which contrasts forcibly 

 with the extreme glabrous and shining surface of the elytra in the males. On subse- 

 quently communicating with Dr. Power and the Rev. Hamlet Clark, I was delighted 

 to find that those careful entomologists had, independently of myself and of each other, 

 arrived at the same conclusion as to the identity of dispar and uliginosus. Another 

 question, however, seems to arise, and the result will I believe be the retention of 

 Mr. Bold's name. It is a well-known rule that two species in one genus cannot bear 

 the same name: now, at the time the name of Colymbetes uliginosus was applied to 

 the insect under consideration, there already existed a Colymbetes uliginosus, that 

 specific name having been originally applied by Linnaeus, as proved both by description 

 and specimen, to the subsequently named fuliginosus of Fabricius, Gyllenhal and 

 Aube. — Edward Newman. 



Occurrence of Scolytus destructor in Lancashire. — Mr. Bold's communication 

 respecting this little "destructive'' in the October number of the 'Zoologist' (Zool. 

 4873), reminds me of its occurrence, on the wing, at Stretford in this district in 

 August last ; a boat was being laden with recently-felled timber close by, out of which,
