The varieties are ' Zoological works published under Government 

 patronage;' 'The Entomologist: conducted by Edward Newman, 

 F.L.S. ;' and 'Investigation of Myriapoda.' In the last we are in- 

 formed that an elaborate memoir on this group by Mr. Newport may 

 shortly be expected.

Art. LX. — Analytical Notice of the A9th Numher of the ' Annals 

 and Magazine of Natural History^ dated October, 1841. Lon- 

 don : Richard and John E. Taylor, Red Lion Court. 



Art. XV. — Description of a hitherto undescribed character distinctive of the Sexes 

 in certain Lucanidae. By J. O. Westwood, F.L.S. 



The character to which Mr. Westwood alludes is a corneous hook 

 at the extremity of the mando or internal lobe of the maxillae, pointed 

 out to him by Dr. Burmeister, and existing in the genera Pholidotus 

 and Lamprima in the females only ; in Nigidius and Ceratognathus 

 both sexes possess this hook; but in Ceruchus, Platycerus, Cera- 

 tognathus,* Syndesus and Rhyssonotus, it has not been detected in 

 either sex ; and the females of Chiasognathus and Sphenognathus 

 have also been found to be destitute of the hook. 



Mr. Westwood has commenced in the same number a paper enti- 

 tled ' Tnsectorum Novorum Centuria.^ The first portion, or ' Decadis 

 primae Coleopterorum Synopsis,' records ten new Coleoptera, the au- 

 thor giving, after the plan of my Entomological Notes, a character in 

 Latin, the size, the habitat and the collection in which the specimen 

 exists. As the author states that figures and detailed descriptions of 

 these insects are prepared and will be published hereafter, I shall de- 

 fer giving an abstract of the characters until the appearance of the 

 promised republication.

* There must be some mistake in this; I therefore quote the passages verbatim. — 

 " In Nigidius and Ceratognathus, W., the males of which are at once recognisable by 

 the increased size of the mandibles, I found the maxillae in this sex furnished with 

 the hook as well as in the females." — p. 122. * * " Xhe genera in which I 



have found neither sex furnished with the hook are Ceruchus, Platycerus, Ceratognathus, 

 W., Syndesus and Rhyssonotus.^' — p. 123.
