214 THE ENTOMOLOGIST. 



Some amount of conjecture has been formulated by Bergroth 

 in relation to the generic name Ccqyys as here used. In 1907 

 Breddin proposed a new genus Capyella, which Bergroth cor- 

 rectly surmised was only a synonym of Capys, Stal (1865). The 

 name Capys, however, was also used in the same year by Hewit- 

 son for a genus of Lycsenidfe. Bergroth states that Hewitson's 

 name was published a little earlier than Stal's and that, there- 

 fore, Capyella, Bredd., could be used as a new name, but he does 

 not ^ive us any particulars as to the respective dates of publica- 

 tion, though probably he has some information that is neither 

 known in Stockholm or London where these names were founded, 

 and where I have sought— unsuccessfully — to discover exact 

 dates of publication beyond that of the same year. I therefore 

 do not consider that Bergroth at present is quite justified in this 

 alteration, and I do not follow him. 



ON SOME RECENT ATTEMPTS TO CLASSIFY THE 

 COLEOPTEEA IN ACCOEDANCE WITH THEIE

The Adephaga, Phytophaga, and, with some exceptions, the 

 Lamellicornia also possess only one pair of these accessory 

 glands. In the Phytophaga they are often bifurcate and some- 

 times look like two pairs, as, for example, in Priomis (fig. 7). 

 Two or three pairs are usually met with in other groups. Their 

 division into cctadenia and mesadema seems to be purely 

 theoretical and not yet confirmed by a study of their develop- 

 ment ; and I notice that whereas Ganglbauer classes the single 

 pair in each of the three groups mentioned as ectadenia, Berlese, 

 in his admirable work ' Gli Insetti,' describes those of the 

 Lamellicorns and Phytophaga as mesadenia. Dr. Bordas, in 

 adopting the names given by Escherisch, is careful to dissociate 

 himself from any acceptance of the views implied as to the 

 origin of the glands in each particular case. He himself sug- 

 gests that those of the Longicornia would be more correctly 

 described as mesadenia. 



The Malpighian Vessels. — The importance of these in the 

 classification of the Coleoptera depends upon their number and 

 the view we take as to which is the more primitive number. In 

 beetles they are always few in number, either four or six. The 

 Adephaga, Staphylinoidea, and Lamellicornia have only four; 

 the Heteromera, with some exceptions met with in the MeloidaB,
