unidentified by liim. Four subgenera are recognized, one of which, Mito- 

 mermus Duv., is placed as a synonym of Trachyphloeus Germ, in the European 

 Cataloo-ue of 1906, our C. socius Boh. and C. maritimus Rye belonging to 

 Cnthonniocerus s. str. The 61 text-figures, all drawn under the camera lucida, 

 X 34, show the form of the anterior tibiae in each of the subgenera, and the 

 head, antennae, etc., of most of the species. These apterous epigaeous weevils 

 have, as might be expected, a very limited distribution, though some of the 

 allied Trachyphloei, like scabriculus L., may sometimes be found in quantity in 

 unexpected places. No additional localities are given for C. socius (the type 

 of which was from England, from Walton's collection), beyond the Isle of 

 Wight and the Sierra Nevada in Spain, the C. socius of Seidlitz, Bedel, and 

 Chevrolat apparently belonging to other species. The variety of C. maritimus 

 from Brittany is named armoficus. Another British representative of this 

 genus, from the Lizard, Cornwall, sent me some time ago by Mr. Keys for 

 determination, not seen by M. Escalera, must remain unidentified till an 

 example in better condition is obtained. Numerous new species and varieties 

 are described and figured in the " Revision," one of which, from the Alto 

 Atlas, is called C. tizi-n'testi (sic), a specific name to which one might take 

 exception. The material captured by Commander Walker and myself in 

 Spain has been examined by the author and is included in his enumera- 

 tion. The geographical distribution of C. socius remains inexplicable. — G. C,

Cerycon sternalis Sharp at Oxford. — The publication of Dr. Sharp's paper 

 " On some species hitherto assigned to the genus Cercyoii " (Eut. Mo. Mag. 

 1918, pp. 274-277) has induced me to send him for examination the material 

 collected by myself in this district, more especially as I was responsible for the 

 record C. lugtibris from Oxford. He has kindly named them and says: — " You 

 have separated your CerycorSs correctly, but your granarius is luguhris, and 

 your lugubris are stei-tialis" meaning I had separated them into species, but 

 applied the names wrongly. On August 12th, 1908, 1 took about 18 specimens 

 of what proves to be C. sternalis, from wet moss at Yaruton, Oxon. On 

 January 26tli, 1908, at Yaruton also, I captured a specimen which turns out 

 to be C lugubris. I have C. lugubris, var. inter^nijctus, teste Dr. Sharp, from 

 Water Eaton, Oxon, taken on July 29th, 1907, and one example from Weston- 

 on-the-Green, Oxon, April 18th, 1909. The long series I called C. lugubris and 

 the three examples C. granarius. Curiously enough, I have only one example 

 of C. minutus from Oxford, this I named correctly. — J. Collins, 74 Islip

Note on Nomada roberjeotiana Pajiz. — The species figured by Panzer is, I 

 think, clearly distinct from that which stands under this name in our lists and 

 collections. The male of the true roberjeotiana has a single bright flavous 

 transverse yellow spot on the scutellum, much like that of rvfpes F. (solida- 

 ginis Panz.), the $ has a bright yellow prothoracic band like the male, and 

 the hind tibiae with a definite, wide, black ring. In both sexes the hind 

 femora are pale to a far greater extent than in the British species. If Panzer's 

 figures are correct in this respect, the antennae are also decidedly shorter and 

 thicker. Continental writers give Andrena afzeliella,fuseipes, and xaJithura as
