 base. 



4. AcTOCHARis, g. n., Sharp, Ent. Montlily Mag., vol. vi, 



p. 279 (characterized, and maxilla and labium 



figured). 

 The obsolete eyes, four-jointed anterior and intermediate 

 and five-jointed posterior tarsi, two-jointed labial palpi, bifid 

 ligula, and swollen third and subulate apical joint of its 

 maxillary palpi, give an anomalous character to the species 

 upon which this genus is founded. Dr. Sharp, however, 

 thinks there is no doubt that it must be placed among the 

 true AleocharidcB,\\\ou^\\ in the elongate lobes of its maxillae 

 it clearly approaches Myllcena, — and, in its palpi. Gyro- 

 phcena. He thinks it best placed near Sili/sa, 



5. AcTOCHARis Readingii, Sharp, /. c, 1 May, 1870, 



(described). 

 This insect, originally found (I believe beneath high-water 

 mark) by Mr. Reading, and subsequently by Mr. Wollaston, 

 near Plymouth, has for many years been recognized, but 

 without a name, in the chief British collections. Now that 

 it has in these latter days been described by a British Ento- 

 mologist (who has adopted the M.S. name originally pro- 

 posed for it by Mr. Janson, by whom it was originally 

 detected), M. Fauvel in Deyrolle's *^ Petites nouvelles Ento- 

 mologiques " has claimed priority for the name, marina, 

 under which he states that he has described it in 1869. I 

 have been unable, however, to find any such description by 

 him during that year. 



6. OcALEA latipennis, Sharp, I. c, p. 280 (described). 

 Allied to O. castanea, Er. ; but rather larger, darker in
