Hammersmith Marshes, Feb. 25th, 18G3 ; also two specimens given 

 to me by Dr. Power as C. hoguhris, and probably from the same locality ; 

 Sheppey (Walker). 



Five specimens from Slapton Ley {J. H. Keys in coll. Walker) 

 may be a variety of C. sfenialis, but they have the mesosternal lamina 

 a little smaller. 



5. — Cerycon pumilio, sp. n. 



Ovalis, ang-ustus, valde convexus, niger, palpis antennarura basi, pedibus 

 elytroruraque apice testaceis ; elytris sericeo-.>ubopacis, stiiat.s, strii,-, ad apicem 

 prufundis; mesof^terni lamina ^at protuberaute, sat lata, basi ad meta&terni 

 apicem contigua; pedibus gracilibus. Long, capite extenso vix 1| mm. 



This minute insect is only as large as Cercyon pygmaeus ; though 

 closely allied to C. sternalis, I do not think it will prove to be a variety 

 of that ; it is only one -fourth the bulk thereof, is of a slightly different 

 shape, and the mesosternal lamina is not quite so broad.

ON A NEW SPECIES OF CAMPODEA (C DEVONIENSIS, sp. n.) 

 FEOM SOUTH DEVON. 



BY EICHAED S. BAG:N^ALL, F.L.S. 



Amongst a small collection of Campodea I had recently the oppor- 

 tunity of making in the neighbourhood of Torquay is a smallish species 

 which cannot be identified with any described form. It belongs to the 

 third section of the genus, which is distinguished by the absence of 

 the macrochaetae at the hind angles of both the meso- and metanotum. 

 This section may be further subdivided, the one group containing those 

 wherein both pairs of the anterior (submedian and sublateral) macro- 

 chaetae are present in the mesonotum and the submedian anterior pair 

 present in the mesonotum, and the other group containing those in which 

 the submedian anterior pair of macrochaetae is absent in both the meso- 

 and metanotum. 



In this second group Silvestri places two species^ C. emery i, which 

 retains the sublateral anterior macrochaetae in the mesonotum, and 

 C. ribauti, wherein both anterior pairs in the mesonotum are lost. 



Campodea devoniensis, sp. n. 



Length 2-5-3'0 mm. Belonging to the second subdivision of the third 

 section ut" the jieuua and having the notal maciochaetae numbered as in
