anatomical and generic characters ; and he increases our lists 

 by one new species and one Stephensian revival, both at the 

 expense of the insect usually known here as Hydrohius 

 limhatus, but which is now to be recognized as Anacwna 

 globulus, Payk. 



Dr. Shaip (Z. c, p. 230) has also published some interest- 

 ing notes on the identity of certain species of Somalota 

 taken by Mr. Crotch in the Asturias with our recorded 

 Britisli species; and consideis that the number of European 

 species in that genus will be found to be much smaller than 

 would be supposed from the large number in this country. 

 Mr. Champion, /. c, p. 257, has also contributed a list of 

 localities for upwards of eighty British species oi' HoJiialota. 



Mr. Ciotch has communicated to the Entomological 

 Society a laborious paper on " The Genera of Coleoptera 

 studied chronologically," and has in Newman's " Entomo- 

 logist," No. 73, given short characters for and observations 

 upon the British species of Triplax, Engis and Rhynclutes. 

 In the latter genus he adopts jnirpiireus, Linn. (1758) for 

 cequatus, Linn. (1767), Desb. des Loges ; interpunctatus, 

 Steph., for alliarice, Schon. ; and planirodris, Fab., for

 rarer nanus, Payk., found on birches, may be known fi'om 

 it, — viz., the considerably smaller size, obsolete punctuation 

 of the head and less regular punctuation of the thorax and 

 elytra, aud much shorter rostrum, which is angular at the 

 base. 



Dr. Algernon Chapman (Ent. Mo. Mag., vol. vi, p. 230) 

 has published some additional notes on the parasitism of 

 Aphodius porcus upon Geotrupes stercorarius; — M. Reiche 

 (in Ann. Soc. Ent. Fr., 4me ser., ix, Bull., p. xxii) having 

 stated his opinion that further obsei'vations on the point 

 were necessary before that parasitism could be accepted as
