ENTOMOLOGY. 335 



nests, have been described as new: CryptopJiagw coucolor, by Miirkcl (Germ. 

 Zeitsclir. v, 244, 181), and At. yidtula and dimidiatipennis, by Maniier- 

 heiin. (Bull. Mosc. 184, 46 ; 185, 47.) I can see no difference between the 

 first and At. fttxcipes (Cri/ptoph. id., Gyll.) ; the second, which Maunerheim 

 found on pines also, I take to be a marked variety of At. mesomelas (Derm, 

 id., Herbst.), with the yellow of the shards confined to a small spot near the 

 tip; the third, from the description, I should have taken for A. ptmlla 

 (Ci-yptopli. id., Payk.), which Miirkel has taken iu*Ants' nests also, if Manner- 

 heim could be supposed to have mistaken that species. 



BYKIIHII. lleicheubach (Ann. Soc. Eut. Fr. ii, LIX), has published an 

 observation made by him, in company with Markel, on the economy of 

 Byrrhus, from which it appears that these Beetles are herbivorous. They 

 found B. ornatus in the Saxon Switzerland, upon a rock overgrown with 

 moss, where it was feeding ; its excrement, dissolved in water, showed par- 

 ticles of the leaves of Mnium puuctatum and cuspidatum. Byrrhus varitts 

 also is common on walls incrusted with Barbula rnuralis. 



HETEROCEKID^. Kiesenwetter has made some additions to his Mono- 

 graph of Heterocerus. (Germ. Zeitschr. v, 480.) 



HYDKOPHILII. This family has been investigated by Mulsant among 

 the series of Monographs by which he is illustrating the Coleoptera of 

 France so effectively. (Histoire Nat. des Coleopteres de France, par M. E. 

 Mulsant. Palpicornes, Lyou. 1842.) 



The following is a summary of the contents, which deserve to be studied, 

 both, on account of the more accurate determination of the characters and 

 for the new genera and species characterized in it.
