pupse of Heterocerous Lepidoptera, observed that the most product- 

 ive trees were the ehn, oak, ash, poplars, beech aud willow ; by 

 digging at the roots, he had procured from Elm, — SmerintJms tilice, 

 Petasia cassinea, Tceniocampa populeti, Cosmia diffinis, Xylina semi- 

 hrunnea, &c. 



Oak, — Notodonta trepida, N. Chaonia, N. dodoncca, Geometra 

 papilionaria, &c. 



Ash, — Pcecilocampa populi, Acronycta ligustri, Geometra ilhis- 

 traria, &c. He stated that the most productive localities were scat- 

 tered timber trees in meadows and parks, more especially in the 

 neighbourhood of farms, villages and towns, the borders of woods, and 

 under the thick moss on roots of trees, in the open places. On the 

 general habits of pupse he observed, that they were always found 

 nearly close to the surface, and within 2 or 3 inches of the trunk, 

 often concealed in the roots of clumps of grass. 



Mr. Waterhouse communicated to the Meeting the results of his 

 examination of the British species of Hydrochus and Ochthebius. 

 He stated that his object had been, first, to ascertain what species 

 existed in England ; and secondly, by what names they were known 

 both at home and abroad. 



Of the first-mentioned genus little need be said ; he found three 

 species only in our collections, viz. : — 



1 . Hydrochus brevis, of German, French and English authors. 



2. elongatus, also of continental and English authors. 



3. anyustatus, of Miiller, Germar, Mulsant, Stephens, 



&c., very commonly known by the name cretmtus, having been 

 erroneously regarded as the Elophorus crenatus of Fabricius ; that 

 insect, however, proves to be (according to Erichson) the Latridius 

 porcatus. 



Of the genus Ochthebius Mr. Waterhouse was acquainted with ten 

 British species, viz. : — 



1 . Ochthebius marinus, of continental authors, and of Stephens. 



2. tBneus, Waterh., Steph. 



o / margipallens (Latreille), Mulsant. 



\pusillus, Waterh., Steph. 



4. pygmceiis, Stephens, and continental authors. 



5. bicolon, Stephens, and continental authors. 



6. rufimarginatus, Steph. 



7. exaratus, Mulsant. 



CtEratus, Stephens. 



8. <( nanus, Stephens (a dark variety).
