state six weeks they carae forth cripples, with the exception 

 of two, which expanded their wings witli difficnUy, then 

 retired to a corner of the breeding-cage, and expired in the 

 course of three or four da3's. The first brood remained in 

 pupa from ten to fourteen days. — IV. West ; 6, Green Lane,

Acidalia inierjectaria and Cochtjlis musselduina. — It fell 

 to my lot last sjjring to make a long stay in Germany, and 

 whilst at Aix-la-Chapelle I enjoyed the privilege of looking 

 over the magnificent collections of European insects and 

 plants formed by Herr Kaltenbach, well known to English 

 entomologists as the discoverer of the larva of the genus 

 Micropteryx. The Lepidoptera had been arranged under 

 the eye of Dr. Staudinger, and were therefore well calculated 

 to be of service in the identification of species, in order to 

 ascertain their right names. In going through tlie genus 

 Acidalia I at once remarked that the species w^hich we have 

 in our cabinets under the name of" osseavia" is the dilutaria 

 of Hlibner and the interjectaria of Boisduval. The true 

 ossearia (supposing Dr. Staudinger to be correct in his 

 opinion) I have not yet seen in any cabinet in this country : 

 it is a larger insect than interjectaria, the wings are longer 

 and not so rounded, and the colour of the costa is unques- 

 tionably rufous, or, as M. Guenee describes it, the colour of 

 our penny poslage-stamp. I should be glad to learn from 

 any of your correspondents whether they have taken the true 

 ossearia. Among the Tortrices in Herr KaUenbach's col- 

 lection I noticed a fine series of Cochylis mussehliana, a 

 species of which 1 believe very few examples have occurred 

 in this country, and the larva of which feeds on the stems of 

 Alisma plantago. With his usual kindness Herr Keltenbach 

 presented me with a pair of mussehliana ; but on reaching 

 home, and comparing them with a single specimen in my 

 possession, tal^en some years ago in Devonshire and named 

 by Mr. Doubleday, 1 find no resemblance whatever. On the 

 other hand the continental specimens of mussehliana appear 

 to be identical with the " griseana" vel "udana" of our 

 cabinets I Can Mr. Doubleday clear up this little difficulty?

 to inform me if the larva of E. versicolor will feed on any
