tive of difference of latitude ; and that where we find a particular species, we may 

 generally look for those with which it is associated in other districts where it occurs.

New Locality for Eudorea lineola, and Note on the Larvae. — On the 27th of last 

 June I took several larvae of the above rare Eudorea feeding under the yellow canker- 

 moss on old blackthorns, growing on the sea-shore, on the south side of the Hill of 

 Howth, a description of which may not be uninteresting to the readers of the ' Zoolo- 

 gist,' as the insect has hitherto been taken only near Doncaster, and that in the imago 

 state. Length nearly 1 inch : ground-colour a pale dingy green, with three rows of 

 olive-brown or brownish black square-shaped spots, those along the back being the 

 largest ; the intensity of the colours varies greatly, some being much darker than 

 others. The larva? were full fed when I took them, as they were all in pupae by the 

 beginning of July, and the first insects came out on the 16th of the same month. —

Food and Transformation of the Larva of Elachista locupletella. — T am very glad 

 to be able to give my brother entomologists an opportunity of rearing for themselves 

 one of the most beautiful of our Micro-Lepidoptera. The larva of Elachista locuple- 

 tella feeds on Epilobium alsinifolium, and perhaps, as has beeu suggested to me, may 

 also feed on any plants of that order. This plant I find pretty abundant here at the 

 bottoms of walls in marshy situations, and I have not unfrequently found as many as 

 three or four larvae feeding upon one plant, but never more. They are easily detected 

 from being miners ; the leaf becomes discoloured, and thus the habitation of the larva 

 is at once made known. I have also had two mining the same leaf, but this I set 

 down as a matter of necessity, from my breeding-cages being small, and the plants few 

 in number in each. The larvae are to be found in May, in a tolerably advanced state. 

 They are of a dirty greenish browu colour, and when full grown are about three eighths 

 of an inch in length. In my breeding-cages I had the insect in all its stages of larva, 

 pupa, and imago at the same time. When about to undergo its transformation, which 

 is about the first week in June, the larva quits the interior of the leaf, and either crawls 

 away to the bud of some plant near at hand, which it draws together with beautiful 

 white silken threads, or it rolls the edge of one of the leaves of the plant on which it 

 has fed half round, and then constructs a snow-white covering, in which it changes to 

 a brown pupa. The perfect insect appears in from fourteen to eighteen days after the 

 transformation. — John Scott ; London Works, Renfrew, December 7, 1852. 



Economy of Crabro cetratus. — In February, 1851, observing several excavated 

 brambles in a hedge which had been cut over, I felt curious to know the excavator, 

 and carried home a few of them. On cutting open some of the stems, I found they 

 were tenanted by three or four orange-coloured larvae or pupae ; some of the larvae were 

 quite small, others apparently full grown ; and the pupae varied in colour from orange 

 to jet black, many having the head and thorax black, with the abdomen orange. The 

 nidi had been provisioned with a green Aphis. On the 16th of July following the 

 perfect insects began to appear, and proved to be the Crabro cetratus of Shuckard. 

 Some half-dozen ichneumons, with a shortish ovipositor, were developed about a fort- 

 night before the Crabros. When I pinned the latter, they emitted a powerful per- 

 fume, somewhat resembling that of roses. A day or two previously to the appearance 

 of the above, I met with an excavated raspberry-stem in our garden, and captured the 

 female of the same species while in the act of fabricating her cells: she had excavated 

 to the depth of nine inches, had formed three cells, and was busy with the fourth.
