plants it attacks, and is much dreaded by the gardeners of Vienna 

 and Berlin. It has not yet been found in this country, but as, accord- 

 ing to Fischer, it has occurred on the plum-tree, and indeed Fischer 

 suspects it also feeds on sloe, the chances of our finding it here are 

 very considerable. 



Pr units domestica. Plum. 



Speyer enumerates the following species as feeding on this plant: — 

 Papilio Podalirius, Pieris Crataegi, Thecla Pruni, T. Betulae, Trochi- 

 lium culiciforme, Liparis dispar, Porthesia chrysorrhaea, P. auriflua, 

 Orgyia gonostigma, O. antiqua, Eriogaster lanestris, Clisiocampa 

 neustria, Gastropacha Pruni, Acronycta trideus, A. Psi, A. Rumicis, 

 Orthosia instabilis, O. stabilis, O. munda, Amphipyra pyramidea, Mi- 

 selia culta, M. Oxyacanthae, Xylina rhizolitha, X. petrificata, Catocala 

 paranympha, Ennomos alniaria, E. lunaria, E. illunaria, E. illustraria, 

 Ourapteryx sambucaria, Rumia crataegata, Angerona prunaria, 

 Chlorochroma vemaria, Hibernia leucophaearia, H. defoliaria, Boar- 

 mia rhomboidaria, Tephrosia crepuscularia, Biston betularia, B. hir- 

 taria, B. prodromaria, Coremia fluctuata, Eupithecia rectangulata, 

 Tortrix diversana, T. crataegana, Penthina prunina, P. variegana, 

 Carpocapsa Waeberiana, C. pomonana, Exapate gelatella, Cerostoma 

 scabrella, C. asperella, Swammerdamia pyrella, Coleophora anatipen- 

 nella ; he also mentions Pterophorus pentadactylus, which we know 

 feeds only on Convolvulus ; and this 'capital error shows with what 

 caution all the preceding statements must be received. In the fore- 

 going list the species not yet detected in this country are designated 

 by Italics. 



The most important plum-feeder that we know is Opadia fune- 

 brana, the larva of which feeds in the inside of the fruit of the plum. 

 All eaters of plum-pie must have observed that some plums have the 

 stone embedded in a layer of little brown grains, which are in fact the 

 " frass " of this larva, though when we see this " frass " in a boiled 

 state and swimming in juice, unless we are entomological enough to 

 know what it is, it eats very well. 



" What the eye don't see, the heart don't feel." 



Strange that an insect so common that we see it by dozens in our 

 plates is so seldom met with by entomologists that it is to be found in 

 very few collections ! — but the habit of the perfect insect is very 

 retired, and when sitting on the stem of the plum-tree, from its uni- 

 form dingy colour, it is not very easily recognized.
