IN SEARCH OF ENTOMOLOGISTS. 125 



bably have remained lost to science, but for the accidental 

 discovery. So true it is that not merely the Micro-Lepi- 

 doptera, but also the Micro-Lepidoptemls, leben oft sehr ver- 

 borgen! (often live quite concealed). 



Of Herr Grabow's observations the following were the most 

 important. The larva of Harpella bract eella feeds in spring 

 in decayed wood, it having been found under the bark of a 

 branch of a mulberry tree, and also under the bark of dead 

 branches of acacia : the larva of Harpella proboscidellu, 

 which has long been known as a wood-feeder, feeds in oak and 

 willow, and spins its u frass" together very similarly to our 

 Dasycera sulpkurella, it bores through the wood in all direc- 

 tions ; Laverna atra (the black variety) feeds in apple shoots 

 as already mentioned (ante, p. 56) ; Gelechia Populella, the 

 variety Blattariella, would appear to be a distinct species, 

 it is found in early spring in the fallen birch leaves, in 

 those which are rolled up ; the head and second segment are 

 pale brown, whereas in the ordinary larvae of Populella :, 

 which feed on poplars in May and June, the head and 

 second segment are black : the larva of Gelechia pinguinella 

 feeds under the moss, on the trunks of poplar trees in May; 

 the larva of Gelechia alacella feeds in June on the lichens on 

 the trunks of orchard trees (see ante, p. 51); the larva of 

 Acrolepia as.sectella feeds in the leaves or stems of the leek, 

 in September; and the larva of Asyckna ceratella (as already 

 mentioned, see ante, p. 57) forms a gall on the flower-buds 

 of Polygonum aciculare, which has the appearance of a 

 small pod, and in it the larva feeds in the autumn, changing 

 to pupa the following: spring. 



My visit to Herr Grabow was not of long duration, as I 

 had an engagement that afternoon at Potsdam, but as my 

 visit to General Direktor Lenne was not an Entomological 

 one, I say nothing further of it here than that it was a very 

 pleasant one, and I hope some day to repeat it and renew 

 my acquaintance with the two amusing parrots.
