THE CANADIAN ENTOMOLOGIST. 125 



had dug out collected between the props. When outside it opened the 

 props and dropped the bits of wood. This operation was repeated until 

 the hole was large enough, when the caterpillar entered for the last time, 

 leaving its black hairs at the entrance. 



The last one made but one opening to the hole, and did not, as far as 

 we could see, spin a door across. Three of the others made openings at 

 each end, and closed both with silk and hairs. The first one was kept in 

 a paste-board box, and, no wood being given to it, gnawed a hole through 

 the box. When we covered this hole, the caterpillar spun against the 

 side of the box a thin cocoon of silk mixed with the bits of paste-board 

 gnawed from the box. None of them would go into the earth when it 

 was provided for them. The pupa of the second one was kept for two 

 years, but showed no sign of life, and was then thrown away. 



We should be very glad of any information about this larva that any 

 readers of the Entomologist can give. 



COLEOPHORA LARICELLA Hb. VERY INJURIOUS TO LARIX 

 EUROPEA, IN MASSACHUSETTS. 



BY DR. H. A. HAGEN, CAMBRIDGE, MASS. 



Professor Sereno Watson communicated to me some twigs cut on the 

 grounds of Mr. Henry Watson, in Northampton, Mass. Several Larix 

 Europea about thirty years old stand on an avenue, and have never 

 suffered before. In April they showed to a large extent pale needles and 

 many little larvse of the well known sac-bearing form. In May numerous 

 slate-colored moths appeared, the true Coleophora laricella Hub. This 

 insect in all its stages is well described in Stainton's Nat. Hist. Tineina, 

 vol. iv., p. I, and figured on pi. i., f. 2. It would be useless to give a 

 description here. Our biological collection possesses types of all stages 

 by Rosenhauer, Zeller and Hofmann. As far as I know, it has not yet 

 been observed in the United States. Some twigs given by the late J. Boll 

 were perhaps collected in 1872 in Cambridge, Mass.; but as he did not 

 mark any locality on the label, I am not sure that he did not bring them 

 over from Europe. I am not able to find any published notice in North 

 American papers. I may notice that the caterpillar keeps its abode very 

 clean by expelling the faeces out of a hole in the needles.
