THE CANADIAN ENTOMOLOGIST. 09 



whose constant words of cheer I owe what h'ttle success I may have 

 achieved. Our minds moved in liarmonious accord ; our gifts were com- 

 plementary to each other, and in so far as one so insignificant might, I 

 helped my friend in my small way, a feeble return for his many kindnesses. 



Better than any, perhaps, I can gauge the loss to science by his 

 untimely death. His work planned, outlined in many a letter, carried out 

 with his enthusiasm, his thoroughness, his energy, was destined to place 

 him on the same lofty, still eminence where sits Stal alone, beyond the 

 reach of the petty bickerings and disputes of the pseudo-great.

A DECENNIAL CONFESSION. 



BY J. M. A L D R I C H, MOSCOW, IDAHO. 



In Entomological News, XI, 531, 1900, I published a list of correc- 

 tions to my work on Diptera up to that time ; the decade since then has, I 

 regret to say, furnished me with materials for a similar list at the present 

 time. With due humility I make the following confession : 



In the February, 1909, number of the Canadian Entomologist I 

 published a paper on Rhagoletis, describing a new species, intriidens^ 

 which had injured cherries in British Columbia and presumably in Idaho. 

 Immediately after the publication of the article, Mr. Coquillett informed 

 me that my new species was the same as Osten Sacken's y"rt//j/rt!, of which 

 he had material from the type locality. Since then I received a pair of 

 fansta from M. C. Van Duzee, collected at Kearney, Ont. There is no 

 doubt that I misunderstood a statement of Osten Sacken's, where, after 

 mentioning the basal cross-band of the wing, he goes on to say, "The 

 black colour begins exactly where it does in fig. 10, and encloses a hyaline 

 triangle reaching from the costa to the interval between the third and fourth 

 veins." Eastern specimens prove that this statement refers to the black 

 colour in general, not to the basal cross-vein. 



In the same article I should have included in the table Rhagoletis 

 grindelice Coquillett, (Proc. Ent. Soc. VVash., IX, 146,) reared from flower- 

 heads of Griudelia sqnnrrosa at Clarendon, Texas ; it is readily dis- 

 tinguished from all the species in my table by having the scutellum wholly 

 black. The life-history of Rhagoletis suavis Loew, was already known, 

 having been published by Babb, (Ent. News, XIII, 242) ; the larva lives in 

 the outer hull of growing walnuts at Amherst, Mass. So there are six 

 species with larval habits known, instead of four.
