result was simply astounding ; after an hour's work I was obliged 

 to give up, as darkness had set in. When I arrived at home I 

 counted ni}' captures, and found that I had got 280 pupte of 

 various kinds. Doubtless I could have taken as many or more 

 larvae, but I left them to pupate in due course. I have been 

 several times since then and taken more pupae, but the hyberna- 

 ting larvae are as plentiful as before, not having yet pupated. I 

 send tiiis as an encouragement to pupa-diggers, who no doubt 

 have been often disappointed as I have. The best places ai'e the 

 hunnnocks of couch grass (Triticum) ; dig under them about four 

 inches from the surface, and tap the sod, when the pupae come 

 tumbling out eight and ten at a time. — John N. Young; 85, Filey

The Colorado Beetle. — In the February number of the 

 'Entomologist,' Mr. T. D. A. Cockerell mentions with some 

 surprise the rarity of Cltrysomella lO-lineata in Colorado, and 

 rather doubts the occurrence of the species there. There is no 

 question of the occurrence of the insect in Colorado ; but it is 

 rare where the cultivated potato does not offer an attraction and 

 an artificial field for its increase. For some time after its 

 discovery it was comparatively an uncommon species, feeding on 

 Solanum in little colonies here and there as with other species, 

 and kept in check by its natural enemies. When the cultivated 

 potato reached this belt the conditions changed, and it began to 

 spread with great rapidity along this line of cultivation, until it 

 became the destructive pest we now know it. A similar instance 

 of rapid spread is found in the case of Aramigus fidleri, Horn. 

 When first described, in 1874, but a single specimen from 

 Montana was known, and for two years thereafter it remained a 

 rarity. Suddenly, however, in 1870 it began to come in from 

 growers of roses, in great numbers, from all parts of the country, 

 with complaints of injury caused, until " Fuller's Rose-beetle" is 

 well known to, and dreaded by, owners of hothouses everywhere. 

 It is just as rare in Montana, however, as it was when first 

 described.— John B. Smith; Washington, D.C, U.S.A.

 Mr. Adkin's note), for " remote " read '* recent " ; and the

 to refer are, 1 am aware, mucli too recent," Sec.
