raspberries. Entrance is made near the top of the shoot in a leaf axil, 

 which was probably in the top bud at the time the egg was laid, and from 

 this entrance the larva works its way in an irregular course down 

 through the pith until it comes within a few inches of the ground, when 

 it girdles the canes as represented in the extract. As soon as the top 

 wilts the maggot continues its course downward through the pith. 



Careful search was made in neighboring berry patches and in our 

 own at the college, but nothing more of the kind was found. Not so 

 much would have been thought of this one local injury had not there 

 come a letter from Costello, Pa., about two weeks later, describing the 

 work and maggot exactly at that place. It was stated that the injury 

 was considerable in the locality. This made me think that perhaps the 

 species is more widespread than thought at first. Every effort was 

 made to rear the maggots which I had, and I w^as successful for some 

 time by transferring them every few days to fresh shoots. The last 

 maggot reached a length of 11""", when it died. 



ADIMONIA CAVICOLLIS ON CHERRY FOLIAGE. 



A correspondent at Bellaire, Mich., sent me specimens of this Chrys- 

 omelid the latter part of May, saying that they were causing damage 

 to cherry trees of that locality. On investigating the life history of 

 the species I find that it is reported by Packard in Forest Insects under 

 Galeruca sanguinea as found abundant in New Hampshire on wild 

 cherry. 



Like so many insects that we find each year, the Adimonia has in 

 some way found that a cultivated plant closely related to its old food 

 plant is preferable, and is making the most of the newly found jdant. 

 The beetle is spoken of by Mr. Schwarz (Insect Life, vol. vi, p. 94) as 

 being a common northern species, and we may possibly yet find it quite 

 a serious pest. 



In response to my inquiry my correspondent wrote that there were 

 wild cherry trees not far away, with a few of the beetles on them. 

 Larvte received July 10 were about 5""" long, not very broad, and 

 tapering posteriorly. Head, legs, pronotum, and terminal plate black 

 in all the specimens, except one which was larger, and these parts in 

 that one are reddish brown. On the dorsum of each segment are two 

 transverse rectangular parallel dark spots, with two or more smaller 

 ones on the sides at the end of the large ones, and beneath these is a 

 longitudinal block on each segment. The venter of each abdominal 

 segment is marked with five dark brown spots, the central one being 

 largest. 



NOTOXUS ANCHORA EATING CHERRIES. 



In connection with the Adimonia this species of Notoxus might be 

 menticmf^d. It was reported from northern Michigan as collecting in 

 large numbers on nearly ripe cherries and eating the contents from
