sion and loaned to Dr. Fletcher for use in an article upon this species 

 which appeared in his entomological report for the year 1898 (1899, 

 pp. 207-210). The other illustrations are from photographs by Mr. 

 Carew-Gibson. 



This species, represented in the adult form at a of figure 21, resem- 

 bles rather closely Callidium, as also Asemum, being related to both 

 genera. It is deep, dull black in color, rather sparsely pubescent, 

 and of inconspicuous appearance, measuring about half an inch in 

 length. No description of the larvae or pupae has yet been made, but 

 their general appearance can be made out from the accompanying 

 illustration. 



One of the remarkable features about this attack is that previously 

 the species was, and in fact still is, a rarity in collections. Injury was 

 also noticed at Victoria by R. M. Palmer, and the infested bushes were 

 traced to a nursery company at Salem, Oregon. Several hundred trees 

 were condemned and destroyed, and it is hoped that the species has 

 been effectually checked, if not exterminated, in the infested region. 



Little is known of the life history of this gooseberry borer. Mr. 

 Carew-Gibson, however, made some observations. A larva which he 

 had under notice transformed to pupa August 19, and appeared as 

 imago eighteen days later. A beetle was also found ready to emerge 

 from a twig September 13. Only a single larva is to be found in each 

 affected bush. The larva is described as generally starting in from a 

 convenient crotch somewhere about where the branch makes a fork 

 (and where the eggs are perhaps laid by preference); then working- 

 downward and apparently wintering in the roots. In one case noticed 

 the larva had worked so near to the earth that there must have been 

 only the thinnest possible covering between it and the soil; it then 

 appeared to bore upwards, after the manner of the raspberry cane- 

 borer, and after reaching some inches above ground made a chamber 

 with a very thin covering dividing it from the air; in this the insect 

 pupated. From two reared beetles an egg was obtained on the 15th 

 of September. 



METHODS OF CONTROL. 



Until we know more concerning the life history and habits of this 

 gooseberry borer, no other remedy can be advised than the cutting 

 out and destruction by burning of the injured plants as soon as they 

 are detected, If future observations should show that the same insect 

 attacks also currants, which seems probable, it will be necessary for 

 the protection of one plant to adopt the same measures with the other.
