fruit. Egg laying begins in Bozeman about June 1, and by about 

 July 15 the bulk of the feeding is completed and pupation has taken 

 place. The fresh adults begin to appear on the bushes about July 20 

 and continue until about August 1, when all have disappeared, having 

 gone into hibernation. 



Detailed descriptions and control measures are left for future publi- 

 cation. We are indebted to Mr. W. Dwight Pierce for the determi- 

 nation of the name of this beetle. Mr. Pierce has also determined for 

 us a parasite which was bred in considerable abundance from this beetle 

 as Catolaccus sp. The common name, "The Currant Fruit-Weevil" 

 is proposed for this insect. 



For several years we had noticed a peculiar injury to the tender, 

 terminal growth of gooseberries and red and black currants in Bozeman. 

 The leaves of the affected stems were distorted, undersized and showed 

 distinct spots or markings which suggested the attacks of some insect 

 with piercing mouth-parts. The injured stems were reduced in size 

 and in length and, as all of the stems on the bushes were more or less 

 affected, the bushes showed distinct injury. The cause of the injury 

 was explained when in 1912, a large black thrips was found feeding on 

 stems which showed such injury. A number of the living insects were 

 placed on fresh gooseberry shoots in the insectary and the young were 

 reared. Since then we have repeatedly found both adults and young 

 on gooseberry and currant and it is perfectly clear that a definite and 

 characteristic injury which at times may be rather severe is attribu- 

 table to this species. 



Specimens were sent to Mr. J. Douglas Hood of the United States 

 Department of Agriculture, who found them to be of a new species 

 which he names Liothrips motitanus (See "Nine New Thysanoptera 

 from the United States," J. Douglas Hood, Proceedings Biological 

 Society of Washington, Vol XXVI, June 1913, p. 163). 



More recently this insect has been found in Sixteen Mile Canyon in 

 Montana, feeding on the native wild gooseberry {Ribes setosum Lindl.), 

 and causing the same characteristic injury. 



The details of the life history and habits have not been worked out, 

 but the following notes may be given : 



The adults appear on the bushes soon after growth starts and later, 

 the young, which are bright red with black head and legs, may be 

 found. The hatching of the young is strung out for several weeks. 

 The first young appear about the middle of June and we have found 

 young just hatched on July 12; in the latter part of July only adults 

 are found and these disappear during the summer. The species 

 apparently hibernated as an adult. 



Preliminary tests with insecticides have been made, using commer-
