ENTOMOLOGY 271 



beginning of March few eggs remain, the larvae are generally covered 

 and the majority of all the insects are females ready to reproduce. 

 During May and June eggs and active larvae are most commonly 

 present, and there seems to be a continuous breeding throughout the 

 season without a regular division into broods. 



The larvae are dull orange in color, with well defined black eye 

 spots and well marked antennae and legs. Unlike most other scale 

 insects this larva, when it has once set, does not immediately cover 

 itself with a waxy secretion. It may remain for several days entirely 

 naked, and scale growth is both irregular and slow. If there are only 

 a few of the insects and the plants are vigorous, no perceptible harm 

 will be done ; if the plants are well set with fruit or flowers and not 

 too well fed, the scales sometimes cause considerable injury. 



In the garden all that is usually necessary to control this insect 

 is to admit light and air and to cut out the worst infested shoots. 

 Rose plants can, as a rule, be entirely cleaned in this way, and black- 

 berry and raspberry plants need little more. Judicious trimming in 

 winter will be all that is necessary in most cases. 



Sometimes rose plants are so situated that cutting back is not de- 

 sirable and then a resort to insecticides is necessary. Winter applica- 

 tions are best and any of the winter washes recommended for the 

 pernicious scale will answer. The covering is thicker than that of 

 the scurfy scale ; but is not so resistant as that of the other species here 

 mentioned. As the insects pass the winter in all stages, one applica- 

 tion may not be sufficient, and it will be better to make another toward 

 the latter part of May, when those forms that were in the egg stage 

 and most probably escaped will be in a condition to be reached by 

 insecticides. (Bui. 181 N. J. E. S.) 



The Rosebud Curculio. This occurs very commonly on wild 

 and cultivated roses in Montana. The beetles are rather shy when 

 discovered, and though their movements are not quick, they soon 

 disappear under a leaf or stem when a person approaches. In com- 

 mon with many other insects, they have the habit of drawing in 

 their legs when in danger and allowing themselves to drop to the 

 earth, where they remain motionless for a short time, or until the 

 danger has passed. This is doubtless an effective means of protection 

 against natural enemies. 



The colors found on the beetle are red and black. The wing 

 covers, which make up the greater part of the upper surface of the 

 body, and the thorax (prothorax) are red, while the head, including 

 the beak or snout, the antennae, the legs, and the entire under surface 

 of the body are black. 



The beak or snout is long and slender. The antenna? are club- 

 shaped and are attached near the middle of the snout, one on each 

 side. The mouth parts are situated on the extreme end of the beak, 

 and are made up of a number of pieces, the most formidable of which 

 are the mandibles, which are toothed on both the inner and outer 

 edge. Exclusive of the beak the beetle measures u little less than 

 one-fourth of an inch in length.
