orange-red in the latter part of their periods". Elsewhere in 

 his paper he tells us that these larvae are entirely devoid of the 

 the so-called "breast-bone", and in still another place expresses 

 the suspicion that the species was originally a native of some 

 tropical region, as they were not known to attack roses in the 

 open air. Summarizing this information, then, we have a 

 peculiar injury to roses, especially to the Meteor, a variety 

 originating in Europe, occurring in widely different localities, 

 due to two species of insects, working to all appearances pre- 

 cisely alike, and reared from infested plants growing in Wash- 

 ington. Apparently the same species was sent to the U. S. De- 

 partment of Agriculture from Cleveland, Ohio, in 1903. 



On May 16, 1903, a firm located in the vicinity of Chica- 

 go, engaged in growing roses extensively under glass, advised 

 the State Entomologist of serious trouble among their Meteors, 

 evidently due to a minute white worm which attacked the 

 buds and destroyed them. Early in June, Mr. C. A. Hart, being 

 in that vicinity, visited the premises by Dr. Forbes's direction, 

 and brought some of the affected buds to the office. The larvae 

 found in them were very small, white, except those seemingly 

 full grown which were tinged with orange, and the so-called 

 "breast-bone" was clearly present. 



The matter was now placed in my hands for investigation, 

 and on June 11, acting under instructions, I visited the rose- 

 houses containing the injured plants. Larvae were found in 

 the young rosebuds of both leaf and blossom, but more abun- 

 dantly in the latter, and also eggs, which, from their position in 

 these buds, indicated that they were those of the same species 

 as the larvae. Several very minute female midge-like flies were 

 also taken, seemingly in the act of ovipositing in the blossom 

 buds. 



SPECIES DIFFERS FROM THOSE PREVIOUSLY DESCRIBED. 



The larvae found in the rosebuds did not agree with those 

 described by Mr. Coquillett, but, like those brought home by Mr. 

 Hart, possessed the "breast-bone", and the older individuals were 

 not an orange-red color, but slightly tinged with orange with-
