Dr. Uliier records the capture of this fine insect in New Mexico 

 and Texas, and Mrs. Slosson has taken it in Fh)rida. 



iVIiirgantia histrionica Halm. 



This common cabbage pest of the southern States has spread 

 northward to the vicinity of New York City, southern Ohio, Indiana, 

 Kansas, Colorado and California. Prof. Osborn thinks it has about 

 reached the northern limits of its distribution (Proc. la. Acad. Sci., 

 I, pt. iv, p. 121, 1893). 



''''i^Iur;»;aiitia varicolor Westw. {munda Dallas). 



Accredited to "Western States" in Uhler's Check List. 



Murgaiitia violasceus Westw. 



Mr. G. Beyer of New York City has recently sent me a pair of 

 this beautiful species taken by him at Key Largo, Florida. This is 

 its first recorded occurrence within our territory. It may be distin- 

 guished fr(jm munda by the markings of the scutellum and elytra 

 which have been carefully described by Dallas. In violascens the 

 median pale line of the scutellum reaches the apex, before which it 

 is joined l)y the pale lateral vittse, and the membrane is fuliginous 

 with a hyaline border. 



Vulsirea violacea Fabr. 



I am indebted to the kindness of Dr. Uhler for an example of 

 this beautiful species that was taken in Florida, and Mrs. Slosson 

 has another taken in the same State. I do not find that this species 

 has before been recorded from our territory.
