172 FREDERICK BLANCHARD. 



Allorhina mutabilis Grory and A. nitida Linn. The two species 

 which bear these names in our cabinets are not correctly separated by 

 most collectors. The first is found only in the extreme southwest of our 

 territory, in Texas and Arizona. It is usually larger in size and of more 

 robust facies than niticht, and similar in color, but is more apt to have 

 the sides of the elytra more widely ochreous, or the entire surface may 

 be of that color or ferruginous. The clypeal horn is usually longer, 

 broader at its free end, and frequently feebly emarginate. The side mar- 

 gin of the thorax is more widely beaded and more obtuse, especially near 

 the base. The median lobe of the base of the thorax is shorter and 

 more obtusely rounded at apex. A. nitida occurs in the entire Atlantic 

 region extending to Texas. The clypeal horn is usually narrower at tip, 

 obtuse, but sometimes quite acute. The bead of the lateral margin is 

 always very narrow, almost obsolete in front and never broad and thick 

 posteriorly. There are other species in Mexico allied to these but it is 

 impossible at present to fix the limits of true species until all are studied 

 with abundant material. 



Euphoria subtomentosa Mann, and leucographa G. et. P. Dr. 

 Horn requests that I here announce the occurrence of these two species 

 in Arizona in sufficient numbers to warrant their introduction into our 

 lists. 



E. leucographa is similar in form and sculpture to melancholica, but 

 is rather less robust. Its general color is reddish brown with slight 

 metallic lustre, the thorax with two discal piceous spaces, the elytra with 

 narrow undulating bands of whitish pubescence as in sepulchralis. 



E. subtomentosa is of the form of sejyulchralis, the color piceous or 

 nearly black, varying to pale reddish brown with numerous patches of 

 white arranged so as to form a design very nearly resembling the dispo- 

 sition of the yellow and black colors on the elytra of E. Kernii.
