 This form cannot be regarded as a distinct connecting 

 link between tricolor and Aspidiotus s. str. as its position at 

 the end of the table might indicate. It is rather a divergent 

 form, decidedly different from any other in the subgenus. 



POSTSCRIPT. 



Since the foregoing pages were printed, type specimens 

 of A. Jiuntcri and A. aiicylus var. latilohis have been exam- 

 ined by Mr. C. L. Marlatt of the U. S. Dept. of Agr. He 

 regards huntcri as identical with ostrcacforinis, and does not 

 recognize the var. latilobis as possessing characters dis- 

 tinguishing it from ancylns proper. 



E. Earnest Green, in a communication to the writer, 

 states that in all probability .1 cxdoniac is a synonym of 

 A. lataniae Sign. Prof. Green's conclusions are based upon 

 a study of the type specimens of the latter species in the 

 Vienna Museum. The results of his study will appear in a 

 coming number of the Entomologist's Magazme.
