While making a study of the Coccidre representing the genus 

 A'^pidiotus {sens, latiss.) in tiie collection of Cornell University, I found 

 two undescribed species ; both are from the United States. These species 

 are characterized as follows : 



Asp idiot us oxy coccus, n. sp. (Fig. 9.) 



Scale. — The scale of the female is almost flat, and very variable in 



shape. It is usually circular, or nearly so, but may be elongate with sides 



parallel. The scales on the upper surface of the leaves are black ; those 



on the under surface are dirty gray to dark brown, usually the lighter

colour. Exuviae are central to sub-central. The younger scales have the 

 exuviae marked by a small brown or blackish nipple-shaped process, which 

 often disappears in the older scales, leaving the yellowish-orange exuviae 

 exposed. The secretion covering the remainder of the exuviae is of a dirty 

 gray colour, and usually presents a marked contrast to that part of the 

 scale immediately surrounding it. The scale of the male is similar to that 

 of the female in size and colour. It is elongate with sides parallel 



Fejiiale. — -The female is dull brown, broadly pyriform, about .47 mm, 

 broad by .57 mm. long. The pygidiiif?i is furnished with two pairs of lobes.
