Later studies make it desirable to add a few words. In Palvi- 

 naria lutea I remarked on the long bristle on the inner side of the 

 femur. 1 now believe that this is on the end of the trochanter, as 

 is seen in other species. The trochanter appears to be unusually 

 long and its articulation with the femur difficult to observe. From 

 this correction it follows that the femur itself is shorter than I 

 supposed. The Geroplastes on Artemisia was expected to prove 

 identical with one from New Mexico, which has been named C. arte- 

 misiix by Dr. Riley, but not described. However, I sent some to 

 Dr. liiley, and hear from him that they are distinct — which is 

 curious, since they live on the same genus of plants in the same 

 zoological subregion. My insect, which is curiously irregular in 

 form, will be called C. artemisiarum, sp. n. The other '■'■Ceroplastes" 

 alluded to, on a spiny shrub, has a glassy rather than waxy scale 

 and 7-joiuted antennae, wherein it agrees not with Cei'oplastes, but 

 with the New-Zealand genus Inglisia, Maskell. I call it, therefore, 

 Inglisia nivea, sp. n. T. D. A. Cockerell.

Mr. Robert Newstead, to whom I sent specimens of Pulvinaria 

 lutea, remarks that in structure the ovisac agrees not with trae 

 Pulvinaria, but with the closely allied genus Lichtensia, Sign. At 

 the same time he kindly sends me specimens of L. viburni, Sign, 

 (the only known species of the genus), which were found at Llandaft", 

 Wales, by Mr. B. Tomlin. P. lutea and L. viburni differ very 

 greatly in superficial appearance ; but, as Mr. Newstead states, they 

 show some generic points in common. Detailed comparisons will be 

 made, and reported on in some future paper. T. D. A. C.
