Later studies make it desirable to add a few words. In Pulvi- 
naria lutea | remarked on the long bristle on the inner side of the 
femur. I 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 1 
supposed. The Ceroplastes on Artemisia was expected to prove 
identical with one from New Mexico, which has been named C, arte- 
misie by Dr. Riley, but not described. However, I sent some to 
Dr. Riley, 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-jointed antenne, wherein it agrees not with Ceroplastes, but 
with the New-Zealand genus Jnglista, 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 true 
Pulvinaria, but with the closely allied genus Lichtensia, Sign. At 
the same time he kindly sends me specimens of L. vibwrni, Sign. 
(the only known species of the genus), which were found at Llandaff, 
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 pointsincommon. Detailed comparisons will be 
made, and reported on in some future paper. T: DAG:
