these all stout, with one very long. The measurements of the several 

 joints are as follows : 



The approximate formula will 56345128(67). There are a number 

 of long, thin hairs between the antennas, very variable in length, 136, 80, 

 56 and 40. There are also some short, spine-like hairs. 



Hab. — At Mountain View, California, on alder and willow ; found 

 May 3rd, 1899, °y Mr. Edw. H. Ehrhorn. It is a very distinct species 

 and can be separated easily from its nearest American ally, Pulvinaria 

 occidentalism by the antennae. I take pleasure in naming this insect after 

 Mr. Ehrhorn, in recognition of the fact of his good work done in the 

 discovery and technical study of the Coccids of California. So far as 

 known at the present time, this makes the fifteenth species native to the 

 United States ; and P. Hunteri is the fourth species found to infest 

 maple. 



I take this opportunity to record the finding of Dactylopius Kingii, 

 var. Neo-Mexicana, Tinsley, in nests of Lasii/s Americanus, Em., at East 

 Las Vegas, New Mexico, by Prof. Cockerell, and also Riper sia ftaveola, 

 Ckll., at Gullinas Canon, New Mexico, by Prof. Cockerell and Mrs. 

 Wilmatte Cockerell, under a log in the transition zone, altitude about 

 7,500 feet. The same species was found by Mrs. E. L. Hewett and Mr. 

 Cockerell at East Las Vegas, N. M., in the nest of Lasius, sp. Hitherto 

 this species was only known from Massachusetts, from ants' nests. — G.B.K. 



TYPES AND SYNONYMY. 



BY JOHN B. SMITH, SC D., RUTGERS COLLEGE, N. J. 



Two papers in the last (April) number of the Canadian Entomolo- 

 gist are of great interest to me, and both on the same general topic 

 applied to very different species. Mr. Lyman makes an earnest effort to 

 save Mr. Walker's name Spilosoma congrua, and gives all the facts 

 relating to the name, its publication and subsequent history ; upon which 

 facts Mr. Lyman and Sir George Hampson reach opposite conclusions. I 

 have no liking for Mr. Walker's species, but I think I would side with Mr.
