THE CANADIAN ENTOMOLOGIST. 257 



seen, and the finding of a Eulecaniiim on an • herbaceous plant was 

 contrary to all preconceived ideas ! What was I to do ? — call it a new 

 species? Close by was a peach tree, on which were a {^"n ordinary Z. 

 persiccE, and here of course was the explanation. But had I sent the 

 umbellifer scale away to some entomologist, with no information about 

 the adjacent persicce, I really don't see how he could have guessed what 

 it was — the thing was so starved and altered by its unwonted food ! 



All these remarks will naturally tend to produce the impression — 

 doubtless correct —that we have too many nominal species oi Eulecanium 

 in the books. But if we must distinguish species with caution, so also 

 must we lump them with caution. It is a stupid way out of the difficulty 

 to throw all those together that we cannot quite easily separate. 



(5) Lecanium 7-obiniarum, Douglas. In May, 1894, I bred a 

 parasite from scales of this species found on locust in Las Cruces, N. M. 

 Mr. Howard identifies it as Blastothrix longipe^mis, Howard, and states 

 that it has previously been reared from several Lecaniines. 



On osage-orange in Las Cruces, I find a scale just like Z. robiniaru77i, 

 but perhaps a little more shiny and more decidedly pruinose. But the 

 eggs of the osage-orange form are always pure snow-white, while those of 

 Z. robuiiariun are salmon-pink ! 



(ii.) Lecanium, other sections. 



(6) Lecafiiiiin pef/oratum, Newstead. A flat species with 8-jointed 

 antennae, found on palms. Mr. Ehrhorn sent me specimens from a 

 greenhouse in San Francisco. Miss Mary W. Tyrrell, of Oakland, sends 

 me a very pretty enlarged photograph of this insect, which she regards as 

 Z. tesseliatian, Signoret. While I cannot very well doubt that it is 

 Newstead's Z. perforatum, I must confess that I am not well-satisfied 

 about its distinctness from tessellatum. It does not seem, however, to 

 be the same as the Jamaican species on lignuni-vitje, which I had 

 regarded as tessellatum, though the two things are very much alike. For 

 the present, no more can be said, though it seems likely that the 

 Jamaican insect will need a new name. 



(7) Lecanium olece (Bern.). Prof. Tourney sends this on orange 

 from Arizona; and Mr. Lataste found specimens in Chile, on Yucca in a 

 garden. In both these cases it has of course been introduced.* 



"In both cases the names of the exact localities were sent, but I regret that I am 

 totally unable to decipher them. Will correspondents please write names of localities 

 plainly ?
