(3) OF SANTA FE ONLY. 
The pear and cherry slug (Eriocampa cerasi Peck) is well established in at least 
two Santa Fe orchards, and doing serious damage. 
The box-elder trees planted in the streets are doing very well, but some are affected 
by Aspidiotus ancylus Putnam. There is also on these trees an apparently new species 
of Lecanium, allied to L. persicce. L. persicce is above given for Mesilla Valley only, 
but what may be the same has just been found in Santa F6" on peach. One can not 
pronounce very certainly as to these scales without a more careful examination than 
I have yet found opportunity to make. 
Lecanium hesperidum has been found badly injuring oleander, and also infesting 
other plants in pots. It may here be mentioned, also, that in hothouses one finds 
Dactylopius citri, Aspidiotus ficus, and Lecanium olece — the first two troublesome. 
Eoses are affected by a Lecanium which, superficially at any rate, looks like L. 
rosarum Snell., of Europe. I am informed that roses have been imported to Santa 
F6 direct from France, and this may well have come with them. 
(B) NATIVE SPECIES. 
(1) OF BOTH MESILLA VALLEY AND SANTA FE. 
A Phlceotribus, which Capt. Casey thinks best referred as a variety to P. UminaHs, 
attacks various fruit trees, viz, apple in Mesilla, plum and cherry in Santa Fe. It 
appears only to injure trees which are failing in health from other causes, and is 
thus not a very pernicious insect. 
Lygus pratensis is common enough on alfalfa and elsewhere. 
The bean ladybird (Epilachna corrupta) seems equally injurious in both localities. 
The corn worm (Heliothis armiger) is similarly troublesome in both places. 
Pieris protodice is likewise distributed ; the same may doubtless be said of Plusia 
brassicce. 
The Coruco (Cimex inodorus) of Las Cruces I have not seen at Santa Fe, though I 
saw more than enough of C. lectularius. However, Mr. Boyle describes to me the 
occurrence in numbers at Santa F6 of what could only be C. inodorus. 
Hyphantria cunea, so excessively abundant on the cottonwoods at Las Cruces, is 
rather uncommon at Santa Fe", according to my observation. 
The screw-worm fly (Compsomyia maceUaria) is common in both localities. 
(2) OF MESILLA VALLEY ONLY. 
The western June beetle (Allorhina mutabilis) is very common and rather variable; 
so far as known, its habits resemble those of the eastern representative of the genus. 
The tornillo bag-worm (Oiketicus townsendi), which occurs on the wild tornillo 
(Prosopis pubescens) , has taken to the cultivated locust, and more especially to the 
apple. So far, it has not become sufficiently numerous to do very much harm. 
The Prionus borer in fruit trees is said to cause the loss of many trees, although 
it can not yet be said that we fully understand this pest. At Santa F6 there is also 
a Prionus which very likely will prove injurious. 
The twelve-spotted cucumber-beetle (Diabrotica 12-punctata) is excessively abun- 
dant, and must be held responsible for a fair amount of damage. At Santa Fe this 
species has been taken by one of the Boyle family about two years ago ; but I have 
not myself met with it there, so it must be too scarce to be injurious. Hence I put 
it with the injurious insects " of Mesilla Valley only." 
The squash bug (Anasa tristis) is abundant and troublesome. 
The army worm (Leucania unipuncta) did considerable damage last year. 
A mite (Bryobia pratensis), identified by Mr. Howard, abounds on apple and pear 
trees, causing the leaves to turn yellow. I place it with doubt as a native species ; 
very likely it was imported from the Eastern States.
