(3) OF SANTA Kfi OXLT. 



The pear and cherry slug {Eriocampti cerasi I'eck) is well established in at least 

 two 8auta Fo orchards, and doing serious damage. 



The box-elder trees planted in the streets are doing very well, but some are aftected 

 by Aspidiotiis anci/las Putnam. There is also on these trees an apparently new species 

 of Lecaniuni, allied to L. persicce. L. persicw is above given for Mesilla Valley only, 

 but what may be the same has just been found, in Santa Fe on peach. One can not 

 pronounce verj'^ certainly as to these scales without a more careful examination than 

 I have yet found opportunity to make. 



Lecaitiian lu'spcridnm haaheen found badly injuring oleander, and also infesting 

 other plants in pots. It may here be mentioned, also, that in hothouses one finds 

 Dacti/lopiiis citri, AsjndiotuftJicHS, an<l Lecaniiim olew — the first two troublesome. 



Roses are aftected by a Lecapiitm 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 Ft. 



A Phlocotribun, which Capt. Casey thinks best referred as a variety to /'. liminaris, 

 attacks various fruit trees, viz, apple in Mesilla, plum and cherry in Santa Fo. It 

 appears only to injure trees which are failing in health from other causes, and is 

 thus not a very pernicious insect. 



Lygiis pratensis is common enough on alfalfa and elsewhere. 



The bean ladybird (-E^xVac/ma corrH^/a) seems eiiuaily injurious in both localities. 



The coru worm {Helwthis armiger) is similarly troublesome in l)oth places. 



Fieris protodice is likewise distributed; the same may doubtless be said of I'lusia 

 hrassicce. 



The Coruco {Cimex inodonis) of Las Cruces I have not seen at Santa Fe, though 1 

 saw more than enough of C. Jectularius. However, Mr. Boyle describes to me the 

 occurrence in numbers at Santa F^ of what could only be C. inodorus. 



Hi/phantria cunea, so excessively abundant ou the cottonwoods at Las Cruces, is 

 rather uncommon at Santa Fe, according to my observation. 



The screw-worm fly (Conqysovujiamacellaria) is common in both localities. 



(2) OF MESILLA VALLEY ONLY. 



The western June beetle {AUorluna mutahilis) is very common andrather variable; 

 8o far as known, its habits resemble those of the eastern representative of the genus. 



The tornillo bag-worm (Oiketicus toivnsendi), which occurs on the wild tornillo 

 {I'rosopis piibescens), 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 itot yet be said that we fully understand this pest. At Santa Fe there is also 

 a Prionus which very likely will prove injurious. 



The twelve-spotted cucumber-beetle (Diabrotica 12-punctata) is excessively abuu- 

 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 i)ut 

 it with the injurious insects "of Mesilla Valley only." 



The squash bug (Anasa iristis) is abundant and troublesome. 



The army worm (Lcncania unipuncta) did considerable damage last year. 



A mite {Bryobia pratoisis), 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.
