seen the specimens. I can only say that 

 the types of rufoscutellatiis do not fit the 

 description of misella — and this most 

 decidedly. I cannot account for such a 

 reference as this, and on so uncertain 

 and ill-founded a basis. 



Mr. Ball's guess concerning ti:ag/ius 

 as a form of califortiicus may possibly be 

 correct. I guessed the same before de- 

 scribing them. However I had no proofs 

 to bear me out, nor has Mr. Ball sub- 

 mitted any. If they did not represent 

 species they certainly would varieties. 

 Mr. Ball does not even allow them varietal 

 standing, but in the same breath bases 



a " var. nov." on specimens of laeta 

 " suffused with reddish." This reddish 

 suffusion is a character not uncommon 

 among various other Jassids. The ref- 

 erence of these species to humHis is 

 wholly the most superficial guesswork. 

 It is needless to say that the word " pro- 

 notum " in the fourth line of the descrip- 

 tion of tnag/ius is a missprint for " elytra." 

 The species idioceroidcs does belong in 

 the genus Macropsis as it is at present 

 defined. Mr. Ball might just as well 

 separate it as a new genus. It would be 

 just as good a one as many others in 

 the Jassidae. 



COCCIDAEOFTHE HARVARD BOTANICAL GARDENS. 



BY GEO. B. KING, LAWRENCE, MASS. 



The following is the result of two brief 

 visits to the Harvard Botanical Gardens 

 at Cambridge, Mass. The first was on 

 July 15 of this year, in company with 

 Mr. A. F. Perry. Just two hours' work 

 was put in at this time. The next visit 

 was by myself on August 13 ; about three 

 hours were spent about the garden and 

 greenhouses. Although we found a large 

 number of coccids to inhabit this beauti- 

 ful garden, we have by no means got all 

 that really exist there. Other visits are 

 contemplated and it should be said that 

 a splendid opportunity presents itself 

 here for students to study the life history 

 of many interesting and injurious coccids. 

 Several species are here cited for the first 

 time, together with many new food 



plants, which adds considerably to our 

 Massachusetts list. 



1. Lfcaniu7n pruiiiosiim Comst. MS., 

 Coq. were found on Prunics domestka, 

 var. Brads/unvi, recorded here for the 

 first time from Mass. The food plant is 

 also new. 



2. Lecanium qitercitronis Fitch, on 

 Xanthoxylum americanum a new food 

 plant for this scale. 



3. Lecanium longulum Dougl. on Mon- 

 siera deliciosn, in the tropical greenhouse. 

 This scale is of recent introduction, and 

 new to Mass. ; the food plant is also 

 new. 



4. Lecanium meialeucae Mask, on the 

 same plant as the latter in the tropical 

 greenhouse, and is of recent introduction
