PSYCHE. 



117 



infesting various species of oaks, and 

 one lot from Ulmus amerkana ; this was 

 also infested with Chioiiaspis americana 

 Johnson. L. qiiercitroiiis is new to Mass. 



(2) Lecaiiium lauri Boisd. on Lati- 

 rus nobilis, new to Mass., on a plant in 

 the Springfield Natural History Mu- 

 seum. 



(3) Lccaniian tiilipiferac Cook on 

 Liriodciulioii tulipifera, new to Mass. ; 

 this is probably L. Uriodcndri Gmel., 

 1788. Although his description is very 

 poor, Prof. Cook's is not very much 

 better and the insect should be rede- 

 scribed. 



(4) Lecaiiium canadense Ckll. was re- 

 ceived on elm twigs. 



(5) Lecanium cockerclU Hunter was 

 found on Populus sp. 



(6) Lecanium armeniaciim Craw, on 

 black cherry [Fruniis serotina) . I find 

 the same individual variation of the an- 

 tennal segments as did Mr. Hunter in 

 his Kansas specimens ; it is new to 

 Mass. Dr. Dimmock informs me that 

 the dates of hatching were from 26 June 

 to 8 July, 1898. 



(7) Lecanium quercifex Fitch on va- 

 rious species of oak twigs, and RJuis 

 glabra a new food plant, and a very 

 common species. 



(8) Lecanium corylifcx Fitch, on 

 Corylus americana. 



(9) Lecanium antcnuafum Sign, on 

 black oak ; only two examples of this 

 were found, but Brof. Cockerell's notes 

 are so clear on this species, that there 

 is no doubt as to the identity of the spe- 

 cies sent me ; it is new to Mass. 



(10) A species very much like Le- 

 canium bitubcrculatum Sign, new to 

 Mass., and needing further study, was 

 found on oak. 



(11) Lecanium hemisphaericum Targ. 

 on Cycas rej'oiuta in the Springfield 

 natural history museum. 



(12) Fulvinaria itmumerabilis Ra- 

 thv. on Qucrcus i/icifo/ia, Euonymus 

 americana., and Viburnum dentatum. 



{11) Fulvinaria mac/urae Kenn. in 

 Fitch on Ampelopsis guinquefolia, a new 

 food plant.

 on sugar maple in deep woods, new to 

 Mass. 



(15) Kermcs /f'/«^/V Ckll. one exam- 

 ple on oak. 



(16) Dactylopius loiigispinus Targ. 

 on Cycas revoluta in the Springfield 

 natural history museum. 



(17) Cliionaspis americana Johnson 

 on Ulmus americana with Z. qucrcitronis. 



(18) Cliionaspis ortlwlobis Comst. on 

 Populus grandidentata ; this seems to be 

 quite common at Springfield as I have 

 received several lots. 



(19) Cliionaspis furfurus Fitch on 

 Amchvhiiier canadensis, Populus grattdi- 

 dcntata and apple ; P. grandidentata is a 

 new food plant. 



(20) Cliionaspis pinifoliac Fitch on 

 Pinus sp. 



(21) Myiilaspis ulmi L. ; this is very 

 common on ash (^Fraxinus americana) 

 Acer rubrum, willow, Populus tremuloides, 

 L'. grandidentata, red root or New Jersey 

 tea plant (Ceanothus atnericaniis) Sassa- 

 fras officinale, and Ohio buckeye {Aescu-
