THE CANADIAN ENTOMOLOGIST. 215 



All of the above species, except the first two, have been cited by 

 many authors under various names. The following are some of them : 



Lccanium hesperidiim, L, — Z. lauri^ Boisd., perhaps is the same. 



Asterolccanhim hederce, Licht., was described as Plaiichonia hederce^ 

 and again re-described as Plaiichonia Valloti , Licht., and probably 

 Asterolecaniiim massalongianum, Targ., is the same. 



Dadylopius citri, Risso., has the following synonyms : destructor, 

 Comst. ; farinosus, Deg.; phyllococcus, Ashm.; brcvispiniis, Targ. 



Aspidiottis rapax, Comst. Synonyms : camellice, Sign.; citri, 

 Comst.; ei'onymy, Targ.; /ucumce, Ckll. and Town. 



Aspidiotus heden^, Vail. — For a long list of supposed synonyms of 

 this species see Prof. Cockerell's first supplement to the Check List of the 

 Coccidse, 23 in all, after Berlese and Leonardi. 



Aspidiotus Crawii, Ckll. — I retain this as being a valid species, 

 although Mr. Marlatt finds it to be A. cydonice, Comst. He may find 

 something else on the leaf or twig than is indicated by the label, and 

 should not assume that the writer of the label saw it and confused it with 

 the species indicated. Two are more species are often found upon the 

 same leaf and twig. Aulacaspis elegans, Leon, found by me on Cycar- 

 revoluta in a greenhouse at Lawrence, Mass., had mixed with it on 

 the same leaf Aspidiotus hederce, Vail. Neither can the proportional 

 number be estimated, by any means, by those found on a slide mount. 



Chrysoinphalus aonidum, L., as Coccus aonidujn, L.; Chrysomphalus 

 ficus, Ashm., and Aspidiotus ficus, Ashm. 



C. dictyospenni, Morg., as Aspidiotus dictyospermi, Morgan, and 

 C. dictyospenni, \a.\-. jainaiccnsis, Ckll. (minor, Berlese).
