THE CANADIAN ENTOMOLOGIST. 259 



In the large digitules of the claw it resembles sinnihms ; hi the 8-jointed 

 antennae, urbicola. In the ovisac it rather resembles simulans than 

 urbicola ; in fact, its external appearance is practically the same. In 

 simulans the fourth joint of the antenna is very short ; in our insect it is 

 much longer than 6 or 7, and somewhat longer than 5. This comes 

 nearer to the condition of urbicola. All things considered, perhaps it 

 would be best, for the present, to call our insect P. simulans, variety. 

 P. bigelovice, Ckll., is another species of the same group. 



( i V. ) Asterolecanium. 



(11) Asterolecajiiumpustulans {CV.W.). On oleander from Honolulu; 

 sent by Mr Ehrhorn. Mr. Maskell has placed this as a synonym of A. 

 fimbr latum = Planchonia fimbriata ; but I have true (French) specimens 

 of the latter, kindly sent by Mr. Howard, 'and it is a totally different 

 thing. It is hardly necessary for me to say that I cannot in the least 

 agree with Mr. Maskell's proposed synonymy of the species oi Planchonia 

 or Asterolecanium. As several of the rejected species are my own, I do 

 not care to discuss the matter now, but will leave it to the judgment of 

 other coccidologists who may have occasion to examine the several forms. 

 In fact, Mr. Maskell himself (as I hear from him) is giving closer 

 attention to the matter, and will, I doubt not, eventually revise his 

 present classification. 



(v.) Dactylopius, section without lateral tufts. 



(12) Dactylopius virgatus, Ckll. This is a destructive species, 

 hitherto only known from Jamaica. Prof. Townsend has just discovered 

 it in numbers on a cactus and other plants at Brownsville, Texas. 

 Fortunately, it is there preyed upon by a Scymnus larva and a Chalcidid, 

 which Mr. Howard tells me will form a new genus of Bothriothoracini. 

 In Trinidad, Mr. Urich has found a Dactylopius on Croton, which I 

 cannot distinguish from D. virgatus, var. farinosus ; although, curiously, 

 it also seems identical with Mr. Newstead's D. ceri/erus, found on Croton 

 in India. If this is so, ceri/erus falls as a synonym of virgatus. No 

 more need be said now, as I believe the subject will hereafter be fully 

 discussed by Messrs. Townsend and Urich. 



(vi.) Various Diaspince. 



(13) Mytilaspis pomorum (Bouche'), In the mountains, at Moun- 

 tain View, California, on Cornus calif or ulcus. Sent by Mr. Ehrhorn. 

 The specimens show fewer glands in the groups than some from apple,
