THE COCCID GENUS AULACASPIS. 59 



sjjecies of Juniper us. Aulacaspis hnisdiivalii v. maculata, Ckll., 

 becomes Diaspis boisduvalii v. maculata. Aulacaspis viiranda, 

 Ckll., becomes Diaspis miranda. Aulacaspis cattlej/ce, CklL, 

 becomes Diaspis cattleyce. These three are all American. Diaspis 

 piricola, Del Guercio, appears to be certainly palfearctic, yet it 

 is not an Aulacaspis. But it has the club-shaped glands at the 

 bases of the lobes, as in Diaspidiotns, and I think it is related 

 thereto rather than to Diaspis. It may stand as Epidiaspis 

 piricola, using in a generic sense the subgeneric name already 

 applied to it. (' Suppt. Check-list of Coccidse,' p. 398.) Aida- 

 casjns will contain at least the following, all described or listed 

 under Diaspis by authors : — 



Aidacaspis rosce (Bouche). Europe. 



Aidacaspis fagrcece (Green). Ceylon. The male scale has 

 no keel. 



Aulacaspis pentagona (Targ.). Probably native of Japan or 

 China. 



Aulacaspis auranticolor (Ckll.). Japan. The first (caudad) 

 row of dorsal glands consists of only eight, the second has hardly 

 so many. 



Aulacaspis persimilis (Ckll.)- Mexico; but so close to penta- 

 gona that it is doubtless originally from the same region, and 

 was taken to Mexico on cultivated plants. It is possibly only a 

 variety of pentagona. 



Aulacaspis loranthi (Green). Ceylon. Male scale tri- 

 carinate. 



Aulacaspis crawii (Ckll.). China. 



Aulacaspis crawii fulleri (Ckll.). South Africa. 



Diaspis zamics and Poliaspis cycadis are of unknown origin, 

 having been found hitherto on cultivated plants only, mainly in 

 hothouses. But, judging from their affinities as shown by the 

 glands, it seems likely that the first came from tropical America, 

 and the second from the tropics of the Old World, where it finds 

 a reasonably close ally in Aidacaspis fagnecs. 



I will add a word about Mr. Newstead's treatment of Parla- 

 toria. I have regarded P. pergandei as a variety of proteus, but 

 I must now agree with Mr, Newstead that it is a valid species. 

 Further, I think P. proteus v. crotonis (of which Mr. Newstead 

 gives a beautiful plate) is also a good species, to be called Parla- 

 toria crotonis (Douglas).
