THE COCCID GENUS AULACASPIS. 59 



species of Juniperus. Aulacaspis hoisdiivalii v. maculata, Ckll., 

 becomes Diaspis boisdavalii v. maculata. Aidacaspis vdranda, 

 Ckll., becomes Diaspis miranda. Aidacaspis cattlei/ce, Ckll., 

 becomes Diaspis cattleijcB. These three are all American. Diaspis 

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

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

 bases of the lobes, as in Diaspidiotus, 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- 

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

 under Diaspis by authors : — 



Aidacaspis roses (Bouche). Europe. 



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

 no keel. 



Aidacaspis pentagona (Targ.). Probably native of -Japan or 

 China. 



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

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

 so many. 



Aidacaspis pcrsimilis (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. 



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

 carinate. 



Aidacaspis craivii (Ckll.). China. 



Aidacaspis craivii fidleri (Ckll.). South Africa. 



Diaspis zaniics 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 fagrcece. 



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).
