Cryptophyllaspis Riibsaameni, n. sp. — $ . Orange, oblong, caudal 

 end sunken, overlapped at the sides by lobiform projections ; no 

 circumgenital glands ; anal orifice broad-oval, about 1 7 //. long, and 

 distant about 39 /x from the bases of the median lobes ; lobes and 

 squames formed just as in C. ocacltus and of the general type of 

 Aspidiotus cya?iophylli ; three pairs of lobes, not even the median ones 

 darkened in the least ; median lobes slightly notched on each side ; 

 squames narrow and pointed, strongly fringed ; beyond the third lobe are 

 three double squames, each having the appearance of two squames united 

 at the base; interlobular incisions with thickened edges, of the Diaspidiotus 

 type ; two rows of dorsal glands, not very numerous, on each side of the 

 caudal end ; spines small.

NOTES ON MR. LYMAN'S PAPERS. 



BY A. RADCLIFFE GROTE, HILDESHEIM, GERMANY. 



I was much interested by Mr. Lyman's careful paper on a species of 

 Gortyna, boring in burdock. If aerata, Lyman, is a good American 

 species it should have an alternative food plant, since the burdock is 

 imported from Europe. From Mr. Lyman's detailed statements, the 

 distinction from necopina is assured. The differentiation from nitela is 

 not so clearly given. 



With regard to nitela, Mr. Lyman is quite correct, that Guene'e first 

 describes nebris and then nitela ; and in my catalogue of 1874 I give the 

 two as distinct species in the above order of their description. But in my 

 Buffalo Check List of 1875 J P lace nitela first ; and in 1882 I retain this 

 sequence and record nebris as a variety of nitela. But I am not agreed 

 with Mr. Lyman that nebris, the white-spotted type, represents the 

 original form of the species. I think the white filling in of the ordinary 

 spots a specialization, therefore a variat : on from the original form of the 

 species. The normal Gortynid ornamentation is probably that shown by
