206 THE CANADIAN ENTOMOLOGIST. 



in certain localities near Stillwater, Oklahoma, on Quercus nigra, and 

 occurs in other regions on various species of Quercus. The specie^ 

 is very variable in colour, size and markings, and it is possible that 

 more than one species is included in tlie description. Further study 

 of larval characters would be necessary to separate them. It seems to be 

 ferquent across the continent. I have it from Dr. J. A. Lintner, Albany, 

 N. Y.; Dr. John B. Smith, New Brunswick, N. J.; Mr. W. M. Scott, 

 Atlanta, Ga., and a large number of specimens from Stillwater, Okla. 

 Dr. L. O. Howard wrote me from Washington, D. C, under date 

 of Jan. 5, 1899, ^^^^^ t'l*^ same species bears their (U. S. Nat. Mus.) 

 numbers 722, 2404, 3706 and 7387, and bears a manuscript name. No. 

 1097 in collection Okla. Expt. Sta. 



The species is one or more of the forms that have passed under the 

 name of Kermes galliformis, Riley. Mr. Theo. Pergande kindly compared 

 specimens with type specimens of Kermes galliformis, Riley, and has 

 decided them to be very distinct. Dr. Riley's description is not available 

 to most entomologists of to-day, so I should like to record here what 

 he says of it : " Kermes, galliformis, n. sp. A new species of oak coccid 

 mistaken for a gall. An esteemed correspondent from Ohio (Dr. John 

 Waider) sends us what he supposed to be some kind of a gall which 

 he found at Iron Mountain, Mo., on twigs of Quercus palustris. 

 They are pretty, large, globular, or almost globular, objects fastened 

 to the twigs either singly or in clusters as we are accustomed to see 

 certain Cynipid galls. Their shining yellow surface is handsomely 

 variegated with light brown patches. The particular species sent by our 

 correspondent is undescribed, and may be characterized as follows : 

 Mature female scale, average length 5 mm. Subspherical, usually some- 

 what broader than long, and often with a broad shallow constriction 

 medio-dorsally. Attached by a broad, dark brown cut or excavation 

 which is covered by a beak anteriorly and notched anally, the brown 

 colour extending to a point above the notch. Polished and smooth. 

 Ground colour pale yellowish, appearing under lens minutely and evenly 

 specked with brown, more or less suffused or mottled with gray or 

 brown, the constriction when present generally dark. A series of about 

 seven irregular rows of black punctations running across the scale, 

 often connected by an irregular black line, and this again relieved 

 by white or pale yellow. The uppermost row distinct and constant." 



The form found at Stillwater, O. T., is considered typical of 

 K. trinotatus.
