"Kermes pubescens Bogue. Female scale spheroidal, 3.5 mm. in 

 diameter, 3 high, pointed and grooved beneath; covered all over with 

 short straggling pubescence. Color rather light brown, with more or 

 less obscure and suffused dark brown bands marking the obsolete 

 segments. Surface shining, with minute concolorous specks but no 

 dark spots or pits." Original description from the Canadian Entomolo- 

 gist, xxx, p. 172 (1900). 



The larvae of K. pubescens differ from the larvae of any other 

 known species, by having six rows of short conical spines and short 

 caudal setae. The body is narrower and longer and more attenuated 

 posteriorly. In the larvae of K. pubescens and K. ceriferus, the sixth 

 antennal segment is longer than the third. 



Remarks: This species has been found plentifully at Mi- 

 nerva Park, eight miles north of Columbus, on Q. macrocarpa. 

 Although there is a Red Oak {Q. rnbrum) adjacent, there was 

 not a specimen of K. pubescens on it.

K. trinotatu-'^ Bogue, Can. Ent., xxxii, p. 205 (1900). 



K. trinolatus Quaint. «&: Scott, Cocc. Am., Dec. iii-iv, No. 4 (1901). 



"Kermes trinotatus, n. sp. Female scale variable in size, averag- 

 ing about 5.5 mm. long, 6 mm. wide, and 4.5 mm. high; rounded above, 

 somewhat flattened behind, convex beneath, front turned down into a 

 more or less beak-like prominence; median groove obscure or broad 

 and shallow; color varies from bright argillaceous to dull gray; surface 

 uniform, more or less conspicuously speckled with black; segmentation 

 obscurely or plainly marked with dark spots. When the median groove 

 is present, it is crossed with more or less dark lines showing the seg- 

 mentation. There is a rounded dark spot on each side of the front, 

 and an elongated dark blotch extending for a short distance above 

 and below the anal opening; hence the specific apellation.
