In adenostomce the femur is very stout ; length i iS, breadth 64. 



The E. quercus studied was found by Mr. Quaintance on Qiierciis 

 aquatica, at Lake City, Florida, ]nn. 12. 



Eriecoccus Tinsleyi, Ckll., n. sp., was found by Prof. J. D. Tinsley, 

 April 30th, 1898, on roots oi Atriplex canescens, close to the Agricultural 

 College at Mesilla Park, New Mexico. The sac is 4 mm. long, of the 

 ordinary form and texture of the genus ; yellowish-white. Female 

 removed from ovisac plump, 3 mm. long, nearly 2 broad, not tapering 

 behind, delicately and very thinly pubescent, pale brown with a purple 

 tinge, two purplish dorsal bands faintly indicated. Legs and antennae 

 light brown. Antennae sometimes with 6, sometimes with 7, segments, as 

 above. The ? , placed in K. H. O., immediately turns brilliant crimson. 



Larva pale sage green, naked. Immature 9 purplish-gray, quite 

 bristly with white filaments, or it may be better to say, thinly but con- 

 spicuously beset with short white bristles. Eggs pale lemon yellow. 

 Allied to E. dubius, Ckll. 



Lecanium pubescens^ Ehrhorn, is a Eulecaniiim related to L. quercifex. 

 Fitch, but differing in the smaller size, and the details of the legs and 

 antennae. Under a high power the skin is seen to be minutely tessellate, 

 in the manner usual in the subgenus. 



L. Crawii, Ehrh., is also a EtiUcanium. It has a good deal of 

 superficial resemblance to L. nigrofasciatum, Pergande, ined., being of 

 about the same size and shape, though of a different colour. 



Z. ventrale, Ehrh., is related to L. aa(tni?iatum, Sign., but differs in 

 the longer tarsus.
