nence. The question then arises, Are the distinctions surrounding the 
fourth-lobe position of specific moment V In some genera they would 
not be. In Parlatoria all species are closely related, and hence dis- 
tinctive structural characteristics, though slight, are of greater weight 
than in genera where distinctions are more marked. The presence of 
tlie fourth lobe, rudimentary, with papillar termination, then, should 
differentiate the species P. peryandei from the species P. proteus 
with its fourth rudimentary lobe showing iilates extending beyond its 
caudal margin. 
NOTES AND CORRIGIENDA. 
Part 1. 
Aii)yidiotus obscurus Comstock as recorded was represented by only a few 
individuals upon one tree. I have since (October, 1899) found two black oak 
trees quite generally infested on both trunk and limbs. These trees are in a 
forest near Holton, Jackson county, Kansas. 
On page 4, and wherever it occurs thereafter, the specific term ancyclun 
should be ancylus. 
Part II. 
Lecanium canadense Ckll. Occurred sparsely when found at time of col- 
lection, April, 1898. Last year the same conditions existed. This season it 
appears to be abundant upon elms in Lawrence and vicinity; in some cases 
assembled in clusters. I have found a species, alike in form, size, and color upon 
hickory, a suggestion for further observations upon the status of caryai and 
canadense. 
Lccaniuni cockcrelU Hunter. This species has been found on plum in 
Nebraska ( Bruner MSS.) I have found it on hickory this season (May ) near Law- 
rence. The scale on hickory was well covered with a pruinose coating. 
Lecanium rnaclura'. being preoccupied, the term Lccaniuni aurantiacuin 
is now offered in substitution. 
Measurements of length and breadth of bodies of scales contain thereafter 
the abbreviation , which should be nun.
