164 Psyche [October 
fication of the Homoptera in the same masterly way in which the 
later Dr. Reuter has the Heteroptera. I add the following notes: 
Genus Stobaera Stal. 
Crawford unites concinna, minuta and affinis with tricarinata 
but I am by no means convinced. While closely related I still 
believe them distinct as pointed out by me in my report on the 
Florida Hemiptera. 
Genus Cochise Kirk. 
In a letter from Mr. Muir he has suggested to me that Cochise 
apacheanus Wirk. is a synonym of Bostera nasuta of Ball and I 
am inclined to think him right in this. Kirkaldy writes his descrip- 
tions in such a vague way it is impossible to form any mental 
picture of the object he is describing. For instance what does he 
mean when he says “lateral keels (of the pronotum) distant apically 
and basally, arising anteriorly at the inner margin of the eye, 
curving at an acute angle near the hind margin to meet the eye 
again’’? If one tries to draw such a carina on a Delphacid prono- 
tum he finds himself wandering aimlessly about, with two entirely 
different sets of carine as the final result. Probably the genus 
can only be located by a restudy of the type. 
Genus Achorotile Dahlb. 
It is likely that this genus does not occur in America. The 
specimens I formerly located as albosignata Dahlb., I now find 
to be the young of Megamelus notatus Germ. Achorotile foveata 
Spooner is a redescription of my Stobera 4-pustulata from Florida. 
Genus Jassideus Fieber. 
In Macrotomella the lateral pronotal keels are distinct and run 
to the hind margin and the form of the head is entirely different. 
Stiroma I also believe to be sufficiently distinct. Both of these 
genera have the keels of the head continued over the apex while 
in Jassideus they are obsolete there, a character Crawford accepts 
in Kormus. ; 
Genus Phyllodinus Van Duzee. 
Mr. Crawford names Jamaica as the locality for my nitens. It 
was from Florida and was described in my paper of 1909, not 
1907.
