Psyche 
[September 
but since he arbitrarily assigned all Palaeozoic insects to 
that order, his system of classification is without phylo- 
genetic significance. Handlirsch, who, of course, had no 
real knowledge of the species, placed it in incertae sedis 
under the Palaeodictyoptera. I have removed the species 
from that order for two reasons: 1) the superimposed 
wings strongly indicate that the insect was neopterous; 
and 2) there is no convex anterior media, the division of 
the media being remote from the origin of M. The insect 
therefore seems most probably protorthopterous, though 
its family affiliation is not clear because of the poor preser- 
vation of the wing. I have provisionally placed it in the 
family Palaeocixiidae, since it shows some resemblance to 
Palaeocixius. 
Adlerzia froggatti Forel and Some New Synonymy 
(Hymenoptera : Formicxdae) — In another paper, now 
in press, 1 have discussed the confusion attendant on For- 
eFs description of Adlerzia, based on a stray worker of a 
single species and wrongly placed as a subgenus of Mono- 
morium. It has since been determined that two subsequent- 
ly described ants placed in different genera represent differ- 
ent castes of A. froggatti. The following synonymy is sug- 
gested here in order to avert proposal of a new name for 
Stenothorax McAreavey, which is preoccupied by Harris 
and by Agassiz : 
Adlerzia froggatti Forel 
Monomorium ( Adlerzia ) froggatti Forel, 1902, Rev. Suisse 
Zook, 10: 445-447, worker [minor] ; original description. 
Machomyrma silvestrii Emery, 1914, Boll. Lab. Zool. Porti- 
ci, 8 : 182, fig. 2, soldier ; new synonymy. 
Stenothorax katerinae McAreavey, 1949, Proc. Linn. Soc. 
N. S. Wales, 7 J : 3-4, figs. 7-16, worker major [ergatoid?] ; 
worker minor; new synonymy. 
Stenothorax McAreavey, nec Harris, nec Agassiz, with 
the genotype and sole species katerinae ( loc . cit.) becomes 
an absolute synonym of Adlerzia Forel by isogenotypy; 
new synonymy. — By William L. Brown, Jr., Museum of
