('ousiderable dillietdty has In'en experienced in determining tlie 
status of numerous series ol M itoIcthics Irom South-west Australia 
owing to the variations found in both soldiers and imagos li'om 
(litTei’ent colonies. Bractically no vai'iation has be('ii observaal in 
imagos from the same colony, and such diHerences as have* been 
d('tected in individuals from diHerent colonies, though constant, are 
by no means inaT'ked. In the soldier caste al.so there is remaikabk' 
agreement amongst individuals from the same colony, but variations 
do occur occasionally (e.g., a specimen with smaller head, shorter 
atid stouter froj)tal ])rocess ami narrower gula). Between individuals 
from dilTerent colonies, however, there is olteii, a very marked 
(lifTerence, whi(4i, in the absence ol imagos, might very reasonably 
be regarded as specific. Mr. ('lark, to whom I am imlebted for the 
material under discussion, on being apprised of the diiruadty, kindly 
made a s])ecial effort to obtain further series, with the result that 
about 45 colonies have been plac('d at my disposal, of which numbei 
about twenty include alate imagos or (pieens. 4'he balance com- 
prise soldiers and workers, or sohliers only, associated in most cases 
with species belonging to othei' genera- Hamilcmes oheimlis Silv., 
Uaviilernieti sp., Le/acoleme.s clarki Hill, L. occidmis, n. s])., and 
Liitervies apiocephahts Silv. and including several varieties oy races 
more or less distimt. (in the soldier caste) from those of which the 
imagos are known. In view of th(> fact that only slight diflerenc(>s 
have been obscwved in series of imagos tlu^ respective soldiers o 
which are more or less markcMlIy distinct, it has bc'cn c-onsidcncd 
advisable for the present to icgarcl thc> whole- group as being rc-lc-rabh- 
to a single spc-cic-s (4/. Lmepclriil Silv.) and to briefly dc-scribc- thc- 
more important varieties or races without dc-signating thc-in by
