Masatierra, I ex. found under a stone, 5—10O metres above sea level, 
20. XII. 1916. Found also in Chile. 
The specimen agrees with the description, though the elytra are more 
mottled than in the typical form; they also agree with the named examples 
in the British Museum.

Masatierra, 9 ex.; there are also 3 ex (WALKER) in the British Museum. 
Found also in Chile. 
There is considerable variability in this species, the examples found by 
Mr. Backstrom agreeing with the form in which the prothorax and elytra are 
concolorous. The author says that in this species the front dorsal pore is 
larger than the hind one, but I cannot detect any material difference.

Dr. JEANNEL in his Monograph refers to an example he had seen in the 
British Museum collection, probably a cotype, but, after a prolonged search, I 
have been unable to discover it, so that I have not been able, as I hoped, to 
make any comparison. The type, almost certainly from Masatierra, is probably 
in the Museum at Santiago.

REED’s account of this genus (I. c. p 62) is very incomplete. The ligula 
is dilated at apex, truncate, and bisetose; the paraglossae, which are glabrous, ~ 
are each as wide as the ligula, curve a little inwards and extend slightly 
beyond it, being separated from it on each side by a fairly wide notch. The 
lobes of the mentum are strongly rounded, pointed at apex, and not much 
longer than the tooth. The palpi are acuminate, only the extreme tip being 
truncate, joint 2 of the labials inwardly bisetose. On the head there is on 
each side one supraorbital pore and seta, and on the prothorax one lateral 
seta, the hind one missing, as usual among the Harpalini. The prosternal
