Masatierra, i ex. found under a stone, 5 — 10 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.

Masatierra, 24 ex., found under bark of Aristotelia macqiii L'Herit,, 

 19. XII. 1916 and I, IV. 1917, and confined so far as I am aware to this 

 island, 



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 (1. 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
