WoMERSLEY—MICROTROMBIDIINAE OF AUSTRALIA AND NEW GUINEA 339 
the dorsal setae Canesivini says ‘di orani et i squammette discoidali vestite di 
spine’', which appears to agree entirely with the above. The only eharaeters in 
which there is a slight difference are the front tarsi and metatarsi, of which Canes- 
trini cives the first as twice as long as the second. Im the new specimens the ratio 
is 4:3. flealso states that the erista is posteriorly bifid, which is doubtful.

A second specimen of this interesting species was collected at Bardon, 
Queensland, in Angust, 1948 (N.B.T.). 
Comparison with the type from Kangaroo Is., South Australia, shows that 
they are the same but that the drawings previously given, especially of the dorsal 
setae are not all that eould be desired, Fresh figures derived from the Queens- 
land specimen are therefore given in this paper. The dorsal setae are the shape of 
aswan’s head with a distinet beak and long eiliations (not as previously figured), 
On careful examination, however, the setae are seen to consist of 4 thin seale, of 
which the edges are strongly eurved under to form a helmet-like structure with a 
relatively small opening ventrally, The leg setae are more elongate and foliute but 
still showing the ventral folding.

This species was described from Auckland, New Zealand, as a doubtful 
Euthrombiem for it lacks the posterior dorsal plate. It is now placed in the new 
genus Toleotrambidium. 
As there were some shh errors in the original description and the dorsal 
setae were not sufficiently deserihed the following notes and fresh figures are now 
given. 
The palpal tibia externally carries » slender spine arising from near the base 
of (he palpal tarsus. The front tarsi of the unique type now measure 435 lone by 
180» hich, giving a ratio of 2:4, and the metatarsus is 360. long, giving a ratio of 
tarsus to metatarsus of 1-3. The dorsal setae are up to 50m long (not 120) as 
previonsly givert) and lie like closely adpressed scales; they are about 14 as wide 
asx lone, laminate, with strongly meurved margins, but not giving quite such a 
helmet-like appearance ag in the two preceding species; they are dark brown m 
colour and eiliated on the lateral margins (ef. fig. 29 D). Ventrally the setae ore 
shorter, fo 25, more hyaline and pointed but still showing the folding; on the legs 
they are similar, but reaching 40: in length (ef, fiz, 29 BH),

This species was originally described by Canestrini from Minsehhafen, New 
Guinea and later recorded by Berlese with move details and figures of the palp, 
front tarsus and metatarsus, dorsal setae and specialized setae from legs from 
Tijompea and Buitenzorg in Java,
