change is uniting these coal measures with the coals of Waikato 
and Drury,and with the Aotea and Waitemata series of Auckland 
into acretaceo-tertiary tormation. To this change Professor Hut- 
ton could not agree, tor he had always maintained that Dr. Hoch- 
‘stetter’s views were correct. But, however this may be, it is cer- 
tainly most remarkable that Dr. Hochstetter, in his short stay of 
only nine months, should have distinguished six out of the eight 
systems into which our rocks can be divided. 
On the suggestion of Mr. H. R. Webb, it was resolved that the 
President, together with Protessors von Haast and Hutton, should 
be requested to prepare and forward te Mrs, von Hochstetter a 
letter of condolence,

Capt. T. Broun. 
The author states :—‘‘In all the following species of Euplectus, 
the three basal abdominal segments, usually seen from above, are 
strongly marginated laterally and on the same plane; the fourth, 
about equally large, is more or less deflexed, andthe suture between 
the two apical ones is not distinctly visible. 
‘In a dissected specimen I found a supplementary basal segment, 
anterior to that referred to in description as the first dorsal seg- 
ment. In another, examined from below, this additional segment is 
as large as the others, with its middle portion projecting between 
the posterior coxe. In E. monticola, E. incomptus, and E. cereus, the 
extva basal segment is uncovered by the elytra, and bears numerous, 
excessively minute, brassy scales. In an example of E. tuberigerus 
(Part III, p. 17, “Man. N.Z. Coleop.”) the additional basal dorsal 
plate is wholly exposed, so that in it, it seems as if the fourth, not 
the thivd, visible dorsal segment is protuberant at the middle. 
These facts conclusively prove that the New Zealand Euplectini 
are provided with a vetvactile basal segment.”
