BUPRESTID. 
DIADOXUS. 
D. Jiingi, sp. nov. Parvus; postice sat dilatatus ; supra niger, 
capite (basi excepta) viridi, prothoracis lateribus et disco 
(his longitudinaliter) et elytrorum maculis discoidalibus 
quaternis vittaque laterali antica testaceo-viribus ; subtus 
pedibusque [abdominis segmentis 2° ad apicem 3°-5° que totis 
(maculis quaternis flavis exceptis) rufis, tarsisque picescen- 
tibus, exceptis| viridibus ; capite rugulose punctulato ; pro- 
thorace leviter transverso, sparsius punctulato; elytris 
leviter striatis, striis punctulatis, interstitiis planis, apice 
acuminato ; segmento ventrali apicali ad latera angulata 
(parte intermedia late leviter emarginata) vel ad latera vix 
angulata (parte intermedia subbisinuata) ; antennis nigris. 
Long., 34-34 1. ; lat., 14-12 1. 
In colour and markings this species does not differ much from 
D. erythrurus, White, but it presents several structural distine- 
tions which certainly appear to be specific. It is very much 
smaller and considerably less narrow in proportion to its length, 
and its prothorax is shorter being by measurement distinctly 
wider than long. I was at first disposed to think it the male of 
D. erythrurus and the latter the female, but on careful examina- 
tion I am satisfied that I have before me both sexes of both 
species. In erythrurus the apical ventral segment is trispinose 
in both sexes, the middle spine in the male (2), however, being 
reduced to little more than a strong angulation of the outline ; 
while in the present insect the apical ventral segment is angular 
at its lateral margins (with the intermediate space feebly 
emarginate in outline) in one sex, and scarcely angular laterally 
(with the intermediate space feebly bisinuate) in the other sex. 
Mr. Jiing informs me that the present insect and D. erythrurus 
feed on different plants.

NATALIS. 
So many alterations have taken place in the genus Natalis 
since my former paper on it was published (Tr. Roy. Soc. S.A., 
1890) that it seems now desirable to furnish an amended tabula- 
lation of the species,—more particularly as the numerous speci- 
mens of the genus that I have examined have led me to the con- 
clusion that some of the characters made use of in the former 
tabulation were not well chosen. In the following notes some 
remarks on those characters will be found as well as on the 
original descriptions of some of the species. It unfortunately is
