Fianarantsoa, Antsianaka and Sea Alaotra; collected also by 
L. Humblot. 
The female is much distinguished by having the shoulder pro- 
longed into a costa as far as the depression so that the anterior 
portion of the disc is longitudinally divided into two portions, the 
transverse depression is posteriorly bounded by a strongly raised 
angulate costa which extends downwards below the middle and 
runds parallel with the lateral margin, besides this a small tubercle 
is also placed at the sides below the shoulders. Both sexes may 
therefore be readily distinguished from a species of Colasposoma by 
the appendiculate claws, the male by the structure of the legs and 
the female by that of the elyitra. Some specimens vary a good deal 
in several respects, the sides of the thorax are less rounded, 
straighter and the elytral golden stripes are almost absent, the 
posterior one is entirely wanting, another specimen is metallic blue 
above and the golden bands are replaced by purplish, some of the 
females are less deeply depressed below the base and the costæ 
much less distinct, but for all that, structural differences are absent, 
everything else agrees with the type and the intermediate degrees 
of sculpturing and coloration prove the species to be a very variable 
one. 
Syagrus Perroti Jacoby (Novit. Coleopt. 1895, p. 5). 
Dark fulvous, the head and thorax finely punctured, elytra strongly 
punctate-striate anteriorly, the apex nearly impunctale, the interstices 
at the sides longitudinally costate. 
Length : 3lines. 
Of elongate, parallel and subcylindrical shape, the head finely 
but not very closely punctured, with a short longitudinal groove at 
the middle, the clypeus iwice as broad as long, separated from the 
face, closely and distinctly punctured, eyes surrounded by a narrow 
sulcus, antennæ fulvous, the third and following joints elongate 
(the last three joints wanting), thorax one half broader than long, 
the sides moderately deflexed, slightly rounded, scarcely narrowed 
in front, posterior angles with a small tooth, the disc very finely 
and not very closely punctured with a nearly smooth central space, 
the anterior portion also very sparingly punctured, scutellum not 
longer than broad, its apex rounded; elytra wider at the base than 
the thorax, slightly transversely depressed below the base, very 
strongly punctate-striate anteriorly, the punctures of transverse 
shape, gradually diminishing in size towards the apex where they 
almost entirely disappear, the interstices at the sides strongly
