INSECTA SAUNDERSIANA. 
macula are not so posterior, the distance between the base and the first 
being shorter, and that between the second and the apex longer; also there 
is a third macula near to the apex, generally obsolete in Pt. annulicornis . 
I must add that the antennae are longer, extending beyond the base of the 
elytra by more than the length of the apical joint of their club: they are 
also more slender. 
III. Genus TMBOTROPIS, Jekel. 
The species composing this genus are allied to Hypselotropis , and 
some of them (Phlceolragus prasinatus, Sch. — Ph. conicollis , Jekel MSS.) 
have the same green toraenlosity of the body and the four quadrangularly 
placed black maculae in the middle of the elytra. They, nevertheless, differ 
both from it and Ptychoderes , in having no appearance of longitudinal 
ridges at each side of the rostrum between the eyes and the antennal 
groove: this part is either subtubularly convex or somewhat flattened, 
being either smooth, punctate or rugose. The rostrum has its longitudinal 
impression more limited in width on the disc, and is more shallowly and 
angularly continued towards the forehead ; its median ridge is much less 
strongly indicated, often interrupted in the middle of its length, becoming 
more distinct on the forehead, which is narrow and convex as in Hypselo- 
tropis. The thorax is nearly shaped and depressed as in these genera, but 
its posterior carina varies; being in some as in Hypsel. ( Phlceotragus , 
Sch.) annulicornis (ex. gr. Tr. prasinatus, Sch.) ; in others it follows the same 
direction on the upper side, but it terminates sideways in the middle of 
the length ( pustulatus , F. Sch.; speciosus, Klug, Mus. Berol.); finally, 
in others, it is not more obliquely directed upwards to the sides of 
the disc than in Ptychoderes, but it js not interrupted in the middle, very 
highly raised, and very prominent sideways, where it acutely terminates, 
though very obsoietely and sinuately continued to the middle of the sides 
(conicollis , Jekel MSS.; punctulatus , Dupont MSS.) The elytra , more 
or less impressed longitudinally, and more or less—sometimes even not at 
all—callose behind, recal to mind the general shape of the elytra of these 
two genera. The legs are elongate and thinly but uniformly clothed, as in 
Hypselotropis.
