280 Mr. F. P. Pascoe’s List of the Longicornia 
only slightly produced, the anterior part of it very small, disk 
quadri-tuberculate, the central line replaced by a broad flattish 
callus anteriorly; scutellum triangular; elytra short, ovate, the 
dorsal keel very strongly marked and sending forth anteriorly a 
short branch directed towards the apex of the scutellum, the inter- 
mediate keel interrupted in the middle, and having at that point a 
whitish spot, apices rounded; body beneath and legs black, shining. 
Length 6 lines. | 
Differs from S. histrionicum in the more feeble armature of the 
prothorax, the ovate outline of the elytra, their prominent carinz 
and rounded apices, the smoothness of the scape, and other 
characters. There was only one specimen of this species. Very 
little stress can therefore be laid on its size, otherwise it is the 
smallest species of the genus. 
SrerrAsToMA STELLIO (De}j.). 
S. pubescens, albidum, fuscescente nebulosum; spina bifida 
laterali valde producta, dente antico minuto; tarsis anticis 
nigris, czeteris albidis, articulis duobus ultimis exceptis. 
Covered with a short dense whitish pubescence ; the mesial line 
confined to the vertex, cheeks below the eyes glabrous, black ; 
prothorax with the anterior marginal tooth short, the bifid lateral 
spine strongly produced, especially the anterior part of it, and 
pointing forwards; disk dark brownish, with thin strongly-raised 
smooth lines ; scutellum rounded behind ; elytra short, ovate, the 
dorsal keel not strongly marked, crowned with a line of small 
granules at the base, the intermediate and lateral keels still less 
strongly marked, all covered by the pubescence, sides brownish, 
between the base and middle a short oblique black line, behind the 
middle an angular line forming with its fellow, though not quite 
meeting on the suture, a W-shaped mark, along the suture a few 
black spots, apices obliquely truncate; body beneath black, the 
sides with a whitish pile; antenna a little longer than the body in 
the male, covered with a short greyish tomentum; legs greyish, 
the tibiz and tarsi varied with dark brown; the anterior tarsi 
black. 
Length 7 lines. 
This is, I believe, the Stctrastoma stellio of Dejean, and, so far 
as I am aware, it has not been published. The elytral carine are 
much less prominent than usual, forming in fact little more than 
angular lines, while those on the prothorax, and the bifid lateral 
tooth, are strongly developed.
