INSECTA SAUNDERS1ANA. 
This large and fine species is about the size of the largest specimens 
of Slen. fulvitarsis; it is very close in outline, convexity and depression 
of the elytra to Sien. longulus , but proportionally broader. Its thorax is 
the least conical of any species known by me, the posterior lobe of its sides 
is regularly semicircularly, the anterior is widely and very obtusely 
rounded : the elytra are abbreviated as in Sten. brunnescem , and hardly 
more angustate posteriorly: the colour of the tomentosity of the middle of 
the thorax and the ordinary common patch of the disc of the elytra, is of a 
fine dense ochreous hue ou the latter, but nebulous, pale and rare on the 
former; the black macula filling the lateral emargination of the dorsal 
patch is of a fine blackish and very dense, widely extended laterally: the 
first joint of the tarsi is densely, the second less fulvous-spongiose; its 
place is at the beginning of the second section, before Sten. longulus , 
in consideration of its large size, though nearer to Sten. brunnescens , in 
the shape of the elytra ; by its thorax much less conically narrowed ante¬ 
riorly, it is easily distinguished from all the other species. 
There are four insects described by M. Blanchard, in Gay’s Hist. 
Natur. de Chile, under the generic appellation of Stenocerus , none of which 
are allied to this highly homogeneous genus. 
One, Sten. minutus , Blchd., loc. cit. Zool. v. p. 298, No. 2, is a 
minute insect of the size and shape of Tropideres undulatus , with which, 
in the form of the antennae and rostrum, and in its eyes small, round, 
semiglobose, lateral, not extending on the forehead, which is broader than 
the base of the rostrum ; it must be arranged close to Enedreytes, Sch. 
The second, Sten. asperatus, Blclid., loc. cit. Zool. v. p. 298, No. 1, 
close to the preceding in the character of its antennae, rostrum and 
eyes, but nearly double the size, and having the elytra tuberculated. It 
resembles Tropideres sepicola , which, like Trop. undulatus , has no other 
resemblance with the remaining European Tropideres , in which the 
“ eyes are large, flattish, nearly entirely placed on the forehead, which 
is much narrowed by them, especially towards the rostrum,’’ than the 
minuteness of the size. 
The last two species, Sten. signatipes, Blchd. (Zool. v. p. 299, No. 4) 
and Sten. tuberculosus, Blchd. (Zool. v. p. 299, No. 3, pi. 22, fig. 2) should 
naturally be placed near Ischnocerus , of which they have the rostrum and 
moderate sized lateral eyes, but they are generically distinguished by their 
having the antennas shorter and much thicker in both sexes, those of the 
male reaching only a little beyond the middle of the elytra in the most
