262 Rev. H. Clark’s Notes on the 
3. S. vicina, n. sp. 
Oblongo-ovalis, apice rotundata, elytris paulum dehiscentibus, 
flava, nigro-maculata: caput nigrum; thorax transversus, 
lateribus rotundatis sed haud ad apicem coarctis, margine 
antico paulum excavato, basi transversa, angulis posticis 
subrotundatis, sculptura ut in speciebus preecedentibus ; 
scutellum subcordatum, nigrum; elyira ad humeros thorace 
sublatiora, et deinde gradatim ampliora; a basi ad apicis 
regionem sunt sulci quatuor profundi lati, interstitiis rotun- 
datis ; horum externus profundissimus est post humeros, su- 
turalis et 24'S gequales, paralleli, tertius (minor subobsoletus) 
inter 2" et marginalem vix apparet; quoad colorem, elytra 
flava (pube densa et tenui flava vestita), vitta abbreviata 
ad suturam et basi laté nigris ; vitta abbreviata a sutura usque 
ad suleum primum minus quam elytrorum dimidium occupat ; 
apex quoque laté niger est ; antenn@ incrassatz, nigre ; pedes 
corpusque subtus quoque nigri. 
Long. corp. lin. 43; lat. lin. 2. 
S. vicina differs entirely from the preceding species by the 
sculpture of the elytra, although the mere patterns are in some 
degree similar ; instead of sharply defined and narrow ridges we 
have here rather longitudinal depressions, the intervals being 
rounded off; the flavous coloration of the insect is formed by very 
close and fine pubescence; the sutural marking of the elytra 
between the suture and the first channel extends nearly half-way 
to the apex, the medial termination of it being not abruptly 
transverse, but pointed; between this marking and the shoulders 
there are traces of other markings also, suggesting the possibility 
of the whole anterior part of the elytra being fuscous: the apical 
marking broadly extends from the margination to the suture, its 
upper margin being obliquely circular; the boundary line at the 
suture is at the distance of one-fifth of the whole elytra, and from 
that point extends in a generally semicircular direction till it 
reaches the margination at about the same distance from the apex. 
The form also (as well as the sculpture, and to some degree the 
pattern) of S. vicina differs from that of the preceding species; it 
is (being a much smaller insect) more parallel, more attenuate ; 
the sides of the elytra being manifestly more rounded. 
I have a single specimen from La Ferté’s Collection, received 
from Brazil ; in the Collection also of Mr. Baly.
