SACIUM. lil 
sculpture, disposition and shape of the elytral markings, and the enlarged fifth joint of 
its antenne. 
M. Sallé has quite recently sent me an example of this species for examination.

Long. corp. “— lin,=1-25-1'50 millim. 
Head yellow; antenne moderate, bright yellow. Thorax more or less flavescent, small, rather narrowed in 
front, the sides faintly margined, finely and distinctly punctured, with an impressed line within the basal 
margin; basal margin sinuated, with the angles nearly rectangular. Scutellum testaceous, small and 
rounded. Slytra rather short, attenuated towards the apex, closely and rather deeply punctured, broader 
and nearly twice longer than the thorax, widest near the shoulders, with a deeply impressed line on each 
side of the suture ; rufo-piceous, with a crescent-shaped mark within the apex, and a large round spot on 
the disc behind the middle, yellow; apex rounded. Abdomen more or less exposed, flavescent. Legs 
slender, bright yellow. Underparts pale castaneous or testaceous. 
Hab. Mexico! (Sallé) ; GuaTeMaLa, Zapote, Chacoj in Vera Paz (Champion). 
Differs from S. oberthiiri and S. latifasciatum in its smaller size, more attenuated 
form, and also in colour and sculpture. From S. mollinum, Lec., this very pretty 
species is distinguished by its much larger size, longer thorax, finer and closer punc- 
tuation, and by the markings of the elytra. A specimen from Zapote is figured. 
This insect is figured under the name of S. ocel/atum on our Plate. 
5. Sacium mexicanum.

Oblongum, modice convexum, nitidum, minutissime et remote punctatum, castaneum, vitta dilutiore in elytro 
utroque notatum; pronoto magno, antice ovaliter rotundato et reflexo, minutissime et remote punctato, 
interstitiis glabris, nitidis, linea basali profunda, margine basali sinuata angulis acutis; elytris quam 
pronotum haud latioribus, vix duplo longioribus, prope humeros latissimis, minutissime et sat confertim 
punctatis, interstitiis glabris, nitidis, lateribus marginatis, apicibus valde rotundatis; pygidio exserto, 
castaneo; pedibus rufescentibus. Long. corp. 5%; lin.=1-12 millim. 
Body oblong, moderately convex, shining, very minutely and remotely punctured, castaneous, with a pale 
longitudinal vitta on each elytron. Yhoraw large, ovally rounded, and reflexed in front, very minutely
