gined and scarcely rounded; basal margin much produced towards the scutellum, with the angles nearly 
rectangular. Scutellwm rather long, triangular. Hlytra subquadrate, scarcely broader but one half longer 
than the head and thorax, widest near the shoulders, marked with moderate-sized punctures in remote striae, 
the interstices alutaceous, more closely punctured towards the apex, with no humeral row of punctures ; 
yellow, ornamented on each elytron with a small black spot at the humeral angle, another before the 
middle on the suture, a large transverse reniform spot on the base, another in the middle, and another at 
the apex; sutural stria deeply punctured; sides margined and faintly rounded; extremities broad and 
moderately rounded. Abdomen long, yellow, with the bases of the segments narrowly black. Legs rather 
short, yellow. Underparis yellow. 
Hab. Panama, Bugaba (Champion). 
One example. 
Differs from the preceding species in its short, rounded form, smaller size, and 
ornamental colour.

Beocera, Erichson, Naturg. Ins. Deutschl. iii, p. 4 nota (1846). 
Antenne 11-jointed—1 long and rather robust, slightly recurved; 2 like the preceding, but straight; 3 short 
and slender, incrassate towards the apex; 4-8 each longer than the third, gradually incrassated ; 9-11 
incrassated equally on all sides, forming an elongate moniliform club. M axillary palpi slender, 4-jointed— 
1 very small; 2 and 3 rather long, nearly equal; 4 long and very acute. Labial palpi 3-jointed—1 long, 
cylindric; 2 smaller and shorter than the preceding; 3 small, acicular. Labrwm short and very broad, the 
sides rounded and broadly transparent, widely emarginate in front and minutely denticulate. Mandibles 
robust, much hooked at the apex, and furnished above the middle with a rather large, dentate appendage. 
Maxille robust, bilobed; outer lobe slightly dilated anteriorly, and furnished at the apex with strong, 
incurved sete; inner lobe large, robust, armed at the apex with long, incurved, setiform teeth. Mentum 
large, quadrate. Labiwm short and broad, slightly extending beyond the mentum. Lingua very large, 
transverse, much dilated and rounded at the sides, faintly emarginate in front, strengthened with a strong 
medial costa. Prosternum very small, carinated; episterna indistinct ; epimera minute; coxal cavities 
extending into the mesosternum. Mesosternum large; episterna very small, antehumeral; epimera long 
and very narrow, not extending to the coxal cavities. Metasternum moderate; episterna very broad, not 
extending to the coxee; epimera very large, much inflexed beyond the episterna. There are single rows 
of deep punctures on the anterior margin and on the sides of the metasternum, and on the basal margin of 
the first ventral segment. Venter composed of six segments—l1, 5, and 6 long, 2, 3, and 4 short. Legs 
moderate; tarsi 5-jointed—1 very long, 2, 3, and 4 shorter, nearly equal. Coxe: anterior large and 
prominent, separated by the carina; intermediate rather widely distant ; posterior less distant than the 
intermediate. 
This genus contains about a dozen described species, inhabiting North, Central, and 
South America, Europe, and New Zealand; five species are now recorded from Mexico 
or Central America. 
I am unable to identify either of the species before me with those described by 
Reitter.
