CALISIUS.—CALISIOPSIS. 67 
Connexivum broad, punctulate ; each segment with a row of pallid granules along the apical and inner 
margins, and three prominent blunt teeth along the outer margin. The narrow space between the 
connexivum and scutellum set with five coarse pallid equidistant granules. Beneath closely, finely 
granulate. Rostrum very short, not nearly reaching the base of the head. 
Length 4, breadth 13 millim, 
Hab. Panama, Bugaba (Champion). 
Three examples. Closely allied to C. pallipes, Stal, from Brazil; but differing from 
it in the form of the antenne (C. pallipes being described as having joints 2-4 each a 
little longer than 1 and subequal in length) and other particulars. The connexivum 
has three prominent blunt teeth (two black and one ochraceous) on the outer border of 
each segment; viewed laterally, it is divided into two parts, a dorsal and ventral, each 
of which is similarly armed. 
CALISIOPSIS, n. gen. 
Head very broad, short, truncate behind, concave on each side between the eyes, which are large and promi- 
nent, the post-ocular portions short and dentiform, the antenniferous processes broad and bidentate at the 
apex; the apical process broad, as long as the rest of the head, reaching to the middle of the terminal joint, 
of the antenne, unemarginate at the tip; antenne very short, joints 1-3 exceedingly short and subequal 
in length, 4 ovate, stout, and a little longer than the others united; rostrum reaching the base of the 
head. Pronotum convex behind, bisinuate at the base, irregularly quadricarinate on the disc. Scutellum 
completely covering the elytra, extending to a little beyond the apex of the fifth abdominal segment, 
broadly triangularly raised in front and carinate down the middle thence to the apex. Connexivum 
broad, denticulate at the sides. Anterior cox moderately, the intermediate and hind coxe widely, 
separated. Venter rather convex. Legs very short, the femora moderately stout and unarmed. 
This genus includes a single species from the Isthmus of Panama. It differs from 
Calisius, Stal (= Aradosyrtis, Costa), in the very differently formed head and antenne. 
1. Calisiopsis ampliceps, n. sp. (Tab. V. figg. 4,4a,92; 48, antenna.) - 
©. Rather broad, oval, opaque, testaceous or ochraceous, the apical process of the head, the pronotum, and 
the sides of the connexivum mottled with fuscous, the scutellum pale, with an oblong mark at the middle 
of the sides and the raised basal portion blackish or fuscous, the body beneath ferrugineo-testaceous; the 
antenne and legs testaceous, the femora sometimes infuscate in the middle. Head (with the eyes) nearly 
as wide as the front of the pronotum, closely punctured, the sides, base, and apical process studded with 
coarse pallid granules and with two short rows of similar granules in the middle in front, together forming 
a V-shaped prominence, the post-ocular teeth extending outwards as far as the eyes; antenne glabrous, 
the apical joint granulate. Pronotum arcuately dilated at the sides behind and narrowing forwards, the 
lateral margins denticulate from about the middle forwards and crenulate thence to the base, the four 
carinz formed by rows of coarse granules, the interspaces closely punctured and sometimes with other 
scattered granules. Scutellum closely punctured, the median carina and margins each with a row of 
granules, the raised basal portion also studded with coarse pallid granules. Connexivum rugulosely 
punctured ; the apical margin of each segment studded with coarse pallid granules, the lateral margin 
with about four short teeth. The under surface rugulose at the sides, smoother in the middle. 
Length 22, breadth 13 millim. 
Hab. Panama, Bugaba, Tolé (Champion). 
Three specimens. The one from Tolé (without head) is smaller, and has the sides of
