Hab. Norta America, Texas }.—Mexico®; GuaremMaLa, Chacoj in Vera Paz (Cham- 
pion); Panama, Panama city, San Miguel in the Pearl Is. (Champion).—Braziu, Rio 
Janeiro!?; ANTILLES, Cuba 5. 
Of this widely distributed species three specimens, females, have been obtained 
within our limits, the one from Chacoj being discoloured and in a mutilated condition. 
They vary somewhat in the colour of the legs and antenne, and have the apex of each 
of the segments of the connexivum more or less pale. Costa’s specimen + was probably 
from Brazil. Dr. Bergroth (Wien. ent. Zeit. xiv. p. 168) has recorded A. falléni 
from Mexico. Prof. Uhler® adds Lower California and Mexico to the distribution 
of the Holarctic A. lugubris, Fallén. The specimen from Panama is figured.

‘The three known species of this genus are from Brazil, 8. Europe, and Australia 
respectively. The one now added is closely allied to the Brazilian insect, the type of 
Stal’s genus. 
1. Calisius ferox, n. sp. (Tab. V. figg. 2, 2a, 2; 26, antenna.) 
Q. Ovate, rather broad, opaque, ochraceous or obscure testaceous, the pronotum mottled with fuscous; the 
scutellum blackish or fuscous, with six pallid oblong spots—an oblique one at the sides below the base, 
one on each side of the median carina about the middle, and one below this extending to the margin, these 
latter sometimes connected ; the connexivum ferruginous or fusco-ferruginous, each segment with the 
granules along the apical and inner margins ochraceous or fusco-testaceous and the other marginal 
prominences black ; the legs and antenne testaceous, the apical joint of the latter fuscous; the under 
surface ferrugineo-testaceous. Head punctulate and closely studded with short, pallid, blunt spines, the 
antenniferous processes acute and divergent, the post-ocular spines extending outwards to beyond the eyes, 
the latter small; the apical process broad, as long as the rest of the head, emarginate at the tip; antenne 
short, joints’ 1 and 2 equal, 3 longer and more slender than 2, 4 ovate, about as long as 3. Pronotum sinuate 
at the sides before the middle, the posterior portion arcuately dilated, the base bisinuate; the four carine, 
sides, and apex studded with stout blunt spines, the interspaces punctulate. Scutellum closely, rather 
coarsely punctate, the raised basal portion, margins, and median carina studded with stout blunt spines.
