Hab. Mzxico 12 (Sallé), Omilteme in Guerrero 8000 feet (/7. H. Smith), Cuernavaca,

(Champion), Aceituno (Salvin). 
Eighteen specimens have been seen of this insect (including the type), the four from 
Omilteme having the body, elytra, and anterior femora much suffused with fuscous. 
Subfam. SAICINAA. 
This subfamily of Reduviide agrees with the Emesine in the absence of ocelli, but 
differs from it in the much less elongate anterior coxe. ‘The three known Tropical- 
American genera are all represented within our limits. 
SAICA. 
Saica, Amyot et Serville, Hist. Nat. Ins. Hémipt. p. 371 (1843); Stal, Hemipt. Fabr. i. p. 129, 
nota; Enum. Hemipt. i. p. 124, and iv. p. 91. 
This genus includes three known Tropical-American species *, all of which occur 
within our limits, whence two others are now added. Saica is easily recognizable by 
the curved and unarmed anterior tibie, the long pronotal and scutellar spines, the long 
intermediate and hind legs, and the setose (not spinose) anterior femora. These latter 
have a row of sete along their lower face—in some species regularly arranged, and in 
others broken up into clusters or fascicles,—and a second row of closely placed sete 
along their anterior edge. From the lower sete, as well as from those on the 
trochanters, a viscid substance is extruded by the insect (the sete being more or 
less stuck together in all the specimens examined), no doubt to assist it in capturing 
its prey.
