I have had the greatest difficulty in identifying this species, for it appears to be 
mixed with others in most collections; I believe it, however, to be a small species 
closely allied to E. binotata, but with the apex of the pronotal horn not dilated at 
the tip, if viewed from above, as is the case with the latter species. Say (teste 
Fairmaire) appears to have regarded it as probably a variety of E. binotata, but it 
appears to be distinct ; it is rightly determined by Signoret in the Vienna Museum 
collection. All the specimens I have seen come from the southern portion of Central 
America or from South America; the examples referred to it from more northern 
localities belong to £. binotata. 
2. Enchenopa binotata. (Tab. I. figg. 10,10, 104.) 
Membracis binotata, Say, in Long’s Second Exped. p. 801 (1824)*; Fairm. Ann. Soc. Ent. Fr. 
sér, 2, iv. p. 2517. 
Enchenopa binotata, Walk. List of Homopt. Ins. ii. p. 481°. 
Enchenopa bifusifera, Walk. List of Homopt. Ins., Suppl. p. 125 *. 
Hab. North America *, Quebec (Mus. Belg.), United States!3, New York 3,— 
Mexico, Jalisco (Schumann), Orizaba (Bilimek, in Mus. Vind. Ces.), Chilpancingo in 
Guerrero, Atoyac in Vera Cruz (H. H. Smith), Vera Cruz (Sallé+); Guatemaa, San 
Joaquin, San Juan, and San Gerdnimo, all in Vera Paz (Champion); Panama, Caldera 
(Champion). 
This insect appears to be widely distributed, from Quebec to the State of Panama, 
and to be one of the most abundant species of the genus; further south its place is 
gradually taken by HE. lanceolata, from which it may be known by the dilatation of the 
apex of the prothoracic horn, which is usually oblong and curved and bears a miniature 
resemblance to a swan’s neck and head. A specimen from San Gerdnimo is figured. 
8. Enchenopa minans. (Tab. I. figg. 11, 114.)
