10 HEMIPTERA-HOMOPTERA. 
the Vienna Museum which are placed with it are so imperfect that it is almost 
impossible to identify them. 
There is a single specimen in our collection, referred to above as from Atoyac, 
which agrees with Fairmaire’s figure of the species (J. c. t. 4. fig. 32). I am inclined 
to think that EZ. minans is merely a smaller and darker form of £&. binotata. The 
Atoyac example is figured.

There is a specimen in our collection, from Bugaba, Panama, which must apparently 
be referred. to this species, but it has the pronotal horn a little longer and more 
curved, and the large yellow dorsal patch divided by a dark marking; at all events 
it appears too nearly allied to admit of a separate description. A specimen from 
Chiriqui is figured. 
5. Enchenopa sericea. (Tab. I. fig. 13.)

An example from Chiriqui is figured. 
6. Enchenopa rugosa, sp.n. (Tab. I. figg. 14, 14a.) 
Nigra; pronoto dense sat fortiter punctato, in cornu leviter curvatum producto, carinis lateralibus fortiter 
elevatis, lateribus rugosis ; tegminibus subhyalinis, fusco-brunneis ; pedibus nigris, tarsis testaceis. 
Black ; head subquadrate, with the anterior edge almost truncate, slightly sinuate at the sides; pronotum 
black, rather strongly punctured, with the lateral keels strongly marked and uneven, and with the sides, 
especially near shoulders, strongly rugose; a fine raised line runs underneath from the head to the apex 
of the pronotal horn, which is stout and slightly curved, and has the carine at the sides very distinct ; 
tegmina subhyaline, brownish, finely mottled, darker towards the base, punctured along the costa for 
about half their length ; legs black, with the tarsi testaceous. 
Long. 5 millim., cum tegm. 6 millim. 
fab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
This species superficially resembles E. monoceros, but differs in colour, sculpture, 
and shape of pronotal horn; and also in the colour of the tegmina, which in £. mono- 
ceros are unicolorous dark ferruginous, with a clear hyaline patch at the apex.
