EPISPHALES. . 37 
In the National collection at South Kensington there is a specimen labelled 
“ Arrhenodes rugicollis, Jekel MS.”; it is probably a female of this species. 
4. Episphales optatus, sp. n. (Tab. II. fig. 6, head and front of thorax, @ .) 
Niger, nitidus, prothorace fortiter rugoso, medio longitudinaliter levigato et canaliculato ; elytris multi-sulcatis, 
sulcis fortiter punctatis, interstitiis 3° 4°que flavo-lineatis. 
Long. 26 millim. 
Hab. Costa Rica (Van Patten). 
This is another very fine insect, of which we have received but one specimen—a 
female; it is allied to £. rugicollis, but abundantly distinct, the pronotum being 
smooth along the middle, and the punctures on the elytra not so large; hence the 
longitudinal interstices between the rows of punctures form regular coste, while the 
intervals between the punctures in each series are obsolete, so that the grooves are 
almost crenate rather than punctate. ‘The under surface of the head and metarostrum 
is densely rugose; this character distinguishes the species from all others of the 
genus except HL. rugicollis. 
5. Episphales facilis, sp. n. 
Piceus, prothorave subeenescente, opaco ; elytris flavo-signatis, multi-punctato-sulcatis ; tibiis rufis. 
Long. 17 millim. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (HZ. H. Smith). 
@. Head and prorostrum obscurely red, the former with a faint metallic tinge; 
metarostrum with a longitudinal impression; head with a similar impression on the 
vertex, the sides of this latter impression projecting somewhat behind. Antenne short, 
dull red, stout; terminal joint nearly twice as long as the one preceding, acuminate. 
Thorax quite dull, with an excessively fine channel on the middle of the posterior 
part. Elytra with very regular coarse sculpture, taking near the suture the form of 
grooves; externally is a series of rather large punctures; the groove next the suture 
impunctate; third interstice with two short distant yellow marks on the posterior part, 
fourth with two on the anterior part, seventh with a very short one behind the middle, 
eighth and ninth each with a very short one, forming together a small geminate mark 
behind the shoulder. Under surface of head and metarostrum dull, without definite 
sculpture. 
The two specimens quite agree. 
6. Episphales similis, sp. n. (Tab. IT. fig. 7, antenna.) 
Niger, prothorace subenescente, opaco; elytris flavo-lineatis, fortiter punctatis, juxta suturam multi-sulcatis. 
Long. 16 millim. 
Hab. Guatemata, San Geronimo and Purula in Vera Paz (Champion). 
Closely allied to #. facilis, but with the punctuation of the elytra less coarse, the
