11. Eugnamptus cinctus, sp.n. (Tab. II. figg. 5,3; 6, 2.) 
Rufo-testaceus, setosus, antennis fuscis, clava nigra, elytris ad latera nigro-viridi cinctis ; prothorace crebrius 
fortiter punctato. 
Long. cum rostro 53-6 millim. 
Hab. Mexico, Zacualtipan in Hidalgo (£/dge). 
Var. elytris nigro-viridis, circa scutellum vage rufescentibus. 
Antenne with only moderately long club, the terminal joint slightly shorter than the 
tenth. Rostrum short, the head very finely punctate. Thorax coarsely and closely 
punctate. Elytra with regular series of rather fine and distant punctures, the inter- 
stices broad, flat, and with only an extremely fine, remote punctuation. 
We have received a good series of this species; the colour of the elytra is variable 
owing to the lateral cincture being developed to a greater or less extent, and sometimes 
nearly covering the surface ; the sexual disparity is very great, the male being a rather 
longer, more fragile insect, with much larger and more approximate eyes, and slightly 
shorter rostrum. | 
12. Kugnamptus longipes, sp. n. 
Longulus, testaceus, setosus, antennis valde elongatis, nigricantibus, basi fusco-testacea ; prothorace sat crebre 
et fortiter punctato ; elytris seriatim sat fortiter punctatis, interstitiis subtiliter seriatim punctatis. 
Long. 5-6 millim. 
Hab. GuateMata, Capetillo, Calderas (Champion). 
Var. elytris ex parte majore nigro-viridi-tinctis. 
This insect is very closely allied to E. cinctus, but is more elongate, has a consider- 
ably longer club to the antenne, and the lateral cincture of dark colour on the wing- 
cases is absent. The variety suffused with green is usually, if not always, of the female 
sex, and differs from the corresponding variety of H. cinctus in having the lateral margins 
of the elytra pale, the dark colour extending forwards from the apex. The distinctions 
of the sexes are much the same as in #. cinctus, with the exception that in the female 
of E. longipes the eyes are larger and less widely separated than they are in the corre- 
sponding sex of &. cinctus. 
Twelve examples have been received. A very mutilated specimen found in Mexico 
by Truqui may possibly be referable to this species. 
13. Hugnamptus tibialis, sp. n. 
Longulus, testaceus, breviter sctosus, minus nitidus, antennis valde elongatis; vertice prothoraceque densius 
punctatis; elytris seriatim profunde punctatis, interstitiis minus latis, convexis. 
Long. cum rostro 5 millim. 
Hab. Mexico, Oaxaca (fHége). 
g¢. Antenne very elongate, the club long and slender, unicolorous, the terminal joint
