_ PANG.ZUS.—ECTINOPUS. 7 
The specimen figured is from Mexico ; it appears to be a well-marked form and con- 
stant in character. Besides the type in the British Museum, I have seen some six other 
specimens in collections, all received from Mexico. 
5. Pangeus discrepans. (Tab. II. fig. 19.) 
Pangeus discrepans, Uhler, Bull. U.S. Geol. & Geog. Surv. iii. p. 3867. 
Hab. Norru America, near Fort Cobb, Indian Territory; San Diego, California.— 
-Maxico ', Alvarez Mountains (Dr. Palmer) ; Nicaragua, Chontales (Janson). 
The specimen figured seems to agree well with Prof. Uhler’s description, and is from 
Alvarez Mountains, Mexico. It is most closely allied to P. (thus) curvipes, Dall., in 
structure, but lacks the transverse row of punctures near the anterior margin of 
pronotum. 
6. Pangeus impuncticollis (Sign. in litt.), n. sp. (Tab. III. fig. 7.) 
Above black, shining. Head broad; central lobe almost reaching anterior margin of head, which is reflexed ; 
coarsely wrinkled near lateral borders. Pronotum smooth, shining, impunctate. Scutellum with a 
catenulate row of coarse punctures at base, which also extend less regularly and rather more coarsely 
along two thirds the length of each lateral margin; a few coarse and scattered punctures on disk. Corium 
with a claval catenulate line of coarse punctures, and embolium also coarsely punctured; disk with a few 
fine and obscure punctures. Membrane fulvous at base, pitchy towards apex. Body beneath concolorous ; 
rostrum and anterior legs dark castaneous. Antenne castaneous; third joint faintly luteous at tip, 
remainder wanting. 
Long. 93 millim., lat. 53 millim. 
Hab. Mexico; Panama (coll. Sign.) 
The lateral pronotal borders are sparingly fringed with long hairs. This species is 
allied to P. discrepans, Uhler, but differs in the impunctate pronotum and different 
punctuation of the corium. | 
7. Pangeus rufifrons. 
Cydnus rufifrons, H.-S. Wanz. Ins. v. p. 97. fig. 547°; Stal, En. Hem. pt. 5, p. 26. 30. 
Pangeus rufifrons, Uhler, Bull. U.S. Geol. & Geog. Surv. iii. p. 384. 2%. 
Hab. Nortu America, Georgia 1, South Carolina ?.—Mezxico (Mus. Berol.). 
One specimen received from the Berlin Museum agrees with the typical figure and 
description, but varies in the colour being castaneous, thus being concolorous with the 
legs. The eyes are also pale luteous: 
| ECTINOPUS. 
Ectinopus, Dallas, List Hem. i. pp. 110, 121 (1851). 
This genus at present contains but one species, which has hitherto been found in 
» the Central-American and Amazonian subregions of the Neotropical Region. 
It is distinguished by the extreme length of the posterior tibiee, which are half the
