484 RHYNCHOPHORA. 
the third interstice of each elytron), two on the disc of the prothorax and two at its apex, the prothorax 
with two oblong ochreous patches on the disc behind. Elytra small. Prothorax transverse, constricted 
and slightly narrowed in front, rounded at the apex; densely, finely punctate. Elytra one-half wider 
than the prothorax, parallel in their basal half; coarsely punctate-striate, the interstices narrow and 
convex, 3 a little widened, 1, 3, 5, and 7 setigerous, Beneath finely punctate. Legs rather slender, the 
femora unarmed. 
Length 24, breadth 1+ millim. 
Hab. GuatTEeMALA, Cerro Zunil (Champion). 
Iwo specimens, one of them immature. A very close ally of U. quadrifasciculatus, 
but with the elytra a little less produced at the apex, the sete shorter. 
8. Ulosominus nanus, sp. n. 
Oblong-ovate, narrow, rufo-piceous, the antenne and rostrum ferruginous, clothed with small ochreous scales 
intermixed with coarse, erect, clubbed sete, these latter arranged in an irregular series down each of the 
elytral interstices 1,3,5,and 7. Prothorax transverse, constricted and narrowed in front, densely punctate. 
Elytra a little wider than the prothorax, subparallel in their basal half; coarsely seriate-punctate, the 
punctures subquadrate, the interstices narrow. Legs rather stout, the femora unarmed. 
Length 2,%, breadth 14 millim. 
Hab. GuatemMaLa, Balheu in Vera Paz (Champion). 
One specimen. Very like U. quadrifasciculatus and U. zunilensis, but with the 
elytral sete scattered and the coarse seriate punctures not placed in distinct strie. 
4. Ulosominus quichensis, sp. n. 
Oblong-ovate, narrow, nigro-piceous, the antennew ferruginous; densely clothed with dark brown scales inter- 
mixed with short, stout, erect, clubbed sete, these latter arranged in a single series down each of the 
alternate elytral interstices 1, 3, 5, and 7. Head and rostrum densely punctate, the latter stout, 
smooth at the tip, the eyes small. Prothorax as long as broad, slightly narrowed and constricted in front, 
densely punctate. Elytra oblong-ovate, a little wider than the prothorax ; coarsely punctate-striate, the 
interstices narrow and convex. Beneath finely punctate; mesosternum broad. Legs short and rather 
slender, the femora unarmed. 
Length 2, breadth 4—% millim. 
Hab. Guaremata, Quiché Mountains 7000-9000 feet (Champion). 
Three specimens. This minute species may be distinguished by its long prothorax 
and the oblong-ovate, slightly wider elytra. The intermediate coxe are widely 
separated, and the prominent mesosternum is short and broad. The ventral segments 
1 and 2 are connate at the middle. 
5. Ulosominus triseriatus, sp.n. (Tab. XXIII. fig. 26.) 
Oblong-ovate, narrow, rufo-piceous, the antenne ferruginous ; thickly clothed with small brownish scales, 
intermixed with erect, clubbed sete, these latter becoming very long on the anterior part of the prothorax 
and also towards the apex of the elytra, the sete short and arranged in a close series along the interstices 
3, 5, and 7, and on the apical half of 1. Head and base of the rostrum densely, the rest of the latter 
sparsely, punctate ; eyes rather small, widely separated. Prothorax broader than long, narrowed and 
slightly constricted in front, densely punctate. Elytra a little wider than the prothorax, somewhat 
flattened near the suture, parallel in their basal half, and gradually narrowed thence to the apex ; closely
