MICROHYUS. 451 
the prothorax less constricted in front, the convex elytral interstices almost equal in 
width, the legs shorter. The sete are of about the same length in the two species. 
6. Microhyus angustatus, sp. n. 
Subovate, narrow, slightly shining, black or piceous, the tip of the rostrum, the antenne, and tarsi ferruginous ; 
the vestiture sparse, fine, fulvous, the upper surface also set with long, clubbed, erect, light and dark 
seta, the legs setose. Head closely punctate. Prothorax nearly as long as broad, narrowed and slightly 
constricted in front, feebly bisinuate at the base; closely punctate, the punctures not hidden by the 
vestiture. Elytra comparatively narrow, a little wider than the prothorax, subparallel at the base; 
deeply and rather coarsely punctate-striate, the interstices convex, the alternate ones rather more raised 
than the others. Beneath dull, closely, coarsely punctate, the punctuation becoming finer on the last three 
ventral segments. 
Length 14-2, breadth 1 millim. 
Hab. GuaTemaLa, Senahu in Vera Paz, Zapote (Champion). 
Six specimens, five of which are from Senahu; another, from Cerro Zunil, may 
belong here, but it has narrower strize and flatter elytral interstices. This very small 
species may be recognized by its comparatively narrow form, the convex elytral 
interstices, and the feebly bisinuate base of the prothorax. The sete are longer, 
coarser, and darker than in W/. pallidisetis. 
7. Microhyus pallidisetis, sp. n. 
Ovate, narrow, shining, rufo-piceous, the antenne, rostrum, and legs ferruginous; the vestiture very sparse, 
fine, fulvous, the upper surface also set with long, fine, erect, clubbed, pallid sete, the legs sparsely 
setose. Head finely punctate ; joints 2-7 of the funiculus short, closely articulated. Prothorax nearly 
as long as broad, narrowed and slightly constricted in front, feebly bisinuate at the base ; closely, finely 
punctate. Elytra a little wider than the prothorax, subparallel at the base; deeply striate, the stria 
somewhat coarsely punctured, the punctures becoming foveiform at the sides, the interstices narrow and 
equally convex throughout. Beneath opaque, sparsely, rather coarsely punctate. 
Length 1%, breadth 3 millim. 
Hab. Guatemata, Tamahu in Vera Paz (Champion). 
One specimen. The narrow shape, the rufo-piceous colour, the shining elytra, 
with narrow, convex interstices, and the uniformly pallid sete, distinguish this minute 
species. 
8. Microhyus minutissimus, sp. n. 
Oblong-ovate, narrow, dull, black, mottled with rufo-piceous, the base of the antenne, the tibie, and tarsi 
ferruginous ; sparsely clothed with narrow ochreous scales, which on the elytra are closely clustered 
on the dorsal elevations, and also set with widely scattered, short, erect, blunt sete. Head and rostrum 
very finely punctate, the latter smooth, bare, and shining in its outer half. Prothorax a little longer 
than broad, constricted and gradually narrowed towards the apex, very feebly bisinuate at the base, 
closely punctate. Scutellum not visible. Elytra oblong-ovate, a little wider in front than the pro- 
thorax, constricted and transversely depressed below the base, the humeri obtuse; deeply striate, the 
strie feebly punctate, the interstices convex, 3 with three oblong conspicuous prominences, 5 also here 
and there raised. Beneath dull, very finely, shallowly punctate. 
Length 14, breadth 1 millim.
