448 RHYNCHOPHORA. 
4, Heatus vestitus, sp. n. 
Subovate, black, the tip of the rostrum and the apices of the tarsi reddish; the upper surface opaque, clothed 
with scattered narrow ferruginous scales, the elytra with semierect paler sete intermixed. Head with a 
few fine punctures, the eyes very large, contiguous above ; rostrum curved, rather slender, a little longer 
than the prothorax, depressed and slightly rugulose at the base, almost smooth in its outer half, the 
antenne inserted at the middle, the outer joints of the funiculus transverse. Prothorax transverse, 
abruptly narrowed in front, bisinuate at the base ; densely, rugulosely punctate. Elytra subcordate, more 
than one-half wider than the prothorax, slightly constricted below the rounded humeri ; seriate-punctate, 
the punctures oblong in shape and placed in shallow strie, the interstices 3, 5, and 7 narrowly and finely, 
and the others obsoletely, costate. Beneath coarsely punctate. Femora rather sharply unidentate. Tibi 
angularly dilated at the base externally, the intermediate pair almost straight on their outer edge thence 
to the tip. Tarsal claws with a very short tooth at the base. 
Length 4, breadth 2} millim. 
Hab. Guaremata, San Juan in Vera Paz (Champion). 
One specimen, no doubt a female. The comparatively slender, almost smooth 
rostrum, the very large, contiguous eyes, the non-carinate prothorax, the scattered 
rusty-red vestiture, in addition to the paler sete, the straighter intermediate tibie, and 
the feebly toothed tarsal claws, separate 4. vestitus from its allies. 
MICROHYUS. 
Microhyus, Leconte, Proc. Am. Phil. Soc. xv. p. 237 (1876). 
This genus, hitherto including a single species from the United States, is well 
represented in our region. ‘The various forms are all very small and separable from 
Conotrachelus by the simple claws. The funiculus is 7-jointed, the joints closely 
articulated and becoming wider outwards. The rostral canal is open behind. The 
mesosternum is hollowed between the widely separated intermediate coxa, and not 
raised at the sides in front. ‘The metasternum is short, and longitudinally swollen 
on each side between the intermediate and hind coxe, the episterna rather broad. 
The scutellum is very minute or hidden. The femoraare unarmed. The upper surface 
of the body and the legs are set with erect, clubbed or blunt sete, which are seriately 
arranged down each of the alternate elytral interstices. The Central-American species 
may be tabulated thus :— 
a. Elytra much wider than the prothorax, the latter transverse. 
a', Setze coarser and darker. 
a", Alternate elytral interstices tuberculate . . . . . . . « . montanus, sp. u. 
b", Alternate elytral interstices not tuberculate. 
a'", The finer vestiture of the elytra subfasciculate.
