450 RHYNCHOPHORA. 
3. Microhyus longisetis, sp. n. 
Subovate, dull, black, the tip of the rostrum, the antenne, and tarsi ferruginous ; the vestiture ochreous, 
that on the prothorax mainly confined to the sides and to two vittee on the disc, and that on the elytra 
condensed into scattered spots, the upper surface also set with long, scattered, stout, erect, clubbed, 
fuscous sete, the legs setose. Head closely punctate. Prothorax a little broader than long, abruptly 
constricted and much narrowed in front, deeply bisinuate at the base; sparsely, finely punctate, except 
down the middle and along a space on each side of it, these portions of the surface being almost bare. 
Flytra much wider than the prothorax, constricted below the humeri and rapidly narrowing thence to 
the apex, the base sinuate ; striate, the striae with fine scattered punctures, the interstices alutaceous and 
somewhat convex, 3 and 5 slightly wider. Beneath opaque, very sparsely punctate. 
Length 21-24, breadth 14-1} millim. 
Hab. Guatemata, Senahu in Vera Paz, Capetillo (Champion). 
Two specimens. Narrower than J. hystrix, the prothorax with a space down the 
middle and another on each side of it almost impunctate, the elytral interstices 
somewhat convex. ‘The sete are very long. 
4, Microhyus erinaceus, sp. n. 
Ovate, dull, black or nigro-piceous, the tip of the rostrum, the antenne, and tarsi ferruginous; the vestiture 
sparse and fine, condensed into three vitte on the prothorax, fulvous, much darker on the elytra, the 
upper surface also set with moderately long, coarse, clubbed, blackish or fuscous sete, the legs setose. 
Head finely punctate. Prothorax transverse, constricted and narrowed in front, rounded at the sides 
anteriorly, deeply bisinuate at the base, finely, somewhat closely punctate. Elytra much wider than the 
prothorax, strongly sinuate at the base, subparallel in their basal third ; deeply striate, the strie rather 
coarsely punctate, the interstices moderately convex, rugulose, the alternate ones slightly wider. Beneath 
opaque, sparsely, finely punctate. 
Length 24-24, breadth 13 millim. 
Hab. Panama, Bugaba (Champion). 
Two specimens. Smaller than JM. hystrix, the prothorax shorter and less conical, 
the elytra relatively narrower, with the interstices not so flat and the striae deeper and 
more coarsely punctured, the setze less elongate. ‘The narrower strize and the broader 
elytral interstices, and the trivittate arrangement of the prothoracic vestiture, separate 
this species from the extremely closely allied MZ. setiger. 
5. Microhyus brevipes, sp. n. 
Subovate, rather shining, rufo-piceous, the tip of the rostrum, the antenne, and tarsi ferruginous; the 
vestiture fine, scattered, fulvous, the upper surface also set with moderately long, stout, clubbed, fuscous 
and pallid sete, the legs strongly setose. Head finely punctate. Prothorax a little broader than long, 
rounded at the sides posteriorly, narrowed and feebly constricted in front, deeply sinuate at the base ; 
closely punctate. Elytra much wider than the prothorax, subparallel anteriorly, strongly sinuate at the 
base; deeply punctate-striate, the interstices convex and almost equal in width, 3, 5, and 7 a little more 
raised than the others. Beneath opaque, finely punctate. Legs short. 
‘Length 2, breadth 1 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. Smaller and narrower than MV. erinaceus, rufo-piceous in colour,
