158 RHYNCHOPHORA. 
Oblong, piceous-red, covered with decumbent subsquamous hairs, cinereous-yellow, variegated with brown 
patches. Head oblong, blackish with mouth reddish; rostrum well-developed, carinate, impressed and 
shining (¢) with the side-margins elevated and the frontal pubescence denser, wider and less impressed 
(2) with the pubescence weak; antenne ferruginous with darker club. Prothorax transverse, 
constricted at apex, and widest a little behind the middle, the sides ( ¢) little rounded posteriorly, rather 
strongly about the middle and markedly constricted in front, (2 ) much less strongly rounded and con- 
stricted, flanks abruptly and obliquely inflexed, but not separated by an elevated margin from the dise ; 
above not very convex, subimpressed behind the apex, closely and finely punctured, and pubescent, with 
three brown vitte towards the base of darker semi-erect curved hairs, the outer vittes narrower and 
curved. Scutellum rounded, black, rugose. Elytra wider than the prothorax and twice as long, over- 
lapping its base, their basal margins rather strongly rounded but scarcely granulate, the sides subparallel 
to beyond the middle and thence obliquely rounded; red-brown with short decumbent pubescence 
tesselated with brown spots which form three or four irregular transverse vittee towards the apex, 
punctate-striate, the punctures large and deep, the strie not strongly impressed, the interstices slightly 
convex, with single series of rather long erect sete. Underside black, pubescent ; coxe and legs reddish, 
the anterior pair long. 
Hab. Panama, Volcan de Agua (Champion). 
One pair. A somewhat singular-looking insect, certainly very unlike the European 
Xylechinus pilosus, but not separated by any clear generic characters from the following 
species. The form of the head and prothorax recalls that of the very aberrant genus 
Hyorrhynchus, from Japan, which is peculiar in having the tibie destitute of armature. 
9. Xylechinus scabiosus, sp. n. 
Oblongus, piceo-niger, dense fusco-pilosus ; rostro carinato; prothorace transverso, antice constricto, dense 
rugose punctato, linea media indistincte carinata; elytris punctato-striatis, interstitiis convexis seriatim 
setosis, 1° et 3° ad apicem elevatis, 2° impresso, glabro. 
Long. 3 millim. 
Oblong, dull, covered with short fuscous hairs. Head black, front subconvex, finely and scantily pubescent ; 
rostrum wide, carinate, with an arcuate impression at base and a tubercle on either side of the carina. 
Prothorax transverse, narrowed towards apex, sides nearly straight to middle, then somewhat abruptly 
flexed ; lighter in middle of base and at apex, with close confluent punctuation, and a nearly effaced 
median carina, pubescence short, longer at sides, obscurely mottled. Scutellum small, rounded, rugose. 
Elytra rather wider than the prothorax and twice as long, separately rounded and crenate at base, 
subparallel to behind middle, thence rounded; surface pilose, with squamiform hairs, obscure brown, 
lighter in places, striate, the strie with strong rounded punctures ; interstices convex, tuberculate at 
base, each with a single series of short sete, Ist and 3rd elevated on the rather oblique declivity, 
2nd impressed and glabrous. Underside and legs black, the former scantily pubescent. 
Hab. Panama, Volcan de Agua (Champion). 
This species is separable from X. irrasus by the structure of the interstices at the 
apex of the elytra, the dull colour, and shorter vestiture. It bears a certain likeness 
to Hylastes subcostulatus. 
The four specimens show no marked sexual differences, and are probably all females. 
3. Xylechinus fuliginosus, sp. n. 
Oblongo-ovalis, opacus, fusco-pilosus, niger, antennis pedibusque piceis ; rostro perbrevi haud carinato; pro- 
thorace transverso ad apicem constricto, subsquamoso, granulato, linea media subelevata ; elytris dense
