BRACHYSPARTUS. | 265 
1. Brachyspartus ebeninus, sp. n. (Tab. VIII. fig. 11.) 
Sexus? Oblongus, cylindricus, nitidus, subglaber, antennis pedibusque ferrugineis; fronte concava, breviter 
pilosa; antennarum clava cheliformi, acuminata; prothorace antice rotundato, medio vix conspicue 
bituberculato, postice parallelo, dorso antice gradatim declivi, asperato, postice subimpunctato; elytris 
ad apicem obtusis, subtilissime punctatis, declivitate convexe subtruncata, parce pilosa. 
Long. 2°3 millim. 
Sex? Oblong, cylindric, shining, nearly glabrous, black, the antenne and legs ferruginous. Forehead 
concave, the impression shallow, punctured and thinly pubescent, with a median shining subimpressed 
line, more distinct near the mouth. Antennal scape short, moderately clubbed towards the apex, not 
flattened ; funiculus two-jointed, the second joint closely applied to the base of the club and indistinct ; 
club moderate in size, cheliform, the superior border being continuously rounded, the inferior border 
strongly sinuate; surfaces uniformly pubescent, without long cirri, the inner face subconcave, rather 
shining; sutures two, expressed on the upper border only and not apparently crossing the club. 
Prothorax rather longer than broad, subcircularly rounded in front, parallel-sided behind the middle, 
the base sub-bisinuate, bordered; surface with no median elevation and gradually declivous in front, the 
apex slightly rufescent, with two small erect tubercles visible from above and behind only; anterior third 
asperate with short elevations, the remainder shining, with very fine sparse punctuation. Scutellum 
triangular, shining. Elytra as wide as the prothorax and one-third longer, subtruncate at base, with 
subacute humeral angles, parallel-sided and not narrowed behind, inflexed posteriorly by rounded angles 
to the obtuse apical margin; surface cylindrical, strongly but not abruptly declivous behind, with 
indistinct rows of minute punctures; declivity flattish, margined below, with somewhat distincter 
punctuation and a few very fine seriate hairs. Underside black, thinly pubescent. Anterior tibie 
slender, obsoletely dentate ; posterior and middle tibia more strongly dentate. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. Owing to the impossibility of dissecting this unique example, it has 
been difficult accurately to determine the presence of a second joint in the antennal 
funiculus and the characters of the sutures on the club. It is possible that exami- 
nation of an antenna mounted in balsam would alter the account given. The insect has 
a decided resemblance to the male of Scolytoplatypus daimio, Blandf., from Japan, in 
form and the shape of the antenne. It is, however, smaller and radically distinct in 
generic characters. 
2. Brachyspartus barbatus, sp.n. (Tab. VIII. fig. 12, antenna.) 
Sexus? Oblongus, cylindricus, vix nitidus, subglaber, testaceus (fortasse immaturus) ; fronte ad oculos 
excavata, epistomate bifasciculato; antennarum clava rhombiformi; elytris lineato-punctatis, ad apicem 
obtusis, declivitate ad suturam haud late impressa, utrinque in callum trituberculatum elevata. 
Long. 2°4 millim. 
Sex? About the size of B. ebeninus, but slightly more robust, less shining, entirely testaceous, but apparently 
immature. Forehead excavate to the eyes, the cavity shining, glabrous, with a narrow median carina, 
the epistoma furnished on each side with a fasciculus of shining hair curled upwards into the frontal 
cavity ; eyes broad oval, emarginate ; antennal scape slender, the funiculus two-jointed, the club rounded 
lozenge-shape, the inferior margin more strongly rounded than the superior, shortly pubescent, with a 
few scattered longish hairs and two distinct subtransverse sutures. Prothorax oblong, rounded at the 
apex, the margin of which is not tuberculate, parallel-sided behind, truncate at base, which is not 
margined, the hind-angles rounded; disc ample, somewhat gibbous in the middle and more convex in 
front than in B. ebeninus, anteriorly rather finely granulate, posteriorly subimpunctate, minutely 
reticulate. Scutellum rather large, subtransverse, rounded triangular, shining. LElytra as wide as the 
prothorax and one-fourth longer, truncate at base, with obtusely-rounded humeral angles, parallel-sided
