intermixed with white, becoming sparse on a broad transverse space on the disc of the prothorax behind, 
the elytra conspicuously fasciculate with white and with the humeri similarly coloured, the femora 
annulate. Head densely punctate; rostrum feebly curved, one-half longer than the prothorax, rather 
stout, rugulose, and feebly tricarinate in its basal third, and then abruptly narrowed and quite smooth to 
the apex, the antenne inserted at one-fourth from the base, the scape comparatively short, joint 2 of the 
funiculus slightly shorter than 1. Prothorax strongly transverse, abruptly narrowed and constricted in 
front, deeply bisinuate at the base, the sides almost parallel behind; densely, rugulosely punctate, 
obsoletely carinate towards the apex. Elytra narrowing from about the basal fourth, slightly constricted 
beneath the humeri, which are rounded ; coarsely seriate-punctate, the interstices closely rugulose, 3, 5, 
7, and 9 sharply costate throughout, 10 also with a short ridge at the base. Intermediate coxe rather 
narrowly separated, the short intercoxal portion of the mesosternum slightly nodose on each side 
anteriorly. Ventral segments very sparsely, finely punctate. Legs short and stout; femora strongly 
clavate, the anterior pair feebly, and the others acutely, unidentate ; tarsal claws with a long tooth. 
Length 42, breadth 24 millim. ( 2.) 
Hab. Panama, Bugaba (Champion). 
One example. Near C. subulatus, but much broader, thé prothorax more transverse, 
the rostrum (¢) abruptly narrowed from near the base, the elytra conspicuously 
fasciculate with white, the mesosternum slightly holowed and not at all protuberant 
in front, the anterior femora feebly dentate. 
30. Conotrachelus alboplagiatus, sp.n. (Tab. XVIII. figg. 25, 25a.) 
Subovate, robust, rather dull, nigro-piceous, the antenne and the tips of the tarsi obscure ferruginous ; 
the vestiture coarse and rather close, fulvous, slightly intermixed with ochreous and white, that of the 
scutellum dense and entirely white, the elytra with a very broad, common, dense white patch (truncate 
in front, and sinuous at the sides) extending from the middle to the apex, the prothorax with a faint, 
sinuous, condensed, fulvous line on each side of the disc; the clothing of the under surface very sparse, 
white and fulvous intermixed, the femora with an ochreous or whitish ring. Head closely punctate, 
transversely depressed in front; rostrum moderately stout, curved, very little longer than the prothorax, 
squamose, rugulosely punctate, and feebly tricarinate, sparsely, finely punctate and bare at the tip, 
the antenne inserted at about one-third from the apex, joint 2 of the funiculus shorter than 1. Pro- 
thorax transverse, abruptly narrowed and constricted in front, the sides subangularly dilated at the 
middle and parallel at the base, the latter deeply bisinuate ; densely, finely, rugulosely punctate and 
incompletely carinate. Elytra broad, rather long, obliquely constricted beneath the prominent, obtuse 
humeri, narrowing from the basal third; seriate-punctate, the interstices closely rugulose, 3, 5, 7, and 9 
strongly costate, the ridge on 3 and 5 twice, and that on 7 once, broadly and abruptly interrupted, the 
median elevation on 3 greatly raised, slightly divergent, and lamelliform, and the subapical one vertical 
behind, 10 with a short ridge at the base, its apex dentiform. Prosternum with a prominent tuber- 
culiform elevation behind each anterior coxa. Mesosternum a little depressed between the coxa, and 
raised on each side, in front. Ventral segments very sparsely, finely punctate. Legs stout; femora 
clavate, unidentate ; tarsal claws with a short tooth. 
Length 7, breadth 3} millim. (2 ?) 
Hab. GvateMaLa, Cerro Zunil, Pacific slope (Champion). 
One specimen. Larger and more robust than the Mexican C. albosiqnatus, the 
prothorax more transverse, feebly carinate, and without a dense oblique white line on 
each side, the vestiture of the scutellum white, the white patch on the elytra extending 
to the apex, the tarsal claws with a shorter tooth. ‘The prothoracic epimera are 
obliquely raised, appearing strongly tuberculate when the insect is viewed from the side.
