interstitiis 9 et 10 perducta dein oblique ad suturam coniinuata ornatus, 

 versus apicem squamulis albidis simplicibus aspersus, subtus in medio 

 prosterni et mesosterni et in metasterno toto squamis plumosis albis densis- 

 simis, in ventre minus densis, indutus; rostro maris in submento dente 

 verticali armato; interstitiis elytrorum non punctulatis sed disperse rugulosis 

 et saepe subgranulatis; metasterno ad latera non granuloso; femoribus 

 dente non simplice sed intus minute denticulato et tibiis anticis intus 

 in medio laminato-extensis praecipue differt, Long 8,5 — 11 mm., lat. 

 2.5 — 3.7 mm. 



Head almost impunctate on the vertex, closely and confluently punctate 

 in front, with a very shallow median rounded impression. Rostrum elongate 

 cylindrical, straight or very slightly curved, somewhat dilated at the apex, 

 a little longer and more finely punctate in the $, in the cf the basal portion 

 as far as the antennae coarsely and confluently punctate, without any sulci 

 or carinae, the apical area with much finer separated punctures, and the 

 submentum with a distinct projecting tooth. Antennae inserted a little beyond 

 the middle of the rostrum in both sexes, the scape as long as the funicle; 

 joint 1 of the funicle as long as 2 + 3, joints 3 to 6 moniliform and slightly 

 transverse, 7 nearly as long as the club. Prothorax somewhat broader than 

 long, subparallel-sided from the base to the middle, then gradually narrowed, 

 with a constriction near the apex; the apical margin gently arcuate; the 

 dorsal outline almost straight, but sloping upwards from the dorsum 

 of the elytra at an angle of about 15^; covered throughout with shining 

 separated flattened tubercles, except the apical area which is feebly granulate. 

 Scute 11 um not enclosed by the suture, trapezoidal, depressed in front, 

 bare. Elytra cylindrical, not broader than the prothorax, with rows 

 of large oblong foveae as far as the postmedian squamose fascia and 

 becoming deeply sulcate behind this, and with a broad shallow transverse 

 impression at the base ; the intervals hardly broader than the punctures, 

 finely rugulose, with sparse minute setae, 1 — 5 subgranulate in the basal 

 half. Legs long, with rather sparse linear pale scales; the femora finely 

 rugulose and shallowly punctate, the tooth on the front pair large and 

 finely denticulate on its anterior edge; the tibiae with longitudinally 

 confluent punctures, the front pair with a rounded lamination in the middle 

 of the inner edge, the basal sinuation being deeper and shorter than the 

 apical. Sternum with the space between the front coxae only slightly 

 narrower than that between the mid coxae; the metasternum shallowly 

 punctate laterally, but the sculpture normally almost entirely hidden by the 

 dense scaling,

Mr. Kalshoven states that the larva of this species bores in the twigs 

 of cinchona trees.
