Brazilian Baring 109 



57 — Mandibles somewhat as in Gerceus, acuminate and prominent, straight 

 within, the left with feebly irregular edge, the right perfectly straight, both 

 with a feeble external tooth near the base, not so conspicuous as in Gerceus; 

 beak slender, smooth, cylindric; antennal club larger than in allied genera; 

 prosternum not impressed, the coxae moderately separated; femora rather 

 inflated; body closely clothed throughout. [Type F. duplex nov.] 



Forandia 



Mandibles straight within and even, but obtusely bilobed at apex; beak thin, 

 cylindric; antennae long, slender, the club peculiar, widest behind the middle, 

 thence gradually tapering, the basal segment much less pubescent; anterior 

 coxa? widely separated, the prosternum with two spines in the male, which 

 are separated by a very deep circular pit; body oblong-ovoidal, coarsely 

 sculptured and opaque, with large prothorax and very sparse inconspicuous 

 vestiture. [Type M. conifer nov.] Melampius 



Mandibles and antennae somewhat as in Gerceus, the former straight within and 

 having a sharp and prominent external tooth behind the middle, the latter 

 with the second, as well as the first, funicular joint elongate, the club moder- 

 ate, oval; body much more abbreviated and oval than in Gerceus; beak 

 moderately long, generally much flattened apically; prosternum without 

 transverse constriction or longitudinal impression, the scales radiating from 

 a central point, spinose or unarmed in the male; coxae moderately separated. 

 [Type G. bellulus nov.] Brachygerseus 



Mandibles subquadrate, with the inner straight edges even, having externally an 

 obtuse latero-apical tooth on each 5$ 



Mandibles with the inner edge very even, but in form they are curved outwardly, 

 sharply pointed and come in mutual contact when close only at base 59 



Mandibles with straight inner edge, which is generally even, becoming minutely 

 irregular in some genera, the tips usually rather sharply pointed, the outer 

 edges evenly oblique throughout the length 60 



58 — Body oval, with close and even, conspicuous vestiture; beak slender, cylin- 

 dric, joining the head without trace of transverse impression, as also in the 

 three preceding genera; prosternum flat, the coxae moderately separated; 

 antennal club elongate, pointed; femora not inflated. [Type F. carinulata 

 nov.] Forandiopsis 



Body narrower and rhomboidal, sparsely and much less conspicuously, though 

 evenly, squamulose; beak very slender except basally; antennae rather long, 

 with an abrupt and moderate club; prosternum flat, the coxae moderately 

 separated; femora slender; scutellum canaliculate. [Type C. mundula nov.] 



Centrinaspidia 



59 — Body as in Centrinaspis in habitus and vestiture, the latter on the elytra 

 also suggestive of Gerceus; prosternum transversely sulcate anteriorly, not 

 spinose in the male, the coxae moderately separated; legs slender; size very 

 small. [Type M. delicatula nov.] Microbaridia 



60 — Mandibles very even and straight within. Body more or less rhombic-oval, 

 with plentiful vestiture, very varied in design; beak rather slender, arcuate; 

 basal joint of the antennal funicle generally almost equal to the next three 

 combined, the second joint not elongate and but little shorter than the first, 

 as it is in Gerceus, where also the mandibles differ in having an external 

 basal tooth; prosternum not much modified; anterior coxae well separated, 

 the prosternum with or without two always very moderate spines in the 

 male. [Type Centrinus perscillus Gyll.] Gerceus Champion nee Pascoe; 

 Linogerceus Csy Centrinaspis 



Mandibles slightly irregular on their inner edges, though never definitely dentate.

61 — Basal segment of the antennal club very long, constituting two-thirds the
