Rhodobseims biundulatus 



(Tab. VI. figg. 14, 14 a, $ .) 





Elongate, subfusiform, opaque above, black, pruinose, the somewhat closely placed punctures each surrounded 

 by a denser, rounded, brownish-cinereous spot, the elytra with two angulate fascise (one before, the 

 other just beyond the middle, the broad intervening space appearing blacker than the rest of the surface) 

 formed by a similarly-coloured incrustation. Rostrum shorter than the pro thorax, stout, abruptly bowed 

 from the moderately widened, narrowly sulcate basal portion, closely punctate to near the tip, the 

 peduncle of the submentum angulate or with a minute prominence in front, the rather broad, outwardly- 

 widened antennal scape nearly reaching the apex. Prothorax slightly longer than broad, abruptly and 

 obliquely narrowed anteriorly and somewhat compressed at the sides towards the base, the base itself 

 feebly bisinuate, the disc transversely excavate posteriorly ; moderately closely punctate. Scutellum 

 elongate-triangular, narrow, hollowed down the middle. Elytra much wider than the prothorax, 

 narrowed from the rounded humeri, transversely depressed below the base and beyond the middle ; 

 finely punctate-striate, the interstices each with a row of scattered rather coarse punctures. Pygidium 

 conical, pilose at the tip. First ventral segment of the <J obsoletely grooved down the middle. Femora 

 fringed beneath with scattered hairs. 



Length U£-12 j, breadth 4-4|- millim. (<??.) 



Hab. Mexico (Salle, Flohr), Misantla in Vera Cruz (Huge).

specimens, the one with a fai 



first ventral segment assumed to be 





a male. Distinguished by the two angulate cinereous elytral fasciae, which are separated 

 by a blackish space; the excavate, anteriorly constricted prothorax; and the com- 

 paratively short, stout rostrum. The elytra are uneven, as in the larger and more 

 robust B. plicatus. 



14. Khodobaenus tenuiscapus, sp. n. (Tab. VI. figg. 15, 15 a, 6 .) 



Elongate, subfusiform, opaque above, black, greyish-pruinose, the somewhat closely-placed punctures each 

 surrounded by a denser brownish-cinereous dot, the elytra with a complete, rather broad, more or less 

 distinct black fascia just before the middle. Eostrum stout, about as long as the prothorax, abruptly bowed 

 inwards from the broad, closely punctate, narrowly sulcate basal portion, the apical portion compressed, 

 sparsely punctate in the <$ , and a little longer and almost smooth in the 5 , angulate towards the tip 

 beneath (as seen in profile) in both sexes, the peduncle of the submentum with a blunt tooth in front 

 in the $ . Scape of the antenna} long and slender, thickened towards the apex. Prothorax longer than 

 broad, conical, feebly bisinuate at the base, rather sparsely punctate. Scutellum elongate-triangular. 

 Elytra long, much wider than the prothorax, narrowing from the base, finely punctate-striate, the 

 interstices each with a row of rather coarse scattered punctures. Pygidium large, subcorneal, rounded 

 at the tip, sparsely punctate. Beneath very sparsely punctured ; ventral excavation of the 6 broad and 

 deep, extending far forwards along the metasternum, the corresponding space slightly hollowed in the £ . 

 Legs elongate ; femora fringed with long scattered hairs beneath. 



Length 10J-15, breadth 3f-5i millim. ( <$ $ .) 



Hab. Costa Rica, Irazu (Bogers), Azahar cle Cartago (Underwood). 



Three males and one female, varying in size and in the sculpture of the prothorax.
