504 SEEEICOENIA. 



7. Ludius tropicalis. 



Elongate, rather broad, slightly shining ; castaneous- or pitchy-brown, the legs fusco-testaeeous ; somewhat 

 thickly clothed with short, fine, decumbent, fulvous or fulvo-cinereous pubescence. Head closely, coarsely 

 punctate ; antenna? extending very little beyond the hind angles of the prothorax, rather slender, joint 3 

 nearly twice as long as 2, and slightly shorter than 4, 11 appendiculate. Prothorax convex, as long as 

 broad, the sides subparallel to the middle and rounded thence to the apex, the anterior half of the 

 marginal carina not visible from above ; the hind angles long and sharply, obliquely carinate ; the surface 

 closely, somewhat coarsely punctate. Elytra from two and two-thirds to three times the length of the 

 prothorax, slightly rounded at the sides, narrowing from about the basal third, conjointly rounded at the 

 apex ; rugulose and closely, finely punctate, subgranulate at the base, the sutural stria distinct, the others 

 obsolete or faintly indicated. Beneath thickly and finely, the prosternum sparsely and more coarsely, 

 punctured ; prosternal process extended in the plane of the prosternum to the ante-apical tooth ; intercoxal 

 portion of the mesosternum V-shaped, gradually declivous ; posterior coxal plates broadly and subangularly 

 dilated opposite the point of insertion of the femora. 



Length 14-16, breadth 4-4| millim. ( $ .) 



Ilab. Guatemala, Senahu in Vera Paz (Champion) ; Panama, Volcan de Chiriqui 

 (Champion). 



Two specimens : the one from Chiriqui is a female, and the other is probably a male. 

 The Senahu example differs from the one from Chiriqui in having the thorax less 

 densely punctured, and the elytra more elongate, with the strise (the sutural one excepted) 

 obsolete. Allied to L. subopacus, but separable from it, and the other species here 

 enumerated, by the more elongate third antennal joint, this joint nearly equalling the 

 fourth. L. tropicalis is also broader and more robust than the female of L. subopacus, 

 in this respect approaching L. isthmicus, from which it may be known by the denser 

 punctuation of the upper surface, as well as by the structure of the antennae. 



8. Ludius rubicundus. 



Ludius rubicundus, Cand. Elat. Nouv. v. p. 58 (1893) \ 



" Brunneo-ferrugineus, pube longiuscula, fulva, minus dense vestitus ; prothorace longitudine parum latiore, 

 trapezoideo, sequaliter punctato, disco antice sub-biimpresso, angulis posticis acute dentatis * ; elytris 

 depressis, ultra medium parallelis, punctato-striatis, basi granulatis. — Long. 14, lat. 4 millim." 



Hab. Mexico 1 . 



Dr. Candeze has kindly forwarded his type ( $ ) of this species for examination. 

 Amongst the Central- American species, L. rubicundus most nearly resembles L. meri- 

 danus, from which it may be known by its more depressed form, the somewhat 

 trapezoidal thorax, the rather coarsely punctate-striate elytra, the structure of the 

 sterna, &c. The prosternal process is gradually declivous behind the coxae; the 

 intercoxal portion of the mesosternum is V-shaped and declivous ; the third joint of 

 the antennas is short, a little longer than the second, the two together as long as the 

 fourth. The diagnosis is insufficient for the purposes of identification. 



* Evidently a mistake for " carinatis."
