622 PHYTOPHAGA. 



8. Monolepta panamensis. (Tab. xxxiv. fig. 23.) 



Pale fulvous; thorax minutely punctured, the sides piceous ; elytra convex, finely and closely punctured, the 

 suture, a transverse band before and another below the middle, black. 



Length 2 lines. 



Head with a few fine punctures at the vertex; the eyes very large and prominent ; the frontal tubercles trigo- 

 nate, distinctly raised ; antenna? fulvous, rather more than half the length of the body, the third joint 

 about one half longer than the second ; thorax transverse, slightly narrowed in front, the posterior margin 

 rounded, the surface very finely and closely punctured, with an obsolete transverse depression on each 

 side, the sides with a more or less distinct piceous longitudinal band; scutellum black; elytra more 

 distinctly punctured than the thorax, with a narrow transverse black band before and a similar one below 

 the middle, the suture anteriorly and the basal margin also narrowly black ; legs fulvous ; the first joint 

 of the posterior tarsi as long as half the tibise. 



Hob. Panama, Volean de Chiriqui (Champion). 



The thorax is sometimes devoid of the piceous lateral bands. M. panamensis cannot 

 be mistaken for Lwperodes dimidiaticornis, the latter being smaller and less robust, and 

 differing also in the colour of the antennae, in the first transverse band of the elytra 

 being placed nearer the base, and in the anterior coxal cavities being open. 



9. Monolepta fulvo-maculata. 



Black, the basal joints of the antennas and the legs fulvous ; thorax testaceous ; elytra extremely finely punc- 

 tured, black, an elongate spot at the shoulder and another near the apex of each, testaceous. 



Length 1J-2 lines. 



Head finely punctured and minutely granulate, the vertex black, the clypeus fulvous; labrum and palpi 

 piceous; antennas more than half the length of the body, fuscous, the three lower joints and also the 

 apical one fulvous, the third joint one half longer than the second ; thorax twice as broad as long, the 

 posterior margin slightly rounded, the surface scarcely visibly and very closely punctured, obsoletely 

 transversely depressed; scutellum black; elytra scarcely more distinctly punctured than the thorax, each 

 with an elongate testaceous spot at the shoulder and a narrower one near the apex, the latter extending 

 nearly to the suture ; legs fulvous. 



Eab. Mexico, Oaxaca (Salle). 



The coloration of this species is quite distinct from that of any of the allied forms. 



10. Monolepta triplagiata. 



Fulvous ; antennas, the apices of the femora, the tibise and tarsi, black ; thorax and elytra reddish-fulvous, the 



former finely punctured, the latter with two black spots at the base and a transverse band at the middle. 

 Length 1| line. 



Hab. Guatemala, San Juan in Vera Paz (Champion). 



The third joint of the antennae is but slightly longer though much more slender than 

 the second ; the thorax and the elytra are very closely and finely punctured ; the two 

 black spots on the latter are transversely placed immediately below the base, and the 

 central band is very narrow and does not quite reach the sutural nor the lateral margin. 

 The reddish colour of the upper surface and the elytral pattern separate this species 

 from its allies. A single specimen only was obtained.
