MONOLEPTA. 62 ^ 



the lateral margin of the latter pieeous; elytra closely and finely punctured, the interstices still more 

 finely punctate and slightly wrinkled, the extreme lateral margin pieeous. 

 Length 2 lines. 



Hob. Hondueas {Salle). 



This insect is closely allied to M. imitans and M. subrwgosa, but it seems to differ 

 from both in several particulars. M. hondurensis is larger and of more elongate 

 shape ; the head is finely granulate and punctured (when seen under a strong lens) ; 

 the clypeus has a very distinct central raised ridge, extending upwards between the 

 antennee (in M. subrugosa the clypeus is much more flattened and almost united with 

 the frontal tubercles) ; the antennae extend to about half the length of the body, the 

 first three joints are testaceous and the rest fuscous; the thorax is more transverse 

 than in the two allied species, and exceedingly finely punctured (the disc has the usual 

 transverse shallow groove) ; and the punctuation of the elytra consists of small and still 

 smaller punctures crowded together. Three specimens, agreeing entirely in the above 

 particulars. 



18. Monolepta bipartite (Tab. xxxiv. fig. 25.) 



Obscure fulvous; antennae black, the basal and the apical two joints fulvous; thorax extremely finely punc- 

 tured; elytra scarcely visibly punctate, black, this colour divided by a narrow transverse fulvous band. 



Length 1-1 1 line. . .. 



Head not visibly punctured; the frontal tubercles but slightly raised and nearly contiguous; tbe clypeus 

 flattened, without any central ridge; palpi pieeous; antenna as long as the body in the male, shorter in 

 the female, the three lower joints testaceous, the apical two joints fulvous, the apex of the terminal one 

 fuscous, tbe third joint in the male extremely small, smaUer than the second, in the female larger ; thorax 

 more than twice as broad as long, of usual shape, depressed on each side of the disc, the latter with some 

 fine irregularly distributed punctures, flavous or fulvous ; scutellum black; elytra convex subcylindrical, 

 very finely and closely punctured, black, the fulvous median band narrow, slightly widened at its middle, 

 and nearly extending to the sides ; below and the legs testaceous, the tibiae more or less fuscous. 



Eab. Panama, Bugaba, Volcan de Chiriqui, David, Caldera {Champion). 



This small species much resembles in coloration Luperodes dimidiaticornis ; but may 

 be known, apart from its different generic characters, by the colour of the antennee, 

 these organs always having the apical two joints fulvous. Many specimens.
