Several examples of this very distinct species have been 

 sent home by Mr. Belt. 



Ptychodes Lecontei, Thomson, Rev. & Mag. Zool. 1856, 

 p. 477, pi. 24, f. 1. — Apparently a common insect in 

 Chontales. Originally described from Costa Hica.* 



Tceniotes scalaris, Fab. Ent. Syst. I. 2, p. 257 ; {T. su- 

 turalis, Thorns. Archiv. Ent. I. 172). — The Fabrician 

 description accords with the Mexican and Central Ameri- 

 can form of this insect, which Thomson has redescribed 

 as T. suturalis. The only difference from the South 

 American local form, is in the amount of spotting on the 

 elytra ; T. scalaris having the fewest spots, as indicated in 

 the Fabrician diagnosis, ''Elytra fusca, puncto medio 

 suturaque dentata albis.^' 



Tceniotes prceclarus, n. sp. — T. inquinato similis ; differt 

 colore nigro nee metallico, capite thorace et pectore 

 lateraliter late flavo-vittatis, elytrisque apice nuUo modo 

 armatis. T. inquinato paulo robustior et minus elongatus, 

 niger, pube griseo-fusca tenuiter vestitus, linea angusta 



* Add : — Ptychodes niveisparsis, n. sp.— Niger nitidus, elytris omnino 

 albo irroratis, apice prope suturam breviter siuuato-truncatis, angulo su- 

 turali spinoso, exteriori dentato; capite et thorace dorso lineis duabus 

 approximatis albis ; genis transversim albo-lineatis, et corpore toto ab 

 oculis usque ad anum late albo-vittata ; mesosterno tuberculo maguo, 

 antice producto.
