abrupte clavatis, 5-11 linearibus, baud decrescentibus. 

 Thorax dimidiuru elytrorum a3quans, cyathiformis, antice 

 ovato - convexus, ante basin valde constrictus, ante 

 apicem autem paulo constrictus. Elytra planata, apice 

 rotunda to. Femora crassa, gradatim clavata : tarsi 

 articulo primo elongato, caeteris sequalibus. Pro- et 

 mesosterna inter coxas angustissima ; acetabula extua 

 clausa. 



Diphyrama singularis, n. sp. — Olivaceo-nigra, subtus 

 et pedibus (interdum autem antennis) castaneo-fuscis, 

 tomento sericeo^ griseo-argenteo, vestita; elytris fascia 

 angusta basali a humero ad humerum arcuata, alteraque 

 multo latiori pone medium^ per suturam ascendenti, 

 sericeo-nigra. 



Long. 34-6 lin. (J ? . 



Chontales ; many examples. A curious and pretty 

 Longicorn, closely allied to Epropetes latifascia, differing 

 by its long antennge with strongly clavate third and fourth 

 joints, by its thorax more abruptly constricted near the 

 base, and by the markings of the elytra. 



Listroptera aterrima, Germar, Ins. sp. nov. p. 497. — 

 A species of wide distribution from South 13razil to 

 Nicaragua. 



Dihammophora Chontalensis, n. sp. — Sublinearis, nigra, 

 opaca, thorace cylindrico, paulo insequali, aurantiaco, 

 opaco; elytris squamulis griseis minutis dense vestitis, 

 punctos fere obtegentibus, disco extus lineis duabus 

 elevatis. 



Long. 4 lin. (^. 



Very similar to D. nitidicoUis, but distinguished by the 

 absence of silky gloss on the thorax, and by the elytra 

 being clothed with minute griseous scales, which nearly 

 conceal the punctures ; the two exterior raised lines are 

 black. The antenna3 are rather longer than usual in this 

 genus, reaching at least to three-fourths the length of 

 the body. 



One example.
