Hab. Panama, Volcan de Chiriqui (Champion). 
Of similar form and appearance to D. nigrella, which, however, has black legs, 
spined lateral thoracic tubercle, and differently sculptured elytra. Mr. Champion 
captured this and many other species of the genus by beating the withered leaves of 
fallen or felled trees in fresh clearings in the forests; the Distenie, as well as many 
other Longicornia, are fond of hiding in the curled-up leaves in the daytime, and 
probably sally forth only at night. 
5 (x). Distenia punctiventris. 
D. simplici affinissima, sed paullo minor et gracilior, antennis, palpis et pedibus fulvis elytrisque castaneis apice 
' fuscescentibus. Capite mox pone oculos prominentes constricto ; thorace sat angusto, dorso vix calloso, 
medio punctis nonnullis grossis, tuberculo laterali conico obtuso; elytris apice rotundatis sat crebre et 
grosse (versus suturam confuse, versus latera subseriatim) punctatis, prope apicem punctis paucioribus ; 
metasterno et ventris segmentis 1-3 grossissime sed discrete punctatis ; scapo gradatim modice clavato 
basi tenui, sparsim punctulato; femoribus paullo grossius clavatis.

Hab. Panama, Volcan de Chiriqui (Champion). 
Two examples. 
5(1). Distenia brevicornis. (Tab. XVII. fig. 18.) 
D. punctiventri simillima, differt tantum ventre fere levi, metasternoque multo sparsius punctato, Antennis 
fulvis, 2 quam corpus brevioribus ; pedibus fulvis, elytris castaneo-rufis, capite, thorace corporeque subtus 
nigris nitidis ; scapo breviori paullo grossius sed discrete punctulato. 
Long. 55 lin. 9. 
Hab. Mexico (Sallé). 
One female example, with the antenne considerably shorter than the elytra. Of 
D. punctiventris only the male is known; but the female of the very closely allied 
D. simplex has antenne quite as long as the body,
