LITHOCHARODES. 493 
sat crebre punctatis, linea mediali levigata; elytris thoracis longitudine, fere impunctatis; capite subtus 
fortiter punctato, evidenterque setosello. 
Long. 54 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
This species differs from ZL. fuscipennis in its rather smaller size, less vivid colour, 
and the more evident punctuation of the head and thorax. The unique individual is, I 
believe, a male, although there is nothing to indicate the sex, except that the terminal 
dorsal plate is quite truncate. 
8. Lithocharodes gracilis. 
Gracilis, nitida, rufa ; elytris fuscis, apice testaceo, abdomine sepius apicem versus plus minusve infuscato ; capite 
thoraceque sat crebre et sat fortiter punctatis, linea mediali levigata; elytris thoracis longitudine, parce 
obsoleteque punctatis ; capite subtus tantum anterius fortiter punctato. 
Long. 44 millim. 
Hab. Nicaracua, Chinandega (Sallé); Panama, Tolé, Pefia Blanca 3000 to 4000 feet, 
Bugaba (Champion). 
Very closely allied to L. fuscipennis, but considerably smaller, not so brightly 
coloured, and with the punctuation less obsolete. I see no sexual distinctions. Seven 
individuals have been found; the one from Nicaragua is in bad preservation, and may 
possibly be another species, 
9. Lithocharodes sordida. 
Gracilis, nitida, rufo-picea ; elytris dilute fuscis; capite thoraceque fortiter sat crebre punctatis, linea mediali 
levigata ; elytris thoracis longitudine, subtiliter punctatis; capite subtus parce fortiter punctato, nitido. 
Long. 5 millim. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
One example, probably a female; the tubular aperture at the extremity of the last 
segment being small, and the hind margin of the ventral plate rounded, that of the 
dorsal plate truncate. 
10. Lithocharodes puncticeps. 
‘Gracilis, nitida ; elytris fuscis, apice pedibusque testaceis, abdomine pectoreque fuscis; capite oblongo, anterius 
haud angustato, linea mediali levigata minus discreta; thorace gracili, anterius latiore, fortiter sat crebre 
punctato ; elytris thoracis longitudine, subtiliter punctatis ; capite subtus crebre fortiter punctato. 
‘Long. 5 millim. 
Hab. Mexico, Cordova (Sallé), Jalapa (Hége). 
This and the three following species form a group distinguished by the greater 
punctuation of the head. I have seen only four examples of L. puncticeps, two of 
which are very fragmentary; in one sex, presumed to be the male, the last ventral 
plate is produced in the middle so as to form there a rather indistinct broad, somewhat 
rounded, angle; the corresponding dorsal plate is slightly emarginate in the middle.
