LITHOCHARODES. 
Lithocharodes, Sharp, Trans. Ent. Soc. Lond. 1876, p. 204. 
This genus appears to be peculiar to the New World, where its species range from 
Mexico to Uruguay, the Central-American region being apparently their metropolis. 
Only one other species is known to me in addition to those here enumerated. 
1. Lithocharodes spinigera. 
Rufa, nitida; elytris dilute fuscis, pedibus testaceis; capite thoraceque sat crebre vix fortiter punctatis, linea 
mediali levigata ; elytris parce subtilius punctatis, prothoracis longitudine ; capite subtus parce haud 
subtiliter punctato. 
Long. 5-6 millim. 
Hab. GuateMALa, near the city (Champion). 
The head is oblong, rather narrow; the thorax also is slender, and the superior 
marginal line of the thorax exists in front, though very fine. The male has the hind 
margin of the last ventral plate marked with a deep angular excision on either side, 
and projects in the middle as a very acuminate tooth; the last dorsal plate is broad at 
the extremity, and truncate, being just perceptibly sinuate on each side; in the female 
the hind margin of each of these plates is simply rounded. 
A dozen examples have been found, showing very little variation ; these were captured 
on the sandy banks of the small streams at the bottom of the deep ravines or “ barrancas”’ 
on the outskirts of the city of Guatemala. 
2. Lithocharodes armata. 
Rufa, nitida; pedibus testaceis; capite thoraceque sat crebre fortiter punctatis, linea mediali laevigata ; elytris 
parce subtilius punctatis, prothoracis longitudine ; capite subtus parce fortiter punctato. 
Long. 5 millim. 
Hab. Nicaracva, Granada (Sal/é). 
This species is very closely allied to L. spinigera, but the punctuation is a little 
coarser, and the male characters a little different; the central projection or tooth of 
the last ventral plate is very acute, but there is only a slight emargination on each side 
of it; on the other hand, the sinuation of the last dorsal plate is slightly more distinct, 
and its angles rather more prominent. 
Only one example is present. 
3, Lithocharodes simillima. 
Rufa, nitida; pedibus testaceis; capite thoraceque linea mediali levigata, fortiter, illo crebrius hoc sparsim, 
punctatis ; elytris quam thorax brevioribus, parce punctatis ; capite subtus parce fortiter punctato. 
Long. 5} millim. 
Hab. Guaremata, Cahabon (Champion).
