In this genus the posterior margin of the metasternum is rounded, the nervures of 
the membrane are numerous and reticulated, and the rostrum has the base strongly 
incrassated. Probably about twelve species really belong to this genus, all of which 
are Neotropical, with the exception of Spartocera diffusa, Say, which is a purely Nearctic 
form of the genus, unless Prof. Uhler (Bull. U. 8. Geol. & Geogr. Surv. ii. p. 291) is 
correct in considering it a synonym of S. cinnamomea, Hahn, in which case, however, 
Say’s name should take precedence. Hahn’s species, with this exception, has not been 
recorded north of the Brazilian subregion ; nor have I received a specimen from Central 
America, though Prof. Uhler writes that it inhabits Mexico. Again, Townend Glover 
(Ill. Ins. Ord. Hem. p. 68) considers S. diffusa a synonym of S. fusca, Thunb. If this 
is correct, the difficulty is removed, as S. fusca is a common Central-American form. 
As some error is here at least probable, I have not included Say’s insect either as a 
species or variety in this fauna. Two species have alone passed through my hands, 
which have been received from Central America. 
1. Spartocera granulata. (Tab. XIII. fig. 6.) 
Spartocera granulata, Stal, En. Hem. i. p. 178. 
Hab. Costa Rica (van Patten), Volcan de Irazu(Rogers); Panama(Boucard; coll. Dist.). 
The locality whence the type of this species was received is unknown. The Central- 
American specimens agree well with Stal’s description. In some of the Costa-Rican 
forms the colour of the pronotum is dark fuscous, a peculiarity not observed in those 
received from Panama, of which one is here figured. 
2. Spartocera fusca.
