Numerous examples, some of which have been presented to us by Signor Solari. 

 This insect is so like an Anthonomid that it might readily be passed over as such ; the 



more approximate eyes and the produced posterior angles of the second ventral 

 segment, however, distinguish it at a glance. T. minor is perhaps nearest related to 



KM'ZZtM. which wants the dark undulate elytral fascia?. The rostrum is more

Four additional species of this genus, from Nicaragua, have been sent us by Sig 



iri. A second specimen of 8. tessellata, described from a single M 



Sol 





example, has since been found 



mixe 



the Barids : it was taken 



by myself at Tamahu, Guatemala. Another specimen of S. rotundata, from Bu

All these insects have the funiculus 6-jointed, and the elytra 



separately rounded at the apex, leaving the pygidium more
