The following descriptions of 4 new genera, 26 new species, and 

 3 varieties are the results of a study of the material of this sub- 

 family of the Cerambycidae from the West Indies contained in the 

 collection of the United States National Museum. In connection 

 with this study material from the American Museum of Natural 

 History has been examined. The descriptions of the new species 

 received from the American Museum (with the exception of one), 

 have been published in a paper issued by that institution.^ 



LIOSYNAPHAETA, new genus 



Mandibles moderately large and rather thick at base. Head broad, 

 feebly concave between the antenna! tubercles, the front wider than 

 long, and the cheeks rather short. Antennae shorter than body in 

 female, slightly longer than body in male, and rather strongly 

 ciliate beneath; first joint moderately robust, with a distinct open 

 cicatrix at apex, subequal in length to the third joint, which is 

 slightly longer than the fourth, the following joints gradually di- 

 minishing in length, with the last joint feebly bent near apex in the 

 male. Eyes large, rather coarsely granulated, and nearly divided, 

 the lower lobes as long as wide. Pronotimi wider than long, uneven 

 on disk, and tuberculate at the sides. Scutellum somewhat tri- 

 angular and broadly rounded behind. Elytra rather short, broad, 

 feebly convex above, without lateral carinae, and with the humeri 

 strongly developed. Legs moderately long, and subequal in length; 

 femora gradually enlarged near middle; intermediate tibiae not 

 grooved; tarsi short, the anterior pair slightly broader than the 

 middle and posterior ones, and the claws divaricate. Mesosternum 

 horizontal, arcuately emarginate posteriorly, and vertical in front, 

 with the anterior angle projecting; intermediate coxal cavities open. 

 Prosternal process rather narrow between the coxae, strongly arcuate, 

 and nearly vertical posteriorly.
