25. Madecops (?) denticollis, Fairm. (?). 



Loc. Rodriguez: 1918,3 sipec'imeus (Snell and Thomasset). 



Without a comparison with specimens from Bourbon, I 

 am unable to say whether tlie form from Rodrijjuez is the 

 same as Fairraaire's denticollis or is a nearly allied species. 

 Fairmaire's description agrees, as far as it goes, rather well 

 with tlie present specimens, except that the first joint of 

 the antennae is obconic rather than " crasse clavatus,^' that 

 the prothorax is more transverse, not transversely wrinkled 

 behind [" postice leviter plicatulo *'), and that the elytra are 

 rounded at the apex. The specimens are very like Saperda 

 vulpina, Klug, which is said by AUuaud to resemble 

 Madecops denticollis. 



If M. denticollis really belongs to Madecops, then that 

 genus has nothing at all to do with the Mesosini, but is 

 most nearly allied to the Niphonini, from which it only 

 differs by having the head considerably distant from the 

 anterior coxae. Tlie eyes are emarginate, but not sub- 

 divided. 



MiMECYRiDA, gen. nov. (Velorinorum). 



Head short, not retractile; front transverse, broadly 

 concave between the antennary tubercles ; genaj short. 

 Eyes deeply emarginate, but not subdivided, coarsely 

 facetted ; their lower lobe subquadrate. Antennee some- 

 what longer than the body, broadly distant at base, 

 setaceous; first joint obconic, slightly flattened on under- 

 side; third joint much longer than the first and also longer 

 than the fourth, slightly curved ; the following joints 

 gradually decreasing in length. Prothorax short, trans- 

 verse, distinctly and rather broadly constricted at base ; 

 sides unarmed, but slightly convex in the middle ; apical 

 groove obsolete, strongly arcuate above ; a very small 

 tubercle on each side at the apical margin ; basal and apical 

 margins truncate. Scutellum subquadrate with the apex 

 truncate. Ehjtra subcylindrical, nearly parallel-sided ; 

 each rounded at apex with the sutural angle distinct ; 

 scutellar region somewhat elevated, posterior half with 

 longitudinal costse, humeral costa distinct from base. Legs 

 rather short; femora thickened towards apex with a fine 

 longitudinal line on each side, hind femora not reaching 

 the apex of the abdomen ; tibiae rather long, cylindrical, 

 intermediate tibiae entire ; first tarsal joint shorter than 

 the second and third united : claws divaricate. Acetabula
