112 LONGICORNIA. 
Group ATAXTINI. 
Lacordaire’s “groupe” Ataxiides includes a small number of genera having “divergent” 
(é. é. subparallel) tarsal claws, like the Apomecynini, but differing from them and other 
groups in the much larger and more prominent eyes and narrower and shorter forehead. 
The antenne are more or less elongate, with long and distinctly separated joints, and the 
thorax is in general furnished with lateral tubercles. I propose to include in it the 
“proupe” Ptéropliides of the ‘Genera, and the genera Epectasis, Amphicneia, and 
Aletretia, which have been hitherto placed in widely different groups. 
As far as at present known, the Ataxiini ate confined to the American continent, some 
of the genera being peculiar to Brazil. | 
PARYSATIS. 
Parysatis, Thomson, Physis, ii. p. 118; Lacordaire, Gen. Col. ix. p. 599. 
Esthlogena (partim), Bates, Ann. & Mag. Nat. Hist. ser. 3, xvii. p. 290. 
Lacordaire omits the chief character which distinguishes this from the closely-allied 
genus Esthlogena—namely, the acute exterior apical angle and the narrow cicatrice of 
the antennal scape, a structural feature which did not escape Thomson. The genus 
is distributed throughout Tropical America from South Brazil to Mexico. Of the 
Esthlogene described by me from the Amazons and South Brazil the following belong 
to it—L. sulcata, mucronata, linearis, aud obtusa. 
1. Parysatis rufitarsis. 
Valde elongata, castaneo-fusca, dense erecte pilosa pilisque decumbentibus griseis maculatim vestita; antenna- 
rum articulis basi griseis ; tarsis fulvo-rufis ; capite thoraceque grosse discrete punctatis, hoc linea irre- 
gulari dorsali brevi ; elytris punctulato-striatis, apice utrinque flexuoso-truncato, angulo suturali rotundato, 
exteriori dentiformi, acuto; tibiis ut in P. swlcata haud dilatatis ; mesosterno antice late concaro levi. 
Long. 6 lin. . . 
Hab. Nicaraeva, Chontales (Belt). 
Similar to P. sulcata and P. mucronata ; differing from the former by its narrower form 
and different colours, and from the latter, with which it agrees in general form, by the 
undilated tibie. 
2. Parysatis flavescens. 
P. nigritarsis (Thoms.) proxime affinis. Modice elongata, breviter erecte pilosa tomentoque flavescente vestita ; 
pedibus rufescentibus, geniculis tarsisque nigris; thorace grosse discrete punctato, spatio dorsali levi; 
elytris conspicue punctato-striatis, apice obtusissime truncatis ; corpore subtus subtiliter griseo-tomentoso ; 
-mesosterno fere plano, declivi, tuberculo minuto armato; antennis griseo-rufescentibus, articulis apice — 
fuscis, scapo valde elongato. 
Long. 6 lin. 
Hab. Mexico, Paso del Macho (Hoge); Costa Rica, Cache (Rogers).
