LEPTURGES. 
Lepturges, Bates, Ann. & Mag. Nat. Hist. ser. 8, xii. p. 8367 (1863) ; Horn, Trans. Am. Ent. Soc. 
viii. p. 126 (1880). 
Dr. Horn has improved the definition of this genus by adding to the characters I 
originally gave a further one drawn from the pro- and mesosterna, both of which, as he 
correctly states, are very narrow and barely wide enough to separate the coxe. In the 
more typical species the front of the head is short, and the lower lobes of the eyes 
voluminous as in Anisopodus; the epipleura of the elytra, however, are not strictly 
vertical or separated from the dorsal surface by a sharp line; and the hind femora are 
linear or but obliquely thickened. The less typical species have clavate femora, and 
in some cases are scarcely distinguishable from Leiopus. Inall, the thorax has a sharp 
lateral spine, either close to, or a short distance from, the hind angles, the space 
between the angle and the spine, in the latter case, being deeply sinuate. 
About fifty species, including those about to be described, are known, all from 
Tropical and North America.

3. Lepturges macilentus. 
L. infilato et limpido proxime affinis, differt corpore multo angustiore, lateribus magis parallelis, elytrisque 
supra minus variegatis. Angustus, elongatus, depressus, rufescens, griseo subtiliter tomentosus, thorace 
vittis obsoletis, elytris lineola parva prope scutellum, macula humerali, plaga elongata dilacerata mediana 
intus ramum angustum angulatum usque ad suturam emittente fasciaque dentata abbreviata ante apicem 
fusco-rufescentibus ; thorace trapezoidali elongato, spina laterali (conica, acuta) juxta angulum sita, mar- 
gine obliquo inter spinam et basin; elytris elongatis, apice singulatim rotundatis; antennis pedibusque 
rufescentibus, griseo tomentosis. 
Long. 33 lin. 
Hab. Mexico, Cordova, Playa Vicente (Sallé). 
The long and irregular medio-lateral patch of the elytra is connected by slender 
branches both with the spot under the shoulders and the short flexuous anteapical 
fascia. ‘The species resembles most closely, in colours and markings, L. lémpidus; but 
it is of much narrower form, and the lateral spine of the thorax is nearer the hind
