reason for abandoning the older name ; the names are close but not 

 identical, and there is little danger of any confusion arising, Latreille's 

 genus being in the Coleoptera. 



Felder's definition of the genus, based on a female specimen, is 

 as follows: 



"Caput mediocre, porrectum, villosum. Oculi nudi, prominentes. Antennae 

 crassiusculae, sat longae, costae dimidium aequantes, in clavam elongatam sub- 

 rectam apice mucrone brevissimo terminatam incrassatae, distinctae articulatae. 

 Maxillae spirales longae, sat angustae. Palpi breves, dense squamatovillosi, 

 sursum ascendentes, capitis verticem non aequantes, approximati, articulo primo 

 secundo dimidio breviore, tertio minimo, obtuso pennicilliato-setoso. Thorax 

 valde convexus, ovatus, robustus, dense villosus. Alae elongatae, integerrimae, 

 basi dense villosae, venis validis, ciliis latis variegatis, cellulis clausis. Alae 

 anticae trigonae acutae, costa subrecta, niargine externo convexo, costalis dimi- 

 dium aequante, interno subrecto, costa breviore, disco paginae inferioris villo 

 longiore tecto, cellula angusta, vena costali recta, post costae medium desinente, 

 vena subcostalis quinque-ramosa, ramis intervallis aequalibus ante cellulae ex- 

 timum ascendentibus, vena discoidali prima ramo ultimo subcostali valde ap- 

 proximate, secunda remota, ad venae demianae extimum oriente. vena disco- 

 cellulari incurvata, vena mediana triramosa, ramis intervallis longis inter se 

 distantibus. 



Alae posticae costa arcuata, antice dilatata, angulo apicali subproducto, anali 

 subtruncato, calcaribus binis praecostalibus validis, cellula praecostali angustis- 

 sima, vena costali subrecta, post costae medium desinente, ramis binis subcostali- 

 bus intervallo sat longo distantibus, secundo ad cellulae extimum oriente, vena 

 discocellulari distincta, incurvata, vena discoidali a ramis subcostalibus valde 

 remota. basi arcuata, ramis tribus medianis approximatis rectis, vena sub- 

 mediana et postmediana parum distantibus. 



Pedes validi, femoribus tibiisque longe villosis, tibiis inermibus, femore 

 tertia parte brevioribus. tarsis subtus spinulosis, quinque articulatis, articulo 

 primo longissimo, tibiam fere aequante, ungulis minutis curvatis. Abdomen 

 subconicum robustissimum." 



The genus is placed in the Hespcriidac, near Pamphila, and Felder 

 further remarks that "though the antennae and habitus resemble 

 Castnia, the lack of the frenulum, the venation, and the hairy clothing 

 of the wings point without doubt to the Rhopalocera, especially to the 

 Hesperidae." 



Butler and Druce erroneously refer the genus to the Castniidae, a 

 proceeding which is followed by Druce in the Biologia Cent. Am. 



Mabille in the Genera Insectorum defines the genus Acentrocneme 

 as follows: 



"Palpes et antennes comme dans le genre suivant. (d'apres une figure). 

 Ailes superieures ; nervure 5 fortement courbee a sa base ; 3 tres eloignee de
