284 RHOPALOCERA. 



the light pale sub marginal band quite so strongly shown as in Hewitson's figure ; but 

 they agree with our Central-American examples, and we have no doubt all belong to 

 the same species. 



We have a specimen from the Kaden collection purporting to be a type of Herrich- 

 Schaffer's E. ceculus ; it clearly belongs to Hewitson's B. auginus. 



The male genitalia have a tegumen ending in a short blunt point cleft at the end, 

 near which on either side is a short blunt semi-erect projection ; the harpagones have 

 a rounded end, near which, on the dorsal edge, is a prominent lobe, carrying a short 

 point on the inner edge. (See Tab. LXXV. fig. 26.) 



22. Eudamus auginulus, s P . n. (Tab. LXXV. figg. 20, 21, 22 s .) 



E. augino similis, sed capite et corpore supra murinis haud viridi lavatis, punctis subapicalibus irregulariter 

 positis, medio minimo ab apice quam caeteris magis distante ; plica costali obvia. 



Hab. Mexico, Paso de San Juan (Schaus) ; Guatemala, Zapote (Champion). 



We have two specimens of this butterfly before us ; they appear at first sight to be 

 inseparable from E. auginus of Hewitson, but there is no trace of green on the head, 

 body, or secondaries beneath ; likewise the subapical spots are only three in number 

 instead of four, and the middle one is very small, thus rendering their position 

 irregular. 



The male genitalia differ in many respects from those of the other species of this 

 group; the tegumen is cleft at the end into two truncate tooth-like points; the 

 scaphium is well-developed and upturned ; the harpagones end in a blunt point, on 

 the dorsal edge near the base is a prominent tooth, the point directed outwards, and at 

 the base of the disc a lobe with strong serrations. (See Tab. LXXV. fig. 22.) 



23. Eudamus octomaculatus. (Tab. LXXV. fig. 23 <$ .)

Alis murinis ; anticis maeulis tribus medianis, una costali bifida, altera in cellula, tertia infra earn, puncto 

 extra eas et tribus subapicalibus semihyalinis ; maeulis duabus indistinctis fuscis supra venam sub- 

 medianam, una ad angulum analem, altera mediana ; posticis fasciis duabus indistinctis fuscis, una discali 

 altera cellulari; ciliis sordide albis : sub tus fere ut supra, area interna anticarum pallida; palpis et pectore 

 flavido-albis ; plica costali nulla.

There can be little doubt that our specimens referred to above belong to the species 

 described by Sepp as H. octomaculata, but whether Goniuris decussata of Menetries 

 from Haiti is referable to the same insect is questionable. In the absence of specimens 

 from the typical country we are inclined to think not, as Menetries's figure shows no 

 indication of the small hyaline spot outside the central band of the primaries, which is 

 present in all our specimens and in Sepp's figure.
