3. Vacerra lachares, sp. n. (Tab. xcvii. figg. 12, 13, $ .) 



$ . Alis fuscis, anticis maculis quinque in linea obliqua, una longitudinali ad venam submedianam, secunda 

 maxima inter ramos medianos primum et secundum, tertia ultra earn, quarta et quinta apicem propioribus, 

 ea apicem proxima minutissima, macula geminata in cellula, punctisque tribus in linea obliqua subapicalibus, 

 omnibus flavo-hyalinis ; posticis maculis duabus in linea obliqua, exteriore majore et geminata, quoque 

 flavo-hyalinis : subtus ut supra, sed pallidioribus et fusco marmoratis, anticis litura magna angulum analem 

 versus flava, posticis puncto parvo in cellula et linea indistincta transversa albida angulum analem versus ; 

 palpis subtus griseis ; ciliis anticis fuscis, posticis externe griseis. 



Hab. Costa Rica, Irazu {Rogers). 



A single female only of this insect was sent us by Mr. Rogers*. It is very like the 

 same sex of V. Utana, from which it differs in having five spots in the oblique series 

 on the primaries and those on the secondaries almost parallel with the outer margin ; 

 the secondaries, too, are more uniformly coloured beneath, and the fringe is not spotted. 



b> Secondaries with a long white band towards the outer margin beneath, 

 and with a yellowish spot above. 



4. Vacerra canente. (Tab. XCVII. figg. 14, e ; 15, 16, $ .) 



¥ . Carystus canente, Butl. Trans. Ent. Soc. 1870, p. 501 \ 



Alis fuscis, stigmate concolore, anticis maculis duabus parvis in cellula, quatuor in serie obliqua infra eas, 

 secunda maxima, ultima minuta, punctisque tribus in linea transversa subapicalibus, flavo-hyalinis ; 

 posticis macula apicem versus punctoque in cellula coloris ejusdem : subtus ut supra, sed pallidioribus, 

 posticis fascia recta margine costali prope apicem ad marginem externum angulum analem versus 

 extendente alba. 



9 mari similis, sed anticis maculis in cellula confluentibus punctoque subtus in cellula posticarum absente. 



Hab. Costa Rica, Cache (Rogers). 



The type of this species, a female, from an unknown locality 1 , is in our collection, and 

 we also possess a pair from Costa Rica, the female agreeing with it. The male, as in 

 V. egla, differs from the female in having the hyaline spot in the cell of the primaries 

 separated into two. V. canente is extremely like V. Utana on the upperside, but has 

 the secondaries very differently coloured beneath. We figure a female specimen, 

 also the genitalia of the male, for which latter see Tab. XCVII. fig. 14. 



TIRYNTHIA, gen. nov. 



Goniloba conflua, H.-S., is one of the numerous isolated forms of Tropical-American 

 Pamphilinee that we are compelled to place by themselves. G. conflua agrees with 

 Oxynthes (type, Goniloba corusca, H.-S.) in general coloration, but the primaries are 

 without a brand, the secondaries are broadly but shortly lobed at the anal angle, the 

 body is very robust in both sexes, the middle tibiae are without spines, the genitalia are 

 different in structure, &c. Tirynthia also approaches Niconiades and Vacerra. From 



* We have an unnamed male insect from Colombia very like V. lachares, but it has the spots on both wings 

 somewhat differently placed, and the primaries are without a brand.
