800 NOVITATES ZOOLOGICAE XXII. 1915. 



We have two new geographical forms : 



8a. A. amoena virgata snbsp. uov. 



(J ? . Alae anticae trivirgatae. 



Hah. Luitpokl Mts., near Ikntha, British East Africa, 4 <J c? and 1 ?. 



The spots of the forewing form three hands, the first and second bands more 

 regular than in those specimens of true amoena, from German East Africa, in which 

 the subbasal and median spots are joined together as two bands. The third 

 band of rirgata more or less constricted, on the right wing of the ? specimen 

 separated into two spots. Tlie green-black discal spot of the hindwing small, 

 either isolated (type) or joined to the marginal band. 



8^. A. amoena angolana snlisp. nov. 



?. Alarum anticarnm maculae cxteriores triangulares, superior apicem npproxi- 

 mata; posticarnm fascia marginalis ad costam medianam inferiorem in dentem 

 angustam vel brevem prodncto. 



Hab. Angola: Loanda, Februar)- 8, 1875 (Swart, ex coll. Horaeyer), 1 ? 

 (type), and " Angola littoralis " (Welwitsch, ex coll. Felder), 1 ?. 



The subbasal and median spots of the forewing form two bands ; the subapical 



spot triangular, pointed distally and posteriorly, nearer the apex than in trne 



amoena ; the snbmarginal spot also triangnlar ; its costal side shortest, its 



proximal edge about parallel with the median band, but straight, slightly longer 



than the outer edge. The marginal band of the hindwing on the whole narrower 



than in trne amoena, with a short blunt tooth at 5P reaching halfway to cell ; in 



second sj)ccimen (type) the tooth replaced by a narrow band which reaches apex of 



cell, but is more or less diffuse, being on the nnderside represented by a few scales 



only. 



Neoprocris gen. nov. 



S. Alarum anticarnm costae subcostales T', 2", 3"' liberae, 4' et .5" cnm ramo 

 1" radiali petiolatae; posticarnm costa V radialis absens. 



Genotypus : N. saltuaria spec. nov. 



Tongue well developed. Frons more than twice as broad as the eye is wide in a 

 frontal aspect, not obviously projecting. Antenna very slender, bipectinate, last ten 

 to twelve segments dentate, the pectinations about twice as long as the shaft is 

 broad. Foretibia with broad spur, which reaches a little beyond tip of tibia ; 

 hindtibia with one pair of spars. 



Neuration : forewing with twelve veins, subcostals 1, 2, 3 free into costal 

 margin, 4 and 5 on a long stalk, which throws off near cell radial I, radial 3 from 

 lower cell-angle halfway between radial 2 and median I, median 2 as far ])roximal 



as first subcostal. Hindwing with seven veins distributed as in Acoloitlius basalts 



Edw. (1887), cross-vein between costal and subcostal long, longitudinal, slightly 

 oblique. 



Differs from all the other known American Zygaenidae in subcostals 4 and 5 

 and radial 1 being stalked. To be placed before Seryda Walk. (1850). 



9. Neoprocris saltuaria spec. nov. 

 f?. Viridis, nitens; alls anticis viridibns hebetibus angustissime cyaneo cir- 

 cnmdatis, posticis nigris parum olivaceo-virescentibus ; infra posticis et anticarnm 

 regione anteriore viridi-nitentibus.
