2. " l\ippe 1 der Voixlerflugcl wurzelwfirls nicht gegabelt, einfach." 



3. " Kippe 5 der A'orderHugel iiabe an der Kippe 4 entspringeud." 



These two characters the Ajarislidae have in common with tlie Noctuidae and 

 Arctiidae. A bifurcation of the submedian nervure to the forewing is sometimes 

 ob\iously indicated by a longitudinal furrow in the basal portion of the vein. 



4. " Kippe 2 der HinterHligel nahe an der Hiuterecke der Mittelzelle eut- 

 springend." 



The position of vein 2 to the hindwings is neither amongst the Aijarintidue nor 

 in the Noctuids, Arctiids, Hypsids, etc., of great constancy, and this vein stands on 

 an average not nearer to vein 3 in the Agarisiidae than in the allied families. We 

 find the extremes in respect to the position of vein 2 of the hindwings in Agarista 

 agricola (Don.), Phalaenoides latimis (Don.), Euthisanotia argentata Druce, with vein 

 2 coming from near vein 3, and on the other hand in Pais pidchra Trim., OharUiua 

 amabiiis (IJrury), and Eusemia mollis Wlk., in which that vein originates before the 

 apical third of the cell. 



5. " Kippe 3 uud 4 der llinterflugel aus einem Punkte (der Hiuterecke der 

 jSlittelzelle), oder mit sehr kurzem gemeinschaftlichen Stiel entspringend." 



This character applies to many Agaristidae, Koclmdae, Arctiidae, etc., but is by 

 no means met with in all Agari>tids ; vein o is removed from 4, though it always 

 stands nearer to 4 than to 2, in many species of various genera, most ob\iously so in 

 Eaaeiiiia 'iiioUis Wlk. and Agarista liictifera.Boisd. 



6. " Eippe 5 der Hinterflugel aus der Milte der koukaven (^uerripjie ausgeheud." 

 Prof. Karsch {I.e.) thinks this character the most important one, and sufficient 



to distinguish the Agaristidae from their allies by. In tlie Arctiids, Hypsids, and 

 most Noctuids, etc., vein 5 of the hindwings comes ft-om the lower angle of the cell, 

 or from between lower angle of the cell and middle of the discocellular veinlets. In 

 a great number of Noctuids vein 5 approaches the centre of the discocellulars ; in 

 others it comes just from below the centre ; while in others again, as in Heliothis Tr. and 

 some allied forms, it originates exactly from the middle of the apex of the cell. We 

 can, in fact, draw np a series of genera which show every intergradation between the 

 two extremes, the position of vein 5 at the lower angle of the cell and the position in 

 the centre of the discocellulars ; compare Barasa Wlk., Chariclea Steph., Agrotis 0., 

 Asperasa ^Moore, Erastria 0., Bryophila Tr., Heliothis Tr. And this occurrence of 

 iutergradations makes it probable to me that not all the species of Noctuoid moths 

 with vein 5 coming from the middle of the discocellulars are true Agaristidae, and 

 that there might be true Agaristidae with fliat vein originating below the centre 

 of the discocellulars. Even if we admit Heliothis Tr., Glottalu Gueu., SpheUa 

 Wlk., and some other genera to be Agaristids, there remain many others, like 

 Eupsephopaectes proci/nctus Grote fi-om California, which I cannot convince myself 

 to be anything else but Noctuidae in spite of vein 5 to the hindwings having the 

 same position as in Episteme Hiibn. (Eusemia Dalm.). On the other hand, in a 

 number of true Agaristidae, in A. alboiicargiiuUa"M.ooi-e, aviatrix W'estw., semper!. 

 Feld., hesqjenoides Wlk., and others, there is a peculiarity in the neuratiou of the 

 hindwings — explained on p. 37 — which gives vein 5 the appearance of coming from 

 near the lower angle of the cell. In Ph/daenoide$ albamedia Luc. vein 5 stand.s 

 below the middle, owing to the development of a stridulating organ ; and, alas, in 

 Agarista belangeri Guer. vein 5 is decidedly depressed at the base, as it is in typical 

 Arctiids, Hypsids, etc. 



In Agarista agricola Dun. and its nearest allies vein o stands nearer to C tlian to 4.
