( Ofin ) 



Tliinl stage (one sjiecimen) : yelldw, reddisli ut sides ; slightly tapering iu 

 front, Imt tlie grannlose head rather large ; pale dots present, liairs vestigial ; 

 horn red at base, tubercles black, tip narrowed to an almost smooth point ; a 

 yellow dorso-lateral line from mesonotnm to liorn, annulets obviously raised within 

 this line. 



Fourth ( last) stage (one specimen) : like the previnus, bnt tapering in iVunt, 

 horn comparatively shorter. 



I'upa (of miirf/inata) pale clay colour, punctures and grooves brcvn, labrnm 

 black, dorsal line brown; tongue-case not carinate, very little projecting frontad ; 

 labrnm terminal ; head ronnded ; anterior femur not visible ; abdomen jjunctnred, 

 jiraespiracular area of fourth and fifth segmentsnot carinate, bnt the anterior edges 

 t)f the ])nnctnrcs here more raised ; anal segments deeply impressed ventrally : 

 cremaster somewhat flattened, dispersedly punctured at base, smooth, conical in 

 dorsal view (tip broken ; PL LXIV. f. -,'3). 



Ilah. Aethiopian Region inclusive of Madagascar. 



Thirty-one species ; many more will be discovered wlien the hetencerons 

 Lepidojitera of Africa become better known. 



Allied to Ni'phrlr, from which it is easily distinguished hy the spnrs being 

 without coml) of spines. 



The species with entire wings and those with dentate or lob.iti' distal margin 

 are connected liy intergradations ; the saiue a])plics to the forips with acute and 

 with obtuse or truncate apex of fore'wing. 



From this genus several otliers have originated by the loss or rednction of 

 organs and the acquisition of new structures. The reduction of the antennal end- 

 segment and the loss of the 6 friction-scales characterises Temnoripnis ; 0(/ontos/(/ii 

 agrees with this, bnt is further advanced in having lost the ventral lobes of the 

 paronychium and the patch of seusory hairs at the base of the palpns, and acquired 

 the terminal claw to the foretibia ; Splnngonaejiiopsis is still more specialised in the 

 f;ui-like scaling of the first paljial segment, the more strongly clubbed antenna, 

 which is dentate or pectinate in S, and the acquisition of spines to the tibiae ; 

 and Micro.yt////hr represents the end of this series, having the distal segments of 

 the antenna unusually broad and short, and being witbunt tlio proximal pair of 

 hindtibial spurs (the only instance among the SjililngidKr si'tnanojihrmii' where 

 these spurs are absent). From Temnora jt)/las and allies (respectively theii- 

 ancestor) branched off (iiirclra in which the distortion of the costal margin of the 

 hindwing, indicated in Ti'innora /)sr/i(loiii/l((s, is carried out in a similar way as in 

 the Ambulicine genus Def/imipitei-a, and in which the antennal end-segment has 

 become short and the tibiae acipiired spines. These lines of develojiment are quite 

 similar to those found in the subHxmily AnihuUchiac, resulting in weak forms. 

 Entirely different is the line Tcmnont — Afemnoni — }fiicroglo!<!<inn. Here we 

 observe the same kind of specialisation which we fonnd in the higher American 

 Sesiinae, beginning with forms cliaracterised by slender antenna, weak abdominal 

 spines, rounded midcoxal merum, truncate tail, etc., and ending with forms with 

 strongly clubbed antenna, strongly angulate mid- and hindcoxal mernm, 

 strongly spined abdomen, compressed hindtarsus with densely spinose outer 

 surface, large fantail, etc. A side-branch of this line is Antlnephrle — Ihjpac- 

 iliiliii (compare diagram, facing ]>. 4'.t'.t), the latter genus showing in one species 

 a yellow abdominal side-patch homologons to the side-patches observed in most
