Taxonomic value of Genilal Armature in Lejji dopier a. 319 



is furnished with a central very strong spine surrounded by 

 smaller ones in a bunch of hairs. This species I have taken 

 out of the genus Pentila and made the type of the genus 

 Ornipholidotos. I have selected Pentila abraxas for com- 

 parison with it, as it in many respects is nearer than others 

 and is a well-known insect. The tegumen (very different 

 from 0. muhata) is very ample and broad with a joined apex, 

 which is a very close approximation to the uncus of Gosse, 

 so well known in the genus Papilio. It terminates in the 

 shape of a robust horn, well excavated below, from which 

 are developed at the rear two longish heavy lobes, which 

 with the uncus-hke extremity are furnished sparingly with 

 fine bristles ; the tergite clasps are reduced to two short 

 strong horn-hke projections well supplied with strong 

 bristles, whilst the anal orifice opens out on to the surface 

 in a somewhat trumpet-shaped organ. The sternite girdle 

 is expanded backwards and is jointed on to the tergite 

 section, which seems to form an additional covering hood 

 over the organs just described, the sternite portion de- 

 veloping into a broad hollowed long groove below the 

 sternite clasps, and expanding right in front into a heavy 

 clubbed apex furnished plentifully with strong bristles; 

 the clasps form part of the girdle by fusion rather than 

 otherwise and are very broad, terminating in a longish horn 

 strongly bristled. The aedoeagus is very long, of fairly 

 uniform width, very highly curved ; the "vas deferens" 

 being highly developed, with the vesica very large and 

 furnished copiously with robust curved teeth, the apical 

 one being extra large and prominent. Here again the 

 alliance of the two insects is evident, but the important 

 parts of the armature from the taxonomic point of view 

 would certainly lead us at once to look for other characters 

 to enable us to separate them, and these we find. Telipna 

 acraea — using the genus as is done by Aurivilhus — is closely 

 allied to the two species we have just considered in the de- 

 velopment of the tergite and sternite sections, see PI. LIX, 

 fig. 12, but parva should come out of the genus. This 

 Httle species is very interesting, inasmuch as it probably 

 forms the connecting link between the Pentila group (in 

 sens, strict.) and the Liptena group; this species, as will be 

 seen from the figure, is without the usual form of girdle, 

 it has none in the sternite section, it has its origin in the 

 rear of the upper edge of the clasps with which it is fused, 

 from whence it rises to and fuses with the tegumen, which
