Life Histories in the Hepialid (h'mop of Lepidoptcra. 421 



definite tubercle base, only occasionally a slight discoloured 

 area round seta indicates the tubercle base, I have there- 

 fore used the general term swelling rather than tubercle 

 in my descriptions of the species. 



I have made notes on the pupa elsewhere. Imagines 

 described by E. Mcyrick, " Trans. New Zealand Institute," 

 vol. xxii, with synonymy. It is the only species of 

 Charagia in New Zealand. 



4. My friend Mr. H. E. Bacot in 1899 sent me a parcel 

 of Ilcpialidin from S. Africa about one hundred specimens, 

 comprising three or four species, at least one of which so 

 far as I can learn is unnamed. For the purpose of this 

 paper it is necessary to describe and name this species ; 

 tlie British Museum collection contains two other species 

 of the genus awaiting description. 



Gorgopis hacotii, sp. nov. (PI. V, fig. 1.) 



^ 2.5 mm. Head greyish brown above, dark brown 

 beneath. Thorax grey. Abdomen pale brown. Antennae 

 ferruginous, segments securiform. Legs of normal size, dark 

 brown above, grey beneath. Fore-wings: a characteristic 

 white band from base along lower side of cubitus to 

 middle, curves from cubitus to apex of wing; area above 

 the band is pale brown, greyish costal streak, brown line 

 on extreme costal margin ; below the band is edged with 

 brown, the lower and outer area of wing greyish. Cilia 

 brownish edged with grey. Hind-wings : concolorous pale 

 brown, cilia as on fore-wings. 



Florida ; South Africa. 



Common. Markings constant, no variation in my series 

 of eleven specimens. 



5. Probably the genus Hcpiahcs preserve among them 

 more extensively than any other genus of the group, the 

 structural character of primitive Hepialidie-, at least in the 

 imago. It seems anomalous, however, that the present 

 distribution of Hcpialus — and subgenera — is so extensive 

 and connected, ranging throughout Europe, Asia, Austral- 

 asia, North and Soutli America, but not in Africa ; and 

 yet species of more specialised genera are isolated and 

 disconnected in distribution. Porina {Elhcuiiitia, Walk.), 

 essentially an Australasian genus, has one representative — 

 P. niphadias, Meyr. — in Patagonia; Lcto, Hubn., a genus
